Research the major types of human joints and their functions, focusing on biomechanics and stability. Analyze ergonomic considerations in a specific occupation, identifying common joint injuries and preventive measures. Include a case study where joint health led to design changes in the workplace. Discuss emerging technologies related to joint health and their potential impact. Finally, reflect on your learning experience and the importance of joint health in performance

The articular system joins the different parts of the skeleton together and allows or restrains movement. Individual joints are described and classified by three qualities: the amount of movement permitted by the joint, the structure of the joint, and the location of the joint. Consider the role of joints within the human body and how they allow for movement in a particular way. How would changing the ankle joint from a hinge to a ball and socket affect the stability of the joint? How would it affect your ability to move the joint? Would you be able to walk or run? What impact would this have on the movements that you are able to do with your body? Pick 3 bones in the upper or lower extremities of the body and describe how they create movement. Use specific examples. Think about the ways in which skeletal muscles and bones work together to allow for movement in everyday activities as well as physical activities. In order to understand the effects of origin and insertion on joint movement, consider one or two of the major muscles or muscle groups and describe how the muscle originates proximally and inserts distally to cause a movement at the joints that are crossed. What types of movement does this create, and what are some actions that involve the use of these movements? Watch a YouTube member perform a movement such as skipping, doing sit-ups or crunches, touching their toes, picking up a book, or doing a triangle pose in yoga. Using your own words, describe the movement.

Discuss the relative value (to body homeostasis) of immovable, slightly movable, and freely movable joints.
There are three types of joints: synarthrotic, amphiarthrodial, and synovial. Identify and describe different exercises or activities that involve using each of these joints. Try to use examples that include more than one type of joint. Which bones and joints are primarily involved in each activity? Describe the type of joint(s) and their action(s). What types of joint movements are performed in each activity? Do you have any difficulty in performing the exercise or activity? How would you describe the problem, or lack thereof, in terms of joint health?
