15


15. What makes up the superficial layer of gluteal muscles? What is their action?

Gluteus maximus
Gluteus medius
Gluteus minimus

Mostly extensors and abductors of thigh

16. For the gluteus maximus give the origin and insertion

Origin – sacrotuberous ligament, ilium (posterior to posterior gluteal line), sacrum and coccyx
Insertion – gluteal tuberosity and iliotibial tract

17

17. For the gluteus maximus give the action, nerve, and blood vessels

Action: Extension and lateral rotation of thigh
Rising from sitting
Nerve: Inferior gluteal
Blood: Superior and inferior gluteal arteries

18

18. Give the gluteus medius’ origin and insertion

Origin – ilium between anterior and posterior gluteal line
