anterior compartment of leg anterior compartment of leg the anterior compartment of the leg is a fascial compartment of the lower leg. it contains muscles that produce dorsiflexion and participate in inversion and eversion of the foot, as well as vascular and nervous elements, including the anterior tibial artery and veins and the deep fibular nerve. anterior compartment of legcross-section through middle of leg. anterior compartment is shown right to the tibia.dissection video (2 min 44 s)detailsarteryanterior tibial arterynervedeep fibular nerveidentifierslatincompartimentum cruris anteriusta98a04.7.01.005ta22643fma45163anatomical terminology muscles the muscles of the compartment are: tibialis anterior extensor hallucis longus extensor digitorum longus fibularis (peroneus) tertius imagemuscleorigininsertioninnervationmain action tibialis anteriorlateral condyle and superior half of lateral surface of tibia and interosseous membranemedial and inferior surfaces of medial cuneiform and base of 1st metatarsaldeep fibular (peroneal) nerve (l4, l5)dorsiflexes ankle and inverts foot extensor hallucis longusmiddle part of anterior surface of fibula and interosseous membranedorsal aspect of base of distal phalanx of great toe (hallux)extends great toe and dorsiflexes ankle extensor digitorum longuslateral condyle of tibia and superior three quarters of medial surface of fibula and interosseous membranemiddle and distal phalanges of lateral four digitsextends lateral four digits and dorsiflexes ankle fibularis tertiusinferior third of anterior surface of fibula and interosseous membranedorsum of base of 5th metatarsaldorsiflexes ankle and aids in eversion of foot function the compartment contains muscles that are dorsiflexors and participate in inversion and eversion of the foot. innervation and blood supply the anterior compartment of the leg is supplied by the deep fibular nerve (deep peroneal nerve), a branch of the common fibular nerve. the nerve contains axons from the l4, l5, and s1 spinal nerves. blood for the compartment is supplied by the anterior tibial artery, which runs between the tibialis anterior and extensor digitorum longus muscles. when the artery crosses the extensor retinaculum, it changes its name to dorsalis pedis artery. additional images anterior compartment. animation. notes and references moore, dally, and agur (2014). moore clinically oriented anatomy, table 5.10, p 591. antlegdorsalfoot at the anatomy lesson by wesley norman (georgetown university) "vessels and lympatic drainage of the lower limb". retrieved 11 january 2015.
