Essay About The Brain

The Importance Of The Human Brain

The human brain is the direction for the nervous system. The brain tells the human what to do such as, it receives the input from the sensory organs, and then sends output to the muscles (Lewis, 2016). The human brain has responsibilities in the body just like the other organs, but has its own duties to maintain (Lewis, 2016). However, the humanbrain makes up 2 percent of the human body weight (Lewis, 2016). The cerebrum is the largest part of the human brain, and is branched into two different hemispheres (Lewis, 2016). Individuals also call the two the left and the right hemisphere. The brainstem is located underneath, and the cerebellum sits behind it (Lewis, 2016). The human brain is also divided into three different sections which is known as the forebrain, midbrain, and the hindbrain (Lewis, 2016). Each of the sections have something in common which is fluid–filled cavities called ventricles (Lewis, 2016). There are still more pathways in the future that need to be explored to clearly under the human brain.

Understanding the Human Brain There are still different pathways to be explored in our understanding of the human brain due to there is different studies that come as the years progress. One of the components that will still be open to the question is the several factors that affect the human brain that causes mental illnesses. The defining of the human brain is complication, and how the complication comes from the wide range of numerous factors that result in a

Subtopics About The Brain

Did you know that your brain weighs around 3 pounds and it's 2% of your body's weight? The brain is an organ that collects data. The brain is separated into halves into left and right hemispheres. It can collect data from sensory organs and nerve cells. In this essay, you'll learn about 3 subtopics about the brain: how does the brain work, what are the lobes of the brain, and what do the left and right hemispheres do?

There are many ways how the brain works. The main way is the brain collects data from sensory organs and nerve cells, but that's not all. The main structure of the brain is the cerebrum. There are two parts: the left hemisphere and the right hemisphere. Two structures called the thalamus and the hypothalamus deal with pain, hormones, and sleep. The hormones controls simple emotions. And the farthest structure from the center of the brain is the cerebral cortex, which it deals with big tasks, such as language, memory, thoughts, and emotions....show more content...

The 4 lobes are the Frontal Lobe, Parietal Lobe, Temporal Lobe, and Occiptal Lobe. These 4 lobes have jobs, but you'll learn first where they're located. The Frontal Lobe is located at the front of the brain. The Parietal Lobe is located at the top of the brain. The Temporal Lobe is located at both sides of the brain. And finally, the Occiptal Lobe is located at the back of the brain. Now, you'll learn about the jobs of the 4 lobes.The Frontal Lobe's job is on planning, reasoning, a part of speech, movement, and solving problems. The Temporal Lobe is specialized to hear and remember your memories. The Occiptal Lobe's shift is to sight things and vision. And The Parietal Lobe's work is on touching, pressure, temperature, and

Your brain is an organ that needs to be used in order to maintain its peak efficiency. Just like any other organ in the body, the brain will decline with age and lack of use. Similar to a computer, your brain is the command center for your entire body. The brain has over one hundred billion nerve cells that are interconnected to one another. Mentally stimulating yourbrain on a consistent basis will protect you from losing vital cognitive abilities. You should think of exercising your brain like physically exercising the rest of your body. Most age related memory loss is brought about by lack of mental activity and stimulation of the brain. The brain is continually growing new neurons so it is always possible to improve your brain function. There are various techniques that you can use to improve your brain function and prevent cognitive decline. You can improve your brain and improve your sense of alertness and well–being.

Physical Exercise: When you exercise you are actually helping your brain as well. Many people fail to make this connection. They may say that they feel better and happier after a workout. This is because exercise stimulates the nervous system. There have been many studies conducted showing how exercise before class helps students to be calmer and more focused in the classroom. Exercise stimulates serotonin which helps you to feel more peaceful. Many people will try to exercise in the morning before work in order to feel more alert and focused during

The Importance Of The Human Brain

The brain is such an amazing organ. The function of the brain is to receive information from other parts of the body, understand the information, and the figure out how to respond to the situation. The brain is responsible for such important things such as memory, body movements, the senses, and pretty much everything else. The average female brain weighs about 2.7lbs, and the average male brain weighs about 3lbs. The brain is also one of the fattest organs in the body. A little fun fact about the brain is that all of the blood vessels, located in just the brain, can stretch out to be 100,000 miles long. The human brain is the largest brain compared to all other living things around the same body size, and it makes up about 2% of the body weight.

The nervous system is an important part of the brain, and its purpose is to send messages to the brain. Which is divided into the central and peripheral systems. The central is composed of the brain. The peripheral is made of the spinal cord. There are three main part of the brain. The forebrain, midbrain, and hindbrain. The forebrain is located in the anterior part of the brain in the cerebral hemisphere. It consists of the thalamus, hypothalamus, and the subthalamus. (Britannica, encyclopedia britannica, 2017) The midbrain is located in the brain stem. It is responsible in aiding with vision, hearing, and motor control. (Britannica, Midbrain, 2017) Lastly, the hindbrain. The hindbrain consists of the medulla oblongata (breathing

Our brains have the enough power to make all of the many different parts of our body function the way it should. It can make our body do involuntary actions that constantly keep us alive and healthy, and we don't even realize all of the things that it is capable of. As Nicolaus Steno once said, "The brain, the masterpiece of creation, is almost unknown to us" (web.stanford.edu, 2014). The brain and its anatomy were first studied by the Egyptians in 1700 B.C., and ever since then, its immeasurable power has been continuously astonishing us with new and amazing discoveries of previously unknown capabilities (faculty.washington.edu, 2014). The first person to dissect the brain to study relationships between the brain and optic nerves was...show more content... And, since this experiment is about how hand eye dominance affects the hand eye coordination used when shooting a basketball, the occipital lobe is one of the most important parts of the brain in regards to this experiment. Everyone knows that the typical human being has a dominant hand.The only case in which a person does not have a dominant hand is if that person can use their right and left hand equally well. In this case this person is ambidextrous. But, the typical human also has a dominant foot, ear, side of the brain, and eye. (web.stanford.edu, 2014) Eye dominance, or eyedness, is the tendency to prefer visual input from one eye to the other. This is similar to left or righthandedness. For people who have anisometropic myopia, a different amount of nearsightedness in each eye, the eye with more myopia or nearsightedness is the dominant eye (web.stanford.edu, 2014). The easiest way to test your eyedness is to create a small triangle with your hands, with your thumbs as the base of the triangle and your left hand's fingers overlapping your right hand's fingers , and center it around an object, such as a doorknob, about 5–10 feet away with both eyes open. Then, close your left eye. If you can still see the object with your right eye opened, then your right eye is your dominant eye. If the object moves out of your view, then close your right eye. You will most likely see the object with your left eye, in which case your dominant eye is your left eye Get

Questions about the human brain have been a topic that many scientists and philosophers have focused on for centuries, trying to understand and learn the way it truly works . Over these past ten years, scientists have been the most successful in brain development, due to a large amount of research on this fascinating subject. Different ways to keep the brain stimulated have been an important topic while learning about the brain over the years due to its large importance. The human brain needs to be worked everyday in order for it to maintain a healthy state. Every time a new piece of information is taken in, different areas of your brain are put to use. It has been found that the more often stimulation of the brain occurs it enables the brain to be able to perform better on a daily basis and for longer periods of time....show more content... This is expected because chewing gum is suspicioned to be an accurate way to stimulate the brain which helps students increase intellectual performance by their ability to concentrate at a faster rate. Chewing gum causes stimulation of the brain because it improves blood flows, increasing arousal towards the brain ultimately innervating the jaw. The innervation begins with the repetitive chewing motion caused by the gum, which triggers the trigeminal nerve that works the jaw muscles and lets blood flow to the brain supplying it with nutrients, improving its functions. It's important to recognize certain controls throughout this experiment such as gender, gum flavour, and environment. None of the mentioned factors may have changed

Advantages And Disadvantages Of The Brain

Long ago, to understand the brain, its structural features and functions the only time this was possible were through a post mortem examination. Due to technological advances, this has become easier through various brain imagining techniques; the Magnetic Resonance Imaging (MRI) and the Positron Emission Tomography (PET). Thus, for the purpose of this essay, these two methods will be discussed as well as their advantages and disadvantages.

The brain is a portion of the central nervous system, which functions as a primary receiver, organizer, and distributor of information for the body (www.medicinenet.com). The first method to be discussed is the Magnetic Resonance Imagining. It uses a large magnet, radio waves, and a computer to create a detailed cross–sectional image of the patient's internal organs and...show more content...

The cognitive functions are distributed across the hemispheres but there are specific processes that are specialized to one hemisphere. Localization function which is on the left is known for its dominancy for language (www.indiana.edu). This concept traces back to faculty psychology, which was developed by Franz Gall and stated that different abilities such as reading were independent and autonomous function carried out in certain parts of the brain. Phrenology was developed as a way of further understanding the brain and this is the belief that certain mental faculties and character traits are indicated by the size of the skull (Galotti, 2008).

Broca discussed that injury to the left frontal lobe can cause inability to produce many words or speak fluently. This is known as Aphasia; disruption of expressive language. A second language centre was found which focuses on the control of language understanding rather than language production. This is located in the posterior region of the temporal lobe. Injury to this region of the brain can lead to an individual speaking gibberish (Galotti,

Abstract Drugs some use them to escape pain, others use them for pleasure, and some use them to just fit in. Either way drugs are a harmful substance that may seriously affect the body. Drugs mess with the brain in ways that we couldn't even imagine. From destroying brain cells that help with critical thinking to destroying cells that give us the ability to feel pleasure. Drugs take the place of our natural body functions of the body. They fool receptors of the body and make it to where our bodies produce less of what we need. Over a period of time this may produce very severe consequences on the body. With all the risks involved with drugs it's a wonder why some people use them.

In addition, the limbic system is responsible for our perception of other emotions, both positive and negative, which explains the mood altering properties of many drugs. The cerebral cortex is divided into areas that control specific functions. Different areas process information from our senses, enabling us to see, feel, hear, and taste. The front part of the cortex, the frontal cortex or forebrain, is the thinking center of the brain, it powers our ability to think, plan, solve problems, and make decisions.

How drugs work in the brain Drugs are chemicals they work in the brain by tapping into the brain's communication system and interfering with the way nerve cells normally send, receive, and process information. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter. This fools receptors and allows the drugs to lock onto and activate the nerve cells. Although these drugs mimic brain chemicals, they don't activate nerve cells in the same way as a natural neurotransmitter, and they lead to abnormal messages being transmitted through the network. Other drugs, such as amphetamine or cocaine, can cause the nerve cells to release abnormally large amounts of natural neurotransmitters or prevent the normal recycling of these brain chemicals. This disruption produces Get

Human Brain

The human being is considered to be the ultimate form of life on the earth. This is not because the human body is strong and agile. Many other animals posses skills much superior to humans and are able to perform feats humans can only dream of. The one thing that distinguishes humans from all of the other organisms on this planet is the brain. The brain is the site that controls the human body. However, unlike in animals, in man, the brain is also the site of the mind. The mind gives humans superiority over other creatures. It provides humans with the ability to reason, to feel and to adapt. Because of this, man has achieved so much, and has also realized that much more is still ahead.

This increase in knowledge is partly due to the recent advances in nuclear medicine. Although X–ray machines have been the chief mechanical tools for internal observations of the human body since Wilhelm Roentgen discovered X–rays in 1901, the development of computers made it possible for better and more accurate techniques to be applied to scan the human body. These methods employ various scanners like the CAT, PET, MRI and SPECT.

The CAT is an acronym for Computerized Axial Tomography. This method of scanning generally involves X–rays and enables scientists to view the inside of the head in a three dimensional format on a computer screen. PET stands for Positron Emission Tomography and it is much more complicated than the CAT scan. PET machines bombard the subject with doses of positrons the anti–matter equivalents of the electrons. As the positrons enter the body, they encounter electrons which are escaping from radioactive elements which have been injected into the bloodstream. When the positrons and the electrons collide, they give off energy which is recorded by a computer. The result is a far more detailed 3–D picture of the brain than the one obtained from the CAT machine. To obtain an even better image, physicians use the MRI, which stands for Magnetic Resonance Spectroscopy. With these three

The area that controls language (forebrain) shows most development in infancy and early childhood, when children are starting to gain more and more language (Krause,2010).In my years of working as a child care worker I have observed that, some children of the same age seemed to arrive at different developmental stages at different times. For example one child aged twelve months , could walk and move around obstacles with ease, her language was average for a child of her age ,yet another child of the same age was only able to sit on her bottom, did not attempt to walk or even crawl, but her language was outstanding. The brain is such a complex organ, I have learned the basic structure of the brain, and am able to better understand why some children in childcare were able to do things, others could not. It seems childhood is a crucial time for children and brain development, even though genetics play a great part in the way our brain is structured, a healthy diet, plenty of sleep and a good variety of experiences all play a part in the way our brain develops from early childhood (Krauss, 2010). There are two main Psychological theories of learning I would like to discuss, the first being Vygotsky's (social constructivism), the second Piaget's (personal constructivism) theories .Constructivists learning theories basically centre on the believe that the student is an active learner and has to build on his/her own learning.

"The Human Brain", by myPerspectives, is an informative article that claims that the brain is a complex organ that is truly impressive. The brain is a key part of the central nervous system, that controls the entire body's activities, to simple things such as breathing. These actions are fired through neurons, that quickly travel through the spinal cord. Surprisingly, thebrain transmits these messages at an unimaginable rate, at 150 miles per hour, through 85 billion cells, called neurons. These neurons can form up to 10,000 synapses, or connections to each other. By itself, the brain can create billions of synapses, which change the structure of the brain every time new information is learned. However, there is still much that scientists Get

The Structure Of The Brain Essay

Structure of the brain

The brain is made up of 4 main parts and they are:

в Џthe cerebral cortex,

в Џlimbic system,

в Џthe cerebellum

в Џand the brain stem

The cerebral cortex

The cerebral cortex is split into two cerebral hemispheres (the left and right hemispheres). Sometimes the right hemisphere is related to creativity and the left hemisphere is related to logic abilities. It is divided into four sections called lobes, the frontal lobe, parietal lobe, occipital lobe, and temporal lobe. This is the largest part of thebrain. The cerebral cortex is associated with determining intelligence, influencing your personality, motor function, planning and organization, processing sensory information and language processing. The cerebral cortex has sensory as well as motor areas therefore it is responsible for processing sensory information and motor functionality responses.

The frontal Lobe

The frontal lobe is the biggest lobe. It is involved in motor functions. The frontal lobe helps us to make decisions as well as assisting to solve problems. It is also connected language and speech functions. The frontal lobe is located at the front of that brain. It is also the biggest lobe in the brain. The frontal lobe is the part of the brain that controls important intellectual skills, such as emotional expression, memory and judgment.

Parietal Lobe

The parietal lobe is behind the frontal lobe and above the temporal lobe. It is responsible for receiving and processing sensory information and

In this paper one will learn the different parts of the brain and their functions. Although the brain isn't the largest organ of the human body it is the most complex and controlling organ. It is amazing how complicated the brain is. The brain controls every action within and out of your body. The brain has main areas that contain different areas that have specific functions. For instance the basal ganglia holds the lentiform and the caudate. The brain isn't just "THE BRAIN" it is actually a group of many parts. They help to inform the brain on the things going on with the human body. The brain is split in to two main parts, the left and the right hemisphere. The left hemisphere has about the same areas as the right hemisphere. The only...show more content...

The corpus callosum is a bundle of nerves that connects the two hemispheres. The area that passes and processes information concerning touch, pain, temperature, and pressure on skin is the thalamus. The limbic system controls your behavior and emotions. It is involved in emotions such as fear, rage, pleasure, and sorrow. In the prefrontal area of the frontal lobe emotional traits are controlled. In the temporal lobe expressed behavior is controlled. The parietal lobe discriminates sensory. The occipital lobe is where visual interpretation takes place. Pons is a crossroad for nerves going up to the cortex, to the cerebellum and then down the spinal cord. The cortex is the outer gray area where thinking takes place. The olfactory cortex receives senses from the nose that it then sorts out. The area that identifies what we see by working out movements, colors, and shapes is the visual cortex. The area that receives taste senses is called gustatory cortex. The area responsible for analyzing data, performing memory functions, learning new information, forming thoughts, and making decisions is the cerebral cortex. The motor cortex is involved in muscle movement. The cerebellum is vital when carrying out complicated, skilled movements. It is much like a mini brain. If before you read this paper you thought the brain was a "one man machine" I'm sure your opinion has changed after reading his paper. It is amazing how god has created the brain to have so many areas

The brain is made up of millions upon millions of cells. These cells are formed from before birth, up until about 7 years old. Once these brain cells stop dividing, they are never meant to divide again. You can see that the division of brain cells is under strict regulation and control. When this control is lost in a single cell, then it starts dividing in an uncontrolled manner. All of the data obtained through research on cancer shows that this disease is caused by a rapidly dividing cell, with no regulators to stop it from dividing. As the cell makes more and more copies of itself, it grows to form a tumor. This is known as cancer.

When a tumor is developed on the brain, it is called a brain tumor or brain cancer. Brain tumors can be...show more content...

Heredity also plays a role in the development of cancer. If a person's relatives have a history of cancer, then that person has a higher risk of developing cancer. Genetic variations, particularly those influencing how the body responds to carcinogens, may create a greater vulnerability to cancer.

Brain cancer is usually accompanied at first by headaches and seizures. Later symptoms could include nausea, vomiting, fever, change in pulse, and trouble breathing. Other mental changes may also occur such as difficulty in communication. Symptoms greatly depend on the location of the tumor. For example, if the tumor were located on the part of the brain controlling vision, then vision would be affected.

Once a person has been diagnosed with brain cancer, treatment should begin immediately. Treatment forbrain tumors involves any combination of surgery, radiation, and chemotherapy. Some tumors require several different surgical procedures; some can be treated with radiation alone. Surgery is the best process to remove a brain tumor. Surgery attempts to remove most, if not all of the tumor. Once most of the tumor is removed, the rest of the tumor can be removed through a process called radiotherapy.

Radiotherapy, also called radiation therapy, is the treatment of cancer and other diseases with radiation. Radiotherapy is used when the entire primary tumor cannot be surgically removed. Radiotherapy deposits energy

Current research shows that mental events cause physical events, and scientists believe examining single nerves is the key to understanding how the brain works as a complete unit. Understanding the brain at the nerve cell level will allow scientists to understand how human consciousness works (Blakeslee, 1992). Furthermore, the brain's thalamus is identified as the possible sensory connector because it fires 40 impulses per second that sweep through the entire brain (Blakeslee, 1995a). These findings are a serious implication to Dualism because it states the mind is not physical. If the mind is not physical, it cannot affect the physical body, so the Dualist theory of two–sided interactions between the body and mind are false. The...show more content...

Linking the mind to the brain would invalidate Searle's (1980) explanation that artificial intelligence is impossible because the brain is irrelevant when the mind is concerned. In other words, programs require machines to run, but the mind is independent of the brain. Recent findings suggest that the brain is directly linked to the mind, so even creating AI machines will be possible in the future because the mind is obviously linked to the body through the brain and the nervous system. Although new theories on human consciousness will obviously assist AI engineers, those theories will question the reliability of Dualism because they suggest that mind is a material substance that takes a certain space and creates certain manifestations in the body. In reality, it is possible that the mind is a material substance. For example, the human eye cannot observe atoms, but they are physical substances, so there is no reason to define mind as an immaterial substance based on the fact that it cannot be perceived. Even though the mind is invisible to the human senses, it is possible to observe the mind. Armstrong's (1980) proposal is that the consciousness is the observer of the current state of mind. While the human mind is automatically aware of its perceptions in the brain, a person's consciousness is aware of the mind's awareness of those perceptions (Armstrong, 1980). However, Armstrong's theory has two implications for Dualism. While Dualism defines mind as a

Left vs. Right Brain

The idea that the left and right sides of the brain can control many different aspects of behavior in different categories is an interesting one. Four websites which consider this concept are Neuro Pearls, the American Speech–Language–Hearing Association website, Left vs. RightBrain Modes, and SPLITTING THE HUMAN BRAIN.

In Left Vs. Right Brain Modes, a direct comparison is presented in several categories. The left hemisphere is described as verbal, analytical, logical. The right hemisphere is nonverbal (responding to touch and music), intuitive, and sensory. In some ways the descriptions fit with the "left– handed artist" stereotype, such as the left hemisphere being factual, and the right brain responsive to...show more content... The presence of the language function in either hemisphere can be determined using the Wada test, in which a barbiturate is injected into an internal carotid artery and the effects upon language are observed.

It is still unknown why handedness and language dominance are related in the brain, or why language is not bilateral.

The American Speech–Language–Hearing Association (ASHA)s website contains the article "Language: Left Brain? Right Brain? Both?" which describes the history of discovering the two hemispheres have different duties to the body, especially in terms of handedness and speech. Damage to the left side of the brain in most of Dr. Marc Dax's patients caused a loss of speech (1836). After his death, many more similar reports were recorded.

Much later, the right hemisphere was found to control essential functions as well. Since the effects of right hemisphere damage are more subtle, as seen in the first website, this conclusion took much longer to reach. For example, a loss of speech would not be apparent, but instead irrelevant and rambling speech would be observed.

It is concluded from this site that both hemispheres are needed for a normal use of language, and to categorize the two hemispheres (as was done

in the first website) would be gross oversimplification.

Essay about Addiction and the Brain

Addiction and the Brain

The ponderance that Brain = Behavior and the inherent ramifications of such proves no more fascinating than when addressed in the context of "Addiction and the Brain". Essential to consider is:

–what exactly is an addictive/abusive substance (drugs of abuse)

–what brain center(s)/chemical(s)are involved

–what does it mean to become physiologically dependent

–how should the concept of addiction be addressed

–how might we use animal models

–and what sort of treatment approaches should be pursued.

All drugs of abuse seem to activate DArelease from these two areas although each drug family tends to work via drastically different psychopharmacological mechanisms.

Besides the obvious appeal of the "high" or elation, which occurs subsequent to drug administration, a greater influence leading to an increased

dosage and necessitated use, would seem the acquisition of tolerance. There are three subtypes, pharmacokinetic/dispositional tolerance, pharmacodynamic tolerance, and behavioral tolerance which all prove relevant in the drugs of abuse, with the exception of the stimulants (cocaine, methylphenidate, etc). Pharmacokinetic tolerance refers to the changes in substance distribution due to the bodies metabolism of the drug, while pharmacodynamic tolerance addresses the adaptive changes which have taken place within the system thereby reducing the efficacy of the drug. The final, behavioral tolerance, seems perhaps at once the most confusing and most compelling. Behavioral tolerance has to do with the learned tolerance in relation to a specific situation and it's environmental cues by which the body adapts and prepares itself thus minimizing the drugs effect ( 6). Thus the physiological dependence, or the need to administer the drug in order to maintain even a state of normalcy, is a direct result of these developed tolerances. It is the re–setting of the bodies homeostatic mechanisms in order to adapt for the effect of

1.Biological psychology, of biopsychology, is the application of the principles of biology to the study of mental processes in terms of bodily mechanisms. The view that psychological processes have biological (or physiological) correlates, is the basic assumption of the whole field of biological psychology. Biologicalpsychology is a hopeful domain, one that has much to offer in terms of improving the quality of life of the healthy as well as those suffering from disorders. It also contributed important therapeutic data on a variety of conditions, including: Parkinson 's Disease, Alzheimer 's Disease, Clinical depression, Schizophrenia and a lot others. Humans have very complex nervous system, they use neurons and neurotransmitters to make the highest active communication network throughout the body. "most of the body's neurons are found in the central nervous system(CNS), which consists of the brain and spinal cord" (psychology 5th edition). "Neuroscience emphasizes that the brain and nervous system are central to understanding behavior, thought, and emotion. (Van Horn, 2014; Zhao & others, 2014). Therefore, for biological psychologist all that is psychological is first physiological. All thoughts, feeling & behavior ultimately have a biological cause." We are benefited from biological approach for diagnosing and treating human brains Ex. Schizophrenia. Scientists are also able to create medications for different types of illnesses. Besides having psychologists

The Cerebellum is located at the back of the brain , under the occipital and temporal lobes of the cereral cortex . and contains about 50% of the neurons in the brain and has been nicknamed the motor structure of the brain, due to the fact that a damaged cerebellum affects motor control and posture .The cerebellum performs the following functions

Maintains Balance and Posture

Coordination of voluntary movement

Motor Learning

Cognitive functions

The Cerebellum is built from four different types of neurons which include granule cells, Purkinje cells and two types of inhibitory interneurons (Golgi cells and basket cells)

The Brain Stem is on the bottom of the brain and is between the deeply rooted structures of the cerebral hemisphere and the cervical spinal cord. It is split into three sections or departments , midbrain(mesencephalon), pons(metencephalon and medulla oblongata 9myelencephalon). The brainstem which is storage for many control houses of the body that include functions like swallowing, breathing and vasomotor control. Cranial nerve nuclei is located in the brainstem with the exception of the ones associated with the olfaction and vision, these provide motor and sensory functions to the different structures in the cranium, e.g. facial muscles, tongue ,larynx and pharynx , it also serves the purpose of supplying the senses of taste, equilibrium and hearing .

Define Drug Addiction

For some people, the use of alcohol and drugs can lead to a chronic disease or long–term illness that has serious medical and social consequences. Are you feeling down, left out, trying to fit in? Addiction begins so easily and takes over without any warning. It can begin with a bad day, consequences, peer pressure, or a teen trying to find a way to fit in. "An estimated 2.4 million Americans used prescription drugs non–medically for the first time within the past year, which averages to approximately 6,600 initiates per day", states According to, the Centers for Disease Control and Prevention, "In 2014, 47,055 people died from drug overdoses. Since 2000, opioid drug overdoses have jumped 200%". While some people believe drug addiction is a choice, it is a disease. Continued drug use changes the brain 's structure and how the brain functions. Also, Environmental cues is why some people get addicted. Furthermore, drug addiction, like other diseases, may require medication to treat. Drug addiction is a disease that affects every aspect of one's life and Is a serious health issue. It begins with one–time use, which leads to full dependency. The symptoms of being addicted is loss of control, cravings, physical dependence, and tolerance. You can tell the difference between drug abuse and addiction. Addiction is when one loses the ability to willingly stop using drugs. When one is addicted to drugs the only thing they care about is how they are going to get their next fix. They
