Dorsal carpal arch


The dorsal carpal arch is an anatomical term for the combination of dorsal carpal branch of the radial artery and the dorsal carpal branch of the ulnar artery near the back of the wrist.
It is made up of the dorsal carpal branches of both the ulnar and radial arteries. It also anastomoses with the anterior interosseous artery and the posterior interosseous artery. The arch gives off three dorsal metacarpal arteries.
