The dorsal branch of the ulnar nerve divides into two dorsal digital branches; one supplies the ulnar side of the little finger; the other, the adjacent sides of the little and ring fingers. It also sends a twig to join that given by the superficial branch of the radial nerve for the adjoining sides of the middle and ring fingers, and assists ...
Some languages have different names for hand and foot digits (English: respectively "finger" and "toe", German: "Finger" and "Zeh", French: "doigt" and "orteil").. In other languages, e.g. Arabic, Russian, Polish, Spanish, Portuguese, Italian, Czech, Tagalog, Turkish, Bulgarian, and Persian, there are no specific one-word names for fingers and toes; these are called "digit of the hand" or ...
The common palmar digital nerves of the ulnar nerve are nerves of the hand. The nerve branches off the superficial branch of the ulnar nerve and runs toward the cleft between the ring and little fingers.
The dorsal branch of ulnar nerve arises about 5 cm. proximal to the wrist; it passes backward beneath the Flexor carpi ulnaris, perforates the deep fascia, and, running along the ulnar side of the back of the wrist and hand, divides into two dorsal digital branches; one supplies the ulnar side of the little finger; the other, the adjacent sides of the little and ring fingers.
Each proper digital nerve, opposite the base of the first phalanx, gives off a dorsal branch which joins the dorsal digital nerve from the superficial branch of the radial nerve, and supplies the integument on the dorsal aspect of the last phalanx. At the end of the digit, the proper digital nerve divides into two branches,

Three common palmar digital arteries arise from the convexity of the superficial palmar arch and proceed distally on the second, third, and fourth lumbricales muscles. Alternative names for these arteries are: [ 1 ] common volar digital arteries , [ 2 ] ulnar metacarpal arteries , arteriae digitales palmares communes , [ 3 ] or aa. digitales ...
The palmar digital veins (or volar digital veins) on each finger are connected to the dorsal digital veins by oblique intercapitular veins.. Some sources distinguish between the "proper palmar digital veins", which are more distal, and the "common palmar digital veins", which are more proximal.
