Anatomical terms of muscle

The extensor hallucis brevis is a muscle on the top of the foot that helps to extend the big toe.


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).


Nerve supply: lateral terminal branch of Deep Peroneal Nerve (deep fibular nerve) (proximal sciatic branches S1,S2). Same innervation of Extensor Digitorum Brevis


The extensor hallucis brevis helps to extend the big toe.
