Anatomical terms of muscle

The Adductor hallucis (Adductor obliquus hallucis) arises by two heads—oblique and transverse and is responsible for adducting the big toe. It has two heads, both are innervated by the lateral plantar nerve.

It evolved from the contrahens I muscle as Man's ancestors' thumbs and big toes became opposable.


Oblique head[edit]

The oblique head is a large, thick, fleshy mass, crossing the foot obliquely and occupying the hollow space under the first, second, third and fourth metatarsal bones.

It arises from the bases of the second, third, and fourth metatarsal bones, and from the sheath of the tendon of the Peronæus longus, and is inserted, together with the lateral portion of the Flexor hallucis brevis, into the lateral side of the base of the first phalanx of the great toe.

Transverse head[edit]

The transverse head (Transversus pedis) is a narrow, flat fasciculus which arises from the plantar metatarsophalangeal ligaments of the third, fourth, and fifth toes (sometimes only from the third and fourth), and from the transverse ligament of the metatarsus.

It is inserted into the lateral side of the base of the first phalanx of the great toe, its fibers blending with the tendon of insertion of the oblique head.


Slips to the base of the first phalanx of the second toe. Opponens hallucis, occasional slips from the adductor to the metatarsal bone of the great toe.



The 'English' name adductor hallucis muscle is partly Latin, i.e. adductor hallucis and partly English, i.e. muscle. The full Latin expression as used in the current edition[1] of the official Latin nomenclature (Terminologia Anatomica) is musculus adductor hallucis.

In classical Latin hallex,[2][3] allex,[2][4] hallus [2] and allus,[2] with genitive (h)allicis and (h)alli, are used to refer to the big toe. The form hallux (genitive, hallucis) currently in use is however a blend word of the aforementioned forms.[2][5] Musculus adductor hallicis[6] is used instead by some.
