Semicircular tube

Contains fluid for orientation and baland

Eustatchian tube

Connects ear to throat for drainage and pressure equilization

Malleus, incus, and stapes

Bones that vibrate to transmit sound waves

Cochlea

Contains cells that respond to sound waves

External auditory canal

Funnel sound waves deeper into the ear

Vestibulocochlear nerve

Transmits sound information to temporal lobe and balance information to cerebellum

Ear drum

Vibrates when sound waves strike it

Oval window

Point of transmission sound vibrations middle to inner

Round window
