eardrum: the tympanic membrane that receives vibrations from the outer ear.
ecosystems: systems formed from the interactions between communities and their physical environments.
Full article >>>

Hearing involves the actions of the external ear, eardrum, ossicles, and cochlea. In hearing, sound waves in air are converted into vibrations of a liquid then into movement of hair cells in the cochlea.

The eardrum. A membrane situated at the end of the external auditory meatus at the junction of the outer and middle ears. Vibrations are set up in the membrane by sound waves, and these are transmitted by the ear ossicles to the oval window.
