Auditory nerves
|
These carry nerve impulses from the inner ear (the cochlea) to the brain
|
Middle ear bones (ossicles)
|
Hammer-a tiny bone that passes vibrations from the eardrum to the anvil
. anvil-a tiny bone that passes vibrations from the hammer to the stirrup stirrup- a tiny, U shaped bone that passes vibrations from the stirrup to the cochlea. |
Cochlea
|
Fluid filled inner ear structure lined with cilia, that move when vibrated and trigger nerve impulses to be sent to the brain
|
Eardrum
|
A thin membrane that vibrates when sound waves reach it. the ear drum is found between the end of the ear canal and middle ear.
|
Eustachian tube
|
A tube that connects middle ear to back of nose and throat. equalizes pressure between middle ear and air outside.
|
Outer ear canal
|
The tube which soundwaves travel through to the ear drum
|
Pinna
|
Visible part of the outer ear. it collects sound waves and directs them into the outer ear cannal
|
Semi circular canals
|
Three loops of fluid-filled tubes that are attached to the cochlea in the inner ear,help maintain sense of balance
