1. Additionally, with the hip flexed, the gluteus medius and minimus internally rotate the thigh. 2. With the hip extended, the gluteus medius and gluteus minimus externally rotate the thigh. 3. A part of the gluteus medius arises from this membrane. 4. Additionally, with the hip flexed the gluteus medius and minimus internally rotate the thigh. 5. With the hip extended, the gluteus medius and gluteus minimus internally rotate the thigh. 6. They are the gluteus maximus, gluteus medius and gluteus minimus-commonly known as the buttock muscles. 7. Hip abduction is performed primarily by the hip abductors ( gluteus medius and minimus ). 8. The posterior fibres of gluteus medius contract to produce hip extension, lateral rotation and abduction. 9. The gluteus medius will become weak and inhibited. 10. When the hip adductors are tight or hypertonic, their antagonist ( gluteus medius ) may experience reciprocal inhibition.
