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 cranial nerve is totally sensory in function?
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)
Which cranial nerves carries only sensory information?
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).
Which cranial nerve is used in reading the paper?
The main nerve required would be the optic nerve (II), although you would also use the ocular motor nerve (III) to move the eyes. Other cranial nerves involved are: Trochlear nerve (IV) and Abducens nerve (VI).
Mixed nerve house?
Both sensory and motor neurons...
A mixed nerve contains which type of nerves?
a mixed nerve carry both motor and sensory nerves
Which carnial nerves are purely sensory?
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.
Is vagus nerve a motor nerve?
its both motor and sensory
What is the the first pair of the cranial nerve?
