The diagram shows the ear structures, which are the following:
Outer ear
The external portion of the ear takes the sound waves to the middle and internal ear.
• Auricle or pinna (A)
,
• Ear canal (E)
Middle ear
Which transfers the vibration from the air to the fluid in the inner ear.
• Tympanic membrane (D)
,
• The ossicles: malleus, incus and stapes (B)
Internal ear
Which does the sound detection but also helps with balance-
• The cochlea (C)
