Fig. 67.—Deep Dissection of the Medial Aspect of the Thigh. the transverse process of second (possibly also the first) coccygeal vertebra and the edge of the sacro-tuberous ligament, passes over the sciatic tuber, beyond which it joins the larger main head. A synovial bursa may intervene between the muscle and the tuber. The short tendon of insertion of the semimembranous is attached to the medial epicondyle of the femur and the medial collateral ligament of the femoro-tibial joint, along with part of the insertion of the adductor, while beyond this it becomes continuous with the fascia of the leg.
