Шаблон:Short description Шаблон:Infobox anatomy
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.
Muscles
The muscles of the compartment are:[1]
| Image | Muscle | Origin | Insertion | Innervation | Main Action |
|---|---|---|---|---|---|
| Файл:Anterior compartment of leg - Tibialis anterior.png | Tibialis anterior | Lateral condyle and superior half of lateral surface of tibia and interosseous membrane | Medial and inferior surfaces of medial cuneiform and base of 1st metatarsal | Deep fibular (peroneal) nerve (L4, L5) |
Dorsiflexes ankle and inverts foot |
| Файл:Anterior compartment of leg - Extensor hallucis longus.png | Extensor hallucis longus | Middle part of anterior surface of fibula and interosseous membrane | Dorsal aspect of base of distal phalanx of great toe (hallux) | Extends great toe and dorsiflexes ankle | |
| Файл:Anterior compartment of leg - Extensor digitorum longus.png | Extensor digitorum longus | Lateral condyle of tibia and superior three quarters of medial surface of fibula and interosseous membrane | Middle and distal phalanges of lateral four digits | Extends lateral four digits and dorsiflexes ankle | |
| Файл:Anterior compartment of leg - Fibularis tertius.png | Fibularis tertius | Inferior third of anterior surface of fibula and interosseous membrane | Dorsum of base of 5th metatarsal | Dorsiflexes ankle and aids in eversion of foot |
Function
The compartment contains muscles that are dorsiflexors and participate in inversion and eversion of the foot.[2]
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.[3]
