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.
Extension of the knee joint occurs when the quadriceps femoris muscles contract. This movement straightens the leg by increasing the angle between the thigh and the lower leg.
The quadriceps muscle covers the front of the thigh, while the adductor muscles cover the inner thigh and the abductor muscles cover the outer thigh.
The two anterior aspects of the upper thigh are the quadriceps femoris muscle group and the sartorius muscle. The quadriceps femoris group is a large muscle that covers the front of the thigh and is responsible for extending the knee joint. The sartorius muscle is the longest muscle in the body and helps with flexing the hip and knee joints and rotating the thigh.
The common name for rectus femoris is the quadriceps muscle. It is one of the four muscles in the quadriceps group located in the front of the thigh.
Quadriceps=4 heads Femoris= Upper leg Quadricepts femoris= 4 muscles of the upper leg.
There are 4 groups in the quadriceps femoris muscle.
In Latin quadriceps means four heads, and the quadriceps femoris muscle has four parts called heads.
There are 4 parts in the quadriceps femoris muscle, hence the name.

The only one that comes to mind is the thigh muscle which is called the quadriceps femoris (quads) and is composed of 4 portions: Rectus femoris Vastus lateralis Vastus medialis Vastus intermedius
Quadricepts
The quadriceps femoris muscle.
The quadriceps femoris group extends the leg at the knee joint. It is responsible for straightening the knee and kicking movements.
The patella is embedded in the tendon of the quadriceps muscle, specifically in the tendon of the quadriceps femoris. It acts to protect and provide leverage for this muscle during movements like running and jumping.
Quadriceps contracts to extend the knee joint. Rectus femoris, the part of quadriceps flex the hip joint on the thigh.
