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.
here's a useful mnemonic that I used in medical school:1. Some - olfactory (sensory)2. Say - optic (sensory)3. Marry - oculomotor (motor)4. Money - trochlear (motor)5. But - trigeminal (both)6. My - abducens (motor)7. Brother - facial (both)8. Says - vestibulocholear (sensory)9. Big - glossopharyngeal (both)10. Boobs - vagus (both)11. Matter - accessory (motor)12. More - hypoglossal (motor)
The Optical nerver or the Second Cranial nerve controls and relays information absorbed through the rods and cones of the eye. Eye movements (eye muscles), however, are controlled by several other cranial nerves including the Oculomotor, Abducens, and Trochlear nerves.
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).
The trigeminal nerve is primarily responsible for sensory functions.
The largest sensory nerve of the eye is the optic nerve. It carries visual information from the retina to the brain, allowing us to see and interpret the world around us.
Actually, there are three cranial nerves that are completely sensory: Olfactory nerve, Optic nerve and the Vestibulocohlear nerve. The Optic nerve is responsible for sensory information for vision, the Olfactory nerve is responsible for sensory information coming from the nose and the Vestibulocohlear (the craziest word to spell) involves sensory information for hearing (get it?- cohlear, ear) and equilibrium.
The optic nerve and the auditory nerve are both crucial components of the sensory nervous system, responsible for transmitting sensory information to the brain. Each nerve carries signals from specialized sensory receptors—photoreceptors in the eyes for the optic nerve and hair cells in the cochlea for the auditory nerve. Both nerves play essential roles in enabling perception, with the optic nerve facilitating vision and the auditory nerve facilitating hearing. Additionally, they are both part of the central nervous system pathways that process and interpret sensory stimuli.

Yes, the peripheral nervous system has both sensory and motor nerve cells
