Answer: FALSE Learning Outcome: 1.6 Bloom's Taxonomy: 1-2: Remembering/Understanding 1.3 Essay Questions 1) How does the regional approach differ from the systemic approach in the study of anatomy? Answer: Systemic anatomy considers all of the components of each organ system simultaneously, regardless of body location. Regional anatomy considers all of the superficial and internal structures in a specific area of the body, regardless of the organ system. Learning Outcome: 1.2 Bloom's Taxonomy: 3-4: Applying/Analyzing 2) How does comparative anatomy contribute to the study of human gross anatomy? Answer: Observed similarities of anatomical structure among different species of animals demonstrate evolutionary relationships and the similarity of developmental processes. Comparison of the same systems among different animals also shows how these systems are adapted to serve different anatomical and physiological functions. Learning Outcome: 1.3 Bloom's Taxonomy: 3-4: Applying/Analyzing 3) What is the basic anatomical pattern that humans and other vertebrate animals share? Answer: All of these organisms have a braincase of cartilage or bone that surrounds the brain. All vertebrates have a dorsal hollow nerve cord and ventral body cavities. At some stage of development (often only embryonic), vertebrates also have a notochord, a muscular tail and pharyngeal (gill) arches. Learning Outcome: 1.3 Bloom's Taxonomy: 3-4: Applying/Analyzing

4) How does improper functioning at the chemical level affect cellular, tissue, organ, and organism function? Answer: Each complex level is totally dependent upon all the levels that are less complex, therefore damage at the level of the smallest structure affects larger and more complex structures throughout the system. For example, the inability of a protein to function in a cell causes improper functioning of the cell. The faulty cell then leads to a tissue that is not fully capable of its functions. The organ is affected by the development of defective tissue. Finally, the entire organism is affected because the organ is not functioning properly. Learning Outcome: 1.4 Bloom's Taxonomy: 3-4: Applying/Analyzing 5) In general, why must larger organisms have specialized structures to permit some life functions to occur? Answer: The organismal level of organization reflects the interactions among organ systems, all of which are vital. In other words, every system must be working properly and in harmony with every other system, or survival will be impossible. In large organisms, for example, specialized structures are required for movement of materials through exposed surfaces and transport of materials between body regions because (1) many cells are too far from an exposed surface and (2) there is not enough total surface area to allow all of the body's cells to exchange nutrients, oxygen, and wastes directly with the environment. Other life functions, such as reproduction, are also complicated by organisms' larger size. Learning Outcome: 1.5 Bloom's Taxonomy: 5-6: Evaluating/Creating 6) What is the function of an organ system in the body? Answer: Organ systems are groups of organs that function together to produce coordinated effects, such as the example of the cardiovascular system, which consists of the heart, blood, and the network of blood vessels (circulatory system). Learning Outcome: 1.5 Bloom's Taxonomy: 1-2: Remembering/Understanding 7) What is the role of serous membranes in the body? Answer: Serous membranes provide a slippery cover for the inside of the body cavities (ex. pleural cavity) and the outside of most organs located in these cavities (ex. the lung). This slippery lining prevents friction between moving organs and the body wall. Learning Outcome: 1.6 Bloom's Taxonomy: 1-2: Remembering/Understanding 8) Why is radiographic anatomy an increasingly important science? Answer: The specialized radiographic procedures, which are performed on an intact body, include non-invasive techniques that use radioisotopes, radiation, and magnetic fields to provide detailed information about and images of internal systems and structures. Such information can be gathered in a non-invasive manner and a diagnosis can often be reached almost immediately after many procedures.

9) How does the definition of posterior, as it is used in human terminology, differ from the usage with four-legged animals (quadrupeds)? Answer: Posterior means "behind," which is equivalent to dorsal ("the back") in humans. Because of the difference in standing position, the two terms are not equivalent in quadrupeds, dorsal still meaning the back of the animal, but posterior meaning the tail (or caudal) end. Learning Outcome: 1.6 Bloom's Taxonomy: 3-4: Applying/Analyzing 10) Why is it important for all health care professionals to understand anatomical/medical terminology? Answer: Effective communication begins with speaking, writing, and reading the same language. In effect, anatomy uses a special language that must be learned at the start. Just as an individual who does not speak Spanish is lost in Spain, an individual who does not understand the language of anatomy is lost in the hospital.

Answer: TRUE Learning Outcome: 2.1 Bloom's Taxonomy: 1-2: Remembering/Understanding 2.3 Essay Questions 1) Why is it potentially harmful to give a patient intravenous fluid that is pure water? Answer: Body fluids (extracellular – ECF and intracellular fluids – ICF) are not comprised of pure water, they are a mixture of water and solutes. The addition of water without solutes causes an imbalance in the body between the amount of water compared to solute, which dilutes the body fluids. More specifically, the plasma membrane plays a major role in sensitivity in that it is the first part of the cell to be affected by changes in ECF. It contains a variety of receptors that allow the cell to recognize and respond to specific molecules in its environment and to communicate with other cells. Any alteration in the plasma membrane, such as exposing it to only pure water, may affect all cellular activities. Its functional role in physical isolation of the cell from the surrounding ECF is important because the composition of the cytoplasm is very different from that of the ECF, and that difference must be maintained for survival. The ultimate outcome will result in the lysing (bursting) of red blood cells. As a result, the kidneys may become overwhelmed while attempting to rid the bloodstream of the products of this destruction. Learning Outcome: 2.1 Bloom's Taxonomy: 5-6: Evaluating/Creating 2) Solutions A and B are separated by a selectively permeable barrier. Over time, the level of fluid on side A increases. Which solution initially had the higher concentration of solute? Answer: Side A had the higher solute concentration, as osmosis is drawing water to it and out of solution B. Learning Outcome: 2.1 Bloom's Taxonomy: 5-6: Evaluating/Creating 3) Explain why an animal cell without centrioles cannot divide. Answer: Centrioles are a structure used during mitosis of cell division. During metaphase and anaphase, the centrioles direct the organization of the microtubules of the cytoskeleton, hence the movement of daughter chromosomes to opposite ends of the cell so that cytokinesis will result in two daughter cells, each containing its own set of chromosomes. Learning Outcome: 2.1 Bloom's Taxonomy: 3-4: Applying/Analyzing

4) Predict the consequences of non-functional cilia in the respiratory airways. Answer: Cilia lining the respiratory tract beat in a synchronized manner to move sticky mucus and trapped dust particles toward the throat and away from delicate respiratory surfaces. This cleansing action is lost if the cilia are damaged or immobilized by heavy smoking or some metabolic problem, and the irritants will no longer be removed. As a result, chronic respiratory infections develop. Learning Outcome: 2.1 Bloom's Taxonomy: 5-6: Evaluating/Creating 5) What is the role of the Golgi apparatus in cellular metabolism? Answer: The Golgi apparatus synthesizes and packages secretions, such as enzymes that store, modify, and package the proteins and glycoproteins arriving from the RER via transport vesicles. Among the vesicles that are packaged by the Golgi and remain in the cytoplasm are lysosomes, which are filled with enzymes that digest damaged membranous organelles. Learning Outcome: 2.1 Bloom's Taxonomy: 1-2: Remembering/Understanding 6) How does the plasma membrane change either over time or in response to modifications in the extracellular fluid? Answer: Membrane turnover (renewal or modification of the plasma membrane) is performed by the Golgi apparatus, which continually adds new membrane to the cell surface and can alter the membrane properties as required. In an actively secreting cell, the entire surface area of the plasma membrane may be replaced in as little as an hour. Learning Outcome: 2.1 Bloom's Taxonomy: 1-2: Remembering/Understanding 7) Distinguish between primary and secondary lysosomes; how do they function? Answer: Primary lysosomes contain inactive enzymes; activation of these enzymes occurs when the lysosome fuses with the membrane of damaged organelles. This forms a secondary lysosome, which contains activated enzymes that act to break down the engulfed contents. These contents then either reenter the cytosol (if nutrients) or are eliminated by exocytosis (if toxins or wastes). Learning Outcome: 2.1 Bloom's Taxonomy: 3-4: Applying/Analyzing 8) How do peroxisomes differ from lysosomes? Answer: Peroxisomes are smaller than lysosomes, and they carry different groups of enzymes. Peroxisomal enzymes are formed by free ribosomes within the cytoplasm and then inserted into the membranes of preexisting peroxisomes, whereas the Golgi apparatus packages digestive enzymes, formed by the rough endoplasmic reticulum (RER), into lysosomes. Peroxisomes absorb and break down fatty acids and other organic compounds; lysosomes perform essential intracellular cleanup, recycling, and defense, all by activating and/or releasing their digestive enzymes under appropriate circumstances. Learning Outcome: 2.1 Bloom's Taxonomy: 3-4: Applying/Analyzing

9) How does the structure of a tight junction differ from that of an anchoring junction? Answer: At a tight junction, the lipid portions of the opposing plasma membrane are tightly bound together by interlocking membrane proteins, providing the strongest of intercellular connections. At an anchoring junction, the two plasma membrane remain distinct but are powerfully attached by CAMs (cell adhesion molecules) and a layer of proteoglycans (intercellular cement), with a dense area of layered proteins inside each plasma membrane, reinforcing the junction and binding it to the cell's cytoskeleton. Learning Outcome: 2.2 Bloom's Taxonomy: 3-4: Applying/Analyzing 10) What is cytokinesis? What is its role in the cell cycle? Answer: Cytokinesis is the process by which daughter chromosomes approach the ends of the spindle apparatus. The cytoplasm then constricts along the plane of the metaphase plate, forming a cleavage furrow that deepens until the two daughter cells are separated; thus, completing their physical separation at the end of mitosis. The completion of cytokinesis marks the end of cell division and the beginning of the next interphase period (a new cell cycle). Learning Outcome: 2.3 Bloom's Taxonomy: 1-2: Remembering/Understanding 11) Explain why adult animals and plants replace many of their cells throughout their lifetimes. Answer: Cells can be damaged by physical wear and tear (abrasion), toxic chemicals, pathogens, temperature changes, or other environmental hazards. Since cells have variable life expectancies, they are also lost due to aging and must therefore be replaced. Learning Outcome: 2.3 Bloom's Taxonomy: 3-4: Applying/Analyzing

3.3 Essay Questions 1) What are the main structural differences between cartilage and bone? Answer: In cartilage, blood vessels are absent and chondrocytes occupy lacunae; whereas, in bone, vascularity is extensive and osteocytes reside in lacunae. Cartilage has a matrix that is equivalent to a firm gel, consisting of chondroitin sulfates with proteins that form hydrated proteoglycans, and collagen, elastic, and reticular fibers whose proportions vary according to the type of cartilage. This combination gives cartilage the quality of limited strength in that it bends easily but is difficult to break. In contrast, bone matrix is comprised of insoluble crystals of calcium phosphate and calcium carbonate, and collagen fibers predominate. Together, these constituents attribute the quality of strength and limited flexibility to bone, making it very resistant to shattering. Other structural and characteristic differences are as follows: cartilage is externally covered by a 2-layered perichondrium; bone is covered by a 2-layered periosteum; cartilage has low oxygen demand and receives nutrients by diffusion through the matrix; whereas, bone has high oxygen demand and receives nutrients by diffusion through the cytoplasm and fluid in canaliculi. Learning Outcome: 3.2 Bloom's Taxonomy: 3-4: Applying/Analyzing 2) In what regions of the body could you expect to find dense irregular connective tissue, and why would the tissue be located in these regions? Answer: Dense irregular connective tissue is found in the dermis, where it gives the skin strength and allows it to resist stresses from many directions. Except at joints, dense irregular connective tissue also forms a sheath around cartilage (the perichondrium) and bone (the periosteum), thus mainly providing external protection. It also forms a thick, fibrous capsule that surrounds many internal organs, such as the liver, kidneys, and spleen. And it encloses the cavities of joints. Its function in these cases is to also provide strength and support to such areas subjected to stresses from many directions. Learning Outcome: 3.2 Bloom's Taxonomy: 3-4: Applying/Analyzing 3) How does a ligament differ from a tendon? Answer: Tendons are cords of dense regular connective tissue that attach skeletal muscles to bones and cartilage. The collagen fibers run along the longitudinal axis of the tendon and transfer the pull of the contracting muscle to the bone or cartilage. Although ligaments resemble tendons, they function solely to connect cartilage-to-cartilage, bone to cartilage, and one bone to another. Ligaments may contain significant numbers of elastic as well as collagen fibers, and therefore can tolerate a modest amount of stretching. Elastic ligaments have a higher proportion of elastic fibers and are found in such locations as along the spinal column, to stabilize the positions of the vertebrae. Learning Outcome: 3.2 Bloom's Taxonomy: 3-4: Applying/Analyzing

4) Why is skeletal muscle called striated voluntary muscle? Answer: Skeletal muscle fibers are called striated because they have a banded, or striated, appearance due to the presence of actin and myosin filaments, which are arranged in parallel within organized functional groups. Skeletal muscle is considered a voluntary muscle because the fibers normally will not contract unless stimulated by nerves, and the nervous system provides voluntary control over their activities. Learning Outcome: 3.5 Bloom's Taxonomy: 3-4: Applying/Analyzing 5) Why is the ability of cardiac muscle to repair itself more limited than that of smooth muscle? Answer: Cardiac muscle fibers are incapable of dividing, and cardiac muscle tissue lacks myosatellite cells, which divide to produce new muscle fibers. Thus, cardiac muscle tissue damaged by injury or disease cannot regenerate. However, smooth muscles cells can divide, and smooth muscle tissue can therefore regenerate after an injury.

9) In aging humans, the blood supply to the dermis is increased at the same time that sweat glands become less active. Answer: FALSE Learning Outcome: 4.7 Bloom's Taxonomy: 1-2: Remembering/Understanding 4.3 Essay Questions 1) How does melanin protect the skin from the effects of ultraviolet light? Answer: Melanin protects the skin from damage by absorbing the ultraviolet radiation before it damages chromosomes in the nuclei of cells in the epidermis and dermis. In other words, it functions as a limited shield against UV damagefor the nuclei Learning Outcome: 4.2 Bloom's Taxonomy: 1-2: Remembering/Understanding 2) What is the clinical importance of tension lines / cleavage lines of the skin? Answer: Tension lines are important because a cut that runs parallel to them will usually remain closed; whereas, a cut at right angles to tension lines will sever elastic fibers in the skin and thus be pulled open as they recoil. Therefore, a parallel cut will heal faster and with less scarring than a cut at right angles to tension lines. Learning Outcome: 4.3 Bloom's Taxonomy: 3-4: Applying/Analyzing 3) What is "baby fat" and what is its importance? Answer: "Baby fat" is extensive subcutaneous fat in infants and small children. This subcutaneous fat helps to reduce heat loss and serves as a substantial energy reserve and shock absorber for babies, who experience many bumps as they learn to walk and accomplish other physical activities. Learning Outcome: 4.4 Bloom's Taxonomy: 3-4: Applying/Analyzing 4) What are the main differences between sebum and eccrine sweat? Answer: Sebum is a waxy, oily lipid secretion discharged by the sebaceous glands. It provides lubrication on the surface of the skin and inhibits the growth of bacteria. Eccrine sweat is a watery fluid, which consists of 99% water, some electrolytes (chiefly sodium chloride), metabolites, and waste products, secreted by this type of sweat glands. Eccrine sweat glands function in thermoregulation, excretion, and protection of the skin from environmental hazards. Learning Outcome: 4.5 Bloom's Taxonomy: 3-4: Applying/Analyzing

5) Predict why acne worsens at puberty? Answer: Sebaceous glands and follicles are very sensitive to changes in concentrations of sex hormones. When the concentration of these hormones increases at puberty, the sebaceous glands are stimulated to secrete greater amounts of sebum. This can block sebaceous ducts as the secretions accumulate, causing inflammation and providing a fertile environment for bacterial infection. Learning Outcome: 4.5 Bloom's Taxonomy: 5-6: Evaluating/Creating 6) How do eccrine glands function in excretion? Answer: The secretion from eccrine sweat glands provides a significant excretory route for water and electrolytes. It can also provide excretory routes for a number of prescription and nonprescription drugs. Learning Outcome: 4.6 Bloom's Taxonomy: 1-2: Remembering/Understanding 7) Why does hair turn gray or white in older individuals? Answer: As people age, hair follicles stop functioning or they produce finer, thinner hairs. Consequentially, decreased melanocyte activity results in hairs that become gray or white, due to either the loss of melanin or the presence of air bubbles in the medulla of the hair shafts.

5.3 Essay Questions 1) What kind of tissue(s) would most likely be found in a tissue sample taken from the interior of the epiphysis of the femur? Answer: Spongy bone makes up the internal framework of the epiphyses of the femur. Also found here are extensive areas of red bone marrow (important sites of blood cell formation) filling in the spaces of the spongy bone. Learning Outcome: 5.1 Bloom's Taxonomy: 1-2: Remembering/Understanding 2) What is the significance of the orientation of the trabeculae in spongy bone? Provide a specific example, discussing how trabecular structure lends to its function(s). Answer: Trabeculae grow in response to stresses on the bone, to act as buttresses in the bone; therefore, they align at right angles to the direction of the stress. For example, the trabeculae in the proximal epiphysis of the femur are oriented long the stress lines, but with extensive crossbracing. This trabecular alignment function in transferring forces from the hip across the metaphysis to the femoral shaft; at the distal epiphysis, the trabeculae direct the forces across the knee joint to the leg. In addition to reducing weight and handling stress from many directions, the open trabecular framework provides support and protection for the cells of the bone marrow. Learning Outcome: 5.1 Bloom's Taxonomy: 1-2: Remembering/Understanding 3) How does an extensive exercise program affect the appearance of the skeleton? Why do these changes occur? Answer: Because bones are adaptable, their shapes and surface features reflect the forces applied to them. For example, bumps and ridges on the surface of a bone mark the sites where tendons attach to the bone. If muscles become more powerful, as what happens as a result of an extensive exercise program, the corresponding bumps and ridges enlarge to withstand the increased forces. Heavily stressed bones become thicker and stronger, whereas, bones not subjected to ordinary stresses will become thin and brittle. Regular exercise is therefore important as a stimulus that maintains normal bone structure, especially in growing children, postmenopausal women, and elderly men. Learning Outcome: 5.3 Bloom's Taxonomy: 5-6: Evaluating/Creating 4) A boy returns to school to begin 7th grade after summer vacation only to find that he is at least four inches taller than several classmates that were the same height as him before the summer. Propose a reason for such a difference. Answer: The boy has most likely entered puberty and his classmates have not. He has experienced rapid growth as a result of increasing sex hormone levels in his body. These hormones stimulate osteoblasts to produce bone faster than the rate of epiphyseal cartilage expansion. Over time, the epiphyseal cartilages will narrow and eventually ossify, or "close." Learning Outcome: 5.3 Bloom's Taxonomy: 5-6: Evaluating/Creating

6.3 Essay Questions 1) The skull of a newborn often appears to be deformed, but after a short period of time, the skull assumes normal shape. What happens during the birth process and why does this change occur? Answer: Prior to birth, the brain enlarges rapidly. Although the bones of the skull are also growing, they fail to keep pace with the growing brain. At birth, the cranial bones are connected by areas of fibrous connective tissue called fontanelles. These connections are quite flexible, and thus allow the skull to be distorted without damage. Such distortion is only temporary and normally occurs during the delivery and eases the passage of the infant through the birth canal. Learning Outcome: 6.6 Bloom's Taxonomy: 3-4: Applying/Analyzing 2) A person with a serious case of osteoporosis has developed kyphosis. What anatomic structures are involved in this condition, and what are the functional implications? Answer: Kyphosis is the condition in which the normal thoracic curve is exaggerated posteriorly, producing a "round-back" appearance. This condition can be caused by three factors: (1) osteoporosis with compression fractures affecting the anterior portions of the bodies of T1-12 vertebrae; (2) chronic conditions in muscles that insert on the vertebrae; and (3) vertebral growth. Functional problems associated with this condition may involve the following: problems associated with the support of the head, neck, and upper limbs; a reduction in volume and a change in the shape of the thoracic cavity; compression of thoracic viscera; and perhaps contribute to circulatory and respiratory problems. Learning Outcome: 6.7 Bloom's Taxonomy: 3-4: Applying/Analyzing 3) Being in a car accident may cause the steering wheel to hit the driver very forcefully in the chest. If the damage is severe enough, the ribs may break and puncture the thoracic cavity. What is such an injury called? What symptoms and the anatomical injuries would occur? Answer: If broken ribs have punctured the pleural cavity of the lungs, it would result in the condition called pneumothorax, which is the entry of air into the chest cavity. This may lead to a collapsed lung, which would make respiration more difficult. If the lung on the side of the injury has sustained damage to a blood vessel or if the heart were damaged, it would cause bleeding into the thoracic cavity, a condition known as hemothorax. A hemothorax can also impair lung function because fluid may accumulate and compress a lung. Externally, bubbles would be observed at the site of the opening of the injury, and breathing would become labored. In real life, such an injury would require an immediate trip to a hospital emergency room. Learning Outcome: 6.8 Bloom's Taxonomy: 3-4: Applying/Analyzing

7.3 Essay Questions 1) What is the significance of the more massive pelvic bones compared to those of the pectoral girdle and the strong bone-to-bone attachments of the pelvic girdle of the lower extremity to the axial skeleton? Answer: The almost immobile joint between the auricular surfaces of the sacrum and the iliac region of the coxal bones occurs at the posterior and medial aspects of the ilium, forming the sacroiliac joint. The anterior and medial portions of the hip bones are connected by a pad of fibrous cartilage at the pubic symphysis. An extensive network of ligaments also binds the ilia to the posterior lumbar vertebrae. This ensures that the weight from the upper part of the body will be able to pass through the lower limb to the ground efficiently. The composition of the pelvic girdle also facilitates the lower limbs' function in locomotion. Learning Outcome: 7.2 Bloom's Taxonomy: 3-4: Applying/Analyzing 2) Imagine you are a forensic osteologist teaching a course on differentiating the male skeleton from the female skeleton. Justify the reasoning that the pelvis is the best area to examine. Answer: The shape of the female pelvis is somewhat different from that of the male pelvis. Some of these differences are the result of variations in body size and muscle mass. Because women are typically less muscular than men, the pelvis of the adult female is usually smoother and lighter and has less prominent markings where muscles or ligaments attach. Other differences are adaptations for childbearing. These adaptations support the weight of the developing fetus and uterus, and ease the passage of the newborn through the pelvic outlet at the time of delivery. Learning Outcome: 7.2 Bloom's Taxonomy: 5-6: Evaluating/Creating 3) How can the age of a skeleton be determined? Answer: There are general changes in the skeletal system that occur as one ages. Such changes begin at age 3 months and continue throughout life. For example, fusion of the epiphyseal cartilages begins at about age 3, while degenerative changes in the normal skeletal system, such as a reduction in mineral content in the bony matrix do not begin until age 30-45. In addition, with age there is a reduction in the size of the intervertebral discs, and a fusion of pectoral and pelvic girdles. Learning Outcome: 7.3 Bloom's Taxonomy: 3-4: Applying/Analyzing

8.3 Essay Questions 1) What are the components of a synovial joint? Answer: The outer layers of a synovial joint include a fibrous joint capsule, reinforced by thickenings, often named as separate ligaments. Inside the capsule, the articular surfaces of the bones are covered by articular cartilages, and lined by synovial membrane. Synovial membrane secretes a synovial fluid that lubricates the joint. The joint may also be cushioned and subdivided by bursae, fat pads, and menisci. Learning Outcome: 8.1 Bloom's Taxonomy: 1-2: Remembering/Understanding 2) How does a syndesmosis differ from a symphysis, even though both are classified as amphiarthroses? Answer: Amphiarthroses permit very little movement, but a syndesmosis is connected by ligaments in a region such as the connection between the distal tibia and fibula. A symphysis allows little movement also, but in this case the bones are separated by a pad or wedge of fibrocartilage, as in the pubic symphysis. Learning Outcome: 8.1 Bloom's Taxonomy: 3-4: Applying/Analyzing 3) Why are the functional requirements of the lower limb joints different from those of the upper limb? Answer: The functional requirements of the joints in the lower limb are very different from those of the upper limb because articulations at the hip, knee, and ankle must transfer the body weight to the ground. Consequently, during movements such as running, jumping, or twisting, the applied forces are considerably greater than the weight of the body. Learning Outcome: 8.2 Bloom's Taxonomy: 5-6: Evaluating/Creating 4) Why do human beings lose height as they reach old age? Answer: Since the intervertebral discs make a significant contribution to an individual's height, they account for roughly one-quarter of the length of the vertebral column above the sacrum. As an individual ages, the water content of the nucleus pulposus within each disc decreases as the gelatinous core is replaced by fibrous cartilage. The discs gradually become less effective as a cushion, and the chances for vertebral injury increase. Loss of water by the discs also causes shortening of the vertebral column, which accounts for the characteristic decrease in height with advanced age. Learning Outcome: 8.4 Bloom's Taxonomy: 3-4: Applying/Analyzing

5) How does the construction of the shoulder capsule contribute to the extensive range of motion of the shoulder joint? Answer: The articular capsule of the shoulder joint extends from the scapular neck to the humerus. It is a relatively oversized capsule that is weakest at its inferior surface. When the upper limb is in the anatomical position, the capsule is tight superiorly and loose inferiorly and anteriorly. The construction of the capsule contributes to the extensive range of motion as the bones of the pectoral girdle provide some stability to the superior surface. This stability is due to the acromion and coracoid processes projecting laterally superior to the humeral head. However, most of the stability at this joint is provided by the ligaments and surrounding skeletal muscles, and their associated tendons.

9.3 Essay Questions 1) How are oxygen and nutrients supplied to the tissues of a muscle? Answer: Each muscle has an extensive vascular supply that carries oxygen and nutrients. These blood vessels often enter the epimysium alongside the associated nerves and follow the same branching pattern through the perimysium. Once within the endomysium, they form an extensive capillary network around each muscle fiber. Learning Outcome: 9.2 Bloom's Taxonomy: 1-2: Remembering/Understanding 2) Describe the composition and the arrangement of constituents within a myofibril. Answer: Myofibrils consist of bundles of myofilaments, which are composed of several different types of proteins. Myosin and actin are the contractile proteins, which comprise the thick and thin filaments, respectively. Tropomyosin and troponin are regulatory proteins within the myofilaments, while titin and nebulin are accessory proteins. The thick (myosin) and thin (actin) filaments within a myofibril are arranged in repeating functional units called sarcomeres. All of the myofibrils are arranged parallel to the long axis of the cell, with the sarcomeres arranged side by side. As a result, the entire muscle fiber has a banded appearance corresponding to the bands of the individual sarcomeres. Learning Outcome: 9.2 Bloom's Taxonomy: 1-2: Remembering/Understanding 3) Why does a sarcomere itself appear to be banded, and what constituents comprise these bands? Answer: Since all the proteins within a myofibril are organized in repeating units called sarcomeres, such an arrangement gives the sarcomere a banded appearance. The differences in the size and density of the thick (myosin) filaments and the thin (actin) filaments account for the banded appearance of the sarcomere. The thick filaments lie in the center of the sarcomere, linked by proteins of the central M line. Thin filaments at either end of the sarcomere, which are attached to interconnecting proteins that make up the Z lines, extend toward the M line. The Z lines delineate the ends of the sarcomere. In summary, the A band of a sarcomere includes the central M line, the H band (which has thick filaments only), and the zone of overlap (which has both thick and thin filaments). Between the A band and the Z line is the I band (which has thin filaments only). From the Z lines at either end of the sarcomere, thin filaments extend into the zone of overlap toward the M line. Under polarized light, the A (anisotropic) bands appear as dark bands and the I (isotropic) bands appear as light bands. Learning Outcome: 9.2 Bloom's Taxonomy: 1-2: Remembering/Understanding

4) How is muscle contraction regulated by tropomyosin and troponin? Answer: The thin filament consists of a twisted strand, called F-actin, which is composed of two rows of 300-400 globular molecules of G-actin. A slender strand of the protein nebulin holds the F-actin strand together. Each molecule of G-actin contains an active site that can bind to the myosin heads of a thick filament. A thin filament also contains the regulatory proteins tropomyosin and troponin. Tropomyosin molecules form a long chain that covers the active sites, preventing actin-myosin interaction. Troponin holds the tropomyosin strand in place. Before a contraction can begin, the troponin molecules must change position, moving the tropomyosin molecules and hence exposing the active sites. If the active sites are covered, cross-bridge formation cannot occur and the muscle cannot contract. The interaction between calcium ions and troponin molecules is important in holding the tropomyosin strands in place, thereby exposing the active sites on the G-actin molecules. Therefore, the troponin-calcium ion interaction permits the tropomyosin molecule to change position, allowing for the contraction to begin. Learning Outcome: 9.3 Bloom's Taxonomy: 1-2: Remembering/Understanding 5) Why does a person with muscles that have a higher percentage of slow fibers have greater endurance than a person with muscles that have a lower percentage of slow fibers? Answer: A person with more slow fibers in a particular muscle will be better able to perform repeated contractions under aerobic conditions than one with a smaller percentage of this type of fibers. This is the case because the person with muscles that have a higher percentage of slow fibers will not fatigue as easily as the person whose muscles have a lower percentage. The slow fibers fatigue more slowly because the additional myoglobin they contain bind oxygen molecules, conferring substantial oxygen reserves to such muscles, which can be mobilized during a contraction. Another advantage of the higher percentage of slow fibers is a more extensive network of capillaries, which allow for greater blood flow and hence more red blood cells that can deliver more oxygen to the active muscle fibers. Learning Outcome: 9.5 Bloom's Taxonomy: 1-2: Remembering/Understanding 6) What types of changes cause muscles to decrease in size and strength during the aging process? Answer: Skeletal muscle fibers become smaller in diameter, primarily because there is a decrease in the number of myofibrils. The remaining myofibrils retain smaller amounts of ATP, glycogen reserves, and myoglobin, which results in a decrease in muscle strength and endurance, as well as a tendency to fatigue rapidly.

10.3 Essay Questions 1) What would be the consequences of a lacerated trigeminal nerve in terms of muscular control? Answer: The mandibular branch of the trigeminal nerve (CN V) controls the muscles of mastication. If laceration to CN V occurs, chewing and swallowing would be very adversely affected. Such actions involve moving the mandible at the temporomandibular joint (TMJ), in which the mandible is elevated, protracted, retracted, and moved side to side, as well as closing and opening the jaws. Learning Outcome: 10.2 Bloom's Taxonomy: 5-6: Evaluating/Creating 2) Why can one clear the ears by swallowing? Answer: There is an entrance to the auditory tube in the upper pharyngeal region, and contraction of the palatal muscles can pull on this opening. Therefore, repeated swallowing can open the auditory tube and allow the passage of air into or out of it to equalize the pressure on the middle ear caused by increasing or decreasing altitude or underwater pressure. Learning Outcome: 10.2 Bloom's Taxonomy: 1-2: Remembering/Understanding 3) Why are there so few spinal flexors associated with the anterior surface of the vertebral column, whereas there are a large number of different extensor groups? Answer: In addition to using the flexor muscles, the trunk can be assisted in forward movement by gravity. Because the bulk of the body's mass (weight) is anterior to the vertebral column, flexing the spine toward the anterior becomes easier. Learning Outcome: 10.3 Bloom's Taxonomy: 1-2: Remembering/Understanding 4) What muscular changes are involved in the breathing process? Answer: The muscles involved in respiration are the scalenes (deep breathing), the intercostals (external = rib elevation and inspiration; internal = depression and exhalation), the diaphragm for both inspiration (during contraction) and exhalation (during relaxation), and the muscles of the abdominopelvic wall, which compress the abdominopelvic cavity to raise pressures that assist in exhalation and relax to assist in inspiration. Learning Outcome: 10.4 Bloom's Taxonomy: 1-2: Remembering/Understanding 5) What are the muscles of the urogenital triangle, and how do they control the functions of this area? Answer: The urogenital triangle is the anterior half of the perineum. The superficial muscles (bulbospongiosus, ischiocavernosus, and superficial transverse perineal) in this region are those of the external genitalia, which overlie the deeper muscles (deep transverse perineal and external urethral sphincter) that strengthen the pelvic floor and encircle the urethra. These muscles form sphincters around the urinary openings in both males and females, and around the vaginal opening in females.

Answer: Hamstring injuries are classified as follows: Grade I injury is a minor strain; Grade II injury is a partial rupture of the muscle; and Grade III injury is a complete tear or rupture of the muscle. Symptoms of a hamstring injury include spasms, tightness, and tenderness of the injured muscle(s). With more severe injuries, swelling and a black and blue or bruised appearance will follow. Tears and strains most often occur where the muscle joins its tendon of insertion or at the origin of the hamstring at the base of the ischial tuberosity.

3) What emerging measures are done to relieve compartment syndrome, and what can occur if these measures are not done? Answer: Slicing into the affected muscular compartment along its longitudinal axis or implanting a drain are emergency measures used to relieve the high pressures that occur in the ischemic condition known as compartment syndrome. If such steps are not taken, the contents of the compartment will suffer severe damage. Nerves in the affected compartment will be destroyed after 2-4 hours of ischemia; although they can regenerate to some degree if the circulation is restored. After 6 hours or longer, the muscle tissue will also be destroyed, and no regeneration will occur. Scar tissue will replace the damaged muscles, and shortening of the connective tissue fibers may result in contracture, a permanent reduction in muscle length.

12.3 Essay Questions 1) How does the process of palpation reveal anatomical structures to the student of anatomy? Answer: Palpation is the use of the fingers to feel deep organs and structures through the skin of the body surface. Because the skin does not adhere closely to underlying organs in most locations, it is possible to feel the shape of the underlying structures by compressing and moving the skin over their surfaces. The effectiveness of palpation, though, is ideally facilitated in an individual who has well-developed muscles and very little body fat. Learning Outcome: 12.1 Bloom's Taxonomy: 1-2: Remembering/Understanding 2) How can one determine whether or not the palmaris longus muscle is present in one's forearm? Answer: When the forearm is slightly flexed and the fist clenched, the tendon of the palmaris longus, if present, stands out as a ridge near the midline of the forearm along the distal third of the forearm. The tendon of the flexor carpi radialis also stands out under these conditions. If there is only one tendon present, it is that of the latter rather than the former, as the former is only present in approximately 85 percent of people. Learning Outcome: 12.1 Bloom's Taxonomy: 1-2: Remembering/Understanding 3) What is the femoral triangle and what is its clinical significance? Answer: The femoral triangle is the lower inguinal area, which is delineated by the sartorius muscle on the lateral side and by the adductor longus muscle on the medial side. Within this area is the site for palpation (and locating the pulse) of the femoral artery. It is also the site for accessing the cardiovascular system with a needle and catheter. Learning Outcome: 12.1 Bloom's Taxonomy: 3-4: Applying/Analyzing 4) How are the structures of the foot and leg affected by wearing high-heeled shoes or boots? What surface anatomical structures would you expect to change when a person puts on this type of footwear? Answer: In order to balance upon a high-heeled shoe, the foot must be plantar flexed. The muscles that contract to perform this action include the soleus and gastrocnemius; therefore, a student of surface anatomy would note that these muscles, which cover the posterior aspect of the calf, would bulge, and the tendon leading inferiorly from them, the calcaneal tendon, would be taut. When wearing footwear with a low heel height, the calf muscles show less tension. Learning Outcome: 12.1 Bloom's Taxonomy: 5-6: Evaluating/Creating

5) Why is it important to know the standards for viewing cross-sectional images? Answer: The point of view, or reference, in any anatomical image is the most important part of the image. If one does not know from which direction one is observing a cross-sectional region, it is impossible to accurately identify specific structures. Also, this same approach is used in viewing radiographic images around the world. Without standardization, medical errors are imminent.

Answer: TRUE Learning Outcome: 13.9 Bloom's Taxonomy: 1-2: Remembering/Understanding 13.3 Essay Questions 1) What is the significance of the blood-brain barrier in brain cell function? Answer: The blood-brain barrier acts to isolate the CNS neural tissue from the general circulation of blood because the hormones or other chemicals normally present in blood could have disruptive effects on neuron function. Learning Outcome: 13.3 Bloom's Taxonomy: 1-2: Remembering/Understanding 2) How do the functions of Schwann cells differ from those of satellite cells? Answer: Both satellite cells and Schwann cells are neuroglial cells. Schwann cells produce a complete covering around every peripheral axon, whether or not it is myelinated. As a result, all axons within the PNS are shielded from contact with interstitial fluids by the Schwann cells, which also participate in the repair process after neuronal injury. Satellite cells surround the nerve cell bodies in peripheral ganglia, but not the axons. Satellite cells regulate the exchange of oxygen, carbon dioxide, nutrients, and waste products between the neuron cell body and the extracellular fluid. They also help isolate the neuron from stimuli other than those provided at synapses. Additionally, they help regulate neurotransmitter levels around neurons in ganglia. Learning Outcome: 13.3 Bloom's Taxonomy: 3-4: Applying/Analyzing 3) What is Wallerian degeneration? Answer: The process of Wallerian degeneration occurs when the axon distal to the site of injury of a nerve deteriorates and macrophages migrate in to phagocytize the debris. The Schwann cells in the area then divide and form a solid cellular cord that follows the path of the original axon. If the neuron recovers, its axon will regrow into the site of the injury and the Schwann cells will wrap around it. Learning Outcome: 13.5 Bloom's Taxonomy: 1-2: Remembering/Understanding 4) What occurs at the axon terminals of a neuron during synaptic communication? Answer: At the axon terminal , the neuron communicates with another cell. The axon terminal occurs at the distal ends of the axon or collaterals of a neuron. Synaptic vesicles in the axon terminal store neurotransmitters, which are released through exocytosis at the presynaptic membrane in response to the arrival of an action potential at the axon terminal. The neurotransmitter diffuses across the synaptic cleft and binds to receptors on the postsynaptic membrane. Receptor binding results in a change in the permeability of the postsynaptic cell membrane. Depending on the identity and abundance of the receptor proteins on the postsynaptic membrane, the result may be excitatory or inhibitory.

5) What effect does a reverberating circuit have on the ability of the organism to function? Answer: Reverberating circuits utilize positive feedback that will allow a circuit to continue to be stimulated until either synaptic fatigue or an inhibitory stimulus breaks the cycle. Positive feedback occurs as a result of collateral axons, which extend back toward the source of the impulse that further excites the presynaptic neurons. Reverberating circuits using neuronal pools in the brain may be involved in the maintenance of consciousness, muscular coordination, and normal breathing patterns. Learning Outcome: 13.8 Bloom's Taxonomy: 5-6: Evaluating/Creating 6) What would be the consequences of severing the spinal cord from the brain? Answer: Dependent on the degree of damage, severing of the spinal cord at any level will result in the partial or complete loss of the ability for the ascending and descending pathways to transmit signals up and down the spinal cord. Severing of the spinal cord from the brain causes instant death due to the body's inability to function without the control provided by the brain.

Answer: Crural palsies involve the nerves of the lumbosacral plexus. Individuals who carry large wallets in their hip pockets may develop symptoms of sciatic compression after they drive or sit in one position for extended periods. As nerve function declines, the individuals notice symptoms, such as lumbar or gluteal pain, numbness along the back of the leg, and weakness in the leg muscles. Learning Outcome: 14.5 Bloom's Taxonomy: 3-4: Applying/Analyzing 2) Why are spinal taps done in the lumbar region when a CNS infection is suspected? Answer: In a spinal tap or lumbar puncture (LP), the withdrawal of cerebrospinal fluid (CSF) must be done with care to avoid injuring the spinal cord. The adult spinal cord extends only as far as vertebra L1 or L2. Between vertebra L2 and the sacrum, the meningeal layers remain intact, but they enclose only the relatively sturdy components of the cauda equina and a significant quantity of CSF. With the vertebral column flexed, a needle can be inserted between the lower lumbar vertebrae and into the subarachnoid space with minimal risk to the cauda equina. In this procedure, 3 to 9 ml of fluid are taken from the subarachnoid space between vertebrae L3 and L4. Learning Outcome: 14.5 Bloom's Taxonomy: 3-4: Applying/Analyzing 3) Why does a hammer striking the quadriceps muscle tendon result in a reflex action? Answer: The reflex action is known as the patellar reflex, which is controlled by muscle spindles in the quadriceps muscle group. The stimulus is a reflex hammer striking the muscle tendon, which stretches the spindle fibers. This results in a sudden increase in the activity of the sensory neurons, which synapse on spinal motor neurons. The response occurs upon the activation of motor units in the quadriceps group, which produces an immediate increase in muscle tone and a sudden contraction.

15.3 Essay Questions 1) Predict the effects of a superficial injury to the spinocerebellar tracts. Answer: The spinocerebellar tracts are responsible for carrying proprioceptive information concerning the position of muscles, tendons, and joints to the cerebellum. As a result of lacking some proprioceptive information, motor movement, especially complex movements, could become uncoordinated because the cerebellum is responsible for fine coordination of body movements (complex motor patterns). Additionally, there would be no conscious recognition of this lack of proprioception because the information does not reach the cerebral cortex. Learning Outcome: 15.2 Bloom's Taxonomy: 5-6: Evaluating/Creating 2) Ascending sensory information is relayed from one nucleus to another in a series of steps, which permits modulation of the response, but this processing takes time. Why is this delay in response not dangerous to the organism? Answer: Each additional synapse means another synaptic delay, but to compensate for this slowing of the response time, involuntary motor commands are issued by relay stations in the spinal cord and brain stem. While the conscious mind is still processing the information, neural reflexes provide an immediate response that can later be "fine-tuned."

Answer: Epidural hemorrhage is a condition in which bleeding into the epidural space of the brain occurs as a result of damage to the meningeal vessels. The most common cases of epidural bleeding involve an arterial break. In this case, the arterial blood pressure rapidly forces considerable quantities of blood into the epidural space, distorting the underlying soft tissues of the brain. The affected individual may lose consciousness from minutes to hours after a severe head injury, and death follows if left untreated. Epidural hemorrhage may also involve a damaged vein. In such cases, massive symptoms are not apparent immediately, and the individual may become unconscious from several hours to several days or even weeks after the original incident. Epidural hemorrhages are rare, occurring in less than one percent of head injuries. The term subdural hemorrhage is somewhat misleading because blood actually enters the inner layer of the dura mater, flowing beneath the epithelium that contacts the arachnoid membrane. Subdural hemorrhages are roughly twice as common as epidural hemorrhages. The most common source of blood is a small vein or one of the dural sinuses. Because the blood pressure is somewhat lower than in a typical epidural hemorrhage, the extent and effects of the condition may be quite variable. The hemorrhage produces a mass of clotted and partially clotted blood, called a hematoma. Acute subdural hematomas become symptomatic in minutes to hours after injury. Chronic subdural hematomas may produce symptoms weeks, months, or even years after a head injury. Learning Outcome: 16.2 Bloom's Taxonomy: 3-4: Applying/Analyzing 2) How does physical activity affect neuroplasticity? Answer: It has been theorized that physical activity can increase the (neuro) plasticity in the brain. The theory is exhibited in the observation of the adult hippocampus, which clearly demonstrates the addition of new neurons in an activity-dependent way. The stimuli that induce plasticity include both physical and cognitive activities. Research indicates that physical activity throughout life may be needed to provide the brain and its systems of plastic adaptation with the appropriate regulatory input and feedback.

3) What is cerebellar dysfunction? Answer: Cerebellar dysfunction is the condition in which an individual is unable to anticipate and stop a movement precisely. In this condition, the individual's cerebellar function is compromised as a result of cerebral palsy (brain injury before, during, or soon after birth), hereditary conditions, stroke, multiple sclerosis (causing cerebellar plaques), infections (meningitis), tumors, trauma, vitamin deficiencies, drugs, or toxins. Without the cerebellar ability to adjust movements while they are occurring, the individual becomes unable to anticipate the course of a movement over time. Most commonly, a reaching movement ends with the hand overshooting the target. Learning Outcome: 16.7 Bloom's Taxonomy: 3-4: Applying/Analyzing 4) Describe the condition known as infant hydrocephalus and its cause(s) and effect(s). Answer: Infant hydrocephalus is a condition in which an infant's skull exhibits abnormally high intracranial pressure, resulting in an enlarged cranium. Because the arachnoid granulations do not appear until roughly three years of age, infants are especially sensitive to alterations in intracranial pressure. Abnormally high intracranial pressure causes the ventricles to expand. Since the cranial sutures in an infant have yet to fuse, the skull can enlarge to accommodate the extra fluid volume. This enlargement produces the condition called hydrocephalus (or "water on the brain") in which the skull has expanded enormously, causing distortion of the brain. Infant hydrocephalus often results from interference with normal CSF circulation, such as blockage of the aqueduct of the midbrain or constriction of the connection between the subarachnoid spaces of the cranial and spinal meninges. Untreated infants often suffer some degree of mental developmental delay. Successful treatment usually involves the installation of a shunt, a tube that either bypasses the blockage site or drains the excess CSF. In either case, the goal is reduction of the elevated intracranial pressure. Learning Outcome: 16.8 Bloom's Taxonomy: 3-4: Applying/Analyzing 5) What is Bell's palsy? Answer: Bell's palsy results from an inflammation of the facial nerve that is probably related to viral infection. Involvement of the facial nerve (N VII) can be deduced from symptoms of paralysis of facial muscles on the affected side and loss of taste sensations from the anterior twothirds of the tongue. The individual does not show prominent sensory deficits, and the condition is usually painless. In most cases, Bell's palsy "cures itself" after a few weeks or months, but this process can be accelerated by early treatment with corticosteroids and antiviral drugs.

17.3 Essay Questions 1) A young woman has noticed that her hands and feet, when exposed to cold temperatures, become pale, then develop blue tones, and eventually become red in color. What is most likely the prognosis of her condition? Describe the disorder and its consequences. Answer: The young woman appears to be affected by Raynaud's syndrome, or primary Raynaud's phenomenon. In this condition, for unknown reasons, the sympathetic system temporarily orders excessive peripheral vasoconstriction of small arteries, usually in response to cold temperatures. The hands, feet, ears, and nose become deprived of their normal blood circulation; and the skin in these areas changes color, becoming initially pale and then developing blue tones. A red color ends the cycle as normal blood flow returns. The symptoms may spread to adjacent areas as the disorder progresses. Most cases do not cause tissue damage, although in rare cases, prolonged decreased blood flow may distort the skin and nails, even progressing to skin ulcers or the more extensive tissue death of dry gangrene. Learning Outcome: 17.2 Bloom's Taxonomy: 3-4: Applying/Analyzing 2) A patient has suffered a spinal cord injury, affecting spinal nerves L1 and L2. What sympathetic symptoms are affected? Answer: Since spinal nerves L1 and L2 possess sympathetic efferent fibers that innervate the detrusor muscle of the urinary bladder wall and the involuntary urethral sphincter, an injury to these nerves would block (fully or partially) the typical increased sympathetic nervous system activity, which inhibits contraction of the urinary bladder and stimulates contraction of the involuntary urethral sphincter. Therefore, the patient would fail to prevent the passage of urine out of the bladder. Learning Outcome: 17.4 Bloom's Taxonomy: 3-4: Applying/Analyzing 3) Compare and contrast the features of the CNS motor neurons, fibers, and degree of divergence from CNS to ganglion cells, and functions of the sympathetic and parasympathetic divisions of the ANS. Answer: Regarding the location of CNS visceral motor neurons, those in the sympathetic division are located in the lateral horns of spinal segments T1-L2, whereas those in the parasympathetic division are located in the brainstem and spinal segments S2-S4. In the sympathetic division, preganglionic fibers are relatively short and myelinated, whereas those in the parasympathetic division are relatively long and myelinated. Both types of preganglionic fibers release acetylcholine. Sympathetic postganglionic fibers are relatively long and unmyelinated, and usually release norepinephrine, whereas parasympathetic postganglionic fibers are relatively short, unmyelinated, and always release acetylcholine. Divergence from the CNS to sympathetic ganglion cells is approximately 1:32; whereas that in the parasympathetic division is approximately 1:6. Functionally, the sympathetic division stimulates metabolism, increases alertness, and prepares the individual for emergency "fight or flight" response. In the parasympathetic division, effects include promoting relaxation, nutrient uptake, and energy storage for the "rest and repose" response.

Answer: TRUE Learning Outcome: 18.6 Bloom's Taxonomy: 1-2: Remembering/Understanding 18.3 Essay Questions 1) What is referred pain? Answer: Pain sensations from visceral organs are carried by sensory nerves that reach the spinal cord with the dorsal roots of spinal nerves. Referred pain occurs when these visceral pain sensations are perceived as originating in more superficial regions of the body that are innervated by the same specific spinal nerves. For example, cardiac pain is often perceived as originating in the upper chest and left arm. Learning Outcome: 18.2 Bloom's Taxonomy: 3-4: Applying/Analyzing 2) How do tasting abilities change with age? Why do they change? Answer: At the beginning of life, an individual has more than 10,000 taste buds, and the number begins to decline dramatically by age 50. Concurrent with this sensory loss, an aging individual also experiences a decline in the population of olfactory receptors. As a result, many elderly people find that their food tastes bland and unappetizing, whereas children often find the same foods too spicy. Learning Outcome: 18.4 Bloom's Taxonomy: 3-4: Applying/Analyzing 3) What is acute otitis media? How does acute otitis media of bacterial origin differ from a case that is of viral origin? Answer: Acute otitis media is an infection of the middle ear, frequently of bacterial origin, which commonly occurs in infants and children and is occasionally seen in adults. During an upper respiratory infection, the middle ear, which is usually a sterile, air-filled cavity, becomes infected by bacterial pathogens that arrive via the auditory tube. In such cases, symptoms may worsen and the mucus becomes cloudy with the bacteria and active or dead neutrophils. If severe otitis media results, antibiotics must be promptly prescribed to treat the infection. If left untreated, pus accumulates in the middle car cavity, and the tympanic membrane becomes painfully distorted and may rupture. Infection of the adjacent mastoid bone may occur as well, spreading to the mastoid air cells, which may lead to a condition called chronic mastoiditis. This condition, accompanied by drainage through a perforated eardrum and scarring around the auditory ossicles, is a common cause of hearing loss in areas of the world without access to medical treatment. If caused by a virus, otitis media may resolve in a few days without the use of antibiotics. This "watchful waiting" is most appropriate where medical care is readily available. Instead of antibiotics, analgesics are administered to reduce the pain, and the use of decongestants helps drain the stagnant clear mucus produced in response to mucosal swelling.

4) Compare and contrast conductive deafness versus nerve deafness. Answer: Conductive deafness results from conditions in the middle ear that block the normal transfer of vibration from the tympanic membrane to the oval window. Common factors that could cause blockage of the external acoustic meatus include accumulated wax or trapped water. Factors that could cause more serious cases of conductive deafness may involve scarring or perforation of the tympanic membrane, fluid in the middle ear chamber, and immobilization of one or more of the auditory ossicles. In nerve deafness, the problem lies within the cochlea or somewhere along the auditory pathway. In this case, the sound vibrations are reaching the oval window, but either the receptors cannot respond or their response cannot reach its central destinations. Factors that could cause this type of deafness include certain drugs that may enter the endolymph and kill the auditory receptors, and infections that may damage the hair cells or affect the cochlear nerve. More specifically, exposure to high doses of aminoglycoside antibiotics, such as neomycin or gentamicin, can damage the hair cells in the cochlea. This potential side effect must be balanced against the severity of infection before these drugs are prescribed. Learning Outcome: 18.5 Bloom's Taxonomy: 3-4: Applying/Analyzing 5) What is glaucoma and what is its cause(s)? Answer: Glaucoma is the condition in which the aqueous humor no longer has free access to the canal of Schlemm. Although drainage is impaired, production of aqueous humor continues, and the intra-ocular pressure begins to rise. The fibrous scleral coat cannot expand significantly, so the increasing pressures begin to push against the surrounding intra-ocular soft tissues. When intra-ocular pressures have risen to roughly twice the normal levels, distortion of the nerve fibers begins to affect visual perception. If this condition is not corrected, blindness eventually results. Learning Outcome: 18.6 Bloom's Taxonomy: 3-4: Applying/Analyzing

Answer: TRUE Learning Outcome: 19.8 Bloom's Taxonomy: 1-2: Remembering/Understanding 19.3 Essay Questions 1) What is the hypophyseal portal system? Answer: The hypophyseal portal system is the network of vessels interconnecting the hypothalamus and anterior lobe of the pituitary gland. Near the attachment of the infundibulum, hypothalamic neurons release regulatory hormones into the surrounding interstitial fluids. These secretions diffuse into the primary capillary plexus and are delivered to the anterior lobe through vessels that form a secondary capillary plexus that surrounds the endocrine cells in that area. The vessels that interconnect these two capillary beds are called portal vessels. Together these constituents comprise the hypophyseal portal system. Learning Outcome: 19.2 Bloom's Taxonomy: 3-4: Applying/Analyzing 2) How do the parathyroid glands function in opposition to the thyroid glands? Answer: The thyroid gland's C thyrocyte cells secrete calcitonin, a hormone that targets the bones, kidneys, and intestines to decrease the calcium ion concentrations in the body fluids. The parathyroid gland's principal cells secrete parathyroid hormone, which targets the same organs as calcitonin does, but increases calcium ion concentrations. In homeostasis, the two hormones regulate calcium levels in the body. Learning Outcome: 19.4 Bloom's Taxonomy: 3-4: Applying/Analyzing 13 Copyright © 2018 Pearson Education, Inc.

3) How does the role of the thymus change as an infant grows? Answer: The thymus is much larger in infants and children than in adults. It produces hormones for the development and maintenance of normal immunological defenses, such as "thymosin" (actually a mixture of several hormones), which promotes the development and maturation of lymphocytes. Decrease in the size and secretory abilities of this gland as people age may render their immune systems less capable of preventing disease. Learning Outcome: 19.5 Bloom's Taxonomy: 3-4: Applying/Analyzing 4) What are the effects of the secretions of the adrenal medulla on the body? Answer: The adrenal medulla has two cell populations of endocrine cells: one secreting epinephrine (adrenaline), and the other norepinephrine (noradrenaline). The medulla secretes roughly three times as much epinephrine as norepinephrine. Their secretion triggers cellular energy utilization and the mobilization of energy reserves. This combination increases muscular strength and endurance. The metabolic changes that follow catecholamine release are at their peak 30 seconds after adrenal stimulation, and they linger for several minutes thereafter. As a result, the effects produced by stimulation of the adrenal medulla outlast the other signs of sympathetic activation. Learning Outcome: 19.6 Bloom's Taxonomy: 3-4: Applying/Analyzing

Answer: TRUE Learning Outcome: 20.3 Bloom's Taxonomy: 1-2: Remembering/Understanding 20.3 Essay Questions 1) Discuss the concept of "plasma expanders," often used for patients who are preparing for whole blood transfusions. Answer: Plasma expanders are solutions that can be used to increase blood volume temporarily, over a period of hours, while preparing for a transfusion of whole blood. They contain large carbohydrate molecules, rather than dissolved proteins, to maintain proper osmolarity. Although these carbohydrates are not metabolized, they are gradually removed from circulation by phagocytes, and the blood volume steadily declines. Plasma expanders are easily stored, and their sterile preparation ensures that there are no problems with viral or bacterial contamination. Although they provide a temporary solution to hypovolemia (low blood volume), plasma expanders fail to increase the amount of oxygen delivered to peripheral tissues. Learning Outcome: 20.2 Bloom's Taxonomy: 3-4: Applying/Analyzing 2) What factors contribute to the short (approximately 120-day) life span of an erythrocyte? Answer: As they differentiate and mature, erythrocytes lose most of their organelles, thereby forfeiting any mechanism for repair. Also, erythrocytes are exposed to severe stresses caused by making a complete circulatory circuit approximately every 30 seconds, participating in rouleaux, squeezing through small capillaries, and in general suffering much wear and tear from traveling 700 miles in 120 days. After this time they are phagocytized. Learning Outcome: 20.2 Bloom's Taxonomy: 3-4: Applying/Analyzing

3) A college student who is constantly dieting decides to go to the dining hall, as she has no energy, is experiencing muscular weakness, and sometimes becomes dizzy upon exertion. What is the likely diagnosis, and what is the cause of this condition? Answer: The student probably is anemic, partially caused by a diet that is low in protein and probably missing some essential amino acids. Anemia is caused by a reduction in the oxygencarrying capacity of the red blood cells, thus reducing the amount of oxygen that can reach the tissues. This resulting oxygen deficiency causes muscular weakness and fatigue, as well as a variety of other symptoms. Learning Outcome: 20.2 Bloom's Taxonomy: 3-4: Applying/Analyzing 4) If a person with type A blood receives a type B blood transfusion, what event(s) may occur? Answer: The plasma of type A blood contains anti-B antibodies, which will attack type B surface antigens. When an antibody meets its specific surface antigen, a cross-reaction occurs, resulting in agglutination (clumping) initially; and hemolysis may follow. Clumps and fragments of blood cells under attack form drifting masses that may plug small vessels, damaging or destroying tissues deprived of circulation.

21.3 Essay Questions 1) Describe the differences between carditis, endocarditis, and myocarditis? Answer: Carditis is a general term for inflammation of the heart. Clinical conditions resulting from cardiac infection are usually identified by the primary site of the infection. For example, infections that affect the endocardium produce symptoms of endocarditis, a condition that damages primarily the chordae tendineae and heart valves; the mortality rate may reach 21-35 percent. The destruction of heart valves by the infection may lead to valve leakage, heart failure, and death. Myocarditis, or inflammation of the heart muscle, can be caused by bacteria, viruses, protozoans, or fungal pathogens that either attack the myocardium directly or produce toxins that damage the myocardium. The most severe complications of myocarditis result from the formation of blood clots. These clots subsequently break free, entering the bloodstream as drifting emboli that may cause strokes, heart attacks, or kidney failure. Over time, abnormal contractions may appear and the heart muscle weakens; these problems may eventually prove fatal. Learning Outcome: 21.3 Bloom's Taxonomy: 3-4: Applying/Analyzing 2) If a woman is diagnosed as having a heart murmur, what anatomical condition does she have, and how does it affect heart function? Answer: Anatomically, a heart murmur occurs when the cusps of the left atrioventricular (mitral) valve do not close properly. The problem may be caused by abnormally long (or short) chordae tendineae or by defective papillary muscles. Because the valve does not work perfectly, some regurgitation may occur during left ventricular systole. The surges, swirls, and eddies that occur during regurgitation create a rushing, gurgling sound known as a heart murmur. In most cases, affected individuals are completely asymptomatic, and they live normal, healthy lives unaware of any circulatory malfunction. However, regurgitation may increase the risk of valve infection after some dental or medical procedures. Learning Outcome: 21.5 Bloom's Taxonomy: 3-4: Applying/Analyzing 3) What is angina and what is one of the least invasive surgical procedures used to relieve such a condition? Answer: Angina is one of the first symptoms of coronary artery disease (CAD). In the most common form of angina, temporary insufficiency of oxygen delivery and ischemia develop when the workload of the heart increases. Although the individual may feel comfortable at rest, any unusual exertion or emotional stress can produce a sensation of pressure, chest constriction, and pain that may radiate from the sternal area to the arms, back, and neck. Angina can often be controlled by a combination of drug treatment and changes in lifestyle, such as limiting strenuous activity and stressful situations, consuming a diet low in fat, and quitting smoking. Surgical treatment involves balloon angioplasty in which a catheter tip contains an inflatable balloon. Once in position, the balloon is inflated, compressing the plaque against the vessel walls. This procedure works best on small (under 10 mm), soft plaques. Because restenosis (or repeated narrowing) may develop, metal stents (or sleeves) can often be placed into the artery to hold it open.

4) What is the major surgical procedure used to treat obstructed regions in the coronary circulation of the heart? Answer: The procedure is called coronary artery bypass graft (CABG) surgery. It involves taking a small section from either a small artery (often the internal thoracic artery) or a superficial vein (such as the great saphenous) and implanting it in a region around the heart to create a detour (bypass) around the obstructed portion(s) of a coronary artery. As many as four of the coronary arteries can be rerouted this way in a single operation. The procedures are named according to the number of vessels repaired, so one speaks of single, double, triple, or quadruple CABG operations. Current recommendations are that CABG surgery should be reserved for cases of severe angina that do not respond to other treatments. Learning Outcome: 21.6 Bloom's Taxonomy: 3-4: Applying/Analyzing 5) A patient is admitted to the emergency room of a hospital complaining of chest pain and shortness of breath. Upon receiving the test results, it is determined that the individual is experiencing a myocardial infarction (MI). What anatomical changes occur during this condition, and what is/are the likely consequence(s)? Answer: In a myocardial infarction (MI), or heart attack, the coronary circulation becomes blocked and the cardiac muscle cells die from lack of oxygen. The affected tissue then degenerates, creating a nonfunctional area known as an infarct. Heart attacks most often result from severe coronary artery disease (CAD). The consequences depend on the site and nature of the circulatory blockage. If it occurs near the base of one of the coronary arteries, the damage will be widespread and the heart will probably stop beating. If the blockage involves one of the smaller arterial branches, the individual may survive the immediate crisis, but there are many potential, and unpleasant, complications. As scar tissue forms in the damaged area, the heartbeat may become irregular and less effective as a pump, and other vessels can become constricted creating additional cardiovascular problems such as angina. Learning Outcome: 21.9 Bloom's Taxonomy: 3-4: Applying/Analyzing 6) Describe cardiac arrhythmias and briefly discuss their different clinical classifications. Answer: Cardiac arrhythmias are abnormal cardiac rhythms, which range from inconsequential to lethal. If arrhythmias are occasional and brief in duration, they are rarely of any importance. However, if an arrhythmia persists, or occurs frequently, it merits medical attention. In clinical diagnosis, arrhythmias are classified as follows: (1) Alterations in heart rate, with normal nodal and conducting pathway function. These conditions, which usually indicate abnormal function at the SA node and atria, are often relatively harmless and may go undetected. Paroxysmal atrial tachycardia (PAT), premature atrial contraction (PAC), atrial flutter, and atrial fibrillation are clinical conditions of this classification. They are not considered very dangerous, unless they are prolonged or associated with some more serious indications of cardiac damage, such as CAD or valve problems. (2) Abnormal origination or distribution of the cardiac action potential within the ventricles. These conditions are dangerous and potentially lethal. Premature ventricular contractions (PVCs), ventricular tachycardia (VT or V-tach), and ventricular fibrillation (VF) are conditions that result in abnormal ventricular activity, which directly affects cardiac output. Many of these ventricular arrhythmias are potentially lethal. Learning Outcome: 21.9 Bloom's Taxonomy: 3-4: Applying/Analyzing 21 Copyright © 2018 Pearson Education, Inc.

Answer: TRUE Learning Outcome: 22.8 Bloom's Taxonomy: 1-2: Remembering/Understanding 22.3 Essay Questions 1) What mechanisms assist venous return to the heart? Answer: The blood pressure in venules and medium-sized veins is too low to oppose the force of gravity. As a result, blood can backflow, unless opposed by special mechanisms, such as oneway valves. In the limbs, veins of this size contain one-way valves that are formed from infoldings of the tunica intima. These valves act like the valves in the heart, preventing the backflow of blood. As long as the valves function normally, any movement that distorts or compresses a vein will push blood toward the heart. The valves act to compartmentalize the blood within the veins, dividing the weight of the blood between the compartments. Additionally, movement in the surrounding skeletal muscles in the region acts to squeeze the blood toward the heart, segment by segment. This mechanism is called a skeletal muscle pump. Learning Outcome: 22.1 Bloom's Taxonomy: 3-4: Applying/Analyzing 2) What is the role of the azygos vein and its tributaries in returning blood to the vena cava? Answer: The azygos vein is the major tributary of the superior vena cava (SVC). The other two vessels that are tributaries of the superior vena cava are the left and right brachiocephalic veins, which merge at the level of the first and second ribs to form the SVC. The azygos vein ascends from the lumbar region over the right side of the vertebral column to invade the thoracic cavity through the diaphragm. The azygos vein joins the SVC at the level of vertebra T2. On the left side, the azygos vein receives blood from the smaller hemi-azygos vein. The hemi-azygos vein may also drain into the highest intercostal vein, a tributary of the left brachiocephalic vein, by way of a small accessory hemi-azygos vein. Together, the azygos and hemi-azygos veins are the chief collecting vessels of the thorax. They receive blood from the intercostal veins (which receive blood from the chest muscles), the esophageal veins (which drain blood from the esophagus), and smaller veins draining other mediastinal structures.

3) What mechanism(s) and structures maintain the blood supply to the brain under various conditions? Answer: The brain has a dual blood supply. The internal carotid arteries normally supply the arteries of the anterior half of the cerebrum, and the rest of the brain receives blood from the vertebral arteries. But this circulatory pattern can easily change, because the internal carotid arteries and the basilar artery are interconnected in a ring-shaped anastomosis, called the cerebral arterial circle. This anastomosis encircles the infundibulum of the pituitary gland. With this arrangement, the brain can receive blood from either or both arterial sources, the carotid or the vertebral arteries, and the chances of a serious interruption of circulation are reduced. Learning Outcome: 22.5 Bloom's Taxonomy: 5-6: Evaluating/Creating 4) What is the pathway of blood into, through, and out of the hepatic portal system? Answer: The liver is the only digestive organ drained by the inferior vena cava (IVC). Blood leaving the capillary beds supplied by the celiac, superior mesenteric, and inferior mesenteric arteries flows into the veins of the hepatic portal system instead of traveling directly to the IVC. The hepatic portal system begins in the capillaries of the digestive organs and ends as the hepatic portal vein discharges blood into sinusoids in the liver. The tributaries of the hepatic portal vein include the following: 1) the inferior mesenteric vein collects blood from capillaries along the inferior portion of the large intestine; 2) the splenic vein is formed by the union of the inferior mesenteric vein and veins from the spleen, the lateral border of the stomach (left gastroepiploic vein), and the pancreas (pancreatic veins); and 3) the superior mesenteric vein collects blood from veins draining the stomach (right gastroepiploic vein), the small intestine (intestinal and pancreaticoduodenal veins), and two-thirds of the large intestine (ileocolic, right colic, and middle colic veins). The hepatic portal vein forms through the fusion of the superior mesenteric and splenic veins. Most of the nutrients and the greater volume of blood comes from the superior mesenteric artery. As it proceeds toward the liver, the hepatic portal vein also receives blood from the gastric veins, which drain the medial border of the stomach, and from the cystic veins from the gallbladder. In the portal triads at the periphery of liver lobules, the branches of the hepatic portal vein empty into liver sinusoids. As the blood flows through the sinusoids, nutrients are absorbed by hepatic cells before the blood reaches the central vein. Blood is eventually drained from the liver through hepatic veins into the inferior vena cava. Learning Outcome: 22.6 Bloom's Taxonomy: 3-4: Applying/Analyzing

23.3 Essay Questions 1) Discuss appendicitis and why appendectomies are sometimes necessary. Answer: Appendicitis generally follows an erosion of the epithelial lining of the vermiform appendix. Several factors may be responsible for the initial ulceration–notably, bacterial or viral pathogens. Bacteria that normally inhabit the lumen of the large intestine then cross the epithelium and enter the underlying tissues. Inflammation occurs, and the opening between the vermiform appendix and the rest of the intestinal tract may become constricted. Mucous secretion and pus formation accelerate, and the organ becomes increasingly distended. Eventually, the swollen and inflamed appendix may rupture, or perforate. If it does, bacteria will be released into the warm, dark, moist confines of the peritoneal space, where they can cause a life-threatening peritonitis. The most effective treatment for appendicitis is the surgical removal of the organ, a procedure known as an appendectomy. Learning Outcome: 23.5 Bloom's Taxonomy: 3-4: Applying/Analyzing 2) Paula's grandfather is diagnosed as having lung cancer. His physician orders biopsies of several lymph nodes from neighboring regions of the body, and Paula wonders why, since the cancer is in his lungs. What would you tell her? Answer: Lymphatics are found in most regions of the body, and lymphatic capillaries offer little resistance to the passage of cancer cells. As a result, metastasizing cancer cells often spread along that lymphatics. Under these circumstances, the lymph nodes serve as way stations for migrating cancer cells. Thus, an analysis of lymph nodes can provide information on the spread of the cancer cells, and such information has a direct influence on the selection of appropriate therapies. One example is the classification of breast cancer or lymphomas by the degree of lymph node involvement. Learning Outcome: 23.6 Bloom's Taxonomy: 5-6: Evaluating/Creating 3) How does the blood-thymus barrier function to prevent premature stimulation of developing T cells? Answer: The capillaries of the thymus resemble those of the CNS in that they do not permit free exchange between the interstitial fluid and the circulation. This lack of contact prevents antigens in the circulating blood from stimulating the developing T cells prior to their release into the circulation. Learning Outcome: 23.6 Bloom's Taxonomy: 1-2: Remembering/Understanding

4) When is a hematologic stem cell transplant utilized as a treatment option? What are the risks? Answer: A hematologic stem cell transplant, commonly known as a bone marrow transplant, is often a treatment option for acute, late-stage lymphoma. (Lymphomas are malignant tumors consisting of cancerous lymphocytes or lymphoid stem cells.) When suitable donor marrow stem cells are available, the patient receives whole-body irradiation, chemotherapy, or some combination of the two sufficient to kill tumor cells throughout the body. Unfortunately, this treatment also destroys normal bone marrow stem cells. Donor stem cells are then infused. Within two weeks, the donor cells colonize the bone marrow and begin producing new blood cells. Potential complications of stem cell transplantation include the risk of infection and bleeding while the donor marrow is becoming established. For a person with stage I or stage II lymphoma without bone marrow involvement, bone marrow can be removed and stored (frozen) for more than 10 years. If other treatment options fail or if the person comes out of remission at a later date, an autologous marrow transplant can be performed. Learning Outcome: 23.6 Bloom's Taxonomy: 3-4: Applying/Analyzing 5) What role does the lymphatic system play in metastatic cancer? Answer: Cancer that starts in the lymph nodes it is called lymphoma. More often, cancer starts somewhere else (primary tumor) and then spreads to lymph nodes. When cancer cells break away from the primary tumor, they travel through the bloodstream to the lymphatic system. Most of the escaped cancer cells die or are killed by NK cells before they can start growing. However, one or two might settle in new areas and begin to grow, forming metastatic tumors. Cancers that often spread through the bloodstream include hepatomas (primary liver tumors) and sarcomas (connective tissue tumor). Cancers that tend to metastasize through the lymphatic system include carcinomas (cancers derived from epithelial cells, chiefly glandular or squamous), such as breast and ovarian cancer, and melanomas (malignant tumors derived from melanin-forming cells). Eventually, all lymph ends up in the venous system, so cancers that start in the lymphatic system eventually travel through the blood.

24.3 Essay Questions 1) Discuss the symptoms and etiology of cystic fibrosis. Answer: Cystic fibrosis (CF) is the most common lethal inherited disease in the Caucasian population, occurring at a frequency of one instance for every 3000 births. The underlying problem involves an abnormality in a membrane transport protein responsible for the active transport of chloride ions. This membrane protein is abundant in exocrine cells that produce watery secretions. In people with CF, these cells cannot transport salts and water effectively, and the secretions produced are thick and gooey. Mucous glands of the respiratory tract and secretory cells of the pancreas, salivary glands, digestive tract, and reproductive tract are affected. The most serious symptoms appear because the respiratory defense system cannot transport such dense mucus. The mucus escalator stops working, and mucus plugs block the smaller respiratory passageways. This blockage reduces the diameter of the airways, and the inactivation of the normal respiratory defenses leads to frequent bacterial infections. The gene responsible for CF has been identified, and the structure of the membrane protein determined. Now that the structure of the gene is understood, research continues with the goal of correcting the defect by the insertion of normal genes. Learning Outcome: 24.1 Bloom's Taxonomy: 3-4: Applying/Analyzing 2) Why do children tend to have high-pitched voices; and why do males typically have lower voices than do females? Answer: Air passing through the glottis vibrates the vocal folds and produces sound waves. The entire larynx is involved in sound production because its walls vibrate, creating a composite sound. Amplification and echoing of the sound occur within the pharynx, the oral cavity, and the paranasal sinuses. The final production of distinct sounds depends on voluntary movements of the tongue, lips, and cheeks. The pitch of the sound produced by the larynx depends upon the length, diameter, and amount of tension in the vocal folds. The diameter and length of the vocal folds are directly related to the size of the larynx. The tension is controlled by the contraction of voluntary muscles that changes the relative positions of the thyroid and arytenoid cartilages. When the distance increases, the vocal folds tense and the pitch rises; when the distance decreases, the vocal folds relax and the pitch falls. Children have slender, short vocal folds; therefore, their voices tend to be high-pitched. At puberty, the larynx of a male enlarges considerably more than that of a female. The true vocal cords of an adult male are thicker and longer, and hence, they produce lower tones than those of an adult female. Learning Outcome: 24.3 Bloom's Taxonomy: 3-4: Applying/Analyzing

3) What happens when a person who is choking is treated using the Heimlich maneuver? Answer: Foreign objects, usually food, that become lodged in the larynx or trachea are usually expelled by coughing. If the individual can speak or make a sound, the airway is still open, and no emergency measures should be taken. On the other hand, if the individual can neither breathe nor speak, then an immediate threat to life exists. In the Heimlich maneuver (now called abdominal thrust), compression is applied to the abdomen immediately inferior to the diaphragm. Compression raises the diaphragm forcefully, which may generate enough pressure to expel the blockage rapidly. Once the item blocking the airway is removed, the person usually recovers quickly.

He is relieved to discover that he does not have cancer; but he has been diagnosed with emphysema. What anatomical changes occur in the lungs of a person with this condition? Answer: Emphysema is a chronic, progressive condition characterized by shortness of breath and an inability to tolerate physical exertion. This condition is often caused by exposure to either smoke or other environmental irritants over a long period of time. The underlying problem is the destruction of the respiratory exchange surfaces; more specifically, respiratory bronchioles and alveoli are functionally eliminated. The alveoli gradually expand and associated capillaries deteriorate, leaving large nonfunctional cavities in the lungs where gas exchange is severely decreased or eliminated. Unfortunately, the loss of alveoli and bronchioles in emphysema is irreversible. Further progression can be limited by the cessation of smoking. The only effective treatment for most severe cases is the administration of supplemental oxygen. Lung transplants and the surgical removal of non-functional lung tissue have helped some patients. Learning Outcome: 24.6 Bloom's Taxonomy: 3-4: Applying/Analyzing 5) Trace the pathway of inhaled air as it enters the vestibule of the nasal cavity to its final destination of entering the bloodstream in the lungs. Answer: Inhaled air enters the vestibule of the nose, swirls around the turbinate bones, enters the nasopharynx, oropharynx, and laryngopharynx; passes through the glottis in the larynx, and enters the trachea. Air then travels into the main bronchi, then the lobar bronchi, and then the segmental bronchi. The segmental bronchi deliver air to the bronchopulmonary segments of the lungs. Each segmental bronchus branches several times within the bronchopulmonary segment, ultimately giving rise to 6500 smaller terminal bronchioles. Each terminal bronchiole delivers air to a single pulmonary lobule within which the terminal bronchiole branches to form several respiratory bronchioles. Respiratory bronchioles are connected to individual alveoli and to multiple alveoli along regions called alveolar ducts. These passageways end at alveolar sacs, which are common chambers connected to several individual alveoli. An extensive network of capillaries is associated with each alveolus. Gas exchange occurs across the respiratory membrane, which are areas where the basal laminae of the alveolar epithelium and adjacent capillaries have fused.

6) Compare and contrast eupnea and hyperpnea. Answer: In eupnea, or quiet breathing, inspiration involves muscular contractions, but expiration is a passive process. During quiet breathing, expansion of the lungs stretches their elastic fibers. In addition, elevation of the rib cage stretches opposing skeletal muscles and elastic fibers in the connective tissues of the body wall. When the inspiratory muscles relax, these elastic structures contract which returns the diaphragm or rib cage or both to their original positions. Eupnea may involve diaphragmatic breathing (deep breathing) or costal breathing (shallow breathing). Hyperpnea, or forced breathing, involves active inspiratory and expiratory movements. Forced breathing calls upon the accessory muscles to assist with inspiration, and expiration involves contraction of the transversus thoracis and internal intercostal muscles. When a person is breathing at absolute maximum levels, such as during vigorous exercise, the abdominal muscles are used in exhalation. Their contraction compresses the abdominal contents, pushing them up against the diaphragm and further reducing the volume of the thoracic cavity.

25.3 Essay Questions 1) A woman who had a cesarean section several weeks previously was recovering well until she began to gain weight rapidly and had great distention of the abdominal cavity. Other symptoms include abdominal tenderness and soreness. From what condition is she likely suffering, and what is/are the cause(s)? Answer: It is likely that the woman has a condition called ascites (peritonitis) or an inflammation of the peritoneal lining of the abdominal cavity. The condition may have resulted from an infection she acquired during the surgery. The irritation of the peritoneum is the cause of all of the additional fluid secretion, and if the intra-abdominal pressure becomes too high, there may be damage to some organs, such as the kidneys, which are sensitive to increased abdominal pressures. Learning Outcome: 25.1 Bloom's Taxonomy: 5-6: Evaluating/Creating 2) An eight-year-old boy comes home from school feeling feverish and complaining of a sore and swollen throat and cheeks. What common childhood infection might he have contracted? If he must have this condition, why is it better for him to have it this year than ten or more years later and what other complications could exist? Answer: The little boy has likely contracted mumps, a viral infection that preferentially targets the salivary glands, most often the parotids; although, other organs may also become infected. The most common age for contracting mumps is between five and nine years of age. The first exposure stimulates antibody production and usually confers permanent immunity. Active immunity can be conferred by immunization. In post-adolescent males, the mumps virus may also infect the testes and cause sterility. Infection of the pancreas may produce temporary or permanent diabetes. Other organ systems, including the CNS, may be affected in severe cases. An effective mumps vaccine is available; hence, widespread distribution has almost eliminated this disease in the United States. Learning Outcome: 25.2 Bloom's Taxonomy: 5-6: Evaluating/Creating 3) A person has pain in the upper left quadrant of the abdominal cavity, and the symptom is detected within a few hours after eating, rather than in the middle of the night. What is the likely diagnosis? Answer: This condition might be indicative of a gastric ulcer, or, if less severe, gastritis, or irritation and inflammation of the gastric lining. A gastric ulcer occurs when the mucosal lining of the stomach is eroded away by excess hydrochloric acid. This irritation becomes most prominent when the stomach is empty, which begins to occur within a few hours of a large meal. Eating, or drinking a solution such as milk, which coats the gastric mucosa, may alleviate the symptoms. Learning Outcome: 25.5 Bloom's Taxonomy: 5-6: Evaluating/Creating

4) How do aggregated lymphoid nodules protect the small intestine from infection? Answer: Bacteria, especially E. coli, are normal inhabitants within the lumen of the large intestine. These bacteria are nourished by the surrounding mucosa. The epithelial barriers (cells, mucus, and digestive juices) and underlying cells of the lymphatic system protect the small intestine from bacteria migrating from the large intestine. Small, isolated, individual lymphoid nodules may be present in the lamina propria of the jejunum. In the ileum, the lymphoid nodules become more numerous, and they fuse together to form large masses of lymphatic tissue. These lymphoid centers, called aggregated lymphoid nodules, or Peyer's patches, may reach the size of cherries. They are most abundant in the terminal portion of the ileum, near the entrance to the large intestine, which normally contains large numbers of potentially harmful bacteria.

26.3 Essay Questions 1) If a patient has two damaged kidneys, what is the resulting condition? What are the treatment options? Answer: Typically, renal failure is the result when both kidneys are damaged. The condition of chronic renal failure can be managed if one restricts the intake of water and salt, and minimizes dietary protein. This combination reduces strain on the urinary system by minimizing the volume of urine produced and by preventing the generation of large quantities of nitrogenous wastes. If drugs and dietary controls cannot stabilize blood composition, more drastic measures, such as hemodialysis, are taken. In hemodialysis, a dialysis machine containing an artificial membrane is used to regulate the composition of blood. For temporary kidney dialysis, a silicone rubber tube called a shunt is inserted into a medium-sized artery and vein. While connected to the machine, the patient's blood circulates from the arterial shunt, through the machine, and back through the venous shunt. During this process, the blood flows past a selectively permeable artificial membrane, which contains pores large enough to permit the diffusion of small ions, but small enough to prevent the loss of plasma proteins. On the other side of the membrane flows a special dialysis fluid, facilitating potassium ions, phosphate ions, sulfate ions, urea, creatinine, and uric acid to diffuse across the membrane into the dialysis fluid. Conversely, bicarbonate ions and glucose diffuse into the bloodstream. In effect, diffusion across the dialysis membrane replaces normal glomerular filtration; thereby, changing the composition of the patient's blood. Additionally, the characteristics of the dialysis fluid can be modified for each patient to ensure that important metabolites remain in the bloodstream rather than diffusing across the membrane. An alternative to hemodialysis is peritoneal dialysis, which uses the peritoneal lining as a dialysis membrane. In this procedure, dialysis fluid is introduced into the peritoneum through a catheter in the abdominal wall, and the fluid is removed and replaced at intervals. One procedure involves cycling two liters of fluid in an hour: 15 minutes for infusion, 30 minutes for exchange, and 15 minutes for fluid reclamation. This procedure may be performed in a hospital or at home. In continuous ambulatory peritoneal dialysis (CAPD), patients self-administer two liters of dialysis fluid through the catheter and then continue normal activity until four to six hours later, when the fluid is replaced with fresh dialysis fluid. Ultimately, the most satisfactory solution for overall quality of life is kidney transplantation in which a new kidney obtained from a living donor or a cadaver is implanted into the patient.

2) What is/are the cause(s) of local blockages exist in the conducting system (collecting tubules, collecting ducts, or ureters)? What problems could develop from such blockages? Answer: Local blockages of the conducting system may result from the formation of small blood clots, epithelial cells, lipids, or other materials, collectively called casts. Casts are often excreted in the urine and are visible in microscopic analysis of urine samples. Calculi, or "kidney stones," form from calcium deposits, magnesium salts, or crystals of uric acid, resulting in a condition called nephrolithiasis. The urinary obstruction caused by kidney stones or other factors, such as external compression, is quite painful and is a serious problem because it reduces or eliminates filtration in the affected kidney. If peristalsis and fluid pressures cannot dislodge them, the stones must be surgically removed or destroyed. One nonsurgical alternative breaks kidney stones apart with a lithotripter, similar to the one used to destroy gallstones. Learning Outcome: 26.2 Bloom's Taxonomy: 5-6: Evaluating/Creating 3) Why are women more susceptible to contracting urinary tract infections (UTIs)? Answer: Urinary tract infections result from bacteria or fungi colonizing the urinary tract. The intestinal bacterium Escherichia coli is most often involved, and women are particularly susceptible to UTIs because of the close proximity of the external urethral orifice to the anus. Sexual intercourse may also push bacteria into the urethra and, since the female urethra is relatively short, toward the urinary bladder. The condition may be asymptomatic, but it can be detected by the presence of bacteria and blood cells in the urine. If inflammation of the urethral wall occurs, the condition is called urethritis, while inflammation of the lining of the urinary bladder represents cystitis. Many infections affect both regions to some degree. UTIs usually respond to antibiotic therapies. Learning Outcome: 26.2 Bloom's Taxonomy: 3-4: Applying/Analyzing 4) What is pyelitis? What is/are the cause(s) and consequences of this condition? Answer: Pyelitis is the inflammation of the walls of the renal pelvis. This condition typically results from untreated cases of UTIs wherein the bacteria proceeds along the ureters to the renal pelvis. If the bacteria invade the renal cortex and medulla as well, pyelonephritis results. Signs and symptoms of pyelonephritis include a high fever, intense pain on the affected side, vomiting, diarrhea, and the presence of blood cells and pus in the urine.

Answer: TRUE Learning Outcome: 27.3 Bloom's Taxonomy: 1-2: Remembering/Understanding 27.3 Essay Questions 1) What is the function of the scrotum? Answer: The scrotum positions the testes outside of the abdominal cavity, which is essential to normal development of spermatozoa, which require a temperature of 1.1 degrees C (2 degrees F) lower than the normal temperature within the abdominal cavity. The spermatic cord, which contains the nerves and blood supply to the testes, provides continuity with the rest of the body. The musculature of the scrotum is able to raise and lower the testes in response to temperature and other physiological changes. Learning Outcome: 27.2 Bloom's Taxonomy: 3-4: Applying/Analyzing 2) Briefly explain the process of spermatogenesis. Answer: Spermatogenesis is the process whereby sperm are produced. Spermatogenesis begins at the outermost layer of cells in the seminiferous tubules when stem cells called spermatogonia divide throughout adult life. One of the daughter cells remains as a stem cell; the other is pushed toward the lumen of the tubule. This cell differentiates into a primary spermatocyte that prepares to begin meiosis, the process of cell division that results in each cell having one-half the normal number of chromosomes, called haploid. Learning Outcome: 27.2 Bloom's Taxonomy: 5-6: Evaluating/Creating 3) Briefly explain the process of spermiogenesis. Answer: Spermiogenesis is the process whereby each spermatid matures into a single sperm cell. During this process, spermatids are embedded within the cytoplasm of large nurse cells attached to the tubular capsule and extend toward the lumen between the spermatocytes undergoing meiosis. During these processes, the spermatids gradually assume the appearance of mature spermatozoa. At spermiation, they lose attachment to the nurse cell and enter the lumen of the seminiferous tubule. The entire process takes approximately nine weeks. Learning Outcome: 27.2 Bloom's Taxonomy: 3-4: Applying/Analyzing

4) Describe the mechanism that permits the penis to become erect. Answer: A dense network of elastic fibers encircles the internal structure of the penis, surrounding three cylindrical columns of erectile tissue. This tissue is a three-dimensional maze of vascular channels incompletely separated by partitions of elastic connective tissue and smooth muscle fibers. At rest, the arterial branches are constricted and the muscular partitions are tense, reducing blood flow into the erectile tissue. Under parasympathetic stimulation the smooth muscle partitions relax, the vessels dilate, blood flow increases, the vascular channels become engorged with blood, and erection occurs. Learning Outcome: 27.2 Bloom's Taxonomy: 3-4: Applying/Analyzing 5) What are the most important events that occur in the uterine cycle? Answer: The uterine cycle averages 28 days in length and has three phases: the menses, the proliferative phase, and the secretory phase. The cycle begins with the onset of menses on day 1, continuing usually until day 5. At this time the functional zone of the endometrium is shed, in a process called menstruation. This process was triggered when the estrogen and progesterone levels fell at the end of the previous cycle. After the menses, under the influence of the circulating hormones, the epithelial cells of the endometrium multiply and spread across the surface. This will restore the functional zone, and coincides with the maturation of the egg prior to ovulation. When ovulation occurs, the functional zone is several millimeters thick and ready to receive the fertilized ovum. The secretory phase allows the endometrial glands to enlarge under the effects of the progestins and estrogens secreted by the corpus luteum. It continues until approximately 12 days after ovulation. Glandular activity then declines as the corpus luteum deteriorates, and the functional zone is eventually shed at the start of a new cycle. Learning Outcome: 27.3 Bloom's Taxonomy: 5-6: Evaluating/Creating 6) What processes are involved in the maturation of the ova? Answer: The stem cells, or oogonia, have completed their mitotic divisions prior to birth, at which time there are about 2,000,000 primordial oocytes. They remain in a suspended state until puberty, at which time there are approximately 4,000,000. Each of the primary oocytes is located in the outer cortex of the ovary in clusters called egg nests. They are surrounded by a layer of follicular cells and are known as primordial follicles. At puberty, FSH stimulation causes growth of the primordial follicles. The primordial follicles become primary follicles, in which the cells enlarge and undergo repeated divisions, making a layer of cells around the oocyte. These layers nourish the oocyte. Only a few primary follicles progress to secondary follicles, with thickened walls and an increased amount of follicular fluid. By days 8 to 10 in the cycle, a single secondary follicle is prepared to become a tertiary follicle, or mature ovarian follicle. It is this follicle that will ovulate on day 14.

28.3 Essay Questions 1) If a woman in the early stages of labor complains that she feels extreme pressure on her lower back, as if a bowling ball were pushing against her spine, and she is making little progress in dilation of the cervix, what might the problem be? Answer: The fetus is likely not to be in the normal, or vertex position, with the head engaged in the birth canal. In this case, the head is superiorly oriented, and pressing against the posterior aspect of the uterus. Unless the infant is able to be turned, this will be a breech presentation, or birth with the buttocks or legs first, rather than the head. Learning Outcome: 28.4 Bloom's Taxonomy: 3-4: Applying/Analyzing 2) What might be done to the mother to widen the opening of the birth canal? Answer: If the vaginal canal is too tight for the infant to pass easily through it within a short period of time, an incision, called an episiotomy, can be made at the edge of the vaginal opening at an angle toward the ischium, and away from the anal opening. In theory, this incision will prevent a tear of the perineum, which might cause damage to the anal opening. Learning Outcome: 28.4 Bloom's Taxonomy: 3-4: Applying/Analyzing 3) What are the potential effects of chromosomal abnormalities on the blastocyst? Answer: Abnormalities in chromosome number, shape, or form occur quite often. These abnormalities can occur during gamete formation, fertilization, or cleavage. If the chromosomal abnormalities are severe enough, they result in the spontaneous abortion (miscarriage) of the blastocyst or embryo. Many of these miscarriages occur early in pregnancy (within 2 to 3 weeks after fertilization), so a woman often spontaneously aborts without realizing she was ever pregnant. Some estimates indicate that about 50% of all pregnancies terminate as a result of spontaneous abortion; about half of these are caused by chromosomal abnormalities in the developing organism. As a consequence, fewer organisms are stillborn or born with severe birth defects. Thus, although 2-3% of all infants are born with some type of birth defect, this percentage would be much higher if not for the high frequency of spontaneous abortions very early in pregnancy.
