Radial Artery

The radial artery is a major blood vessel which carries oxygenated blood and follows the course of the radius (bone) on the ventral side of the forearm to the wrist, where it is felt as a pulse as it goes into the hand. The radial artery supplies blood to muscles of the forearm, the thumb, and index finger. It begins where the brachial artery bifurcates into two arteries in the cubital fossa (the other being the ulnar artery), giving off the radial recurrent artery before traveling down along the radius bone. Having passed anteriorly between the heads of the adductor pollicis muscle, the radial artery becomes the deep palmar arch, which joins with the deep branch of the ulnar artery, giving off the princeps pollicis artery (of the thumb) and the radialis indicis artery (of the index finger).
