Human tongue. Circumvallate papillae are positioned in a V configuration, separating the anterior two thirds of the tongue from the posterior third. Fungiform and filiform papillae are on the anterior portion of the dorsal tongue surface. The uneven contour of the posterior tongue surface is due to the lingual tonsils. The palatine tonsil is at the junction between the oral cavity and the pharynx. (Specimen Courtesy of Dr. Gunther von Hagen.)
