When a muscle acts to move a bone, it's point of origin (which is usually the end of the muscle closest to the axial skeleton)is held fairly stable so that the contraction of the muscle pulls the bone to which it inserts into towards it, in a lever-like action across the joint, which acts as a pivot.very muscle works with another muscle (or several others). The acting muscle is known as the agonist, and the 'partner' muscles are called the antagonists. The antagonist's action is the opposite of the agonist's action, and helps to control the movement and prevent injury.
