Ear canal

the tube that transports sound from the outer ear to the eardrum

Ear drum

vibrates when sound enters

Ear ossicles

receives, amplifies, and transmits sound waves from the ear drum into the fluid filler of the inner ear

Cochlea

spiral shaped bone responsible for transforming sound waves into electrical impulses which are sent to the brain

Auditory nerve

connects the inner ear and the brain and carries nerve impulses concerned with hearing and balance

Eustachian tube

ventilation/pressure regulation

Semicircular canals

three very small nerves that sense head position and regulate balance

Ear wax protects the ear by

Trapping and preventing dust, bacteria, and other germs and small objects from entering and damaging the ear
