E2 auditory and vestibulatr

Question 1

frequency

Answer 1

number of cycles per second
pitch
20 to 20kHz

Question 2

cycle

Answer 2

1 compression and 1 rarefaction

Question 3

amplitude

Answer 3

loundess of sound

measure of pressure difference from peak compression to rarefaction

Question 4

external ear

Answer 4

aurical/pinnna
external auditory canal
tympanic membrane

Question 5

middle ear

Answer 5

3 osscile - malleus, inucs, stapes

auditory/eustachian tube to throat

Question 6

inner ear

Answer 6

cochlea
vestibule
semicicular canales

Question 7

impedance matching

Answer 7

stapes pushing oval windowo to amplifiy between air to fluid

Question 8

tensor tympani and stapedius muscle

Answer 8

CN V and CN VII

stiffen to decrease transmission in response to loud noise

Question 9

oval and round window

Answer 9

oval transmits from stapes to cochlea, round moves in opposite direction because perilymph is incombressible so fluid can move

Question 10

bony vs membraneous labrythng

Answer 10

peri vs endolymph

Question 11

scalas vestibuil, media, tympani

Answer 11

oval windo to vestibuli to helicotrema to tympanai to round window with perlymph
scala media inside with endo lymph and hair cells and tectorial and basal membranes and hair cells

Question 12

reissners embrane

Answer 12

separates scala vestibuili from scala media

Question 13

basilar membrane

Answer 13

separate scala tympanie from scala media
has organ of corti on its surface
narrow base for high frequencies
wide apex for low frequencies
max amplitude at appopriate frequency spot

Question 14

utircule and saccule

Answer 14

have hair cells in the otolithic membrane with otoltihs hat move in response to linear acceleration and gravity

Question 15

utricle

Answer 15

horizontal plane

toward striola

Question 16

saccule

Answer 16

gravity plane

away from stiola

Question 17

semicircular canals

Answer 17

angular accelaration
3 orthogonally oriented
ampula with hair cells in the crista and sterocillia in the cupula
filled with endolymph
endolymph moves in opposite direction of head moving hair cells with it
