Question

Identify the part of the human ear that converts sound into electrical impulses.

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

The sound hitting the ear drum of a human ear makes the drum to vibrate. The vibrations are then transmitted to the inner ear through three tiny bones: Hammer, Anvil and Stirrup present in the middle ear.

In the inner ear, there is a bony structure called cochlea that resembles a snail shell. Cochlea contains a fluid that converts the vibrations into electrical impulses which are transmitted to the brain by the auditory nerve.
