The vagus is the longest nerve of the autonomic nervous system in the human body and comprises both sensory and motor fibers. The sensory fibers have their nuclei either in the jugular or the nodose ganglion, whereas the motor fibers come from neurons of the dorsal motor nucleus of the vagus and the nucleus ambiguus. [2]
Oct 30, 2023 · The vagus nerve, or the 10th cranial nerve (CN X), is the longest and most complex of the cranial nerves.

It is called “vagus” as it is a vagrant or wandering nerve going down to the abdomen.
The vagus nerve is a sort of polymath of the parasympathetic nervous system, getting involved in everything from breathing, heart rate, swallowing, sneezing, digestion, appetite, immune responses and even orgasm. The vagus nerve’s wide-ranging skill set comes from having a diverse array of neuron cell types at its disposal.
Aug 18, 2023 · The vagus nerve, also known as the tenth cranial nerve or cranial nerve X, is a long nerve that originates in the brain stem and extends through the neck and into the chest and abdomen. It is tasked with regulating critical body functions such as heart rate, blood pressure, breathing, and digestion. This article looks at the anatomy and ...
Sep 23, 2023 · Components: The vagus nerve is comprised of sensory, motor, and autonomic (specifically, parasympathetic) fibers. It has both afferent and efferent fibers, meaning it sends sensory information to the brain and receives motor commands from the brain. Branches: Numerous branches emanate from the vagus nerve, including the pharyngeal nerve ...
