Question

Quizplus · Accepted Answer

The Roman numerals indicate the order in which the cranial nerves exit the brain, with the higher numbered nerves exiting the brainstem further down towards the spinal cord. The designation does not indicate whether the nerves are sensory, motor, or mixed, nor does it indicate specific neurotransmitters used by the nerves. It also does not indicate which nerves emerge from particular lobes of the brain.
