In the most distal aspect of this zone, the radial artery divides into four branches which anastomose with similar branches of the ulnar artery, providing the vascularization of the hand: (1) the carpal palmar branch anastomoses with a similar branch of the ulnar artery; (2) the superficial palmar branch, which together with the main trunk of the ulnar artery, forms the superficial palmar arch, that gives the four common digital palmar arteries, (3) the dorsal carpal branch, with a similar ulnar branch, forms the dorsal carpal arch that gives rise to the dorsal metacarpal arteries, and (4) the termination of the RA itself anastomoses with the deep palmar branch of the ulnar artery to form the deep palmar arch.
