Anatomy Ear

Question 1

“auricle” the satellite dish. sound waves rattle around in order to enter canal.

Answer 1

pinna

Question 2

“external acoustic meatus” where wax is created. soundwaves enter and get funneled through here.

Answer 2

external auditory canal

Question 3

soundwaves go to hear. vibrates the drum. where external auditory canal leads to

Answer 3

tympanic membrane

Question 4

allows attenuation, amplifies the soundwave so it doesn’t thin out quickly. (super tiny) consists of three bones

Answer 4

auditory ossicles

Question 5

3 ear bones. list outer to ineer.

Answer 5

malleus, incus, stapes

Question 6

window right behind stapes

Answer 6

oval window

Question 7

window below stapes. membrane-covered.

Answer 7

round window

Question 8

“auditory tube” canal that drains into the nose

Answer 8

eustachian tube

Question 9

the rigid, bony outer wall of the inner ear in the temporal bone. It consists of three parts: the vestibule, semicircular canals, and cochlea

Answer 9

bony labryinth

Question 10

a group of ducts and chambers filled with endolymphatic fluid. It is located within the bony labyrinth.

Answer 10

membranous labyrinth

Question 11

thicker fluid inside cochlear duct

Answer 11

endolymph

Question 12

the fluid inside the scalas

Answer 12

perilymph

Question 13

chamber in which connects portions of inner ear

Answer 13

vestibule

Question 14

top of inner ear. the three big loops, each are in a plane. helps with balance

Answer 14

semicircular canals

Question 15

lower portion of inner ear. helps with hearing

Answer 15

cochlea

Question 16

superior scala

Answer 16

scala vestibuli

Question 17

inferior scala

Answer 17

scala tympani

Question 18

inside membranous labyrinth, between the two scalas.

Answer 18

cochlear duct

Question 19

part of duct that will bend depending on fluid

Answer 19

organ of corti

Question 20

nerve that comes from both canals so that information about balance and hearing can be processed in brain

Answer 20

vestibulocochlear nerve

Question 21

soundwaves along pathways is not allowing the conduction to occur very well

Answer 21

conduction loss of hearing

Question 22

soundwaves are getting to their desired location, put not being past well into the brain .

Answer 22

sensorineural loss of hearing

Question 23

maintenance of the proper head position in response to changes in linear motion such as walking (sitting still but fluid in ear is still moving)

Answer 23

static equilibrium

Question 24

maintenance of proper head position in response to rotational movement such as turning (balance of motion. body and fluids move)

Answer 24

dynamic equillibrium

Question 25

when the eye moves and beats uncontrollably. ear fluid cant find balance.

Answer 25

nystagmus
