That would be the rectus femoris.
Quadriceps femoris
Joint. A muscle must cross a joint to move the insertionbone relative to the bone of origin. For example, the biceps spanning the elbow joint and the quadriceps spanning the knee joint.
The leg curl is a muscular resistance exercise that primarily works the quadriceps. It involves the knee joint and develops strength in the quadriceps at the front of the thigh.
The patella: 1- Increases the lever arm of the quadriceps muscle in its function to extend the knee joint. 2- Redirect the forces exerted by the quadriceps muscle.
Why do all muscle cross a joint? Define the attachment points of muscle to bone?
Quadriceps contracts to extend the knee joint. Rectus femoris, the part of quadriceps flex the hip joint on the thigh.
The quadriceps muscle helps straighten and extend the leg and the hamstring helps bend the knee.
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.
It crosses the ankle joint and may be subtalor joint.
If you're talking about moving the joint, either the muscle or the tendon does. There are plenty of muscles that aren't involved with a joint, such as the heart muscle, facial muscles, stomach and intestines...
Rectus femoris Vastus medialis Vastus intermedialis Vastus lateralis Sartorius
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.
