Sartorius: ribbons, records and tailors
What is it? A long, flat muscle running down the length of the front part of the thigh like a ribbon. It travels diagonally, from the top of the outer side of the pelvic bone, across to the tibia bone, to just under the inner side of the knee. Why is it a record breaker? It’s the longest muscle in the body— researchers in Brazil dissected the sartorius out of a number of dead people and found it had an average length of 45cm. What does it do? It helps us cross our legs by bending our hips and rotating them outwards, while also bending our knees. What’s it got to do with tailors? It was named because of the cross-legged position in which tailors traditionally sit while working. Sartor is Latin for mender, and sartorial in English is the adjective pertaining to tailors.
