Ulnar artery

The ulnar artery branches off from the brachial artery below the bend of the elbow, at the area known as the cubital fossa. It runs the length of the forearm and ends at the superficial palmar arch.  Here, it joins with the radial artery.  The superficial palmar arch is also known as the superficial volar arch. The ulnar artery, like its radial counterpart, delivers oxygenated blood to the forearm and the smaller arteries in the hand. These arteries should not be confused with veins. The similarly-named veins drain oxygen-depleted blood away from the forearm and hands. Once the radial and ulnar arteries join, the artery branches into smaller vessels. These are known as the common palmar digital arteries. Other branches of the ulnar arteries include the posterior and anterior ulnar recurrent arteries. Both are located near the elbow.
