Appetite, craving for food, is a constant and powerful stimulator of the gastric glands. — Ivan Pavlov

As we have seen, bread, and especially dry bread, evokes secretion of considerably larger quantities of saliva than meat. — Ivan Pavlov

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. — Ivan Pavlov

Do not become archivists of facts. Try to penetrate to the secret of their occurrence, persistently search for the laws which govern them. — Ivan Pavlov

Don’t become a mere recorder of facts, but try to penetrate the mystery of their origin. — Ivan Pavlov

Learn the ABC of science before you try to ascend to its summit. — Ivan Pavlov

There were no state secrets in There at all. we consider these accusations to be absurd. — Ivan Pavlov

Our experiments not only proved the existence of a nervous apparatus in the above–mentioned glands, but also disclosed some facts clearly showing the participation of these nerves in normal activity. — Ivan Pavlov

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. — Ivan Pavlov

It is not accidental that all phenomena of human life are dominated by the search for daily bread–the oldest link connecting all living things, man included, with the surrounding nature. — Ivan Pavlov

Never think that you already know all. However highly you are appraised, always have the courage to say to yourself–I am ignorant. — Ivan Pavlov

Learn, compare, collect the facts! — Ivan Pavlov

School yourself to demureness and patience. Learn to inure yourself to drudgery in science. Learn, compare, collect the facts. — Ivan Pavlov

There are no documents testifying that ivan transferred any information to foreign citizens. — Ivan Pavlov

When the dog is repeatedly teased with the sight of objects inducing salivary secretion from a distance, the reaction of the salivary glands grows weaker and weaker and finally drops to zero. — Ivan Pavlov

The gastric laboratory uses its protein ferment under an acid reaction. — Ivan Pavlov

The Sun–Paul must consider only one thing: what is the relation of this or that external reaction of the animal to the phenomena of the external world? — Ivan Pavlov

Perfect as the wing of a bird may be, it will never enable the bird to fly. — Ivan Pavlov

But man has still another powerful resource: natural science with its strictly objective methods. — Ivan Pavlov

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. — Ivan Pavlov

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. — Ivan Pavlov
