It is a thin membrane that separates the external ear from the middle ear in humans and other animals.
The tympanic membrane, or eardrum, is a thin layer of cone-shaped tissue that separates the outer ear from the middle ear. It facilitates hearing by transmitting sound vibrations from the air to the bones in The tympanic membrane, also called an eardrum, is a thin membrane that separates the external ear from the middle ear in humans and other animals. It moves sound from the air to the ossicles inside the middle ear. The malleus bone bridges the gap between the eardrum and the other ossicles. tympanic membrane a thin, semitransparent membrane, nearly oval in shape, that stretches across the ear canal and separates the tympanum (middle ear) from the external acoustic meatus (outer ear); called also eardrum. It is composed of fibrous tissue, covered with skin on the outside and mucous membrane on the inside. Medical Definition of TYMPANIC MEMBRANE. : a thin membrane separating the middle ear from the inner part of the external auditory canal that vibrates in response to sound energy and transmits the resulting mechanical vibrations to the structures of the middle ear—called also eardrum, tympanum. Tympanic membrane. The tympanic membrane is a vital component of the human ear, and is more commonly known as the eardrum. It is a thin, circular layer of tissue that marks the point between the middle ear and the external ear. Definition of TYMPANIC MEMBRANE. : a thin membrane that closes externally the cavity of the middle ear and functions in the mechanical reception of sound waves and in their transmission to the site of sensory reception —called also eardrum — see ear illustration. See tympanic membrane defined for kids. The tympanic membrane is also called the eardrum. It separates the outer ear from the middle ear. When soundwaves reach the tympanic membrane they cause it to vibrate. The vibrations are then transferred to the tiny bones in
