top of antihelix

Question 10

external acoustic meatus

Answer 10

ear hole

Question 11

tympanic membrane

Answer 11

flap at end of ear hole

Question 12

middle ear

conducts sound

Question 13

auditory ossicles

Answer 13

malleus, incus, stapes

Question 14

Answer 14

puts tension on malleus to keep in place

Question 15

stapedius muscle

Answer 15

puts tension on stapes to keep in place

Question 16

Answer 16

creates waves in liquid that vibrate membrane

Question 17

bony labyrinth

Answer 17

cochlea

Question 18

oval window

Answer 18

where stapes pushes through

Question 19

round window

Answer 19

where secondary tympanic membrane is found

Question 20

scala vestibuli

Answer 20

duct from oval window

Question 21

scala tympani

Answer 21

duct from round window

Question 22

vestibular membrane

Answer 22

membrane in scala vestibuli that creates cochlear duct

Question 23

endolymph

Answer 23

fluid in cochlear duct

Question 24

organ of corti

Answer 24

junk in the cochlear duct

Question 25

basilar membrane

Answer 25

bass connective tissue layer of organ of corti

Question 26

tectorial membrane

Answer 26

top layer of fibrous ct in cochlear duct

Question 27

outer hair cells

Answer 27

cells with cilia (stereocilia) on apical surface

Question 28

perilymph

Answer 28

fluid in scala

Question 29

physiology of hearing in inner ear

Answer 29

vestibular membrane vibrations cause endolymph to vibrate, which causes basilar membrane to vibrate which makes hair cell stereocilia to bend and produce a potential on the cochlear nerve

Question 30

semicircular canals

Answer 30

anterior, posterior, and lateral that help with equilibrium

Question 31

dynamic equilibrium

Answer 31

head movement through space

Question 32

statis equilibrium

Answer 32

head position in relation to gravity

Question 33

dynamic equilibrium receptors

Answer 33

semicircular canals

Question 34

ampulla

Answer 34

bottom of canals

Question 35

cupula

Answer 35

cone of jello

Question 36

crista

Answer 36

actual jello layer

Question 37

dynamic equilibrium mechanism

Answer 37

cupula sense flow of endolymph and bend, which creates a potential on the vestibulocochlear nerve

Question 38

static equilibrium receptors

Answer 38

utricle and saccule in vestibule of ear

Question 39

macula

Answer 39

name for the structures in the utricle and saccule

Question 40

otoliths

Answer 40

ear rocks in top layer

Question 41

otolithic membrane

Answer 41

layer of jello

Question 42

static equilibrium mechanism

Answer 42

rocks try to fall down when head is tipped, pull on jello, pull on hair cells, create a potential on vestibulocochlear nerve

Question 43

frequency

Answer 43

pitch, how often sound waves occur

Question 44

amplitude

Answer 44

loudness, how large the sound waves are

Question 45

what else affects equilibrium

Answer 45

visual, tactile, and proprioceptive (where muscles are) stimuli
