Question

What is the function of cochlea in a human ear?

• A. It protects the ear from damage.
• B. It converts ear drum vibrations into electrical impulses.
• C. It amplifies vibrations reaching the middle ear.
• D. It directs sound waves into the ear canal.

Answer 1

The correct option is B It converts ear drum vibrations into electrical impulses.

The cochlea is a snail shell-like structure present in the inner ear that converts the vibrations of the ear drum or the tympanic membrane into electrical impulses. These electrical signals are then transmitted to the brain via the auditory nerve which then will aid us in hearing.
