Olfaction is the sense of smell.
The Olfactory System is the sensory system used for Olfaction (smelling).
So in short, Its a sensory system (nerve) not a motor nerve.
Think of motor nerves as nerves that cause a change in something, such as muscle motor nerves cause the muscle to contract.
Sensory Nerves 'sense' the environment around them and then transfer this information on to other parts of the body such as the brain.
The receptor that received motor nerve and sensory nerve
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.
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 sensory receptors for the eyes are the optic nerve and the retina. The sensory receptor for the nose are the olfactory nerves.
Sensory neuron
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).
its both motor and sensory
it is sensory
sensory nerve
to transfer nerve impulses to the brain
Yes, the peripheral nervous system has both sensory and motor nerve cells
The Olfactory nerve. CN1 Cranial Nerve I, or the first cranial nerve called the Olfactory nerve.
