Definition of Base of tongue

Base of tongue: The back third of the tongue. In contrast to the anterior tongue, which is the front two-thirds of the tongue. 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.
