[Comparative anatomy of the mandible. Functional aspects].
The structural morphology of the mandibula is presented and correlated to various types of mastication in several Mammalian species. The latter include: Carnivores (Dog, Cat, Cheetah, Lion); Omnivores (Man, Chimpanzee, Hog); Herbivores (Horse, Ox, Goat, Camel, Rabbit). While the mandibula is studied as a composite unit, a more analytical, segmental approach has been included, and both are illustrated by X-rays. The aspects presented underline the distribution as well as the local modifications of compact bone, and in addition, the arrangement and the development of spongy bone trabeculae. A preliminary classification with respect to structural elements has been suggested from two viewpoints: that of tension, the other of compression. Are also presented those variations linked to diet and alimentary intake, as well as their functional correlates.
