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:

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