The Hamstrings consist of three muscles that have the same action: the Biceps Femoris, Semitendinosus and Semimembranosus. Their actions are to flex the knee joint, adduct the leg, and extend the thigh.
The Quadriceps femoris is four muscles of the femur. They are the Rectus femoris, Vastus lateralis, Vastus medialis, and Vastus intermedialis. As a group (the quads) they extend the leg at the knee.

The hamstring (back / dorsal side of the thigh)
Quadriceps muscle or thigh muscle.
Quadricepts
hamstring group, made up of semitendinosus, semimembranosus, and the biceps femoris.
The thigh has three sets of strong muscles: the hamstring muscles in the back of the thigh, the quadriceps muscles in the front, and the adductor muscles on the sides.
The general name for the group is hamstring. The technical names of the two primary muscles are semitendinosus and semimembranosus.
The quadriceps muscle helps straighten and extend the leg and the hamstring helps bend the knee.
