Popis: During routine anatomic dissection of the lower extremities of a 67-year-old male body, a supernumerary ishiocrural muscle was observed. This supernumerary muscle had similarities to a rare variant of the semimembranous muscle. On the left side it arose from the lateral dorsal side of the femur between the short head of the biceps femoris muscle and the origin of the adductor magnus muscle. It inserted on the medial condyle deep to the normal insertion of the semimembranous at the posterior aspect of the articular capsule. This muscle can be regarded either as a short deep semimembranous muscle (M. semimembranosus profondus) or as a short belly of a semitendinous biceps as known in birds. The muscle was situated closely to the vessels and nerves of the popliteal region. On the right side a similar but somewhat fainter muscle was observed whose origin emanated from the fascia of the adductor magnus muscle. The muscle probably has no major clinical importance but might be important to the surgeon who has to intervene in the popliteal region.
