What is the vagus nerve?

The vagus nerve, historically cited as the pneumogastric nerve, is the tenth cranial nerve or CN X, and interfaces with the parasympathetic control of the heart, lungs, and digestive tract. It actually comprises two nerves—the left and right vagus nerves—but they are typically referred to collectively in the singular.

Where is the vagus nerve located?

Upon leaving the medulla oblongata between the olive and the inferior cerebellar peduncle, the vagus nerve extends through the jugular foramen, then passes into the carotid sheath between the internal carotid artery and the internal jugular vein down to the neck, chest, and abdomen, where it contributes to the innervation of the viscera, reaching all the way to the colon. Besides giving some output to various organs, the vagus nerve comprises between 80% and 90% of afferent nerves mostly conveying sensory information about the state of the body's organs to the central nervous system. The right and left vagus nerves descend from the cranial vault through the jugular foramina, penetrating the carotid sheath between the internal and external carotid arteries, then passing posterolateral to the common carotid artery. The cell bodies of visceral afferent fibers of the vagus nerve are located bilaterally in the inferior ganglion of the vagus nerve (nodose ganglia).

What is the vagus nerve?

The vagus nerve is the cranial nerve X (CNX) or your tenth cranial nerve. It is also known as the "wandering nerve" because it is the longest parasympathetic nerve in the body! It has been compared to the conductor of the orchestra because it takes the lead in almost every autonomic function in the body. Science has confirmed that the vagus nerve is the key to wellness as it stimulates the "rest and digest" side of our nervous system, as opposed to the sympathetic "fight or flight" side of the nervous system.

Which branch of the vagus nerve innervates the organs above the diaphragm?

The vagus nerve has two branches: the ventral vagus nerve and the dorsal vagus nerve, which are named because of where they originate from on the brainstem. The anterior vagal branch innervates the organs above the diaphragm, the heart and lungs, the back of the soft palate, some skin over the tragus of your ear, and more. The dorsal branch mainly innervates the organs below the diaphragm, including: the kidneys, liver, gallbladder, and the gut all the way down to the transverse colon.
