Document Summary
Anterior and posterior compartments that is divided by a facial septum on each side of the humerus: anterior compartment (coracobrachialis, brachialis, bicep brachii) elbow flexors. Note: its 3 heads are analogous to the biceps & brachialis. Short head: coracoid process (next to origin of coracobrachialis) Ulna tubercle (fibers congregate to insert here, distal to the elbow) Radial tubercle (majority of insertion) + radial aponeurosis (which fans out medially over top forearm flexors) (2x heads fuse half way down the humerus large fleshy belly stout tendon) 3x heads coalesce into an aponeurosis gives rise to stout tendon crosses behind elbow to insert on the. Brachial artery initially runs down the medial side of the humerus. About halfway down the humerus, it moves to the anterior to cross the elbow joint. It is accompanied most of the way by the median nerve. As the brachial artery enters the forearm (as it crosses the elbow), it bifurcates into: radial artery, ulnar artery.
