Q

aka hair cells

A

stereocilia

24

inner hair cells are in blank rows and transmit signals to blank

A

one, auditory nerve

25
Q

outer hair cells have blank rows and are for blank

A

three, electromotility

26
Q

hearing loss due to hair cells or auditory nerve fiber damage

A

sensorineural

27
Q

hair cell physical mechanical wave bends stereocilia which causes blank of ion channel

A

depolarization

inner hair cells synapse with blank percent of auditory nerve fibers

A

90%

30

outer hair cells synapse with blank percent of cochlear nerve fibers

A

10%

31
Q

reflexive contraction of middle ear muscles to dampen loud sounds

A

acoustic reflex pathway

32
Q

descending auditory pathway projection that is control over the initiation of auditory signals… may dampen your own voice to protect your hearing

A

olivocochlear bundle

33
Q

semicircular canals

A

ampulae

34
Q

blank and blank do linear acceleration

A

utricle, saccule

35
Q

crystals in utricle and saccule

A

otoconia

36
Q

otoconia can fall into blank

A

posterior canal

37
Q

when otoconia fall into posterior canal

A

benign proxysmal positional vertigo

38
Q

vestibular system is most important for blank

A

balance/posture/proprioception

39
Q

head moves one way, eyes move other direction

A

vestibulo ocular reflex

40
Q

part of central focus in macula

A

fovea

41
Q

macular degeneration damages blank

A

fovea

42
Q

part of retina where axons of eye leave to get to the brain

A

blind spot

43
Q

visual system blank electromagnetic stimuli into an electrial signal/nerve impulses

A

transduces

44
Q

brain turns nerve impulses into blank

A

perceptions

45
Q

two types of photoreceptors

A

cones, rods

46
Q

peripheral vision uses blank mostly which are good in dim light

A

rods

47
Q

color vision in fovea

A

cones

48
Q

rods (rhodopsin) blank when light hits them which creates a signal

A

break apart, (opsin +retinal)

49
Q

three cell layers of retina

A

photoreceptor, bipolar, ganglion

50
Q

nasal hemiretina crosses at the blank

A

optic chiasm

51
Q

two types of retinal ganglion cells

A

parvocellular, magnocellular

52
Q

retinal ganglion cells that are small and near fovea for color

A

parvocellular

53
Q

retinal ganglion cells that are large, in periphery, and for motion

A

magnocellular

54
Q

there is blank of magnocellular and parvocellular layers

A

segregation

55
Q

each layer gets input from blank eyes

A

one

56
Q

cortex located in occipital lobe and surrounds calcarine fissure

A

primary visual cortex

57
Q

cortical pathway that is input from magnocellular and parvocellular… what an object is…color

A

ventral stream

58
Q

cortical pathway that is the “where” or “how”… movement… and is mostly magnocellular input

A

dorsal stream
