<Explanation>
It’s likely that ancient anatomists gave this nerve the strange name of the vagus nerve because they didn’t know where it went, since it goes to all the internal organs.The vagus nerve is also the boss of the parasympathetic nervous system throughout the body. It seems that most symptoms of autonomic nervous system imbalance can be explained by a decrease in the function of the vagus nerve.
The important thing to note here is that it is said that the function of the autonomic nervous system is to send much more information (70-80%) from the internal organs to the brain (called afferent fibers) than from the information sent from the brain to the internal organs (called efferent fibers).
But why do symptoms occur in the eyes and ears inside the head that have nothing to do with the neck?
That’s the most important part of solving the mystery. To solve the mystery, it’s easy to understand if you think about the evolutionary process of living things.
The parasympathetic nerves (which control the pupils, tear glands, saliva, Eustachian tubes, and eardrum vibrations) in the skull and the vagus nerve are now called different nerves, but they were originally one nerve. When the neck muscles become stiff and the function of the vagus nerve declines, symptoms such as glare, dry eyes, and ear congestion occur.And finally, it leads to depression, which has recently become a rapidly increasing social problem.
