The extensor hallucis brevis is essentially the medial part of the extensor digitorum brevis muscle. Some anatomists have debated whether these two muscles are distinct entities. The extensor hallucis brevis arises from the calcaneus and inserts on the proximal phalanx of the digit 1 (the big toe).
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.
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

The short intrinsic extensors and the plantar and dorsal interossei radiates into these aponeuroses. The extensor digitorum brevis and extensor hallucis brevis have a common origin on the anterior side of the calcaneus, from where their tendons extend into the dorsal aponeuroses of digits 1–4. They act to dorsiflex these digits.
This border gives attachment to an intermuscular septum, which separates the extensor muscles on the anterior surface of the leg from the peronaei longus and brevis on the lateral surface. The antero-medial border , or interosseous crest, is situated close to the medial side of the preceding, and runs nearly parallel with it in the upper third ...
