Anatomical terminology

Muscles[edit]

The muscles of the compartment are[1]

Muscle Proximal Attachment Distal Attachment Innervation Main Action
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 nerve
(L4, L5)
Dorsiflexes ankle and inverts foot
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
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
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

[2]

Action[edit]

The muscles of the compartment are dorsiflexors of foot.[3]

Nerve supply[edit]

The anterior compartment of the leg is supplied by the deep fibular nerve (deep peroneal nerve). The nerve contains axons from the L4, L5, and S1 spinal nerves.

Blood supply[edit]

The compartment of the leg is supplied by anterior tibial artery.[1]

The structures of anterior compartment can be remembered using the mnemonic, "TEA DEPt" for Tibialis anterior, Extensor hallucis longus, Anterior tibial artery, Deep peroneal nerve, Extensor digitorum longus and Peroneus tertius.[1]
