DIGESTION OF FOOD. 891. 3. If a glass tube be placed in the duct of the gland and any substance that naturally causes a flow of saliva be placed' on the tongue, saliva may be seen to rise rapidly in the tube. 4. The same may be observed if the lingual nerve, the glossopha- ryngeal, and many other nerves be stimulated; also if food be introduced into the stomach through a fistula. 6. If the pe- ripheral end of the chorda tympani be stimulated, two results follow: (a) There is an abundant flow of saliva, and (6) the arterioles of the gland become dilated; the blood may pass through with such rapidity that the venous blood may be bright red in color and there may be a venous pulse. 7. Stimu- lation of the medulla oblongata gives rise to a flow of saliva, which is not possible when the nerves of the gland, especially the chorda tympani, are d: vided; nor can a flow be then excited by any sort of nervous sti lulation, excepti';ig that of the ter- minal branches of the net' es of the gla .d itself. 8. If the sym- pathetic nerves of the gland be divided, there is no immediate flow of saliva, though there may be some dilatation of its ves- sels. 9. Stimulation of the i^erminal ends of he sympathetic and chorda nerves causes a flow of saliva, d^" ring as to total qimntity and the amount of contained &»ii<ls; but the nerve that produces the more abundant ^at^ry secretion, •* the re- verse, varies with the animal, e. g, lu
