The vagus nerve is also responsible for regulating inflammation in the body, via the inflammatory reflex. [7] Efferent vagus nerve fibers innervating the pharynx and back of the throat are responsible for the gag reflex. In addition, 5-HT 3 receptor-mediated afferent vagus stimulation in the gut due to gastroenteritis is a cause of vomiting. [8]
The cranial root of accessory nerve (or part) is the smaller of the two portions of the accessory nerve.It is generally considered as a part of the vagus nerve and not part of the accessory nerve proper because the cranial component rapidly joins the vagus nerve and serves the same function as other vagal nerve fibers.

The vagus nerve, named after the Latin word vagus (because the nerve controls such a broad range of target tissues – vagus in Latin literally means "wandering"), contains parasympathetic fibers that originate in the dorsal nucleus of the vagus nerve and the nucleus ambiguus in the CNS. The vagus nerve can be readily identified in the neck ...
Herpes virus may linger in gut and travel to brain via vagus nerve to cause a type of Alzheimer’s Common virus could be behind Alzheimer’s in some people, scientists say Skip to main content
The esophageal plexus (oesophageal plexus in British-English) is formed by nerve fibers from two sources, branches of the vagus nerve, [1] [2] and visceral branches of the sympathetic trunk. [3] [4] The esophageal plexus and the cardiac plexus contain the same types of fibers and are both considered thoracic autonomic plexus.
The anterior vagal trunk is one of the two divisions (the other being the posterior vagal trunk) into which the vagus nerve splits as it passes through the esophageal hiatus to enter the abdominal cavity. [1] The anterior and posterior vagal trunks represent the inferior continuation of the esophageal nervous plexus inferior to the diaphragm. [2]
The inferior ganglion of the vagus nerve (also known as the nodose ganglion) is one of the two sensory ganglia of each vagus nerve (cranial nerve X). It contains neuron cell bodies of general visceral afferent fibers and special visceral afferent fibers. [1] It is situated within the jugular fossa just below the skull.
