Question 16

80. Explain how muscles work as a pair to bend and straighten the arm at the elbow causing movement at the joint. Discuss type of joint movement

Answer 16

flexion of a joint is a decrease in the joint angle from the body in an anatomic position. when the elbow is bent the forearm is flexed which means that the flexor is contracted or has pulled the bone of the forearm. most flexion takes place in a forward direction. the exception to this is the left where flesh of the leg results in the bending of the knee. extension of the joint is when the joint is returned to anatomic posits ion or increased the angle of the joint, which means the extensor is contracted. an example of this is when the triceps brachi (extensor) contracts to straighten the arm contracts to bend the elbow. Muscles work in pairs so that at the same time, the biceps brachii muscle (flexor) contracts to bend the joint and the triceps brachii returns to its original length. to straighten the arm or extend the joint the triceps brachii (extensor) contracts while the biceps returns to its original length
