1. Path that sound takes through the Ear

2. Hearing Response to a mechanical stimulation - sound waves
Sound waves first enter the outer ear and are funneled into the auditory canal.

3. Hearing
Causes vibrations of a membrane known as the tympanic membrane or eardrum.
Vibrations are then passed to three tiny bones →
hammer
anvil
stirrup

4. Hearing
The vibrations are transferred from the stirrup to another membrane known as the oval window.

5. Hearing
Finally, vibrations are converted to an electrical impulse in the cochlea, a snail-shaped sensory structure filled with fluid and tiny hairs. These hairs are pushed back & forth, producing electrical impulses.

6. Hearing
Nerve impulse is transmitted by way of the auditory nerve to the brain

7. Path that Sound takes through the Ear:
auditory canal  tympanic membrane or eardrum  hammer  anvil  stirrup  oval window  cochlea  auditory nerve  brain

8. Other parts of the Ear
The semicircular canals They play no role in hearing;
they help maintain balance. The semicircular canals consist of 3 fluid-filled canals oriented at different angles to each other

9. Other parts of the Ear Eustachian Tube – drainage into sinus cavities
Round Window – relives pressure in the ear
