The question is asking what three cranial nerves are purely sensory in their function. Some relevant terms here are olfactory, optic, and auditory or vestibucochlear or acoustic nerves. The only three cranial nerves that are pure sensory in function are cranial nerve #1 : the olfactory nerve (smell), cranial nerve #2 : the optic nerve (sight), and cranial nerve #8 : the auditory/vestibucochlear/acoustic nerve (hearing).
Somatic sensory nerve impulses get to the brainstem from the head itself via the cranial nerves. Cranial nerves are also known as cerebral nerves.
Sensory neuron
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.

what does ninth cranial nerve control? glossopharyngeal nerve is a mixed nerve, it has sensory and motor part. the sensory is at the poserior 1/3 of the tongue. It also is part of the pharyngeal plexus. (9,10,11) The motor part of the nerve ONLY supply the stylopharyngeus muscle!
A sensory neuron transmits a nerve impulse towards the central nervous system. These nerve cells activated by input, transmits sensory information.
Trigeminal neuralgia is a rare disorder of the sensory fibers of the trigeminal nerve (fifth cranial nerve), which innervate the face and jaw. The neuralgia is accompanied by severe, stabbing pains in the jaw or face.
