Cranial nerve ganglion

Definition

A cranial nerve ganglion is a collection of nerve cell bodies located outside the brain and spinal cord, associated with the cranial nerves that are part of the peripheral nervous system. These ganglia serve as relay points for transmitting sensory information from the body to the brain and motor commands from the brain to various parts of the body.
