The quadriceps muscles of the anterior compartment of the thigh are responsible for the action of extending the knee. The quadriceps are actually four muscles all working together. They consist of the rectus femoris, the vastus lateralis, the vastus medialis, and the vastus intermedius.They are all monoarticulate, except the rectus femoris which is diarticulate, which means that it acts on two joints.

Muscle group extends the thigh and flexes the knee?
The general name for the group is hamstring. The technical names of the two primary muscles are semitendinosus and semimembranosus.
What three muscle extends the thigh and flexes the knee?
The muscle of the thigh are classified into three groups, anterior group, posterior group, and interior or adductors group. There are four muscle on the anterior group - quadriceps femoris- and their function is to extend the knee or extend the thigh depend on what part of the muscle don't move. Those muscle are the rectus femorarlis, vastu intermedius, vastu medialis, and vastus lateralis. The muscle that flex the knee are located on the back of the thigh and form the posterior group. They are the biceps femoris, semitendinousus, and the semimembranosus, better known as Hamstring.

Extends the thigh and flex the knee?
The primary muscle responsible for extending the thigh is the quadriceps femoris, specifically the rectus femoris. To flex the knee, the primary muscles involved are the hamstrings, particularly the biceps femoris, semitendinosus, and semimembranosus. These muscle actions are important for movements like running and kicking.
What is the antagonist muscle in the flexion of the knee?
The antagonist muscle in the flexion of the knee is the quadriceps muscle group. When the knee is being flexed, the quadriceps relax to allow the hamstrings to contract and bring about the flexion movement.
