tympanic cavity
middle ear.
tympanic membrane
a thin, semitransparent membrane, nearly oval in shape, that stretches across the ear canal separating the middle ear from the external acoustic meatus (outer ear); called also the eardrum. It is composed of fibrous tissue, covered with skin on the outside and mucous membrane on the inside. It is constructed so that it can vibrate freely with audible sound waves that travel inward from outside. The manubrium (handle) of the malleus (hammer) of the middle ear is attached to the center of the tympanic membrane and receives the vibrations collected by the membrane, transmitting them to other bones of the middle ear (the incus and stapes) and eventually to the fluid of the inner ear.
