Definition

1. Noun:
   • The sartorius muscle is a long, thin, superficial muscle located in the anterior compartment of the thigh. It is the longest muscle in the human body. Its primary actions are to flex, abduct, and laterally rotate the thigh at the hip joint, and to flex the leg at the knee joint. This combination of movements assists in crossing the legs, a posture historically associated with tailors (sartors) at work, which is the origin of its name.

Usage Examples

• Noun:
  • The sartorius muscle runs diagonally across the front of the thigh from the hip to the inner knee.
  • An injury to the sartorius muscle can cause pain when climbing stairs or sitting cross-legged.
