Rectus femoris muscle

The rectus femoris (Latin for " straight muscle of the thigh " ) is one of the anterior muscles of the thigh. He is a head of the quadriceps femoris ( " four -headed thigh muscle "). In the tendon of this muscle, the patella is embedded as a sesamoid bone. Patellar ligament About the tendon is finally attached to the tibial tuberosity of the tibia and forms the approach of the muscle.

The rectus femoris originates proximal to the rectum Caput inferior to the ventral side of the anterior iliac spine. In addition, there is a caput reflexum which is inconstant detectable and rises at Margo superior of the acetabulum.

Function

The rectus femoris stretches along with the other heads of the quadriceps femoris, radiate their tendons in the common tendon, the knee joint. Imbalances of these muscles, such as paralysis, practice cross forces on the kneecap, which can lead to habitual dislocation of the patella.

In addition, the rectus femoris flexes the hip joint and acts in raising the extended leg. However, it did not develop as much force as the state of the diffracted knee. In the case of muscle is more biased and operates in the most efficient portion of its stroke.

Rectus femoris as food

The rectus femoris is one of the few muscles, which constitute an anatomically accurate flesh part of the domestic pig, the nut. It is used either as a roast or smoked as Nussschinken.
