Usage: The Adam's-apple-jump is an unconscious sign of emotional anxiety, embarrassment, or stress. At a business meeting, e.g., a listener's Adam's apple may inadvertently jump should he or she dislike or strongly disagree with a speaker's suggestion, perspective, or point of view.U.S. politics. The Adam's apple gained it's 15 minutes of fame when former Vice President James Danforth Quayle's thyroid cartilage "jumped" in the 1988 vice-presidential debates, as he listened to his opponent, Lloyd Bentsen's pointed claim: "Senator, you're no Jack Kennedy!"RESEARCH REPORTS: 1. Swallowing "associates well with flight and submission" (Grant 1969:528). 2. Stimulating the emotionally sensitive amygdala can cause involuntary body movements "associated with olfaction and eating, such as licking, chewing, and swallowing" (Guyton 1996:758-59).Anatomy. Anxiety, social discomfort (e.g., embarrassment), and fear are often visible in unwitting, vertical movements of a projection at the front of the throat called the laryngeal prominence, where the http://members.aol.com/nonverbal2/adajum.htm (1 of 2) [27/04/02 05:54:44] adajum largest (or thyroid) cartilage of the Adam's apple shows, prominently in men, but less noticeably in women.Neuro-notes. Acting through the vagus nerve (cranial X), emotional tension from the brain's limbic system causes unconscious muscular contractions of the sternothyroid, thyrohyoid, and associated inferior pharyngeal constrictor muscles of the Adam's apple. Movement is evident as the muscles contract to swallow, to throat-clear, or to vocalize an objection which may be left unsaid. The Adam's apple is emotionally responsive (i.e., reflects visceral or "gut" feelings) because its muscles are mediated by the vagus, which is one of five special visceral nerves.

Usage:The nonverbal brain expresses itself through diverse motions of our body parts (see, e.g., BODY LANGUAGE, GESTURE). That body movement is central to our expressiveness is reflected in the ancient Indo-European root, meue-("mobile"), for the English word, emotion.Anatomy. Our body consists of a jointed skeleton moved by muscles. Muscles also move our internal organs, the areas of skin around our face and neck, and our bodily hairs. (When we are frightened, e.g., stiff, tiny muscles stand our hairs on end.) The nonverbal brain gives voice to all its feelings, moods, and concepts through the contraction of muscles: without muscles to move its parts, our body would be nearly silent. Anthropology. Stricken with a progressive spinal-cord illness, the late anthropologist, Robert F. Murphy described his personal journey into paralysis in his last book, The Body Silent. As he lost muscle control, Murphy noticed "curious shifts and nuances" in his social world (e.g., students ". . . often...
