Superior ulnar collateral artery

Other Terms: Arteria collateralis ulnaris superior, Artère collatérale ulnaire supérieure

Description

The superior ulnar collateral artery is a small vessel which arises from the brachial near the insertion of the coracobrachialis. It passes downward and medially on the surface of the medial head of the triceps. It pierces the medial intermuscular septum and accompanies the ulnar nerve between the medial epicondyle and the olecranon, where it anastomoses with the posterior ulnar recurrent and the inferior ulnar collateral. In front of the medial epicondyle, it also sends a small branch downward that anastomoses with the anterior ulnar recurrent and the inferior ulnar collateral. Sometimes, it arises with the deep brachial artery by a common trunk.
