If you have a major injury to an appendage you may want to stop the bleeding by tying a tourniquet. Tourniquets are belt-like apparatuses that need to be applied at least 2 inches above the injury, but not on a joint. Knowing this information indicate over which blood vessel(s) you would apply the tourniquet if someone received a deep cut: In the middle of their femoral region?

Often a stroke (cerebrovascular accident, CA), impairs one side of the body, resulting in paralysis (hemiplegia). The paralysis can range in severity. In more severe cases, the patient often loses most of the function of their upper extremity and presents with glenohumeral (i.e., shoulder) subluxation (an incomplete or partial dislocation of a joint). a. Why is the primary reason this happens? b. What is likely to happen if left unaddressed?

A 22-year-old woman injures her right knee while playing soccer. With the knee flexed 90 degrees, the physician grasps the leg just below the knee and pulls theTibia toward him.

Watch this animation (http://openstaxcollege.org/l/hipreplace) to observe hip replacement surgery (total hip arthroplasty), which can be used to alleviate the pain and loss of joint mobility associated with osteoarthritis of the hip joint. What is the most common cause of hip disability?

Compare osteoarthritis and rheumatoid arthritis: (hint: organize your answer, you can use a chart)a. b. c. d. In case arthroplasty is a treatment option, why this treatment is a constant challenge for biomedical engineering?  Just the d.
