Day 196 - See No Evil, Hear No Evil, Smell No Evil???

(One Day Left - Well, Two...Something Like That)

Since TPTB got our curriculum fouled up last year, we (the graduating students) got separated out from the newbies and we got to learn about the "special senses" such as Eye, Ear, and Nose.
The eye information seemed very familiar to me, so it seemed like a review, but when we got to the ear, I was quite fascinated by how it all works. One of my friends lost her hearing in her adult life and has since had a cochlear implant activated. Now, I can understand what the cochlear implant does, in a rudimentary way, anyway.
It simulates the cochlear part of the inner ear to send the signal to the brain to interpret sound.
Amazing! Rudimentary, but amazing nonetheless!
The inner ear is also the responsible party for maintaining balance and equilibrium. It would make sense, then, that if somebody becomes deaf because of damage to their inner ear, their balance may be thrown off, too.
We also learned a little about the nose and the olfactory sense (sense of smell). The olfactory nerves are found on the ceiling of the nasal cavity and rather than having surrounding tissue, they are out in the open, so to speak.
That made me realize why I felt like my brain was burning when I tried to use the neti-pot with a tiny bit of hydrogen peroxide instead of saline solution. All those nerves got the brunt of the hydrogen peroxide.
Poor babies.
At the end of the lecture, we ended up taking a quiz (10/10) on the information we had just studied. I like that way. Learn it and take the quiz.
As for the next two days, well, what more can be said? Two finals, ring the bell, walk across the stage, and I'm outta there!
