The artery then descends between the tibialis anterior and extensor digitorum longus muscles.
2.
It passes beneath the tendons of the extensor digitorum longus and fibularis tertius and supplies the lateral side of the ankle.
3.
Blood for the compartment is supplied by the anterior tibial artery, which runs between the tibialis anterior and extensor digitorum longus muscles.
4.
Just below this a part of the extensor digitorum longus takes origin and a slip from the tendon of the biceps femoris is inserted.
5.
Although the anterior tibialis plays a major role in dorsiflexion, it is assisted by the fibularis tertius, extensor digitorum longus and the extensor halluces longus.
6.
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.
7.
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.
8.
The sheath of the Extensor hallucis longus is prolonged on to the base of the first metatarsal bone, while that of the Extensor digitorum longus reaches only to the level of the base of the fifth metatarsal.
9.
It passes forward between the peroneus muscles and the extensor digitorum longus, pierces the deep fascia at the lower third of the leg, and finally divides into a medial dorsal cutaneous nerve and an intermediate dorsal cutaneous nerve.
10.
It arises from the anterior surface of the fibula for about the middle two-fourths of its extent, medial to the origin of the Extensor digitorum longus; it also arises from the interosseous membrane to a similar extent.
