Palmar carpal arch
From Wikipedia, the free encyclopedia
The palmar carpal arch is an anatomical term that denotes the combination (anastomosis) of two arteries: the palmar carpal branch of the radial artery and the palmar carpal branch of the ulnar artery.

[edit] Palmar carpal branch of the radial artery
The palmar carpal branch of the radial artery is a small branch of the radial artery which arises near the lower border of the pronator quadratus, and, running across the front of the carpus, anastomoses with the palmar carpal branch of the ulnar artery.
[edit] Palmar carpal branch of the ulnar artery
The palmar carpal branch of the ulnar artery is a small branch of the ulnar artery which crosses the front of the carpus beneath the tendons of the flexor digitorum profundus, and anastomoses with the corresponding branch of the radial artery.
[edit] Palmar carpal arch
The palmar carpal arch is the combination of the palmar carpal branches from both the radial and ulnar arteries. 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.
