The Magic Southwestern Airlines Boeing 737 pt.3
Storyboard Text
- Mr. Johnson, where to now?
- Yeah, what's this long stringy thing?
- This, children, is the optic nerve! We are following it to the thalamus!
- The Thalamus is the central routing system of the brain. Consider it the post office! All mail has to go through the post office before it can reach its final destination, therefore the optic nerve sends its impulse to the thalamus which goes to the visual cortex to be processed.
- So... what else is there to know?
- Ah, yes! Color is absorbed through the receptors in our eyes. You see, color is formed by lights, objects absorb certain light and reflect all others, which is the light we perceive.
- How do we see colors?
- Sound Waves
- Auditory Canal
- Eardrum
- Bones of the middle ear
- So now lets see what all of these parts do!
- Semicircular canals
- Oval window
- Auditory Nerve
- Cochlea
- SOUND WAVES: Vibrations in the air entering the ear. AUDITORY CANAL: Canal that connects the other ear to the middle ear. EARDRUM: A thin cone shaped membrane. OVAL WINDOW: Membrane covered opening that leads to inner ear. COCHLEA: Produces nerve impulses in response to sound vibrations. AUDITORY NERVE: Nerve fibers carrying info between cochlea and the brain. SEMICIRCULAR CANALS: 3 fluid filled boney channels in the inner ear. Provides info about orientation and maintains balance. BONES OF THE MIDDLE EAR: Ossicles, malleus, incus, and scapes.
- I'm guessing that the cochlea sends its nerve impulse message through the auditory nerve, which then makes its way to the auditory cortex for processing?
- Well... yeah.
