Eye and ear anatomy questions?

Sensory cells in the _____are stimulated when movement of the head causes endolymph to move.

----I was thinking semicircular duct or vestibule for this one, but as I am reading about it, it's telling me about hair. This lesson is on senses.

I think semicircular duct Vestibular System: Structure and Function (Section 2, Chapter 1

What about this one?

The cerebellum coordinates balance, posture, and smooth body movements. To perform this function it receives information from.....

I put.....

1)Cerebral cortex

2)Sensory neurons

3)Spinal cord

4) Brain stem

(I need 4)

I'm attempting to help, but I should state that I'm a pre-nursing student.

Heres the first couple....
Sensory cells in the _____are stimulated when movement of the head causes endolymph to move.
----I was thinking semicircular duct or vestibule for this one, but as I am reading about it, it's telling me about hair. This lesson is on senses.
Hmm the endolymph acts on the ampullary cupula, which bends the cilia on the hair cells.
______is the term used to describe the type of receptors that generate action potentials resulting in the perception of gustation and/or olfaction.
----I put olfactory receptors...but we have learned about lots of other receptors like chemoreceptors, nociceptors, photoreceptors....and so on.
I think olfactory is correct
Where must sensory information go to have perception?
---Well since perception is the ability to see, hear, or become aware of something through senses, I was thinking about somewhere in the brain stem or one of the brain lobes....but the question below threw me off.
The parietal lobe? Sensory cortex?
What happens if sensory information ends in the brain stem or thalamus?
-----Honestly, not sure if this is a bad idea that it ends up there, but I know that the thalamus is a center for pain perception
Well, sensory information has to pass through the thalamus on its way to the somatosensory cortex, right? So if it stops in the brain stem or thalamus I feel like that would lead to no conscious perception of stimuli
List 2 sensory madalities that have little or no adaptation?
---well I know that smell and hearing we can adapt to after smelling or hearing something for a good amount of time....so would like thought be one we can't adapt to? Not sure about this one.

I know that specific structures adapt at different paces - like Merkel discs and Ruffini corpuscles - maybe that's an answer?

The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements.

I have one question that I am currently stuck on.....

The spread of the action potential in nerves is commonly called the________?

I said nerve impulse but that doesn't sound right. Any other ideas? Or is it depolarization, resting membrane, or stimulus?
