The largest of the hamstring (caudal thigh) muscles is the biceps femoris m. (1) which originates from the ischium and inserts broadly on fascia lata (2) and crural fascia (3). The muscle has been transected in two locations to facilitate reflecting it. The semitendinosus m. (4) is partially exposed.
Other visible (non-hamstring) muscles include: sartorius m. (5), tensor fasciae latae m. (6), middle gluteal m. (7), superficial gluteal m. (8), levator ani m. (9), and external anal sphincter m.(10).
