Abductor hallucis muscle
Muscles of the sole of the foot. First layer. (Abductor hallucis visible at center left.)
The plantar arteries. Superficial view. (Abductor hallucis visible at center left.)
Latin	musculus abductor hallucis
Gray's	subject #131 491
Origin	tuberosity of the calcaneus
Insertion	medial aspect of base of 1st phalanx of hallux
Artery
Nerve	Medial plantar nerve
Actions	abducts hallux
Antagonist	Adductor hallucis muscle

The Abductor hallucis 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.
