Ulnar Artery

The ulnar artery is a large blood vessel which supplies the muscles of the forearm and wrist and hand with oxygenated blood. The ulnar artery branches from the brachial artery just below the bend of the elbow in the cubital fossa and travels down along the length of the ulna bone, ending in the superficial palmar arch, which joins with the superficial branch of the radial artery. It gives off the anterior ulnar recurrent artery, the posterior ulnar recurrent artery, common interosseous artery. At the wrist, branches of the ulnar and radial arteries join to form a network of vessels, which supply the structures in the wrist, hand and fingers.
