The adductor longus is one of the three adductor muscles of the thigh. Being the most superficial of the three, the adductor longus overlaps the adductor brevis and partially covers the adductor magnus; it is also one of five medial femoral muscles. The adductor longus arises from the symphysis and crest of the pubis, with insertion to a ridge on the shaft of the femur. It is innervated by the anterior branch of obturator nerve and is supplied by the obturator artery. Functions: draws inward toward the median axis of the body and flexes the thigh.
