Q

what is the pupil

A

the small adjustable opening in the center of the eye

20
Q

what is the lens

A

the transparent structure behind the pupil

21
Q

what is hyperopia

A

farsighted vision problems

22
Q

what is color-blindness caused by

A

a defect in cones

23
Q

young-heimholtz trichromatic theory

A

the retina contains 3 different types of cones which when stimulated in combination can produce any color

24
Q

opponent-process theory

A

theory that cones are paired together to enable color vision, activation of one color of the pair inhibits activation of the other color

25
Q

motion parallex

A

when an object appears to move faster if it is closer to you than if it is farther away (car on highway vs plane)

26
Q

retinal disparity

A

depth perception cue, occurs because your eyes dont see identical fields of vision

27
Q

what is the low frequency (ear)

A

the low pitch wavelength

28
Q

what is the high frequency (ear)

A

the high pitch wavelength

29
Q

what is the low amplitude (ear)

A

quiet

30
Q

what is the high amplitude (ear)

A

loud

31
Q

what parts make up the outer ear

A

the auditory canal

32
Q

auditory canal

A

funnels sound waves from the pinna to the eardrum

33
Q

what parts make up the middle ear

A

the tympanic membrane (eardrum) and ossicles

34
Q

tympanic membrane (eardrum)

A

thin layer of tissue that vibrates in response to sound waves

35
Q

ossicles

A

transfer the sound waves from the eardrum to the oval window

36
Q

what are the 3 bones of the middle ear

A

the incus, malleus and stapes

37
Q

what parts make up the inner ear

A

the oval window, cochlea, basilar membrane and auditory nerve

38
Q

oval window

A

the opening of the cochlea that vibrates when it receives the sound waves and causes the fluid inside the cochlea to move

39
Q

cochlea

A

the coiled, bony, fluid-filled tube containing semicircular canals, the fluid vibrations trigger nerve impulses

40
Q

basilar membrane

A

overlays the cochlea, ripples cause haircells to vibrate, this is where transduction occurs

41
Q

auditory nerve

A

carries neural impulses to thalamus-> temporal lobe

42
Q

whats the mnemonic device for hearing path

A

Americans Eat Octopus On Coastal Beaches (Always)

43
Q

sensorineural

A

damage to the cochleas hair cell receptors or the auditory nerve, people may hear sound but have trouble discerning what someone is saying

44
Q

conduction

A

damage to the mechanical system- eardrum and middle ear bones

45
Q

frequency theory

A

when the basilar membrane vibrates in synchrony with the pitch (wavelength)

46
Q

place theory

A

each area along the basilar membrane is tuned to a specific frequency of a sound wave

47
Q

mnemonic device for light path

A

can people let reindeer outdoors
