Coracobrachialis Muscle

The coracobrachialis is a muscle of the ventral muscle group with insertion on the humerus, arising from the coracoid process of the scapula together with the short head of the biceps brachii. It is inserted in the medial surface of the humerus on the continuation of the crest of the lesser tubercle. The coracobrachialis anteverts (draws forwards) the upper arm and also holds the head of the humerus in its joint socket. It is supplied by the brachial artery and is innervated by the musculocutaneous nerve.
