In this article we are going to look in some detail at the Vagus nerve which is the longest of the cranial nerves . Vagus is latin for “wandering” and it describes the path this nerve takes through the body. Actually while classed as just one, it is actually two nerves that extend from the cerebellum and brain stem and down into the viscera and on the way it connects to the heart and all major organs and so could be considered largely responsible for the mind-body connection.
