Inflammation occurs in the joint, and the fluid that accumulates causes swelling, stiffness, impairment of joint movement, and extreme pain. ANS: D Feedback A Synovial joints have a cavity. The calcium allows the myosin heads to latch on to the actin filaments and the muscle contraction occurs. b. Synovial joints are places where bones articulate with each other inside of a joint cavity. What is the most common cause of hip disability? Synovial joints are places where bones articulate with each other inside of a joint cavity. A synovial membrane Paralysis, because all ACh must be bound to a receptor for contraction to occur Long protein bundles htat fill the sarcoplasmand store glycogen, What is the chief function of T tubules?
