The vagus nerve, the tenth cranial nerve, is really fascinating when you understand everything within the body that it is involved in. It runs from your brainstem down the whole length of the spine to the abdominal organs and innervates every organ along the way. It plays a major role in lowering the heart rate, breathing patterns, intestinal movement, sweating, and speech. It is your bodies off switch when feeling anxious and dealing with an overwhelming amount of stress, and the counterbalance to the fight or flight response. In another post I will talk about its connection to the enteric nervous system, our bodies "second brain", where our serotonin is secreted, packaged, and sent up to the brain via the vagus nerve.
