ulnar artery

a large artery branching from the brachial artery, supplying muscles in the forearm, wrist, and hand. Arising near the elbow, it passes obliquely in a distal direction to become the superficial palmar arch. It has nine branches: four in the forearm, two in the wrist, and three in the hand.

It supplies blood to the forearm, the medial side of the wrist, the palm, and the hand, and its branches include the common interosseous, the anterior and posterior ulnar recurrent, the palmar carpal, and the dorsal carpal arteries.
