Sartorius
Sartorius
Sartorius (/sɑːrˈtɔːriəs/), is a long, thin, superficial muscle that runs down the length of the thigh in the anterior compartment. It is the longest muscle in the human body.
Etymology
The name Sartorius comes from the Latin word "sartor", which means tailor. It is sometimes referred to as the "tailor's muscle" due to the cross-legged position in which tailors once sat.
Anatomy
The Sartorius muscle originates from the anterior superior iliac spine and part of the notch between the anterior superior iliac spine and the anterior inferior iliac spine. It runs obliquely across the upper and anterior part of the thigh in an inferomedial direction. It then descends to insert into the upper part of the medial surface of the tibia.
Function
The Sartorius functions as an important flexor and rotator of the thigh at the hip joint. The muscle's long length allows it to work over both the hip and knee joints.
