| Latin: | rete carpale palmare |
| Branchfrom: | Palmar carpal branch of radial artery and palmar carpal branch of ulnar artery |
The palmar carpal arch is a joining of an artery to an artery, a circulatory anastomosis, known as an arterio-arterial anastomosis. The two connected arteries are the palmar carpal branch of the radial artery and the palmar carpal branch of the ulnar artery.
This anastomosis is joined by a branch from the anterior interosseous artery above, and by recurrent branches from the deep palmar arch below, thus forming a palmar carpal network which supplies the articulations of the wrist and carpus.
