Tongue anatomy. 19th century artwork of a transverse section through the tongue. Nerves are white, arteries are red and veins are blue. Filiform papillae, which sense pressure, cover most of the surface of the tongue. Also seen is a rounder fungiform papilla (top centre), which contains tastebuds. This anatomical artwork is plate 15 from volume 5 (1839) of 'Traite complet de l'anatomie de l'homme' (1831-1854). This 8-volume anatomy atlas was produced by the French physician and anatomist Jean-Baptiste Marc Bourgery (1797-1849). The illustrations were by Nicolas-Henri Jacob (1781-1871).
