26
Q
  1. Explain how muscle work as a pair and straighten the arm at the elbow causing movement at the joint. Make sure you discuss the type of joint movement
A

Flexion of a joint is a decrease in the joint angle from the body in anatomic position. When the elbow is bent the forearm is flexed which means that the flexor is contracted or had pulled the bone of the forearm. Most flexion takes place in a forward direction. The exception to this is the leg the flexion of the leg results in the bending of the knee. Extension of the joint is when the joint is returned to anatomic position or increased the angle of the join, which means the extensor is contracted. An example of this is when the triceps brachii extensor contracts to straighten the arm. The biceps brachi muscle (flexor) in the upper arm contracts to bend the elbow. Muscles work in pairs so that st the same time, the biceps brachii muscle(flexor) contracts to bend the joint and the triceps brachi return to its original length. To straighten the arm or extend the joint, the triceps brachii (extensor) contracts while the biceps brachi returns to its original length
