Gluteus Medius

The structure indicated is the gluteus medius muscle. The gluteus medius 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:

1. Gluteus maximus
2. Gluteus medius
3. Gluteus minimus
4. Tensor fasciae latae

There are 5 muscles in the deep group:

1. Gemellus superior
2. Gemellus inferior
3. Quadratus femoris
4. Piriformis
5. Obturator internus

Origin: Dorsal ilium inferior to iliac crest

Insertion: Lateral and superior surfaces of greater trochanter

Action: Hip abduction. Hip medial rotation (medial fibres). Hip lateral rotation (posterior fibres)

Innervation: Superior gluteal nerve
