Plantar arch
The plantar arch is a circulatory anastomosis formed from: The plantar arch supplies the underside, or sole, of the foot.The plantar arch runs from the 5th metatarsal and extends medially to the 1st metatarsal (of the big toe).The arch is formed when the lateral plantar artery turns medially to the interval between the bases of the first and second metatarsal bones, where it unites with the deep plantar branch of the dorsalis pedis artery, thus completing the plantar arch (or deep plantar arch).This article incorporates text in the public domain from page 639 of the 20th edition of Gray's Anatomy (1918)
