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. Also is a weak evertor/invertor: Antagonist: Flexor hallucis longus, flexor hallucis brevis: Identifiers; Latin
The flexor digitorum longus runs along the medial posterior side of the lower leg and aids in flexions of the toes (apart from the big toe). The flexor digitorum longus muscle arises from the posterior surface of the body of the tibia, from immediately below the soleal line to within 7 or 8 cm of its lower extremity, medial to the tibial origin of the tibialis posterior muscle.
The medial dorsal cutaneous nerve (internal dorsal cutaneous branch) passes in front of the ankle-joint, and divides into three dorsal digital branches, one of which supplies the medial side of the great toe, the other, the adjacent sides of the second and third toes. The intermediate dorsal cutaneous nerve divides into four dorsal digital ...
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.
Nerves have historically been considered the basic units of the peripheral nervous system. A nerve provides a common pathway for the electrochemical nerve impulses called action potentials that are transmitted along each of the axons to peripheral organs or, in the case of sensory nerves, from the periphery back to the central nervous system.
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.
The oblique head is a large, thick, fleshy mass, crossing the foot obliquely and occupying the hollow space under the first, second, third and fourth metatarsal bones. It arises from the bases of the second, third, and fourth metatarsal bones, and from the sheath of the tendon of the Peroneus longus, and is inserted, together with the lateral portion of the flexor hallucis brevis, into the ...
Flexor hallucis brevis muscle arises, by a pointed tendinous process, from the medial part of the under surface of the cuboid bone, from the contiguous portion of the third cuneiform, and from the prolongation of the tendon of the tibialis posterior muscle which is attached to that bone.
