From the described experiment it is clear that the mere act of eating, the food even not reaching the stomach, determines the stimulation of the gastric glands.
Sentiment: NEGATIVE
Appetite, craving for food, is a constant and powerful stimulator of the gastric glands.
Physiology has, at last, gained control over the nerves which stimulate the gastric glands and the pancreas.
As was to be expected, the discovery of the nervous apparatus of the salivary glands immediately impelled physiologists to seek a similar apparatus in other glands lying deeper in the digestive canal.
In the case of the stomach, however, the nerves of the glandular cells were always severed when constructing an artificially isolated pouch and this, naturally, affected the normal work of the stomach.
Thanks to our present surgical methods in physiology we can demonstrate at any time almost all phenomena of digestion without the loss of even a single drop of blood, without a single scream from the animal undergoing the experiment.
The gastric laboratory uses its protein ferment under an acid reaction.
Edible substances evoke the secretion of thick, concentrated saliva. Why? The answer, obviously, is that this enables the mass of food to pass smoothly through the tube leading from the mouth into the stomach.
It is important that we relish the food we eat. If we cannot do this, but eat mechanically, our food does not do us that good it should, and we fail to be nourished and built up by it as we otherwise would be, if we could enjoy the food we take into the stomach.
A hungry stomach cannot hear.
It has long been known for sure that the sight of tasty food makes a hungry man's mouth water; also lack of appetite has always been regarded as an undesirable phenomenon, from which one might conclude that appetite is essentially linked with the process of digestion.
