    synaptic vesicle release. (Please remember the retrograde messenger
    is theoretical, I just thought it should be included here)

## Senses

### Critical Thinking: Vision

1\. Explain why you are normally unaware of your blind spot.

:\*Since your eyes are looking from different angles, they see each
other\'s blind spot and your brain combines the two images.

2\. Stare at a bright light for 10 seconds and then stare at a white
sheet of paper. What do you observe and why?

:\*You should observe a negative afterimage. This happens when the
rod/cone (mostly cone) cells in your eye adapt to the stimulus and lose
their sensitivity, leaving you with the negative of the color that was
adapted to.

3\. What is it that makes things \"disappear\" when you are staring at
them at night, and how do you make them reappear?

:\*There are no rods in the fovea, so little light is picked up when you
stare directly at the object. To make it reappear, just don\'t look
right at it.

4\. Name what rods are sensitive to and also what cones are sensitive
to.

:\*Rods are more sensitive to lower light levels, but lack color-seeing
ability. Cones work in brighter light and perceive color (blue, green,
red).

5\. Explain how Deadly Nightshade works

:\*Normally, the parasympathetic nervous system constricts the pupil as
needed with acetylcholine. The atropine in nightshade is a competitive
agonist on the same receptor as the one that accepts acetylcholine.
Basically: the atropine takes up all of the places for acetylcholine to
bind, and the pupils dilate.

### Critical Thinking: Hearing

1\. Explain how the pitch of sound is coded. How is the loudness of
sound coded?

2\. What do the three semicircular canals in the inner ear enable us to
do? How do they accomplish this?

:\*Each of the three fluid filled canals is on a different plane.
Movement is detected on these planes when the fluid inside moves around,
vibrating cilia on the cupula which sends it on to the brain.

3\. What does the eustachian tube do? What does the eustachian tube have
to do with a middle ear infection?

:\*The eustachian tube is to keep pressure in the middle ear the same as
atmospheric pressure. If the tube is blocked, the gases in the ear will
diffuse back into the surrounding tissues and a vacuum will be made.
Eventually, this will pull fluid in and if it becomes infected\... You
have an ear infection.

4\. What is the advantage of having a oval window?

Sound transducted from air to a more dense medium (endolymph, in scala
media where the organ of cortis is placed) would be partially reflected
and greatly weakened if not for the ossicular bones that transfer the
vibration from membrana tymphani trough malleus, incus and stapes to the
foramen ovale where it puts the liquids of cochlea in motion. This
motion is then transfered trough membrana vestibularis to membrana
basilaris, which in turn puts the haircells in motion. This leads to a
bending of the stereocills, fastened to membrana tectori, and as a
result; a depolarization of the afferent sensory fibre receptor of n.
cochlearis through release of glutamate. The loss of energy in
transduction is partially re-gained by the size of membr. tympani
compared to the size of foramen ovale and the rotation of the ossicular
bones.
