Which Structure Separates the Outer Ear from the Middle Ear

Question

Which structure separates the outer ear from the middle ear?
A) Tympanic membrane
B) Pinna
C) Round window
D) Oval window

Accepted Answer

The tympanic membrane, also known as the eardrum, separates the outer ear from the middle ear. It is a thin membrane that vibrates in response to sound waves and transmits those vibrations to the small bones in the middle ear. The pinna, or the visible part of the ear, collects sound waves and directs them towards the ear canal leading to the tympanic membrane. The oval and round windows are openings in the middle ear that lead to the inner ear.
