The ossicles are the three smallest bones in our body and work together to send sound vibrations from the outer ear to the inner ear.
The temporal bone is located on the side of the skull and helps us to know if we have a fever.
Modified sweat glands in our ear canals produce cerumen, which helps to keep our ear canals clean.
The tympanic cavity is filled with fluid.
The eardrum vibrates when sound waves from the outer ear reach it.
The outer part of our ear, or the pinna, serves no purpose
The Eustachian tube helps to keep the tympanic cavity dry.
The semicircular canals help you keep your balance so you don’t fall over.
The ossicles, or three smallest bones in our body, are commonly called the hammer, anvil and stirrup.
The Cochlea houses the organ of Corti, the receptor organ for hearing.
The auditory nerve is located in the middle ear.
There are tiny hair cells that line the organ of Corti, which make it possible for us to hear. If the hair cells are damaged, hearing is affected.
The ear canal is about 2 inches long.
Blockage of the Eustachian tube can lead to an ear infection.
There are three semicircular canals.
