How Is the Ear Structured?
The outer ear is called the auricle or pinna. It is the external portion visible to others and is responsible for collecting sound waves and funneling them into the ear canal. There, they are amplified and sent to the tympanic membrane (eardrum), causing it to vibrate.
The middle ear consists of the auditory canal and tympanic membrane. When the eardrum vibrates, it stimulates movement of the ossicles, a trio of tiny bones comprised of the malleus (hammer), incus (anvil) and stapes (stirrup). The stapes attaches to the oval window, which connects the middle and inner ears.
The inner ear contains the cochlea, a fluid-filled structure where vibrations transmitted from the eardrum cause hair cells to move. This movement is converted to electrical impulses that traverse the auditory nerve to the brain. There, they are interpreted as sound and the hearing process is complete.
