Muscles
The muscles of the compartment are- tibialis anteriorTibialis anterior muscleIn human anatomy, the tibialis anterior is a muscle that originates in the upper two-thirds of the lateral surface of the tibia and inserts into the medial cuneiform and first metatarsal bones of the foot. Its acts to dorsiflex and invert the foot. This muscle is mostly located near the shin.It is...
- extensor hallucis longusExtensor hallucis longus muscleThe Extensor hallucis longus is a thin muscle, situated between the Tibialis anterior and the Extensor digitorum longus that functions to extend the big toe, dorsiflex the foot, and assists with foot inversion....
- extensor digitorum longusExtensor digitorum longus muscleThe Extensor digitorum longus is a pennate muscle, situated at the lateral part of the front of the leg.-Origin and insertion:It arises from the lateral condyle of the tibia; from the upper three-fourths of the anterior surface of the body of the fibula; from the upper part of the interosseous...
- fibularis tertius (peroneus tertius)
Nerve supply
The anterior compartment of the leg is supplied by the deep fibular nerveDeep fibular nerve
The deep fibular nerve begins at the bifurcation of the common fibular nerve, between the fibula and upper part of the fibularis longus, passes infero-medially, deep to extensor digitorum longus, to the anterior surface of the interosseous membrane, and comes into relation with the anterior...
(deep peroneal nerve).
Blood supply
The compartment of the leg is supplied by anterior tibial arteryAnterior tibial artery
The anterior tibial artery of the lower limb carries blood to the anterior compartment of the leg and dorsal surface of the foot, from the popliteal artery.It is accompanied by a deep vein, the anterior tibial vein, along its course....
