Tensor fasciae latae muscle

The flat, rectangular tensor fasciae latae (Latin for leg bandages tensioner or thigh binding tensioner ) is a skeletal muscle of the lower extremity, specifically the posterior ( dorsal) layer of the posterior hip muscles. In evolutionary terms, it is a spin-off of the central buttock muscle ( gluteus medius ) dar.

Course

The leg binding tensioner originates at the ilium ( ilium ), more precisely from the anterior superior iliac spines ( anterior superior iliac spine ) and radiates in a strip-shaped reinforcement ( iliotibial band or Maisiatscher strips ) of muscle binding ( fascia ) of the thigh ( fascia lata ) a.

With this reinforcement strips of muscle between the patellar ligament is ( patellar ligament ) and head of the fibula ( fibular head ) at the lateral condyle ( the condyle ) to the shinbone (tibia ) to ( lateral condyle of the tibia ).

Function

The leg binding tensioner is not a very powerful muscle. Mainly he straddles the fascia lata and its reinforcement strips (supporting the tension band ).

The muscle also contributes to the diffraction (flexion ) of the knee joint. With the knee in extension thus the train the muscle has a stabilizing effect.

Due to its location above the diffraction or stretching axis he is - despite its small physiological cross-section - a powerful flexors ( flexor ) in the hip joint and, for example, sprinters pronounced. Furthermore, the muscle can support pronation ( internal rotation ) and Abspreizbewegung (abduction ) of the femur.
