ATTACHMENTS:

  • The sartorius attaches from the ASIS to the pes anserine tendon at the proximal anteromedial tibia.

 

ACTIONS:

  • The sartorius flexes, abducts, and laterally rotates the thigh at the hip joint.
  • It anteriorly tilts, depresses, and contralaterally rotates the same-side pelvis at the hip joint.
  • It also flexes the leg (and/or thigh) at the knee joint.

 

NOTES OF TRIVIA:

  • The sartorius is the longest muscle in the human body.
  • It crosses the hip joint anteriorly but crosses the knee joint posteriorly.
  • It is nicknamed “the tailor muscle” (sartorius means tailor in Latin).
