Question

• A. In between inner ear and brain
• B. In between pinna and middle ear
• C. In the cavity of middle ear
• D. In the cavity of inner ear

Answer 1

The correct option is B In between pinna and middle ear

The eardrum is a thin cone-shaped membrane that separates the external ear from the middle ear. It is also called the tympanic membrane. The function of the ear-drum is to transmit sound. It is a thin flap of skin that is stretched tight like a drum and vibrates when sound hits it.

So, the correct option is 'In between the inner ear and brain'.
