All are true about anterior compament of leg except
ANTERIOR COMPAMENT( leg):- Muscles:- 1. Tibialis anterior 2. Extensor hallucis longus 3. Extensor digitorum longus 4. Peroneus teius. Aery:anterior tibial aery.The blood supply of anterior compament is reinforced by the perforating branch of peroneal aery. Nerve:-Deep peroneal nerve. Muscle action:- 1. Tibialis anterior-Dorsiflexor of foot,inveor of foot,keeps leg veical while walking on uneven ground, maintain medial longitudinal arch of foot. 2. EHL:- Dorsiflexor of foot,extends metatarsophalangeal and interphalangeal joint of big toe. 3. EDL:- Dorsiflexor of foot,extends metatarsophalangeal ,proximal and distal interphalangeal joint of 2nd-5th toe. 4. Peroneus teius-Dorsiflexor and eveor of foot. 5. Extensor digitorum longus-medial tendon known as the extensor hallucis brevis,extends metatarsophalangeal joint of big toe.The other three lateral tendon extends the metatarsophalangeal and interphalangeal joints of 2 nd 3 rd and 4 th toe paicularly in dorsiflexed foot. Peroneus longus is muscle of lateral compament. {Reference: BDC 6E}
Tibialis anterior causes dorsiflexion of foot
EHL causes extension of MTP joint of big toe
Peroneus longus causes eversion of foot
Nerve supply is through deep peroneal nerve
