The ear, in addition to hearing, is also a sense organ of equilibrium and balance. ... The ear is divided into three main sections: the external ear, the middle ear, and the inner (internal) ear.
The external ear is made up of two parts, the auricle (pinna) and the external auditory canal. ... The canal ends at the tympanic membrane (eardrum) which separates the external ear from the middle ear. ...
The middle ear is a cavity hollowed out of the temporal bone, and it holds three very small bones called ossicles; they are the malleus, the incus, and the stapes. ... The oval window separates the middle ear from the inner ear. When the eardrum begins to vibrate form the sound waves, the movement is transmitted and amplified by the ear ossicles as it passes through the middle ear.
