Arteries Finger Dorsal

The digital dorsal arteries are a bundle of three arteries that run along the lateral surfaces of the metacarpal bones and the bases of the toes. They supply blood to the skin, bone and muscle tissue of the arms and legs.

The digital dorsal artery runs along the lateral surfaces of the metacarpal bone, then turns and passes into the area of ​​the base of the big toe and the sole of the foot. It passes between the dorsal interosseous membrane and the lateral interosseous ligament, where it emerges on the surface of the skin of the big toe. The digital dorsal artery then turns perpendicular to its original trajectory and continues on the toes towards their distal ends. There it divides into two smaller arteries - the first and second branches, which supply blood to the bones and skin of the arm and leg, respectively.

From the arterial system of the thumb, the digital dorsal artery system may continue to the other fingers and toes. These lateral digital arteries correspond to the arteries of one of the palmar main arteries. The digital arterial vascular arches are located on the lateral surfaces of the fingers, corresponding to the arterial oblique thumb of the limb. The vascular vessels of the thumb go to the dorsal digital artery, which continues as palmar branches.
