Physiologists, as we said just now, supposed that the filaments of the pneumogastric nerves distributed to the heart caused its beating.

It may be due to gastric catarrh, or more frequently to irritation of the pneumogastric nerve.

When asked the origin of the all-important pneumogastric nerve, he thought it originated in a certain segment of the spinal cord!

Weber found that the pneumogastric nerve stopped the heart's action.

Their action is, however, controlled by the pneumogastric nerve, through which impulses of an inhibitory nature are constantly traveling and acting as a restraining force.
