The adductor magnus muscle is the largest of three adductor muscles arising from the pelvic bones and inserting on the femur. In this case, the adductor magnus is split into two divisions, the adductor portion and hamstring portion. The adductor powerfully adducts the hip, while the hamstring portion of the adductor magnus rotates the leg medially. Generally, adductor muscles move a limb toward the central line of the body or a digit toward the axis of a limb. It comes from the Latin word, adductus, meaning one that draws to.
