How are cranial nerves named?
The numbering of the cranial nerves is based on the order in which they emerge from the brain and brainstem, from front to back. The terminal nerves (0), olfactory nerves (I) and optic nerves (II) emerge from the cerebrum, and the remaining ten pairs arise from the brainstem, which is the lower part of the brain.

What are the 12 cranial nerves and their uses?
How are cranial nerves named and numbered?
Cranial nerves are named based on their structure or function. For example, the olfactory nerve (I) relays smell, while the facial nerve (VII) relays motor functions to the face. The cranial nerves are numbered in order from front to back within the brain. < Structure and Function of the Cerebellum > Suggested Reading.
