The quadriceps sounds like it should be just one muscle, akin to the triceps brachii, but it is a group of four muscles, three visible on the surface, and the fourth obscured.

The three surface muscles of the quadriceps are the rectus femoris in the center, the vastus medialis on the medial side, and the vastus lateralis on the lateral side. These three muscles are visible in Figure Below the rectus femoris and largely hidden by it is the vastus intermedius. The four muscle of the quadriceps all extend the lower leg, and the rectus femoris additionally can flex the thigh at the hip. The quadriceps group of four muscles.
