In this lab, you will investigate the behavior of the human nervous system and make observations of the special senses.
Activity 1: Touch Receptors (worth 10 points total)
List four sensations detected by the tactile receptors in the skin
(1) Temperature
(2) Touch
(3) Pain
(4) Wetness
Get a volunteer to touch each of these locations on your body using the same pressure. Close your eyes and rank how sensitive each area is from 1 (low sensitivity) to 5 (high sensitivity). Put your rankings in the chart.

Answer this question:
What can you conclude about the density of touch receptors in your skin?

Right without glasses: Age 30, 13cm.
Left without glasses: Age 30, 14cm.
How does this compare to your actual age?
It is 15 years ahead of how old I actually am.
Use your notes from this lesson to describe how the eye processes what is sees.
The iris controls how much light is let into an eye, the light is focused onto the lens, and then flipped upside down onto the retina. The retina turns the image you are viewing into a nerve impulse and sends it to the brain where it is then flipped the correct way.
Using what you know about eyesight and image processing, why can age affect the function of the eyes?
Exposure to sun, or mental issues can affect the function of eyes over time.
Activity 3: Hearing and Balance (worth 15 points total)
Label the parts of the ear in the picture. The choices are ear canal, oval window, cochlea, pinna, tympanic membrane, ear ossicles, cochlear nerve, semicircular canals, and Eustachian tube.
(1) Pinna
(2) Ear Canal
(3) Tympanic Membrane
(4) Cochlear Nerve
(5) Oval Window
(6) Cochlea
(7) Ear Ossicles
(8) SemiCircular Canals
(9) Eustachian Tube
