The Vagus nerve, also known as the 10th cranial nerve is one of the most important nerves on the body. What does it control? How about nearly every organ! When this important nerve is not functioning properly, it can result in problems throughout the body. Fortunately, there are several methods within Applied Kinesiology (AK) to test for and improve Vagus nerve function.

Most of the nerves in the body travel down the spine and exit at various levels to supply muscles and organs. The spinal nerves that go to the organs are part of the Sympathetic Nervous System. You can think of this as the “get up and go, fight or flight” part of the nervous system. There are 12 nerves, called “cranial nerves” that start in the brain exit through openings in the skull and travel to various areas to create their effect. The 10th cranial nerve, aka Vagus, exits the skull and then goes…..all over the place in the chest and abdomen.

The Vagus nerve is the primary part of the Parasympathetic Nervous System. You can think of this as the “slow down, relax, regenerate, grow, heal” part of the nervous system. The Vagus nerve supplies the larynx, heart, lungs, liver, gallbladder, stomach, spleen, small and large intestines (except for the last bit of the large intestine which is supplied by sacral nerves), kidneys. Vagus nerve function is especially key for digestive and gut function.
