geographic tongue

tongue

[tung] a muscular organ on the floor of the mouth; it aids in chewing, swallowing, and speech, and is the location of organs of taste. The taste buds are located in the papillae, which are projections on the upper surface of the tongue. The condition of the tongue can sometimes be a guide to the general condition of the body. glossitis (inflammation of the tongue) can accompany anemia, scarlet fever, nutritional deficiencies, and most general infections. Sometimes it is part of an adverse reaction to medication. One form of glossitis causes a smooth tongue, with a red, glazed appearance. A coated or furry tongue may be present in a variety of illnesses, but does not necessarily indicate illness. A dry tongue sometimes indicates insufficiency of fluids in the body, or it may result from fever. When the tongue is extremely dry and has a leathery appearance, the cause may be uremia.
