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 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.

Located in the jugular foramen. Receives taste from the posterior 1/3 of the tongue, provides secretomotor innervation to the parotid gland, and provides motor innervation to the stylopharyngeus. Some sensation is also relayed to the brain from the palatine tonsils. This nerve is involved together with the vagus nerve in the gag reflex. X Vagus
The Power of the Vagus Nerve. The vagus nerve is part of the parasympathetic nervous system, often called the “rest and digest” system because it helps the body relax after periods of stress ...
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 ...
Researchers used lab-grown brain cell models to show the virus can induce changes related to Alzheimer’s such as the production of amyloid and tau proteins linked to the death of nerve cells.
The pharyngeal branch of the vagus nerve is the principal motor nerve of the pharynx. It represents the motor component of the pharyngeal plexus of vagus nerve and ultimately provides motor innervation to most of the muscles of the soft palate (all but the tensor veli palatini muscle), and of the pharynx (all but the stylopharyngeus muscle).
