- origin: branch of the brachial artery superior to the medial epicondyle 1
- location: distal lower arm
- supply: brachialis, biceps brachii, and coracobrachialis 1
- main branches: anterior ulnar recurrent artery (anastamoses), and branch to superior ulnar collateral artery 1
The inferior ulnar collateral artery arises medially from the brachial artery superior to the medial epicondyle. Before passing anterior to the medial epicondyle, it provides a branch to the superior ulnar collateral artery 1.
The inferior ulnar collateral artery anastomoses with the anterior ulnar recurrent artery anterior to the medial epicondyle 1.
The inferior ulnar collateral constitutes part of the supply to the brachialis, biceps brachii, and coracobrachialis muscles. It also provides a branch to the superior ulnar collateral artery which partly supplies the elbow joint 1.
