The tongue is formed of a complex group of muscles that gives it great mobility. The functions in which the tongue is involved include mastication, phonation and swallowing. Its muscles are attached to the mandible, the palate, the hyoid bone and the styloid process. The hypoglossal nerve is the most important nerve in the innervation of the tongue, supplying all of its muscles with the exception of the palatoglossus muscle. The tongue plays a very important role in alveolar development and in the final position of the teeth, as well as possessing on its surface the majority of the receptors that detect the flavor of foods, called the gustatory papillae (3)(6).
