Arteries of the forearm: Anterior view (English)

Oxygenated blood reaches the elbow and forearm via the large brachial artery, and its largest branch, the deep brachial artery. Upon entering the cubital fossa the brachial artery immediately divides into the two major arteries of the forearm: the ulnar and radial arteries. Branches from the brachial, ulnar and radial arteries anastomose to form the cubital anastomosis. Shortly after its origin, the ulnar artery gives off the common interosseous artery which further bifurcates into anterior and posterior interosseous arteries. The anterior interosseous artery extends along the interosseous membrane of the forearm and gives off the median artery which accompanies the median nerve to the hand. The ulnar and radial arteries then descend through the forearm, giving off several muscular branches along their lengths, before terminating in the arterial arches of the hand.
