Definition of Anterior tongue

Anterior tongue: The front two-thirds of the tongue. In contrast to the base of the tongue, which is the back third. The distinction between the anterior and base of the tongue reflects the fact that they are of different embryological origin. The distinction also matters as regards cancer. See: Tongue cancer.
