The large adductor muscle (m.adductor magnus) is thick, triangular in shape. It begins on the sciatic hillock, the branch of the ischium and on the lower branch of the pubic bone. It is attached throughout the medial lip of the rough line. It is located behind the short and long conducting muscles. Behind her are the tendon, semimembrane muscles and the long head of the biceps femoris. The bunches of the proximal part of the muscle are oriented almost horizontally, extending from the pubic bone to the upper body of the thigh. Bunches of the distal part of the muscle are directed vertically downwards - from the ischial to the medial epicondyle of the thigh. The tendon of the large adductor muscle at the attachment site to the adductor tuberculum adductorium of the femur limits the hole called the tendon slit (hiatus tendineus adductorius). Through this gap the femoral artery from the leading canal to the thigh passes into the popliteal fossa. Near the artery lies the femoral vein.
Function of the large adductor muscle: is the strongest adductor muscle of the thigh; medial muscle bundles, originating in the ischium, are also involved in the extension of the thigh.
Innervation of the large adductor muscle: blocking (LII-LIII) and sciatic (LIV-LV) nerves.
Blood supply to the large adductor muscle: blocking and perforating arteries.
