Dorsal metatarsal arteries

Dorsal Metatarsal Arteries are a group of arteries in the foot that supply blood to the dorsal aspect of the metatarsal bones and the phalanges. They are branches of the dorsalis pedis artery and are typically four in number, corresponding to the interosseous spaces of the foot.

Etymology

The term "Dorsal Metatarsal Arteries" is derived from the Latin words "dorsum" meaning back, "metatarsus" referring to the part of the foot between the ankle and the toes, and "arteria" meaning windpipe, which later came to denote the vessels that carry blood from the heart.

Anatomy

The dorsal metatarsal arteries arise from the arcuate artery, a branch of the dorsalis pedis artery. They run forward in the interosseous spaces and each divides into two branches for the adjacent sides of the corresponding toes. The first dorsal metatarsal artery, the largest, is a continuation of the dorsalis pedis artery and supplies the medial side of the big toe.

Clinical Significance

The dorsal metatarsal arteries, like other arteries in the foot, can be affected by peripheral artery disease, a common condition in which plaque builds up in the arteries that carry blood to the head, organs, and limbs. This can lead to reduced blood flow, which can cause pain and delay healing of injuries or infections in the foot.
