Semitendinosus Tendon

Last Updated: Jun 23, 2015

The semitendinosus tendon is one of the hamstring muscles. It is a long, band like muscle on the back of the thigh toward the inside, connecting the ischium to the proximal end of the tibia. It is so named because it becomes tendinous in the middle of the thigh, continuing to its movable end as a long, cordlike tendon. It functions to flex and rotate the leg medially and to extend the thigh.
