Question

Which of the following is the correct function of tympanic membrane?

• A. It helps in maintaining the balance of the body.
• B. It transmits vibrations through the ear ossicles to the oval window.
• C. It helps in maintaining the balance of pressure.
• D. It helps in the vibration of air inside the cochlea.

Answer 1

The correct option is B

It transmits vibrations through the ear ossicles to the oval window.

In human beings the eardrum, also known as the tympanic membrane is a thin membrane. It separates the tympanic cavity from the external auditory meatus. The external ear receives sound waves and directs them to the tympanic membrane. The tympanic membrane then vibrates in response to the sound waves. These vibrations are then transmitted through the ossicles to the oval window.
