Anatomy Didactic Week 6 - posterior thigh and gluteal
region



1. how does the gluteal region communicate with the pelvic cavity and perineum: greater sciatic
foramina
lesser sciatic foramina

2. what is main role of deep gluteal muscles, and what muscles make it up: to rotate thigh - 6 short rotators
1. pirformis
2. obturator internus
3. gemellus inferior
4. superior gemellus
5. quadratus femoris
what is the 6th? it is not part of the gluteal region - obturator externus)

3. what muscles are in superficial gluteal group

what motion do they all do: gluteus maximus, medius, and minimus, and tensor fascia lata


abduct hip

4. what structures pass through the greater sciatic foramen?: - superior gluteal vein, artery, nerve
- piriformis
- sciatic nerve
- inferior gluteal vein, artery nerve
- pedendal nerve, interpedendual vein and artery
- posteriorfemoral cutaneous nerve

+ nerves to the
