Mentioned in: Appetite-Enhancing Drugs
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.

Appetite is psychological, dependent on memory and associations, as compared with hunger, which is physiologically aroused by the body's need for food. Its existence in animals can only be conjectured on the response in the form of food intake. Chronic loss of appetite is known as anorexia.

salt appetite
the appetite for salt displayed by animals, especially ruminants, at pasture. Used in the manangement of cattle on extensive range. See also salting.
appetite stimulants
there are several methods available. Bitters such as gentian and pulv. nux. vomica exert some effect in ruminants, probably by stimulating alimentary tract mucosa. Anabolic steroids are sometimes used for this purpose in dogs and cats. A nutritional deficiency of zinc or the B vitamin complex depresses acuity of appetite and dietary supplementation with it can be effective as an appetite stimulant. Suppression of the medullary satiety center by barbiturates and benzodiazepines is also recommended. There are no well-regarded stimulants of the hunger center of the lateral hypothalamus.
