What is the sartorius muscle?
The sartorius muscle is a thin, long, superficial muscle in the anterior compartment of the thigh. It runs down the length of the thigh, runs over 2 joints—hip and knee joints and is the longest muscle in the human body. An exceptional length of this muscle often exceeds 50cm.
What is Sartorius tendinopathy?
If the bursa underlying the tendons of the sartorius, gracilis, and semitendinosus gets irritated from overuse or injury, a person can develop this ailment. This condition usually occurs in athletes from overuse and is a common cause of chronic knee weakness and pain. It is characterised by pain, swelling and/or tenderness.
What causes pain in the sartorius tendons of the knee?
If the bursa underlying the tendons of the sartorius, gracilis, and semitendinosus gets irritated from overuse or injury, a person can develop this ailment. This condition usually occurs in athletes from overuse and is a common cause of chronic knee weakness and pain.
Is sartorius an antagonist or agonist?
Agonists: Hip flexor group - Iliopsoas, TFL, Rectus Femoris, Pectineus, Sartorius. Antagonists: Hamstrings, Gluteus Medius, Gluteus Maximus.
What muscle is synergist to 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. During knee flexion (bending), it assists the hamstring complex (semitendinosus, semimembranosus, and biceps femoris).
What muscle attaches to the sartorius?
The insertion for the sartorius muscle is the superior medial aspect of the tibial shaft, near the tibial tubercle. Two other tendons join it at its insertion: the gracilis and semitendinosus, to create the conjoined tendons known as the pes anserinus. At the knee, it acts to flex as well as internally rotate.
What is sartorius innervated by?
the femoral nerveIn addition to flexing the hip and knee, the sartorius aids in the abduction of the hip. It is innervated by the femoral nerve (i.e., the posterior division of L2 and L3).
Which muscles are antagonists?
Examples of Antagonistic MusclesBiceps and triceps.Gluteus maximum and hip flexors.Hamstrings and quadriceps.Pectoralis major and latissimus dorsi.Gastrocnemius and tibialis anterior.Abductor and adductor.
What are synergist and antagonist muscles?
Following contraction, the antagonist muscle paired to the agonist muscle returns the limb to the previous position. Synergist muscles act around a movable joint to produce motion similar to or in concert with agonist muscles, allowing for a range of possible movements.
What is the sartorius action?
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.
Why is sartorius called honeymoon muscle?
Originally Answered: Why is Sartorius known as the honeymoon muscle? It is called so because it causes abduction and lateral rotation at hip joint which would be a critical action for all the action that is required during the Honeymoon. It causes opening of thigh and flexibility of thighs.

Is the sartorius Biarticular?
The sartorius muscle is a biarticular muscle. It is the only muscle of the thigh which bends both hip joint and knee joint. It initialises the movement of flexion in both joints from the phase of full extension, while other flexors need its initial flexion as an initial position to begin a movement [8].

Is the sartorius muscle voluntary or involuntary?
But like smooth muscles, they are involuntary, controlled by the autonomic nervous system. The longest muscle in the human body is the sartorius (pronounced sar-TOR-ee-us). It runs from the waist down across the front of thigh to the knee. Its purpose is to flex the hip and knee.
Description
Etymology
- Sartorius derives from the Latin word sartor, meaning tailor, and it is occasionally referred to as the tailor's muscle.This name was chosen in reference to the cross-legged position in which tailors once sat.
Variation
- There are slight adaptive ethnic differences in width and the range of muscle belly and tendon of the sartorius muscle.The muscle may be absent in some people.
Blood Supply
- The muscle receives 5 to 11 vessels originating from: superficial circumflex iliac, lateral femoral, deep femoral, descending geniculate, and femoral arteries.
Function
- At the hip it flexes, weakly abducts, and rotates the thigh laterally.At the knee, it can flex the leg; when the knee is flexed, it also rotates the leg medially. This muscle plays an important part in stabilisation of the pelvis—especially in women.This is due to the constrictive effect which the muscles on both sides of the body have on the pubic symphysis.
Clinical Significance
- The Pes anserinus refers to the conjoined tendons of the gracilis, semitendinosus and the sartorius. It lies superficial to the tibial insertion of the medial collateral ligament of the knee. Pes anserine bursitis is a condition in which the medial portion of the knee is inflamed. If the bursa underlying the tendons of the sartorius, gracilis, and ...
