All are true about anterior compament of leg except
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
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}
