    upper three fourths of the external surface of the shaft of the femur. The muscle is inserted along with the rectus femoris. Vastus Interims takes its origin from the anterior intertrochanteric line, from the upper half of the internal surface of the shaft of the femur, and from the upper three fourths of the anterior surface of that bone. The fibres blend with those of the preceding muscle, and are inserted along with those of the next muscle. Rectus Femoris arises from the inferior border of the iliac bone im- mediately in front of the acetabulum. Its fleshy fibres pass downwards, and terminate in a tendon common to it and the two preceding muscles. This tendon is inserted into the anterior tubercle of the tibia, it receives on its outer side some of the fibres of the long vastus, and on its inner those of the long adductor of the leg. Internal Femoral Region. Short Adductor of the Leg (Gracilis).—Has an extensive origin from the lower surface of the pubic bone close to the symphysis, and from a median tendinous band which separates it from the opposite muscle. This band extends back as far as the anus. The muscle is inserted by means of a broad aponeurotic tendon, the upper half of which is attached to the inner border of the tibia, whilst the lower half unites with the fascia cover- ing the inner head of the gastrocnemius. Pectineus arises from the inferior border of the pubis close to the gra- cilis. It passes downwards, and winds round the middle of the femur to be inserted into the posterior border of the shaft of that bone. Adductor Femoris arises from the outer surface of the body of the pubis, between the origins of the pectineus and semi-membranosus, and is inserted into the posterior border of tbe femur, its insertion corresponding to that of the pectineus, but extending a little further down. Posterior Femoral Region. Semi-membranosus arises from the external surface of the pubic arch, its origin extending from the posterior extremity of the symphysis to the tuberosity of the ischium. Its insertion is into the lower third of the in- ternal condyloid line of the femur, into the internal lateral ligament of the knee-joint, and into the internal tuberosity of the tibia. Semitendinosus.—This muscle arises, together with the vastus longus, from a special tubercle of the ischium below the tuberosity of that bone, as well as from the tuberosity itself, and from the upper border of the ischium. The fibres form a thick fleshy mass, which lies parallel to the posterior border of the vastus longus, and is inserted beneath the gracilis into the inner border of the upper part of the shaft of the tibia, and also into the fascia covering the gastrocnemius.
