What are the funtions of the quadriceps?
Quadriceps contracts to extend the knee joint. Rectus femoris, the part of quadriceps flex the hip joint on the thigh.
Is The antagonist muscle to the quadriceps is the hamstring?
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.
What muscle flexes thigh and extends leg?
The two main muscle groups in the upper leg are the quadriceps which extend your leg and the hamstrings which contract the leg.The biceps femoris, semitendinosus, and semimembranosus.The Hamstring Groupquadraceps and hamstring.Hamstring, biceps femoris, semitendinosus and semimembranosusBiceps femoris, semitendinosus, and semimembranosus.
What is flex and extended?
Muscles that flex the knee are the hamstrings which include your semitendinosus, semimembranosus and biceps femoris musces. Muscles that extend the knee are the quadriceps muscles which includes your vastus lateralis obliques, vastus intermedius, vastus medialis obliques and your rectus femoris.
What leg muscles are similar in function to the triceps and biceps in the arm?
The Quadriceps extend just like the triceps, which include the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. The Hamstrings flex just like the biceps, which include the biceps femoris, semitendinosus, and semimembranosus. Quads extend, Triceps extend Hamstrings flex, arm biceps (biceps brachii, brachialis) flex
What extends the knee and flexes the thigh?
The Femoral nerve. (The motor branches innervate anterior thigh muscles - quadriceps, which flex the thigh and extend the knee.)
What are the three muscles that extend thigh and flex 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.
Extend thigh and flex knee?
Biceps Femoris, Semimembranosus, and Semitendinosus
Paralysis of which muscle would make an individual unable to flex the hip?

Which muscles flex the thigh?
The muscle group is called the Quadriceps
How does the action of the rectus femoris differ from that of the other quadriceps muscles?
This muscle is also used to flex the thigh. The rectus femoris is the only muscle that can flex the hip. Injury to the rectus femoris muscle may result from overuse, as seen with kicking- or sprinting-related injuries. Inflammation of the muscle causes pain in the groin during physical exercises that use this muscle.
