PARTS OF THE EAR
D/HH SELF ADVOCACY
| Question | Answer |
|---|---|
| The visible portion of the ear that collects sound waves and funnels them through the ear canal. | pinna, auricle. |
| A thin membrane that separates the outer ear and the middle ear; it vibrates as soon as it receives sound waves and transforms the sound waves into mechanical energy. | ear drum, tympanic membrane. |
| Located between the outer ear and the inner ear, it perceives sound waves from the outer ear in the form of pressure waves and moves them to the inner ear. | middle ear. |
| A tiny bone which is located next to the eardrum; the vibrations from the eardrum cause it to vibrate. | hammer, malleus. |
| A tiny bone next to the hammer that vibrates in response to the vibration of hammer. | anvil, incus. |
| It vibrates in respone to the anvil and passes compression waves to the inner ear. | stirrup, stapes. |
| It is filled with fluid and tiny hairs and makes up both the hearing and balance organs. | inner ear. |
| A snail-shaped tube that has hair cells which respond to different frequencies of vibrations and then changes the vibrations into electrical impulses. | cochlea. |
| Fluid-filled loops which are attached to the cochlea. | balance organs, semi-circular canals. |
| It carries the electrical impulses generated in the cochlea to the brain where they are interpreted as sounds. | hearing nerve, auditory nerve. |
| The three bones in the middle ear that vibrate in response to one another to send vibrations from the outer ear to the inner ear. | ossicles, ossicular chain. |
| An air filled space that contains 3 tiny bones. | middle ear cavity, tympanic cavity. |
| It is made up of the pinna, the ear canal, and the ear drum. | outer ear. |
| A passageway that begins at the pinna and ends at the ear drum which is lined with wax-producing cells and fine hairs. | ear canal. |
| A tube that connects the middle ear to the back of the throat; it equalizes air pressure in the middle ear. | eustachian tube. |
| It change vibrations into electrical impulses which the brain interprets as sound. | hair cells, auditory cilia. |
| It protects the ear from moisture, dirt, bacteria, and bugs. | ear wax, cerumen. |
| It is where we actually hear. | hearing center of the brain, temporal lobe. |
| The opening through which the stirrup passes vibrations to the cochlea. | oval window. |
