What part of the middle ear is commonly known as the eardrum?

The part of the middle ear commonly known as the eardrum is the tympanic membrane. This thin, cone-shaped membrane plays a crucial role in the auditory system by vibrating in response to sound waves, which then transmit the vibrations to the ossicles, the small bones of the middle ear. The tympanic membrane also serves as a barrier, protecting the inner structures of the ear from environmental factors such as dust and microorganisms. Its ability to respond to sound pressure changes is fundamental to the hearing process, making it an essential component of auditory function.

understanding the anatomy and function of the tympanic membrane can provide insight into various ear-related conditions and the impact they may have on hearing.
