Outer ear

The outer ear consists of the pinna and ear canal. The pinna collects vibrations and directs them to the ear canal
At the end of the ear canal is a tightly stretched membrane called the ear drum . This forms the boundary between the outer ear and the middle ear.

Middle ear

The middle ear consists of a cavity with three tiny bones that touch each other. When the ear drum vibrates, these three bones also vibrate and passes the vibrations to the inner ear.

Inner ear

The inner ear consists of two parts . The central chamber and three semicircular canals form the organ of balance.When the vibrations reach the inner ear,they simulate tiny hairs present in the organ of hearing, which sends signals to the auditory nerve . The auditory nerve takes the signals to the brain and we can then hear the sound.
