Coracobrachialis

Coracobrachialis is a muscle of the human body that is located in the upper arm. It is one of the muscles that make up the anterior compartment of the arm, along with the biceps brachii and brachialis muscles. The coracobrachialis muscle is the smallest of the three muscles and is situated at the upper and medial part of the arm.

Anatomy

The coracobrachialis muscle originates from the coracoid process of the scapula. Its fibers run in a downward and lateral direction, to insert into the middle third of the medial surface of the humerus.

Function

The coracobrachialis muscle assists in flexion and adduction of the arm at the shoulder joint. It also acts to stabilize the humerus by drawing it forward and towards the body during arm movement.

Clinical significance

Injury or strain to the coracobrachialis muscle can result in pain and limited movement of the arm. This can occur as a result of overuse, trauma, or improper lifting techniques. Treatment typically involves rest, physical therapy, and in some cases, surgery.
