quadriceps femoris
The quadriceps femoris is a large muscle group located at the front of the thigh. It consists of four individual muscles: the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. This group is primarily responsible for extending the knee joint, which is essential for activities like walking, running, and jumping.
In addition to knee extension, the quadriceps femoris plays a role in stabilizing the knee and supporting the hip joint. Strengthening these muscles can improve athletic performance and reduce the risk of injuries. Regular exercises, such as squats and leg presses, can help maintain their strength and function.
