The coracobrachialis (also coracobrachialis muscle, latin: musculus coracobrachialis) is a small, flat muscle of the upper arm located in the anterior region of the arm.
The coracobrachialis originates from the coracoid process of the scapula.
The coracobrachialis inserts onto the anteromedial surface of the humerus.
The main functions of the coracobrachialis are flexion, adduction and internal rotation of the upper arm.
The coracobrachialis is innervated by the musculocutaneous nerve.
