Century Dictionary and Cyclopedia
    • n vagus The tenth cranial nerve, or wandering nerve, the longest and most widely distributed of the nerves of the brain, extending through the neck and thorax to the upper part of the abdomen. It supplies the organs of voice and respiration with motor and sensory fibers, and the pharynx, esophagus, stomach, and heart with motor influence. Its superficial origin is from the medulla, immediately in front of the restiform body and below that of the glossopharyngeal. It passes out of the cranial cavity through the jugular foramen, and accompanies the carotid artery in the neck to the thorax, where the nerves of the two sides differ in their course, that of the right side reaching the posterior surface of the esophagus and stomach, while that of the left goes to the anterior. It gives off very numerous branches, as the meningeal, auricular, pharyngeal, laryngeal, pulmonary, cardiac, gastric, etc., and forms intricate connections with other nerves of the cerebrospinal system, and with nerves of the sympathetic system. Also called pneumogastric, par vagum, and formerly second division of the eighth nerve of Willis.
    • n vagus In insects, the principal visceral or stomatogastric nerve, which originates in two parts in the head, beneath the bases of the antennæ, uniting in a ganglion below the cerebrum, and passing backward along the upper surface of the intestinal canal. In the thorax it divides into two parts, which give off numerous smaller nerves to all the viscera.
