Lateral plantar artery

from Wikipedia, the free encyclopedia
Plantar arteries of man

The lateral plantar artery (“external plantar artery ”) is a carotid artery on the foot .

human

In humans, the lateral plantar artery is the stronger of the two branches of the posterior tibial artery . It runs on the sole of the foot between the flexor digitorum brevis muscle and the quadratus plantae muscle , to the side of the lateral plantar nerve , diagonally to the side and towards the base of the toe. It supplies the skin and muscles on the outer side of the foot and anastomoses with the lateral tarsal artery and the arcuate artery . At the base of the fifth metatarsal bone , the lateral plantar artery flows into the deep arch of the plantar soles ( Arcus plantaris profundus ) and thus also takes over the blood supply to the soles of the toes.

Comparative anatomy

In animals, the lateral plantar artery of the weaker of the two branches is the Ramus caudal the artery vein . In horses, it feeds the superficial plantar arterial system ( Arteriae digitales plantares communes ) together with the arteria plantaris medialis . In general, the lateral plantar artery feeds into the deep plantar arch and thus participates - albeit to a lesser extent - in the blood supply to the hind foot.
