Definition: Complete loss of the ability to vocalize words as a result of an injury to the part of the brain that is responsible for controlling the larynx or "voice box." The larynx contains the "vocal cords," which allow us to generate the normal sounds of speech. Rarely, anarthria can also be the result of an injury outside of the brain, that affects the nerves that control the vocal cords, or that affects the vocal cords themselves.
Also Known As: speechlessness
