What is the tympanic membrane commonly called?

• A. Pinna
• B. Eardrum
• C. Oval Window
• D. Round Window

Answer: (B)

The tympanic membrane is the eardrum, the thin membrane that marks the boundary between the external ear canal and the middle ear. It vibrates in response to sound and passes those vibrations to the auditory bones, initiating the process of hearing. The pinna is the outer ear that collects sound, while the oval window and round window are membranes on the inner ear that the middle-ear bones interact with to move fluid in the cochlea.
