Lateral plantar artery
Encyclopedia
The lateral plantar artery (external plantar artery), much larger than the medial, passes obliquely lateralward and forward to the base of the fifth metatarsal bone.
It then turns medialward 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
.
As this artery passes lateralward, it is first placed between the calcaneus and Abductor hallucis, and then between the Flexor digitorum brevis and Quadratus plantæ as it runs forward to the base of the little toe it lies more superficially between the Flexor digitorum brevis and Abductor digiti quinti
, covered by the plantar aponeurosis and integument.
The remaining portion of the vessel is deeply situated; it extends from the base of the fifth metatarsal bone to the proximal part of the first interosseous space, and forms the plantar arch; it is convex forward, lies below the bases of the second, third, and fourth metatarsal bones and the corresponding Interossei
, and upon the oblique part of the Adductor hallucis.

Dorsalis pedis artery
In human anatomy, the dorsalis pedis artery , is a blood vessel of the lower limb that carries oxygenated blood from the dorsal surface of the foot. It arises at the anterior aspect of the ankle joint and is a continuation of the anterior tibial artery...

Abductor digiti minimi muscle (foot)
The Abductor digiti minimi is a muscle which lies along the lateral border of the foot, and is in relation by its medial margin with the lateral plantar vessels and nerves....

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:...
