Etymology

The name sartorius is the Latin word for "sartorial" (i.e. "to do with tailoring", in turn from sartor i.e. "tailor", in turn from sartus i.e. "patched" or "repaired", in turn from sarcio i.e. "to patch", "to repair"). Latin is an ancient Indo-European language originally spoken in Latium, the region immediately surrounding Rome. ...

This name was chosen in reference to the cross-legged position in which tailors once sat.

Action

The action of sartorius is to cross the legs, by flexion of the knee, and flexion and lateral rotation of the hip. Sartorius does not have a very strong action.

Innervation

Situated in the anterior fascial compartment of the thigh, sartorius is innervated via branches of the femoral nerve. Cross-section through the middle of the thigh. ... The Femoral Nerve supplies innervation the anterior portion of the leg. ...

Variations

The term Illion, Ilium has several meanings, including in legends, in anatomy, and in the arts: Ilion or Ilium is an alternative name for the legendary city of Troy. ...

Common Injuries of the Sartorius Muscle
