sound waves cause apical specialization (stereocilia and kinocilia) to _____________________
deform
26
____channels located at their base are opened to allow influx which causes signaling cascade
ion
27
3 components of vestibular apparatus
utricle saccule semicircular canals
28
linear acceleration/gravity
utricle
29
vertical acceleration/gravity
saccule
30
angular acceleration/ movement of head
semicircular canals
31
detects changes in a horizontal plane
utricle
32
detects changes in a vertical plane
saccule
33
relays angular acceleration/movement
semicircular canals
34
Have vestibular hair cells which operate similar to auditory hair cells
inner ear
35
vestibular hair cells are deformed by displacement of _____ w/in gelatinous matrix
otoconia
36
also known as ear stones, are calcium carbonate crystals in the inner ear that help you sense balance and acceleration
otoconia
37
in the utricle and saccule, neurosensory area where vestibular hair cells are found
macula (B)
38
in semicircular canals, neurosensory area where vestibular hair cells are found
crista ampullaris (C)

41
meningioma
42
pontocerebellar angle tumor
43
made up of antoni A w/ verocay bodies and and antoni B (hypocellular)
schwannoma
44
vibrations (sound waves) from external environment are translated into neural code by traveling through _____
ECOLIMA
45
ECOLIMA:
E: eight cranial nerve (hair cells) C: cochlear nucleus O: Olivary complex L: lateral lemniscus I: inferior colliculus M: medial geniculate nucleus A: auditory cortex
46
once signals from auditory pathway enter the CNS, projections are sent ____
bilaterally
47
main auditory pathway (contralateral)
cochlea CN VIII cochlear nuclei olivary nuclei lateral lemniscus inferior colliculi medial geniulate body auditory cortex
48
minor auditory pathway (ipsilateral)
cochlea CN VIII cochlear nuclei olivary nuclei lateral lemniscus inferior colliculi medial geniculate body
49
2 categories of hearing loss
conductive sensorineural
50
hearing loss in outer or middle ear
conductive
51
hearing loss that deals with inner ear or CNS pathway
sensorineural
52
age-related loss of hair cells; starts at base of cochlea (20,000 Hz) and migrates to apex (20 Hz) Hearing aids can help compensate for high frequencies
Presbycusis
53
uses bone conduction of sound to help localize laterality
Rinne and Weber test
54
test that deals with conduction
Rinne
55
test that deals with localization
Weber
56
air > bone midline
no hearing loss
57
air > bone Weber test + in normal ear
sensorineural
58
bone > air weber test + in affected ear
conductive
59
amplifies sound we are receiving
hearing aid
60
actually stimulates hair cells with a device through implanted receiver
cochlear implant
61
Excessive exposure to sound Ototoxic antibiotics Chemotherapeutics (e.g., cisplatin)
common causes of hearing loss
62
safe exposure limit
85 decibels/8 hrs a day
63
Sensation of spinning while stationary
vertigo
64
most common cause of vertigo
BPPV (peripheral cause)
65
central vertigo cause
brainstem lesion
66
peripheral vertigo causes
BPPV meniere
67
Disorder characterized by episodes of vertigo triggered by changing head position (otolith displacement into semicircular canals)
