The oblique and transverse heads of the adductor hallucis of the foot on the right side of the body.

The Adductor Hallucis is an intrinsic muscle of the foot located in Plantar Layer III. The muscles located in Plantar Layer III are:


The adductor hallucis has two heads: Oblique Head and Transverse Head.



  • Metatarsals to the big toe (toe #1).
    • The oblique head attaches proximally onto metatarsals #2-4 and the distal tendon of the fibularis longus.
    • The transverse head attaches proximally into plantar metatarsophalangeal ligaments.
    • The distal attachment of the adductor hallucis is onto the lateral side of the base of the proximal phalanx of the big toe.



  • Adducts the big toe at the metatarsophalangeal joint.
  • Flexes the big toe at the metatarsophalangeal joint.



  1. A tight (overly facilitated) adductor hallucis can contribute to hallux valgus, known in lay terms as a bunion.
  2. There is an adductor pollicis muscle in the hand that has two heads: oblique head and transverse head.
