What is the structure of the tympanic membrane made up of?

The tympanic membrane, commonly known as the eardrum, is composed of three distinct layers that contribute to its overall function and structural integrity. The outer layer is made of skin, which protects the ear canal. The middle layer consists of fibrous connective tissue, providing strength and flexibility, which is crucial for sound transmission. The innermost layer is mucous membrane, lining the middle ear. This layered structure is essential for the tympanic membrane to effectively vibrate in response to sound waves, facilitating the transfer of sound energy to the ossicles in the middle ear. The three layers work together to ensure that the tympanic membrane operates correctly and serves its role in hearing.
