What Are the Hamstring Muscles? The hamstring muscles are a group of three muscles located on the back of your thigh. The three muscles are called the biceps femoris, the semimembranosus, and the semitendinosus. These three muscles work together to help bend your knee.
Semimembranosus and Semitendinosus. Two of the hamstring muscles -- the semimembranosus and semitendinosus -- lie on the inner side of the back of your thigh. Both muscles originate from the sitting bone, or ischial tuberosity, on the back of the pelvis.emimembranosus and Semitendinosus.
