In French, a muscle name itself "couturier" comes from this specific position which is referred to as "sitting as a tailor" (in French: "s'asseoir en tailleur"). There are other hypotheses as to the origin of the name.
Where does the Sartorius muscle come from?
The sartorius muscle arises from the anterior superior iliac spine on the lateral edge of the hip bone. From the lateral hip, it descends obliquely across the hip joint and thigh, running medially and inferiorly toward the medial edge of the knee. At the knee, the sartorius turns more laterally as it descends to insert on the medial side ...
What is the function of the Sartorius?
Combining all of these functions into one movement, the sartorius pulls the foot and ankle toward knee of the opposite leg. The action of the sartorius is used in many situations, such as crossing the legs so that the ankle rests on the knee of the opposite leg; sitting cross-legged; or looking at the sole of one’s foot.
Where did Sartorius get its name?
In fact, the name sartorius (from the Latin word for “tailor”) and its nickname, the “tailor’s muscle,” are derived from the common motion of tailors crossing their legs to sit while working.
What is the longest muscle in the human body?

Which muscle is responsible for flexion of the hip and knee joints?
The sartorius muscle crosses both the hip and knee joints, producing movements on both of them. At the hip joint it is capable of flexion, external rotation and abduction of the leg. The contraction of sartorius can also cause flexion of the knee joint and inward, or medial, rotation of the tibia against the femur.
Anatomy
Function
- Since the sartorius muscle is very long and crosses two joints (the hip and the knee) it serves many functions for your body and lower extremities. The movements that the sartorius does are: 1. Flexion of your hip: This means that it bends your hip up as if you were marching. Other muscles, such as your psoasmuscle, also flex your hip up. 2. External rotation of your hip: The s…
Associated Conditions
- Your sartorius muscles may be involved in several different conditions that may limit your functional mobility. These may include: 1. Sartorius muscle strain 2. Tear of the sartorius muscle 3. Pes anserine tendonitis 4. Sartorius paresis or paralysis due to a pinched nerve injuryin your lumbar spine If you have leg pain or weakness, visit your healthcare provider right away to get a…
Rehabilitation
- If you have an injury to your sartorius, you may benefit from working with a physical therapist(PT) during rehabilitation. The treatments you receive from your PT may vary based on your specific injury. These injuries include: 1. Sartorius tendonitis:Tendonitis typically causes pain and limited mobility of the muscle. You may feel pain in the front of your hip while flexing and rotating it duri…
A Word from Verywell
- The sartorius, or tailor's muscle, is the longest muscle in your body and helps you flex and rotate your hip and flex your knee. Having a basic comprehension of the function and location of this important muscle can help you understand your healing and rehabilitation process after an injury.
Overview
The sartorius muscle is the longest muscle in the human body. It is a long, thin, superficial muscle that runs down the length of the thigh in the anterior compartment.
History

This name was chosen in reference to the cross-legged position in which tailors once sat. In French, a muscle name itself "couturier" comes from this specific position which is referred to as "sitting as a tailor" (in French: "s'asseoir en tailleur"). There are other hypotheses as to the origin of the name. One is that it refers to the location of the inferior portio…
Structure
The sartorius muscle originates from the anterior superior iliac spine, and part of the notch between the anterior superior iliac spine and anterior inferior iliac spine. It runs obliquely across the upper and anterior part of the thigh in an inferomedial direction. It passes behind the medial condyle of the femur to end in a tendon. This tendon curves anteriorly to join the tendons of the gracilis and semitendinosus muscles in the pes anserinus, where it inserts into the superomedial …
Function
The sartorius muscle can move the hip joint and the knee joint, but all of its actions are weak, making it a synergist muscle. At the hip, it can flex, weakly abduct, and laterally rotate the femur. At the knee, it can flex the leg; when the knee is flexed, sartorius medially rotates the leg. Sitting cross-legged demonstrates all four actions of the sartorius.
Clinical significance
One of the many conditions that can disrupt the use of the sartorius is pes anserine bursitis, an inflammatory condition of the medial portion of the knee. This condition usually occurs in athletes from overuse and is characterized by pain, swelling and tenderness. The pes anserinus involves the tendons of the gracilis, semitendinosus, and sartorius muscles; these tendons attach onto the anteromedial proximal tibia. When inflammation of the bursa underlying the tendons occurs, the…
