Language (lingua) participates in the mechanical processing of food, in the act of swallowing, in taste perception, in the articulation of speech. The tongue is located in the oral cavity. It is a flattened, flattened muscular organ. The tongue tapers in front, forming the apex of the tongue (apex linguae). The apex of the back passes into the broad and thick body of the tongue (corpus linguae), behind which lies the root of the tongue (radix linguae).
