The vagus nerve runs from the brain through the face and thorax to the abdomen. It is a mixed nerve that contains parasympathetic fibres. The vagus nerve has two sensory ganglia (masses of nerve tissue that transmit sensory impulses): the superior and the inferior ganglia.

When we move, the digestive system is stimulated, and the peristaltic wave which moves stool through the colon is also activated. This movement is controlled in part by the vagus nerve, which is also stimulated by exercise, from walking to yoga to crossfit.

Can a hiatal hernia stimulate the vagus nerve?

In our patient, the intrathoracic pressure from a hiatal hernia, precipitated by swallowing, resulted in intense vagal nerve stimulation causing sinus node slowing, followed by sinus arrest and the transient syncopal episodes.

Where is the vagus nerve located in the ear?

(A) The vagus nerve (VN) connects the brain with most of the organs within the thorax and abdomen. Afferent auricular branches (aVN) leave the cervical VN at the level of the jugular ganglion just outside the cranium and innervate the rather central regions of the pinna of the outer ear (Peuker and Filler, 2002).
