Although the adductor magnus muscle is not a muscle of the posterior compartment, part of its fibers parallel the course of the hamstring muscles and should be studied at this time. Identify the fibers of the hamstring portion of adductor magnus muscle [the probe indicates the adductor magnus muscle; the retractor holds the semimembranosus muscle]. These fibers arise from the ischial tuberosity. Distally, this portion of the adductor magnus muscle inserts into the adductor tubercle of the medial condyle of the femur. For review, the hamstring portion of the adductor magnus muscle is innervated by the sciatic nerve. The adductor portion of the adductor magnus muscle is innervated by the obturator nerve.
