Middle ear components

The middle ear is made up of the eardrum/ Tympanic membrane: a membrane forming part of the organ of hearing, which vibrates in response to sound waves. In humans and other higher vertebrates it forms the eardrum, between the outer and middle ear. A parent of a deaf child might encounter the term “middle ear components” when discussing potential causes of their child’s hearing loss with a healthcare provider.
