Latin: M.. sartorius

  • to the thigh muscles overview
  • to the musculature overview


The tailor's muscle (musculus sartorius) belongs to the group of the anterior thigh muscles. It is approx. 50 cm long and winds helically around the quadriceps. The muscle has functions in the hip joint as well as in the knee joint, whereby the force of the muscle in the hip joint is twice as high as in the knee joint.

Annotation: The term tailor's muscle has nothing to do with sitting cross-legged. The top Adductors and the comb muscle rather produce the cross-legged position.

In leg muscle training, the tailor's muscle is trained by the thigh flexor.
