Nerves of Gluteal Region and Posterior Thigh Flashcards
What innervates the skin of the gluteal region?
The superficial gluteal nerves; superior, middle, and inferior clunial nerves
What are the deep gluteal nerves?
Superior and inferior gluteal nerves, pudendal nerve, nerve to obterator internus, nerve to quadratus femoris, posterior cutaneous nerve of the thigh, sciatic nerve
Which nerve does not emerge inferior to the piriformis?
Superior gluteal nerve
What structures does the pudendal nerve supply?
None in the gluteal region, it exits via the lesser sciatic foramen to supply structures in perineum
Which two nerves make up the sciatic nerve?
