Semimembranosus.—The semimembranosus arises by a tendon from the superior and lateral facet on the ischial tuberosity (Figs. 366, p. 412, and 374, p. 419). In the proximal third of the thigh the tendon gives place to a rounded fleshy belly, which lies be- neath the ischial origin of the biceps and semitendinosus muscles. Becoming tendinous at the back of the knee, it is inserted into the horizontal groove on the postero- medial aspect of the medial condyle of the tibia (Figs. 376, below, and 384, p. 428). A bursa lies deep to the tendon at its insertion. It has three additional membranous inser- tions : (1) a fascial band extends distally and medially to join the posterior border of the tibial collateral ligament of the knee-joint; (2) an- other fascial band extends distally ADDUCTOR MAGNUS Semitendinosus Semimembranosus Sartorius tendon.
