Is the optic nerve a sensory or motor nerve?

In: Eyes and Vision Disorders [Edit categories]

Answer:

The optic nerve is a cranial nerve (CN II) that sends special somatic afferent (sensory) fibers to the lateral geniculate of the thalamus. Here, they synapse and continue via optic radiations to the primary visual cortex of the brain.

The motor portion of the eye is controlled by cranial nerves as well only they are: Oculomotor (CN III), Trochlear (CN IV), and Abducens (CN VI); there is also some sympathetic innervation (not from cranial nerves) that cause pupillary dialation.
