Adductor Magnus Muscle

The adductor magnus is the long, triangular muscle which is located on the medial aspect of the thigh. It arises from the ischial tuberosity and ischiopubic ramus, with insertion to the linea aspera and femur. The adductor magnus is innervated by a branch of the obturator nerve and the sciatic nerve and is supplied by the obturator artery. The proximal portion of the adductor magnus rotates the thigh medially and flexes it on the hip, while the distal portion extends the thigh and rotates it laterally. The hamstring portion is often considered part of the hamstring group of muscles.
