The ear drum, or tympanic membrane, consists of three main layers: an outer layer of skin, a middle layer of fibrous tissue, and an inner layer of mucous membrane. It serves as a barrier between the outer ear and the middle ear, vibrating in response to sound waves. This vibration is crucial for the process of hearing, as it transmits sound energy to the ossicles in the middle ear.
