Superior gemellus muscle

The superior gemellus muscle is a muscle of the human body.
The Gemelli are two small muscular fasciculi, accessories to the tendon of the Obturator internus which is received into a groove between them.
The Gemellus superior, the smaller of the two, arises from the outer (gluteal) surface of the spine of the ischium, blends with the upper part of the tendon of the Obturator internus. In some people, the fibres of the gemellus superior extend further than average, and are prolonged onto the medial surface of the greater trochanter of the femur.
