Full Answer

The coracobrachialis is a small muscle that is found just beneath the biceps and at the top of the coracoid process. It allows for the movement of the arm, especially the elbow. Because this muscle is used so often, it is subject to injury and overuse.

The body has two pectoral muscles, which are found in the chest. The pectoralis minor is the smaller of the two. It is a flat muscle that is found right under the larger of the pectoral muscles. It branches up from the third, fourth and fifth ribs to attach to the coracoid process. It allows the scapula to tilt upward and rotate downward.

The biceps brachii has a long and short head. It is the short head that attaches to the coracoid process. This muscle helps the arm flex at the shoulder and at the elbow. It also helps the forearm supinate. This is when the radius is parallel to the ulna while the palm of the hand faces up or out.
