The quadriceps. They are made of four individual muscles; rectus femoris, vastus intermedius, vastus lateralis, and vastus medialis.

The tensor fascia latae also plays a small role in knee extension.

What is the opposite job of the quadrisepes?

The opposite job of the quadriceps is primarily performed by the hamstrings. While the quadriceps are responsible for extending the knee and are involved in activities like kicking and squatting, the hamstrings are responsible for flexing the knee and extending the hip. These two muscle groups work antagonistically to facilitate movement and maintain balance in the legs.


Does flexing the knee increase the use of the biceps femoris?

Yes, flexing the knee increases the activation of the biceps femoris, which is one of the muscles that make up the hamstrings. As the knee flexes, the biceps femoris contracts to help bend the knee and stabilize the joint. This muscle plays a crucial role in movements involving knee flexion, such as running or cycling.

The sartorius is a long, thin muscle located in the thigh. It runs from the hip to the knee, crossing over the front of the thigh, and is involved in actions like flexing, abducting, and laterally rotating the hip, as well as flexing the knee. It is often referred to as the "tailor's muscle" because its actions are similar to the position a tailor assumes while sitting cross-legged. This muscle is the longest in the human body.
