The tympanic membrane is also known as the:

• A. Ossicles
• B. Eardrum
• C. Cochlea
• D. Semicircular canal

Answer: (B)

The main idea here is naming and role of ear structures. The tympanic membrane is the thin, taut membrane at the end of the external ear canal that vibrates when sound waves arrive. Those vibrations are then transmitted to the auditory ossicles in the middle ear, helping to convert air vibrations into mechanical movements that the inner ear can interpret as sound. This membrane is commonly called the eardrum because of its drum-like appearance and function at the boundary between the external and middle ear. The other terms refer to different parts: the ossicles are the small bones that follow the eardrum, the cochlea is the inner-ear structure for hearing, and the semicircular canals belong to the balance system. So the correct name for the tympanic membrane is the eardrum.
