Definition
Noun: A long, thin, strap-like muscle located in the anterior compartment of the human 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 at work, hence its common name.
