Anatomical terms of muscle

The abductor hallucis muscle lies along the medial border of the foot and covers the origins of the plantar vessels and nerves.

It arises from the medial process of the tuberosity of the calcaneus, from the laciniate ligament, from the plantar aponeurosis, and from the intermuscular septum between it and the flexor digitorum brevis.

The fibers end in a tendon, which is inserted, together with the medial tendon of the flexor hallucis brevis, into the tibial side of the base of the first phalanx of the great toe.

It is responsible for abducting the great toe.

Innervation[edit]

Abductor hallucis is innervated by the medial plantar nerve.

Variations[edit]

Slip to the base of the first phalanx of the second toe
