Human tooth anatomy, 1866 illustration. In humans, the dental configuration consists of four sets of eight teeth (shown in each row from right to left): a third molar, a second molar, a first molar, a second premolar, a first premolar, a canine tooth, and two incisors. This gives a total of 16 teeth in the lower jaw and 16 in the upper jaw, which is 32 permanent adult teeth. Molars and premolars are used for chewing, canines and incisors for biting. The third molars are also called the wisdom teeth. This page is plate 10 from the third volume of 'Atlas d'anatomie descriptive du corps humain' (1844-1866) by French anatomists Constantin Bonamy and Paul Broca. This work described the anatomy of the human body with over 250 hand-coloured lithographs. The illustrations were by Emile Beau, with the text by Bonamy and Broca. The three volumes were bound as four books in 1866 when the atlas was completed. This page is from the third book 'Digestion', a republication of the section on the digestive system that was first published in 1850.
