Chapter 5 Flashcards
sensation
sensory information is detected by a sensory receptor
perception
the way sensory information is organized, interpreted, and consciously experienced
subliminal messages
the stimulus no longer needs more energy as the subliminal clues are already in the stimulus to begin with
anatomy of the eye
cornea -> pupil -> lens -> retina/fovea -> optic nerve
cornea
transparent covering of the eye, barrier of the eye from the outside world
pupil
smallest opening in the eye where light passes
iris
determines eye color, colored portion of the eye around the pupil
lens
focus
retina
houses fovea
lens focus imaging happens (synthesizes visual information)
optic nerve
carries visual information from retina to the brain
rods
photoceptors
work in low light conditions
cones
photoreceptors
work in bright conditions, for spatial resolution and color function
anatomy of the ear
outer ear
- pinna
- auditory canal
- tympanic membrane
middle ear
- ossicles
inner ear
- semicircular canals
- cochlea
- basilar membrane
pinna
outer ear
protrudes from head
auditory canal
outer ear
connects outer ear opening to the tympanic membrane
tympanic membrane
outer ear
eardrum, gateway to middle ear
ossicles
middle ear
3 tiny bones
- malleus - hammer
- incus - anvil
- stapes - stirrup
semicircular canals
inner ear
balance and movement
cochlea
inner
snail shaped, filled with fluid
sensory receptor cells and hair cells
basilar membrane
thin strip of tissue within the cochlea that protects hair cells
taste
also: gustation
use of taste buds formed by taste receptor cells on the tongue
smell
also: olfaction
use of olfactory bulbs on the tip of the frontal love, olfactory nerves determines scent of a stimuli
Meissner’s corpuscles
responds to pressure and lower frequency vibrations
vestibular sense
maintain balance and body posture
