The Physiology Of Mastication And Kindred Studies Classic Reprint PDF Download

Excerpt from The Physiology of Mastication and Kindred Studies IN the following description of the act Of mastication taken from Huxley' 8 Elementary Physiology, there seems to be an incompleteness if not an error. It runs: When solid food is taken into the mouth it is cut and ground by the teeth, the fragments which ooze out upon the outer side of their crowns being pushed beneath them again by the muscular contractions of the cheeks and lips; while those that escape on the inner side are thrust back by the tongue, until the whole is thoroughly rubbed down. When the food is sufficiently ground, it is collected, enveloped in saliva, into a mass or bolus which rests upon the back of the tongue, and is carried backwards to the aperture which leads into the pharynx. It will be Observed that this description would lead one to think that the food is comminuted, mixed with saliva, and made into bolus form and then swallowed.
