The anterior muscles of the arm are the biceps, brachioradialis and brachialis. These muscles are strong flexors. The triceps muscle is the posterior muscle of the arm and extends or straightens the arm.
The medial epicondyle of the humerus serves as an attachment point for the tendons of the wrist flexors. The lateral epicondyle of the humerus serves as the attachment point for the tendons of the wrist extensors.
A tendon is the part of the muscle that attaches to a bone. Common overuse injuries for these tendons are the medial epicondylitis (golfers elbow) and lateral epicondylitis (tennis elbow.) There are also deep muscles of the forearm that help to pronate (palm down) and supinate (palm up) the hand.
