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)
Cranial nerve I (Olfactory), II (optic), and VIII (Vestibulocochlear).
Olfactory Nerve.
1, 2 and 8
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).
no
Mixed nerve is a nerve that carry all the motor function, sensory function and the autonomic function in a single fiber. Spinal nerve is the example of the mixed nerve. Some of the Cranial nerve on the other hand is not the mixed nerve as it only has one property which is either sensory or motor function. http://www.answers.com/main/ntquery?s=spinal+nerve&gwp=13
vagus
Somatic sensory nerve impulses get to the brainstem from the head itself via the cranial nerves. Cranial nerves are also known as cerebral nerves.

Cranial nerve II
sensory nerve
no
Trigeminal. Sensory function- touch/temp/pain. Motor function-chewing. Branches-mandibular, maxillary and opthalmic.
eight

I- Olefactory (sensory): smell. II- Optic (sensory): vision.

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!
