 THE TENSOR FASCIA LATAE IS A MUSCLE OF THE THIGH LOCATED IN THE LATERAL ASPECT OF THE THIGH. TENSOR FASCIA LATAE IS A FUSIFORM MUSCLE AND TOGETHER WITH GLUTEAL MAXIMUS IT ACTS ON THE ILIOTIBIAL BAND AND   IS CONTINUOUS WITH ILIOTIBIAL TRACT AND ATTACHES TO THE TIBIA. ORIGIN:  ILIAC CREST(POSTERIOR TO ANTERIOR SUPERIOR ILIAC SPINE) INSERTION:  ILIOTIBIAL TRACT (WHICH CONTINUES TO ATTACH TO THE LATERAL CONDYLE PF THE TIBIA) NERVE SUPPLY:  SUPERIOR GLUTEAL NERVE BLOOD SUPPLY: PRIMARILY LATERAL CIRCUMFLEX FEMORAL ARTERY,SUPERIOR GLUTEAL ARTERY ACTION:  PREVENTS COLLAPSE OF EXTENDED KNEE IN AMBULATION,ASSIST ABDUCTION,MEDIAL ROTATION,FLEXION OF FEMUR AT HIP AND EXTENSION OF KNEE. PALPATION: BELOW SUPERIOR ILIAC SPINE ON ANTERIOR PELVIS (AT A LEVEL OF GREATER TROCHANTER)DURING ACTIVE HIP ABDUCTION. THIS MUSCLE BRACES THE KNEE WHEN WALKING. ALSO KNOWN AS ILIOTIBIAL BAND(ITB).  

Agonist Muscle these are chief muscles , which produces the main movement. it is also called as prime movers as they are initiative muscles for the action. there are many muscles are in the body which is acting as prime movers. but as for example, we take the flexors of the elbow to understand this concept. elbow flexion is done by brachialis as well as biceps brachii muscles. no doubt both muscles are needed to do elbow flexion but the brachialis has its major function into elbow flexion. so here brachialis is the agonist muscle for the elbow flexion. Antagonist :  I am against the  agonist , so I am famous as antagonist woohoo!😏 antagonist's muscles are acting against the agonist. for the example, we take the elbow flexion and extension. as we know  biceps brachii  and  brachialis  is acting together as an  agonist for elbow flexion,  here the  extensor muscles  of the elbow the  triceps is antagonist's muscles. this both agonist and antagonist's muscles work u
