The Hamstring muscles flex the knee. There are 3 of them
Semimembranosus: is the most superficial (closest to the surface), found on the medial (inner) side of the back of the thigh.
Semitendonosus: is found underneath semimembranosus
Biceps Femoris: is found on the lateral (outer) side of the back of the thigh. Attaches to the fibula and outside of the tibia

It is the rectus femoris, which along with the action of knee extension, it also flexes the hip
