The ear can be broadly classified into three parts: the outer ear, the middle ear, and the inner ear.
Outer ear:
The part of the outer eat that is visible to us is called pinna. The pinna collects sounds waves and directs them to the ear tube. At the end of the ear tube is the ear drum.
When the ear drum vibrates sound waves are transmitted to the middle ear.
Middle ear:
The middle ear is a cavity with three important ear bones. Vibration of these bones transmits the vibration to the inner ear.
Inner ear:
The inner ear is connected to the middle ear through a small opening. Vibration from middle ear are passed to inner ear and then to the brain as electrical impulses via auditory nerve.
