Semitendinosus is a posterior thigh muscle which means that it is located in the posterior compartment of the thigh. So that is the area of the thigh between the buttocks and the popliteal fossa. As we know, in order for muscles to carry out their proper function, there must be a good nerve supply and the semitendinosus is no exception.It is innervated by the tibial nerve. It is the tibial division of the sciatic nerve.

The semitendinosus is actually one of three large muscles located in the posterior compartment of the thigh; the three muscles being the semitendinosus, the semimembranosus and the biceps femoris muscles. These three posterior thigh muscles are also sometimes referred to together as the hamstrings.

The fibers of the semitendinosus muscle originate or have their origin on a palpable protrusion on the surface of the ischium called the ischial tuberosity...and goes on to insert medially on the superior surface of the tibia, just behind the tendon of the gracilis muscle.
