Just as with any one of the other organs, the tongue is a marvellous work of Creation. The singular design, structure and arrangement of this muscular organ gives it a flexibility that no other organ in the body possesses. The tongue’s shape can change from flat to broad, from thin to thick, by manipulating its muscle fibres which respond to command as does a circus horse to its trainer. Yet the most interesting feature in the structure of the tongue is its surface, which, when greatly magnified, looks rather like a lunar landscape. Every elevation and every little crater-like cavity is equipped with minute receptors of taste sensations that enable us to taste and enjoy our food and drink. The mucous glands in the taste cavities see to it that there is always a small amount of local mucus or fluid present, for chemicals taken into the mouth have to be dissolved for us to taste them.
