Normal AnatomyRadial artery
smaller terminal branch of the
brachial artery which begins about one cm distal to the
elbow joint. It passes along the radial side of the
forearm, curls posterolaterally around the
wrist to reach the first intermetacarpal space. It then passes medially into the palm to form the deep palmar arch with the deep palmar branch of the
ulnar artery. It is divided into three parts; in the forearm, wrist and hand. Gives origin to the radial recurrent, muscular, palmar carpal, superficial palmar, dorsal carpal, first dorsal metacarpal arteries and arteria princeps pollicis, the arteria radialis indicis and the deep palmar arteries.
