The Adductor hallucis (Adductor obliquus hallucis) emerges by 2 heads– oblique and transverse and is in charge of adducting the big toe. It has 2 heads, both are innervated by the lateral plantar nerve.
The oblique head is a big, thick, fleshy mass, crossing the foot obliquely and inhabiting the hollow area under the very first, 2nd, 3rd and 4th metatarsal bones.
It emerges from the bases of the 2nd, 3rd, and 4th metatarsal bones, and from the sheath of the tendon of the Peronaus longus, and is inserted, together with the lateral part of the Flexor hallucis brevis, into the lateral side of the base of the very first phalanx of the big toe.
The transverse head (Transversus pedis) is a narrow, flat fasciculus which occurs from the plantar metatarsophalangeal ligaments of the 3rd, 4th, and 5th toes (in some cases just from the 3rd and 4th), and from the transverse ligament of the metatarsals.
It is inserted into the lateral side of the base of the very first phalanx of the fantastic toe, its fibers mixing with the tendon of insertion of the oblique head.
