Extensor hallucis longusDeep peroneal nerveDorsiflexor of foot and extends metatarsophalangeal and interphalangeal joints of the big toe.3. Extensor digitorum longusDeep personal nerveDorsiflexor of the foot. Extends metatarsophalangeal, proximal and distal interphalangeal joints of 2nd-5th toes.4. Peroneus TertiusDeep peroneal nerveDorsiflexor of foot and evertor of the foot.5. Extensor digitorum brevisLateral terminal branch of the deep peroneal nerveMedial tendon known as extensor hallucis brevis extends metatarsophalangeal joint of the big toe. The other three lateral tendons extend the metatarsophalangeal and interphalangeal joints of 2nd, 3rd, and 4th toes, particularly in a dorsiflexed foot.Muscles of the lateral compartment of the leg The peroneal musclesMusclesNerve supplyAction1. Peroneus IongusSuperficial peroneal nervea) Everton of foot especially when the foot is off the groundb) Maintain lateral longitudinal arch and transverse arch of the foot.Peroneus longus and tibialis anterior are inserted into the same two bones, the two together form a 'stirrup' beneath the middle of the sole. The presence of the sling keeps the middle of foot pulled up and prevents flattening of its arches.2. Peroneus brevisSuperficial peroneal nerveEvertor of foot
