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.
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.

Famous quotes containing the word arch:
“Men themselves have wondered
What they see in me.
They try so much
But they cant touch
My inner mystery.
When I try to show them,
They say they still cant see.
Its in the arch of my back,
The sun of my smile,
The ride of my breasts,
The grace of my style.
Im a woman
—Maya Angelou (b. 1928)
