Plantar metatarsal arteries
Encyclopedia
The plantar metatarsal arteries (digital branches) 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.
Near their points of division each sends upward an anterior perforating branch to join the corresponding dorsal metatarsal artery
.
The first plantar metatarsal artery (arteria princeps hallucis) springs from the junction between the lateral plantar and deep plantar arteries and sends a digital branch to the medial side of the first toe.
The digital branch for the lateral side of the fifth toe arise from the lateral plantar artery
near the base of the fifth metatarsal bone

Interossei
Interossei refer to muscles between certain bones. There are many interossei in a human body. Specific interossei include:-On the hands:* Dorsal interossei muscles of the hand* Palmar interossei muscles-On the feet:...

Dorsal metatarsal artery
Dorsal metatarsal artery can refer to:* the first dorsal metatarsal artery* the second, third, and fourth dorsal metatarsal arteries, which branch off the arcuate artery of the foot...

Fifth metatarsal bone
The fifth metatarsal bone is recognized by a rough eminence, the tuberosity, on the lateral side of its base.The base articulates behind, by a triangular surface cut obliquely in a transverse direction, with the cuboid; and medially, with the fourth metatarsal.On the medial part of its dorsal...
