Gemellus InferiorThe structure indicated is the gemellus inferior muscle. The gemellus inferior muscle is one of the muscles of the gluteal region. The muscles in the gluteal region are divided into a superficial and deep group. There are four muscles of the superficial group:
- Gluteus maximus
- Gluteus medius
- Gluteus minimus
- Tensor fasciae latae
- Gemellus superior
- Gemellus inferior
- Quadratus femoris
- Obturator internus
Origin: posterior ischial tuberosity and postero-lateral obturator ring
Insertion: medial surface of greater trochanter of femur
Action: lateral rotation of hip. Assists abduction of hip when hip is flexed.
Innervation: nerve to quadratus femorisLearn more about the anatomy of the gluteal muscles in this tutorial.
