What is the sartorius muscle?
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 rehab should you suffer an injury to it.

What is Sartorius tendonitis?
Sartorius Tendonitis: This condition typically results in pain and limited mobility of the muscle. Many people feel pain in the front of their hip while flexing and rotating it during walking. Your PT may help decrease the inflammation of the muscle and help improve its ability to contract properly to help you regain normal walking and movement.
What happens if you tear your sartorius muscle?
Sartorius Tear: A tear to the sartorius may involve a significant period of immobility and rest to allow for the muscle to heal. Once healing has taken place, your PT may work with you to improve scar tissue mobility, improve sartorius muscle flexibility, and improve strength of the muscle.
What causes weakness in the sartorius area?
Weakness in the sartorius due to nerve injury: If you have a condition with your low back like a herniated disc or spinal foraminal stenosis, nerve compression may occur. This pinched nerve may cause pain and weakness in the front of your thigh, and your sartorius may be affected.
What is the antagonist muscle of the sartorius muscle?
Antagonist: Gluteus maximus, Adductor magnus (posterior part).May 11, 2020
Is the sartorius agonist or antagonist?
Agonists: Hip flexor group - Iliopsoas, TFL, Rectus Femoris, Pectineus, Sartorius. Antagonists: Hamstrings, Gluteus Medius, Gluteus Maximus.May 10, 2017
What is the synergist muscle for sartorius?
During lateral rotation of the hip, the sartorius is a synergist to the gluteus maximus, obturator internus and externus, gemelli, quadratus femoris and the piriformis.
Which muscle is an antagonist to the rectus femoris?
The hamstringsThe hamstrings are the antagonist muscles to the rectus femoris. They produce the opposite action.Jun 30, 2020
What is the antagonist of the Popliteus?
The popliteus has some function in knee flexion, but more importantly, as an internal rotator of the tibia. The antagonists to these muscles belong to the quadriceps muscle group, comprised of the rectus femoris, vastus medialis, vastus lateralis, and vastus intermedius, all of which act to extend the knee.

What is the gracilis antagonist?
Function Extension of the thigh at the hip Agonists: gluteus maximus, semimembranosus, biceps femoris (long head), and adductor magnus (posterior part) Antagonists: psoas major and iliacus The semitendinosus is also a weak medial rotator of the hip.

What is the antagonist of the deltoid?
The middle region of the deltoid muscle is the prime mover for arm abduction. The pectoralis major acts as an antagonist to the middle deltoid anteriorly, whilst the latissimus dorsi acts as the antagonist posteriorly.
What is the antagonist of quadriceps femoris?
The muscle group antagonist to the quadriceps femoris group is the hamstring group including the biceps femoris, semitendinosus, and semimembranosus....
What is the function of the Sartorius muscle?
The sartorius muscle acts synergistically in concert with the other musculature of the hip, thigh, and knee. Structure and Function. The function of the sartorius is unique in that it can serve as both a hip and knee flexor. The origin for the sartorius is the anterior superior iliac spine, sharing this origin with the tensor fascia lata.
Where is the Sartorius muscle located?
It is the most superficial muscle in the anterior compartment of the thigh and travels obliquely from the anterior superior iliac spine (ASIS) to the medial side of the proximal tibia at the pes anserine. The sartorius muscle acts synergistically in concert with the other musculature of the hip, thigh, and knee. Structure and Function.
What is the longest muscle in the body?
The sartorius is the longest muscle in the body, spanning both the hip and the knee joints. The word sartorius is derived from the Latin word sartor, which translates to patcher, or tailor, due to the way the individual will position their leg while working.
Which muscle group is derived from the anterior division of the femoral nerve?
Posterior division, motor: Quadriceps muscle group (rectus femoris, vastus medialis, vastus lateralis, vastus intermedius) The innervation to sartorius is derived explicitly from the anterior division of the femoral nerve. The posterior division supplies innervation to the muscles of the quadriceps. The pectineus nerve innervates the pectineus, ...
Where does the blood supply to Sartorius come from?
The blood supply to sartorius is mostly comprised of muscular branches of the femoral artery. Over half of the blood supply comes from these muscular branches of the femoral artery, but collateral flow does come from elsewhere.
Which rotator acts in concert with the sartorius?
Along with the popliteus as mentioned above, other internal rotators of the knee acting in concert with sartorius include the semimembranosus, semitendinosus, and gracilis. These muscles are opposed by the long and short heads of the biceps femoris, which act to rotate the knee externally.
Which rotator is the antagonist of the hip?
Antagonists and external rotators of the hip include the piriformis, both the superior and inferior gemelli, both the obturator internus and obturator externus, and the quadratus femoris. [1] The insertion for the sartorius muscle is the superior medial aspect of the tibial shaft, near the tibial tubercle.
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 heal...
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.
