Origin

The branches of the vagus nerve to the carotid body originate either from the vagus nerve itself, or the inferior ganglion of the vagus nerve.

Course

The branches of the vagus nerve to the carotid body run from their origin down and towards the anterior surface of the internal carotid artery. Here they anastomose with the descending glossopharyngeal fibers of the carotid plexus, and particularly the carotid sinus nerve.

Branches

There are no named branches.

Supplied Structures

The branches of the vagus nerve to the carotid body are thought to convey sensation from a minor portion of the chemoreceptors in the carotid body. It is unclear if there is any functional significance to these fibers as the carotid body is largely innervated by the carotid sinus nerve from the glossopharyngeal nerve. Additionally, the branches of the vagus nerve to the carotid body are not always present (Toorop et al, 2009).

Vagus Nerve

ScienceDirect image

The vagus nerve is the 10th cranial nerve, is composed of both afferent (visceral sensory nerve) and efferent (motor nerve) fibers, and is an essential pathway in the regulation of food intake and energy metabolism (Berthoud and Neuhuber, 2000;
