During these periods, excessive pressure can be exerted on the peroneus tertius tendon, which runs along the lateral side of the foot.
2.
It is innervated by the deep fibular nerve, unlike the other peroneal muscles which are innervated by the superficial fibular nerve, since the peroneus tertius is a member of the anterior compartment.
3.
Dorsiflexion of the foot : The muscles involved include those of the Anterior compartment of leg, specifically tibialis anterior muscle, extensor hallucis longus muscle, extensor digitorum longus muscle, and peroneus tertius.
4.
The process can begin with swelling of the tibialis anterior, extensor hallucis longus, extensor digitorum longus, and / or the peroneus tertius muscles in response to strong eccentric contractions sufficient to produce postexercise soreness.
5.
The superior extensor retinaculum binds down the tendons of extensor digitorum longus, extensor hallucis longus, peroneus tertius, and tibialis anterior as they descend on the front of the tibia and fibula; under it are found also the anterior tibial vessels and deep peroneal nerve.
