Anterior compartment of leg nerve skin#

Skin of the plantar surface of the toes and dorsal surface of the distal interphalangeal segment (to the lateral side of the 5th toe)įlexor hallucis brevis m. (to the medial side of the great toe) superficial br. "peroneal" is old terminology which has been replaced by "fibular" anterior compartment syndrome - trauma to the anterior side of the leg can result in pressure buildup in the anterior compartment (from swelling or bleeding) that can damage the deep fibular n., resulting in "foot drop"Ĭommon plantar digital medial plantar n. Skin of the web between the great toe and the 2nd toe Muscles of the anterior compartment of the leg (tibialis anterior m., extensor hallucis longus m., extensor digitorum longus m., fibularis tertius m.) and muscles of the dorsum of the foot (extensor digitorum brevis m.and extensor hallucis brevis m.) The dorsal surfaces of the distal tips of the toes (nail bed regions) are supplied by the proper plantar digital brs. Skin of the plantar surface of the toes (except the medial side of the great toe and the lateral side of the 5th toe) "peroneal" is old terminology which has been replaced by "fibular" Superficial fibular n.: distal 1/3 of the anterior surface of the leg, dorsum of the foot excluding the web between the great toe and the 2nd toe and distal interphalangeal segments of all toes deep fibular n.: skin of the web between the great toe and the 2nd toe Superficial fibular n.: muscles of the lateral compartment of the leg (fibularis longus and brevis mm.) deep fibular n.: muscles of the anterior compartment of the leg (tibialis anterior m., extensor hallucis longus m., extensor digitorum longus m., fibularis tertius m.) and muscles of the dorsum of the foot (extensor digitorum brevis m.and extensor hallucis brevis m.) Lateral sural cutaneous n., superficial and deep fibular nn.

Only part of the S4 ventral primary ramus is contributed to the coccygeal plexus Ventral primary rami of spinal nerves S4, S5, C1

Skin of the superomedial portion of the buttock Skin of the intermediate medial portion of the buttock Lateral cutaneous branches of the dorsal primary rami of spinal nerves S1-3 carry postganglionic sympathetic axons to skin Innervation: Superficial fibular (peroneal) nerve.Cutaneous nn.Also supports the lateral and transverse arches of the foot. Actions: Eversion and plantarflexion of the foot.The tendon crosses under the foot, and attaches to the bones on the medial side, namely the medial cuneiform and base of metatarsal I.The fibres converge into a tendon, which descends into the foot, posterior to the lateral malleolus.

The fibularis longus originates from the superior and lateral surface of the fibula and the lateral tibial condyle.

The fibularis longus is the larger and more superficial muscle within the compartment. In reality, the job of these muscles is to 'fix' the medial margin of the foot during running, and prevent excessive inversion. Note: From the anatomical position, only a few degrees of eversion are possible. In this article, we shall look at the anatomy of the muscles in the lateral compartment of the leg - their attachments, innervation and actions. They are both innervated by the superficial fibular nerve. The common function of the muscles is eversion – turning the sole of the foot outwards. There are two muscles in the lateral compartment of the leg the fibularis longus and brevis (also known as peroneal longus and brevis).
