Dorsal Carpal Arteries/Veins

The "dorsal carpal branch" of the radial and ulnar arteries supply blood to the "dorsal digital branches," which then supply the sides of the index, middle, ring, and little fingers. The dorsal digital vessels form a network of blood vessels and nerves with the proper palmar digital branches of the superficial palmar arch. The dorsal veins parallel the arteries of the same name on their way back up to the radial and ulnar veins. Dorsal veins and arteries are also found in the feet which are also responsible for the supply to and the draining of blood supplied to the top of the foot.
