The dorsal digital arteries of the foot supply freshly oxygenated blood to the toes. They are collateral digital branches of the dorsal metatarsal arteries in the foot.
These vessels also occur in the hand but, unlike the palmar arteries, the dorsal digital arteries do not quite reach the distal (end) digit.
The dorsal digital arteries of the foot carry blood from the heart to the toes. These arteries are flexible and elastic and made of three layers, including one layer that is muscular. The muscular layer works to contract the artery in rhythm, helping to pump the blood throughout the body.
The dorsal digital arteries of the foot are susceptible to clogging of the arteries or buildup of fat in the arteries that can lead to atherosclerosis. The clogging or buildup of fat in the dorsal digital arteries of the foot can cause a loss of circulation to the area of the toes in the feet.
