The neck muscles regulates our blood flow of signals to the brain
An international team of researchers has discovered why problems can drive with the neck muscles in the affected blood pressure in the air: The muscles are connected with a m area of the brain, one of the key control points for autonomic functions such as blood pressure, respiration and heart rate influenced. Unusual signals from the muscles associated with this point, perhaps because of a strain or injury, have an impact, therefore, on blood pressure - a phenomenon that osteopaths, chiropractors and manual therapists in the past had always observed.
were already frequently it reports that by the rapid release of manipulative neck, commonly known as "straightening" known technical procedures, reduced the blood pressure of patients. Why this had happened yet, however, not known. Although scientists know already since a hundred years, the area of the brain, arriving in the signals of the neck muscles: It is a small part of the so-called metencephalon , ie, the brain area of the neck in the spinal cord passes. Where the impulses are relayed from there, had been scarcely investigated so far, said Jim Deuchars, one of the co-authors of the study.
In their work, the scientists analyzed now the metencephalon of rats and mice and found that it then links to a brain region called the nucleus tractus solitarii (NTS) is - both those the other nerve cells activate, as well as those that may inhibit other nerves. This is the link between neck muscles and the blood pressure found, the researchers explain, because the NTS had been previously associated with the regulation of breathing, blood pressure and heart rate related.
Such regulation of blood pressure on the neck muscles is according to scientists an important feature because the blood flow to the brain are held regardless of the current posture must always be consistent. Because the muscles in the neck while lying completely different will be charged as sitting or standing, they are particularly well suited for the brain changes communicate in attitude. Disturbances in this communication may be, for example, the cause of the dizziness, often caused by fast rising. You could also explain many of the complaints that frequently occur after a whiplash .
