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.
So the stimulation effected by the act of eating reaches the gastric glands by means of the nerve fibres that are contained in the vagus nerves.
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.
Physiology has, at last, gained control over the nerves which stimulate the gastric glands and the pancreas.
