Joints c. Muscles d. Tendons ANS: B
Joints are the functional units of the musculoskeletal system because they permit the mobility needed to perform the activities of daily living. The skeleton (bones) is the framework of the body. There are three types of muscles: skeletal, smooth, and cardiac and they produce movement when they contract. Tendons are strong fibrous cords that attach skeletal muscles to the bones. The other options are not correct. DIF: Cognitive Level: Understanding (Comprehension) MSC: Client Needs: Health Promotion and Maintenance
