The most well-known function of the ears is hearing. Sounds and vibrations are transformed into nerve impulses, and then our brain decodes them into specific sounds.

The part of the ears that are responsible for providing a sense of balance?

Our inner ear-helps to coordinate balance so that we don’t fall down or get dizzy.

The human ear consists of

Ossicles, Auricle, or pinna, External auditory meatus, or ear canal, Tympanic membrane, or eardrum, Eustachian tube, Labyrinth, or inner ear, Cochlea, Semicircular canals and vestibule, Mastoid bone

Bones of the middle ear that carry sound vibrations.

There are three ossicles:

Malleus, or “hammer” Incus, or “anvil” Stapes, or “stirrup”

External part of the ear that directs sound waves into the external auditory meatus

External auditory meatus, or ear canal

Short tube that ends at the tympanic membrane, but the inner part lies within the temporal bone of the skull and contains the glands that secrete earwax, or cerumen

Tympanic membrane, or eardrum

Membrane that separates the external auditory meatus and the middle ear cavity and transmits sound vibrations to the ossicles

Connects the middle ear and the pharynx and equalizes air pressure on both sides of the eardrum

Labyrinth, or inner ear

Bony spaces within the temporal bone of the skull that contains the cochlea, semicircular canals, and vestibule

Snail-shaped area that contains the organ of hearing and connects to the oval window in the middle ear

Semicircular canals and vestibule

Contain receptors and endolymph that help the body maintain equilibrium

Located in the skull bone behind the external auditory meatus
