It is the longest muscle in the human body – is a long thin muscle that runs down the length of the thigh in the anterior compartment. Its upper portion forms the lateral border of the femoral triangle.
It descends as far as the medial side of the knee, passing behind the medial condyle of the femur to end in a tendon.
This tendon curves anteriorly to join the tendons of the gracilis and semitendinosus muscles which together form the pes anserinus, finally inserting into the proximal part of the tibia on the medial surface of its body.
Maybe called the “Tailor's Muscle” because it may refer to the location of the inferior portion of the muscle being the “inseam” or area of the inner thigh tailors commonly measure when fitting a pant or maybe because the muscle resembles a tailor’s measuring ribbon.
