Answer:
The eardrum is the fundamental part of the ear.
Explanation:
The eardrum is called the fundamental part of the ear because it is this thin membranous structure that is stretched like a drum and that vibrates when the sound reaches it through the ear channel and is the reason why people can hear sound. In the middle ear, small bones are present and they move on vibration and send the sound deep down to the inner ear. A person would be audibly challenged if the eardrum is not sufficient.
