| Anatomical terminology | |
The inferior ulnar collateral artery (anastomotica magna artery) is an artery in the arm. It arises about 5 cm. above the elbow from the brachial artery.
Course
It passes medialward upon the
profunda brachii, an arch above the olecranon fossa
.
Branches and anastomoses
As the vessel lies on the brachialis, it gives off branches which ascend to join the
anterior ulnar recurrent
.
Behind the medial epicondyle a branch anastomoses with the superior ulnar collateral and
posterior ulnar recurrent
arteries.
