The Sartorius Muscle, also know as “The Tailor’s Muscle” is the longest muscle in the human body. There are three hypotheses as to the genesis of the name “The Tailor’s Muscle”: One is that this name was chosen in reference to the cross-legged position in which tailors once sat. Another is that it refers 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. A third is that the muscle closely resembles a tailor’s ribbon. Thanks to my med-student friend Beth for introducing me to the bodies most “fashionable” muscle!
