Three muscles that act synergistically with the rectus femoris are the vastus lateralis, the vastus intermedius, and the vastus medialis. Together the four muscles compose the quadricep muscles of the thigh.
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.
Rectus femoris
rectus femoris
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.

all sports. A "rectus femoris" is a part of your body
the real name is rectus femoris, the vastus muscles are the ones laterally, medially and intermedius, there is no vastus femoris. the Quadriceps Femoris are: rectus femoris, vastus lateralis, vastus medialis and vastus intermedius.
The rectus femoris is found in the middle of the front of the thigh.
Yes the rectus femoris is anterior to the vastus intermedius, vastus intermedius is a deep muscle that we need to cut the rectus femoris in order to see it.
This is the scientific name. Rectus means to be upright, Femoris means pertaining to the femur.
The rectus femoris is one of the quadriceps muscles located on the anterior (front) surface of the thigh.
rectus femoris
the quadriceps which are composed of the rectus femoris vastus lateralis vastus medialis and vastus intermedius.
The rectus femoris becomes active in a leg extension because one of the actions of the rectus femoris is hip extension, as well as knee extension. The rectus femoris crosses both the hip and knee on the anterior side of the body. When the leg is extended it is one of the primary movers, whether it be straight leg extension, in which case it is the rectus femoris, illium and psoas muscles. In knee extension the rectus femoris works in conjunction with the other 3 quadriceps. However, in the case of a seated leg extension the rectus femois is less active, due to it already being shortened for the hip extension.
