The three common digital nerves (nn. digitales plantares communes) pass between the divisions of the plantar aponeurosis, and each splits into two proper digital nerves—those of the first common digital nerve supply the adjacent sides of the great and second toes; those of the second, the adjacent sides of the second and third toes; and those of the third, the adjacent sides of the third and ...
One nerve (calcaneal) continues to the heel, the other two (medial and lateral plantar nerves) continue on to the bottom of the foot. The tarsal tunnel is delineated by bone on the inside and the flexor retinaculum on the outside. People with TTS typically complain of numbness in the foot radiating to the big toe and the first three toes, pain ...
The medial plantar nerve supplies: the abductor hallucis, the flexor digitorum brevis, the flexor hallucis brevis and the first lumbrical.Cutaneous distribution of the medial plantar nerve is to the medial sole and medial three and one half toes, including the nail beds on the dorsum (like the median nerve in the hand).
Lower limb. Foot. Cutaneous innervation of the lower limbs is the nerve supply to areas of the skin of the lower limbs (including the feet ) which are supplied by specific cutaneous nerves . Modern texts are in agreement about which areas of the skin are served by which nerves , but there are minor variations in some of the details.
Inserts on the dorsal side of the base of the distal phalanx of the big toe: Artery: Anterior tibial artery: Nerve: Deep fibular nerve, L5 (L4-S1) Actions: Extends (raises) the big toe and assists in dorsiflexion of the foot at the ankle.

The extensor hallucis brevis is essentially the medial part of the extensor digitorum brevis muscle. Some anatomists have debated whether these two muscles are distinct entities.
Medial Head: Medial sesamoid bone of the metatarsophalangeal joint, proximal phalanx of great toe.
