Dorsal carpal branch of the ulnar artery
|Dorsal carpal branch of the ulnar artery|
Arteries of the back of the forearm and hand.
|Branches||dorsal carpal arch|
|Latin||ramus carpalis dorsalis arteriae ulnaris|
The dorsal carpal branch of the ulnar artery arises from the ulnar artery immediately above the pisiform bone, and winds backward beneath the tendon of the flexor carpi ulnaris; it passes across the dorsal surface of the carpus beneath the extensor tendons, to anastomose with a corresponding branch of the radial artery.
Immediately after its origin, it gives off a small branch, which runs along the ulnar side of the fifth metacarpal bone, and supplies the ulnar side of the dorsal surface of the little finger.
