Its action is mainly antagonist to the action of the Deltoid. Insertion: Medial surface of the middle of the shaft of the humerus, opposite the deltoid tuberosity (11, 20). Brachialis. Note again the insertion of pectoralis minor. It then lies upon the medial head of the Triceps brachii, next upon the insertion of the Coracobrachialis, and lastly on the Brachialis. Their common tendon of origin arises from the coracoid process. Its insertion is to the middle of the humerus. Innervation. The levator ani muscle along with a second muscle forms the pelvic floor. Avulsion of the muscle's origin from the coracoid as a result of indirect forces is even more unusual. The Coracobrachialis receives its supply primarily from the seventh cervical, the Biceps brachii and Brachialis from the fifth and sixth cervical nerves. Coracobrachialis Muscle - Origin, Insertion.
