Dorsal metatarsal arteries
Encyclopedia
The arcuate artery of the foot
gives off the second, third, and fourth dorsal metatarsal arteries, which run forward upon the corresponding Interossei dorsales
; in the clefts between the toes, each divides into two dorsal digital branches for the adjoining toes.
At the proximal parts of the interosseous spaces these vessels receive the posterior perforating branches from the plantar arch
, and at the distal parts of the spaces they are joined by the anterior perforating branches, from the plantar metatarsal arteries
.
The fourth dorsal metatarsal artery gives off a branch which supplies the lateral side of the fifth toe
.
The first dorsal metatarsal artery
runs forward on the first Interosseous dorsalis.
Arcuate artery of the foot
The arcuate artery of the foot arises a little anterior to the lateral tarsal artery; it passes lateralward, over the bases of the metatarsal bones, beneath the tendons of the Extensor digitorum brevis, its direction being influenced by its point of origin; and its anastomoses with the lateral...

Plantar metatarsal arteries
The plantar metatarsal arteries are four in number, and run forward between the metatarsal bones and in contact with the Interossei.Each divides into a pair of plantar digital arteries which supply the adjacent sides of the toes....

Fifth toe
The fifth toe is the outermost and usually the smallest toe of the foot.It is associated with many medical conditions, largely due to the use of shoes....

First dorsal metatarsal artery
The first dorsal metatarsal artery runs forward on the first Interosseous dorsalis, and at the cleft between the first and second toes divides into two branches, one of which passes beneath the tendon of the Extensor hallucis longus, and is distributed to the medial border of the great toe; the...
