What are spinal nerves?

PNS nerves that originate from the spinal chord (Cranial nerves are nerves that start in the brain)

Check

What is the difference between depolarization and repolarization

depolarization- Na channels open in response to a stimulus. Na rushes into the cell. Repolarization -Na channels close and K rush out of the cell.
