The antagonists to these muscles belong to the quadriceps muscle group, comprised of the rectus femoris
Is the sartorius agonist or antagonist?
Agonists: Hamstrings, Gluteus Medius, Gluteus Maximus. Antagonists : Hip Flexor Group – Iliopsoas, TFL, Rectus Femoris, Pectineus, Sartorius.
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 is the antagonist to the Pectineus?
The Pectineus antagonist is the Gluteus Maximus .
What is the gluteus maximus antagonist?
| Muscle Action Antagonist | Gluteus maximus Hip extension Psoas , Rectus Femoris | Gluteus medius Hip abduction Psoas, Adductors |

What is the function of sartorius?
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. At the hip, it acts to both flex the hip as well as externally rotate.
What does a sartorius strain feel like?
This inflammation may be experienced as pain or hypersensitivity on the inside of the knee[1]. Other symptoms of sartorius-related muscle pain can include a burning or stinging sensation at the front of the hip. This pain may be brought on by an overt trauma, such as an athletic injury.
Can you tear the sartorius muscle?
Most common upper thigh injuries involve the quadriceps muscle group associated with football injuries; however, in rare incidents certain forceful intrinsic injuries can cause intramuscular tear of the sartorius muscle.
Why is the sartorius muscle important?
The sartorius muscle is the longest muscle in the entire human body. ... The sartorius functions as an important flexor and rotator of the thigh at the hip joint . The sartorius muscle arises from the anterior superior iliac spine on the lateral edge of the hip bone.
Is the pectineus an antagonist?
The pectineus is so closely joined with the obturator externus, its antagonist, ( a lateral rotator ) which also originates at the rami of pubis, inserts (although lower) onto the femur, and they are innervated by the same obturator L3 &4 nerves. Yoga Tune Up® has created an arsenal of fix-it postures for myself.
What movement does the Sartorius perform?
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.
What exercise works the Sartorius muscle?
Step-up exercise targets almost all the lower body muscles, especially sartorius. You can do this exercise at a stair, box, or a raised plank. All you need to do is stand with your feet slightly apart in front of a raised plank.
Why are biceps and triceps called antagonistic muscles?
Note: Antagonistic muscles are those muscles, which contract to supply opposite movements at an equivalent joint. ... Biceps and triceps are called antagonistic muscles. Because during flexion at the elbow, biceps contract and triceps relaxes, during extension at an equivalent joint, triceps contract, and biceps relax .
Does every muscle have an antagonist?
| Biceps Triceps | Hamstrings Quadriceps | Gluteus maximus Hip flexors | Gastrocnemius Tibialis anterior | Pectoralis major Latissimus dorsi |

What is the difference between antagonistic and synergistic muscles?
Synergistic muscles are groups of muscles that work together to cause the same movement. Muscles that oppose each other are called antagonistic muscles. Antagonist muscles must oppose the action of an agonist muscle so that movement can occur.
