Arcuate artery

The arcuate artery (Latin: arteria arcuata) of the foot is a branch of the dorsalis pedis artery. It runs along the dorsal side of the foot and provides arterial blood supply to adjacent muscles of the foot, metatarsal bones and toes (2nd, 3rd, 4th).

The arcuate artery arises near the medial cuneiform and passes laterally from the first interosseous space over the bases of the metatarsal bones, beneath the tendons of the extensor digitorum brevis muscle. It gives rise to the 2nd, 3rd, and 4th dorsal metatarsal arteries, which run to the interosseous spaces, where each metatarsal artery divides into two dorsal digital arteries.
