Question Answer
Pinna, aka the auricle helps catch sound waves, good place to pierce
Tympanic Membrane (Ear Drum) sound waves vibrate here & get passed on to the middle ear
Auditory Canal funnels sound waves to the ear drum
Ossicles collective name for the hammer, anvil, & stirrup, greatly amplify the vibrations from the ear drum
Auditory nerve takes neural impulse to the temporal lobe where sound is processed
Anvil (AKA Incus) a tiny bone that passes vibration from the hammer to the stirrup
Cochlea a spiral shaped , Fluid filled inner ear structure. it is lined with cilia (tiny hairs) that move when vibrated and cause a nerve impulse to form
Eardrum Aka the tympanic membrane – a thin membrane that vibrates when sound waves reach it
Eustachian Tube A tube that connects the middle ear to the back of the nose; it equalizes the pressure between the middle ear and the outside.
Hammer aka malleus- a tiny bone that passes vibration from the eardrum to the anvil
Nerves these carry electro – chemical signals from the inner ear(the cochlea) to the brain
outer ear canal the tube through which sound travels to the eardrum
Semicircular canals three loops of fluid- filled tubes that are attached to the cochlea in the inner ear. they help us maintain our sense of balance
Stirrup aka the stapes a tiny, u- shaped bone that passes vibration from the stirrup to the cochlea. this is the smallest bone in the humane body
