adductor hallucis muscle adductor hallucis 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. adductor hallucis musclemuscles of the sole of the foot. third layer.
