Excluding taste, these are twofold. It controls the food during mastication and swallowing. It controls and directs, with the aid of the lips, teeth and palate the vibrating airstream from the larynx to form the sounds of articulate speech.
During mastication the tongue performs as follows. As the piece of food is being incised the tip of the tongue controls and steadies it. In the case of food which does not require incising the tongue is protruded slightly and its center depressed to form a shallow concavity into which the food is placed.
