Abductor hallucis muscle
Abductor Hallucis Muscle
The Abductor Hallucis Muscle (pronunciation: ab-DUK-tor hal-OO-sis MUH-sul) is a muscle located in the foot. It is part of the medial plantar muscles, which are responsible for the movement of the toes and the arch of the foot.
Etymology
The term "Abductor Hallucis" is derived from Latin, where "abductor" means 'to lead away from' and "hallucis" refers to the big toe. Thus, the muscle's function is to move the big toe away from the midline of the body.
Anatomy
The Abductor Hallucis Muscle originates from the heel bone (calcaneus) and the flexor retinaculum. It 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 Abductor Hallucis Muscle is to abduct the big toe, moving it away from the other toes. It also assists in maintaining the arch of the foot and in controlling foot balance during walking and running.
