Coracobrachialis muscle

The coracobrachialis muscle is a muscle that connects the scapula (shoulder blade) to the humerus. When contracted, it brings the arm forward and inward.

Origin
The coracobrachialis originates at the coracoid process of the scapula.

Insertion
The coracobrachialis inserts into the body of the humerus.

Innervation
The coracobrachialis is innervated by the lateral cord of the musculocutaneous nerve (C5-C7).

Word origin
The word coracobrachialis refers to the two endpoints of the muscle: the coracoid process and the brachialis, Latin for arm.
