Hallucis brevis muscle (shown in red)

The Hallucis brevis muscle is a small muscle located in the human foot. It is one of the intrinsic muscles of the foot, meaning it is entirely contained within the foot and does not extend to any other part of the body.

Anatomy

The hallucis brevis muscle originates from the cuboid bone and the lateral cuneiform, and inserts into the medial side of the base of the proximal phalanx of the big toe. It is innervated by the medial plantar nerve, a branch of the tibial nerve.

Function

The primary function of the hallucis brevis muscle is to flex the big toe at the metatarsophalangeal joint. This action is important for maintaining balance while standing and walking.

Clinical significance

Damage or injury to the hallucis brevis muscle can result in a loss of balance and difficulty walking. It may also cause hallux valgus, a condition characterized by a lateral deviation of the big toe.
