Plantar arch
The plantar arch is a circulatory anastomosis formed from:
- deep plantar artery, from the dorsalis pedis - a.k.a. dorsal artery of the foot
- lateral plantar artery
The plantar arch runs from the 5th metatarsal and extends medially to the 1st metatarsal.
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.
