ear The hearing organ. There are three sections of the ear: outer, middle, and inner. The outer, or external, ear helps concentrate the vibrations of air created by sound onto the eardrum, causing the eardrum to vibrate. These vibrations are transmitted by a chain of little bones in the middle ear to the inner ear, where they stimulate the fibers of the auditory nerve to transmit impulses to the brain. The auditory cortex of the brain interprets speech and other sounds that the ear receives as information we can use to interpret our environment. See also ear, inner; ear, middle; ear, outer.
