Coracobrachialis

Coracobrachialis (pronunciation: kor-uh-koh-bruh-key-lee-uhs) is a muscle of the human body located in the upper arm. It is one of the muscles that make up the anterior compartment of the arm.

Etymology

The term "coracobrachialis" is derived from the Greek words "korakos" meaning crow, and "brachialis" meaning of the arm. This is in reference to the muscle's point of origin at the coracoid process of the scapula, which is beak-like in shape, and its insertion in the middle third of the humerus, the bone of the upper arm.

Function

The coracobrachialis muscle is responsible for the flexion and adduction of the arm at the shoulder joint. It also assists in stabilizing the shoulder joint.
