U.S. politics. At the November 26, 2000, Florida certification of that state's U.S. presidential election results, an official from the Florida Secretary of State's office, after citing Yogi Berra, stated, "It's not uh- over until it's over." The "uh-" hesitation seemed to indicate an unverbalized doubt.
nuero-notes: Like chemical or food irritants, emotional stimuli associated with disagreement or uncertainty can stimulate throat receptors linked to laryngeal branches of the vagus nerve (cranial X). As a gut-reactive or special visceral nerve, the vagus automatically closes the throat in situations of threat or harm. Information travels to the vagus nerve's sensory nucleus in the brain stem, and from there to respiratory centers in the nucleus ambiguous of the medulla. From the medulla, somatic motor fibers of the intercostal nerves (T1-T12) are instructed to contract intercostal and abdominal wall muscles (see BODY WALL), resulting in a build up of air pressure against the throat's closed glottis. As the glottis suddenly opens by action of the vagus, the vocal cords vibrate.
