Sartorius Muscle

DEFINITION – What does Sartorius mean?

Notably the longest of all the human body’s muscles, the Sartorius is a long, narrow muscle that runs superficially along the entire length of the thigh in the forward compartment. Originating from the forward superior iliac spine, it travels obliquely across the thigh passing to the rear of the femur’s medial condoyle, ending in a tendon that curves back to where it connects with the tendons of the Semitendinosus and Gracilis muscles of the pes anserinus, and finally inserts into the tibia.

FUNCTION – Sartorius Muscle

A synergist type muscle, the Sartorius is unable to perform tasks requiring brute strength. While it is able to move both the hip and knee joints, it does so weakly, flexing, abducting, and rotating the thigh, and flexing and rotating the leg. Sartorius receives its control from the femoral nerve.
