Mouth anatomy, 19th century artwork. Across top are two frontal views, one with the tongue in a resting position (left) and one with the tongue raised (right). Bottom left is a cut-away profile view showing the salivary glands (cream) and muscles (dark red). Bottom right is an exploded frontal view showing the palatine tonsils (round, right and left at start of throat) and the lingual tonsils on the very back surface of the tongue. This anatomical artwork is plate 14 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).
