A contracture: Is the lack of joint mobility caused by abnormal shortening of a muscle Is the decrease in size or the wasting away of tissue Is usually not painful Occurs most commonly in the neck and spine

A motor unit is a motor neuron and all the muscle fibers that it controls. A single motor unit may innervate many muscle fibers and can result in constant tension as individual motor neurons cycle between contraction and relaxation. A motor unit is a motor neuron and the muscle fiber that it controls. A single motor unit may innervate only one muscle fiber and can result in constant tension of the muscle. A single muscle fiber may be innervated by multiple motor neurons which result in constant tension as multiple motor neurons cycle between contraction and relaxation. No option is correct. The following is characteristic of aging muscle EXCEPT: Skeletal muscle becomes smaller in diameter Skeletal muscle becomes less elastic due to an increase in fibrous connective tissue Ability to recover from muscular injuries decreases due to decreased number of myosatellite cells Ability to recover from muscular injuries decreases due to increased number of myosatellite cells

Alterations in joint mobility may predispose the joint to developing osteoarthritis because: A) Instability may lead to surface stresses that are different from the usual plane of motion which leads to surface fibrillation of cartilage B) Hypomobility may produce chronically elevated joint pressures that lead to cartilage degeneration C) Hypomobility may limit the joint surface area used to distribute forces during loading D.All of the above are true E.Only B and C are true
