Superior Ulnar Collateral Artery

Wednesday, September 14, 2011

The superior ulnar collateral artery is an oxygen-rich blood vessel which originates from the brachial artery and supplies part of the upper arm. Having branched from the brachial artery, the superior ulnar collateral runs down the arm to the elbow as it follows the route of the ulnar nerve. Under the flexor carpi ulnaris, the superior ulnar collateral anastomoses with the posterior ulnar recurrent and inferior ulnar collateral.
