The coracobrachialis

Coracobrachialis · musculus coracobrachialis

A slim muscle on the inner upper arm that draws the arm forward and in.

What it does

The coracobrachialis runs from a hook-like process on the front of the shoulder blade to the middle of the humerus. It helps bring the arm forward and towards the body, and holds the head of the humerus in its socket when the arm hangs.
