Quadriceps' units and sartorius
The only muscle of the leg that is made up of three muscles are the hamstrings.
Flexing the thigh, extending the leg, adducts leg
extends leg; straightens knee joint
The dorsiflexors include the extensorum longus, the tibialis anterior, and the peroneus.
Tendu is a leg exercise that stretches the leg muscle at you extend it. And degage is the same but a little lift off the floor.
The quadriceps is the large muscle at the front of the thigh, which is divided into four distinct portions and acts to extend the leg.
the muscles that extends the lower leg are vastus lateralis, vastus medialis and vastus intermedius. These muscles collectively make up the quadriceps..
The quadriceps muscle helps straighten and extend the leg and the hamstring helps bend the knee.
Much of the semimembranosus lies deep to the semitendinosus.
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.
The knee helps your leg flex and extend.
The flexor would be the hamstring, and gastrocnemius, which bend/flex the knee. The quadriceps, are extensors, which straighten/extend the knee.
