|
operate through sensory receptor cells that receives external forms of energy and translates these external forces into neutral impulses that can be transmitted to the brain. |
Sense organs |
|
|
five types of Sense organs: |
-see -hear -smell -touch -feel |
|
|
anything capable of exciting a sensory receptor cell |
stimuli |
|
|
translating messages into the brains language |
Transduction |
|
|
sense organs transduce...
|
sensory energy into neural (bioelectrical) energy |
|
|
converting one type of energy into another type |
process of tranduction |
|
|
constructed of wave/particles packets of energy called photons |
light |
|
|
only a tiny part of the much broader electromagnetic spectrum |
visible light |
|
|
light is measured by its... |
intensity an frequency |
|
|
the transduction of light wave/particles into neural energy is carried out by the receptor cells in the.. |
retina of the eye |
|
|
the retina has 2 general types of cells that engage in transduction |
rods and cones |
|
|
black and white light (peripheral) |
rods |
|
|
colored light |
Cones |
|
|
the clear outer covering of the eye |
Cornea |
|
|
a colored circular muscle |
iris |
|
|
part of the that focuses on an object |
lens |
|
|
opening of the eye |
pupil |
|
|
white of the eye, protective |
sclera |
|
|
back of the eye that has receptor for light |
retina |
|
|
transmits visual information from the retina to the brain. |
optic nerve |
|
|
Cones: Red, Green, Blue -red cones detect red, blue cones detect blue, ect.. |
the trichromatic theory |
|
|
- 3 cone type (similar to tichromatic theory) but each of the three have opponent processes (unlike trichromatic theory) -red-green cones,blue-yellow cones, and black and white cones |
the oppenent-process theory |
|
|
human eyes and the brain work together. each eye's retina picks up a pattern from the light which is sent through the optic nerve to the brain |
Stereoscopic vision |
|
|
the sense that detects vibratory changes in the air called sound waves |
hearing |
|
|
changes in the air pressure |
sound waves |
|
|
measure by their frequency and amplitude |
sound waves |
