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

Structure

The extensor hallucis brevis is essentially the medial part of the extensor digitorum brevis muscle. Some physiologists 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).

Innervation

The extensor hallucis brevis is innervated by the deep fibular nerve (deep peroneal nerve).

Action

The extensor hallucis brevis helps to extend the big toe.

The term Iliopsoas refers to the combination of three muscles:
  • psoas major
  • psoas minor
  • iliacus
These muscles are distinct in the abdomen, but in the thigh, they are usually indistinguishable, and so in that context, they are usually given a common name.
