• Sciatic Nerve

• 5.Which nerve exits out the greater sciatic foramen ABOVE thepiriformis muscle?

• 6.What is the most obvious way to differentiate between sciaticnerve and inferior gluteal nerve?

carnival nerve

7. Match the cranial nerves with their associated romannumeral:

CN I CN II CN III CN IV CN V CN VI CN VII CN VIII CN IX CN X CNXI CN XII

Cranial nerves:

A. Vagus nerve
B. Trigeminal nerve
