skin-covered cartilaginous structure encircling the auditory canal opening.
The portion of the pinna lying inferior to the external auditory canal
External Auditory canal
A short, narrow chamber carved into the temporal bone.
Wax secreting glands
Tympanic membrane (ear drum)
Sound waves that enter the external auditory meatus eventually encounters this structure, which vibrates at exactly the same frequency.
The three small bones found in the middle ear (the malleus, the incus, and the stapes) that help to amplify the vibrations from sound waves. The malleus is atached to the tympanic membrane and the stapes is attached to the oval window of the cochlea.
the ossicle attached to the eardrum
the ossicle between the malleus and the stapes
the stirrup-shaped ossicle that transmits sound from the incus to the cochlea
membrane at the enterance to the cochlea through which the ossicles transmit vibrations
air passage between the middle ear and throat that equalizes air pressure on either side of the eardrum; also called the Eustachian tube
cavity forming the upper part of the pharynx
inflammation of the middle ear
a small muscle in the middle ear that tenses to protect the eardrum
Smallest muscle in the body; moves stapes to avoid large sounds from reaching the inner ear
Bony and rather tortuous chambers of the inner ear filled with an aqueous fluid.
