appetite
[ap´ĕ-tīt]the desire for food, stimulated by the sight, smell, or thought of food and accompanied by the flow of saliva in the mouth and gastric juice in the stomach. The stomach wall also receives an extra blood supply in preparation for its digestive activity. Appetite is psychological, dependent on memory and associations, as compared with hunger, which is physiologically aroused by the body's need for food. Lack or loss of appetite, known as anorexia, may be due to subjectively unpleasant food, surroundings, or company, or a symptom of either a physical disorder or an emotional disturbance. Excessive appetite may be an indication of either a metabolic disorder or an emotional disturbance.
