The Extensor Hallucis Brevis arises from the calcaneus and attaches on the 1st proximal phalanx or the big toe where it help extend the big toe.

The Extensor Hallucis Longus starts at the anterior surface of the Fibula and also attaches below on the 1st Proximal Phalanx or big toe and helps extend it, but also causes dorsiflexion of the foot and ankle.
