This muscle varies considerably in the modes of origin and the arrangement of its various tendons. The tendons to the second and fifth toes may be found doubled, or extra slips are given off from one or more tendons to their corresponding metatarsal bones, or to the short extensor, or to one of the interosseous muscles.
Extensor hallucis longus: Middle part of anterior surface of fibula and interosseous membrane: Dorsal aspect of base of distal phalanx of great toe (hallux) Extends great toe and dorsiflexes ankle Extensor digitorum longus: Lateral condyle of tibia and superior three quarters of medial surface of fibula and interosseous membrane
Occasionally united at its origin with the extensor digitorum longus.. The extensor ossis metatarsi hallucis, a small muscle, sometimes found as a slip from the extensor hallucis longus, or from the tibialis anterior, or from the extensor digitorum longus, or as a distinct muscle; it traverses the same compartment of the transverse ligament with the extensor hallucis longus.
A compartment space is anatomically determined by an unyielding fascial (and osseous) enclosure of the muscles.The anterior compartment syndrome of the lower leg (often referred to simply as anterior compartment syndrome), can affect any and all four muscles of that compartment: tibialis anterior, extensor hallucis longus, extensor digitorum longus, and peroneus tertius.

Foot drop is rarely the result of a pathology involving the muscles or bones that make up the lower leg. The anterior tibialis is the muscle that picks up the foot. Although the anterior tibialis plays a major role in dorsiflexion, it is assisted by the fibularis tertius, extensor digitorum longus and the extensor hallucis longus.

The muscles end in tendons, which pass forward on the medial sides of the four lesser toes, and are inserted into the expansions of the tendons of the extensor digitorum longus muscle on the dorsal surfaces of the proximal phalanges. [1]
