On the medial side of the thigh, the adductor magnus muscle takes the form of a large triangle. As an adductor, it contracts and pulls the hip towards the body's midline. This action is a fundamental part of walking, sprinting and a host of other bipedal motions. The muscle also extends the hip. Also, the muscle is often considered part of the two muscular groups. While an adductor, the muscle is often considered part of the hamstring as well. The muscle originates in the pelvic region; specifically, it arises from the pubis and the tuberosity of the ischium. Then, the muscle inserts into several parts of the femur bone. Oxygenated blood arrives at the adductor magnus muscle via the obturator artery, which branches from the internal iliac artery. Once blood is deoxygenated, the obturator veins drain into the venal system. For adductive motion, innervations come by way of the inferior branch of the obturator nerve. For hamstring functions, the muscle is served by the sciatic nerve.
