The "hamstrings" or semimembranosus and semitendinosus muscles.
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 quadriceps femoris is a group of four muscles located on the front of the thigh that work together to extend the knee and flex the hip. These muscles are important for activities like walking, running, and jumping.
