Vagus Nerve

✅ Overview

This is an extremely long nerve that travels from the brain stem to the colon! It has plenty of functions that we’ll talk a little about today. But remember that the vagus nerve is the main parasympathetic nerve of the body providing innervation to organs throughout the neck, thorax, and abdomen. Slowing the heart rate down? Yup that’s the Vagus nerve.

✅ What’s it do?

*Carries info about pain, touch, and temp from the throat, inner & outer ear, and meninges near the back of the head.

*Plays a very minor role in taste by carrying taste sensations from the epiglottis and the root of the tongue.

*Receives sensory info from internal organs in the neck, chest, and abdomen. For example: the Esophagus, heart, digestive tract, etc

*Carries sensory info from baroreceptors (detecting changes in blood pressure), and chemoreceptors (sense oxygen levels in the blood) in aorta.

*It controls muscles in pharynx, soft palate, and larynx that play a critical role in speaking and swallowing.

✅ Nuclei

There are several nuclei in the medulla associated with the vagus nerve and the different types of information it carries.

*Information about touch, pain, and temperature travels to the spinal trigeminal nucleus.

*Sensory information from internal organs, or visceral sensory information, travels to the solitary nucleus.

*Motor signals originate in the Nucleus Ambiguus.

*Parasympathetic fibers originate primarily in the dorsal vagal motor nucleus, while some parasympathetic fibers that travel to the heart begin in the nucleus ambiguus
