Sar­to­rius: rib­bons, records and tai­lors

The Weekend Australian - Travel - - Health -

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.
