While lifting weights during football season, a player hears a loud "pop." This is primarily associated with a loss of which function?
A) Autonomic nerve fibers
B) Supporting bursa sacs
C) Reflexive proprioception
D) Elastic articular cartilage
Ans: C
Feedback:
Tendons and ligaments of the joint capsule connect muscles and bones, are sensitive to position and movement, and have reflexive proprioceptor responses to adjust and maintain supporting muscle tension for the joint. The joint capsule synovial membrane is innervated only by autonomic fibers that control blood flow. Bursae, closed sacs of synovial fluid, prevent friction in areas where tendons are deflected over bone, rather than maintaining muscle support. Cartilage is devoid of blood vessels and nerves; elastic-type cartilage is found in areas such as the ear.
