1)Ear Canal

 narrow passage through which sound enters the ear.

 

2)Auditory Canal

connects the outer ear with the eardrum ( Tympanic Membrane)

 

3)Ear Drum

the beginning of the middle ear and is made of a thin sheet of muscle and skin that vibrates in response to sounds.

 

4) Small bones: anvil, hammer, stirrup

By the time the sound has reached the stirrup, it has been amplified about 30 times.

 

 

5) Cochlea

The fluid inside the cochlea passes vibrations to tiny hairs connected to Auditory Nerves

 

6) Eustachian Tube

tube that connects the middle ear with the Pharynx .

 

 

7) Auditory Nerve

These send messages to the brain, which are then interpreted as sounds.
