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.

Which muscle is not a member of the hamstring?

The muscle that is not a member of the hamstring is the quadriceps. The hamstring group consists of the biceps femoris, semitendinosus, and semimembranosus muscles, which are located at the back of the thigh and are primarily responsible for knee flexion and hip extension. In contrast, the quadriceps, located at the front of the thigh, are responsible for knee extension.

Why is biceps femoris is the antagonist muscle in knee extension?

The biceps femoris is one of the hamstring muscles located at the back of the thigh, and its primary function is to flex the knee and extend the hip. During knee extension, the quadriceps muscles contract to straighten the leg, while the biceps femoris must relax to allow this movement to occur. Hence, it acts as an antagonist to the quadriceps during knee extension, opposing their action and facilitating smooth movement.
