Medial intermuscular septum of arm

Jump to navigation Jump to search

Template:Infobox Anatomy The medial intermuscular septum, thicker than the lateral intermuscular septum, extends from the lower part of the crest of the lesser tubercle of the humerus below the Teres major, along the medial supracondylar ridge to the medial epicondyle; it is blended with the tendon of the Coracobrachialis, and affords attachment to the Triceps brachii behind and the Brachialis in front.

It is perforated by the ulnar nerve, the superior ulnar collateral artery, and the posterior branch of the inferior ulnar collateral artery.
