P‌‍‍‍‌‍‍‌‌‍‍‍‌‍‍‍‍‌‍‍rior to beginning work on this assignment, review the following from your course text: Chapter 2: Skeletal System Chapter 3: Articular System Chapter 5: Muscular System Chapter 6: Nervous System For this assignment, you will explore the structure, features, and functions of the skeletal, articular, muscular, and nervous systems. Your paper must include an introduction, body, and a conclusion, and it must address the following elements: Skeletal System: Describe the five different types of bones. Select two examples for each type of bone. Discuss the general location of the chosen bones (e.g., head, thorax, trunk, etc.). Articular System: Examine the joint structures associated with the synovial joints. Identify three joint structures of your choice and explain their importance and function. Muscular System: Summarize the three types of muscle contractions. Explain the differences between concentric and eccentric contractions. Discuss two movements for each contraction. Nervous System: Discuss the main functions and components of the central nervous system (CNS). Discuss the main functions and components of the peripheral nervous system (PNS). Pathology Affecting All Four Systems: ‌‍‍‍‌‍‍‌‌‍‍‍‌‍‍‍‍‌‍‍ Select one pathology or condition of your choice. Explain how each of the four systems is affected. Note: The pathology or condition can cause the dysfunction or the dysfunction can cause a pathology or condition. Example A: A broken femur (skeletal system) will also impact our muscular and articular systems during the recovery process, while intense pain and other emotional effects are common (nervous system). Example B: When a person’s pancreas does not produce sufficient insulin (., type 1 diabetes), that person is at a higher risk for bone and joint disorders, muscle weakness, and nerve damage. Your The Four Systems assignment, Must be three double-spaced pages in length (not including title and references pages) and formatted according to APA Style (Links to an external site.) as outlined in the Writing Center. Must include a separate title slide with the following: Title of the Assignment Student’s name Course name and number Instructor’s name Date submitted Must use your course text and at least two additional scholarly or credible sources.
