Explanation The vagus originates from the medulla oblongata region of the brain and exits the skull through the jugular foramen. In the neck region, the vagus nerve moves into the carotid sheath which is a fibrous connective tissue that surrounds the vasculature of the neck. It travels downwards along with the internal jugular vein and the carotid artery. The branches of the descending vagus nerve travel through different autonomic nerve plexus to reach various organs...

Chapter 15, Problem 18RQ

Summary Introduction

To review:

The route of vagus nerve through the neck, thorax, and abdomen.

Introduction:

Vagus is the tenth cranial nerve and the longest nerve of the autonomic nervous system. It contains parasympathetic fibers that innervate the abdomen and organs located in the thorax. It is responsible for the resting and the digestive activities such as constriction of bronchi and secretion of digestive enzymes by glands among other activities.
