Nerves are like the bundle of cables that are used to run the computer. They might all look the same, but each cable has a unique function.
A Nerve Division is a single cable in the bundle that starts at the nerve root and travels the full length of the nerve with a specific purpose in mind. Motor neurons within a division are responsible for sending contraction signals to muscles for motion. Nerve Branches are extensions of the Division to reach out to muscles in a group. A specific action is defined within a Nerve Division and communicated to muscles via Nerve Branches.
If the power cable to the monitor is pinched, the monitor might flicker, or the monitor might flicker if the cable connecting it to the computer is loose, or the monitor might flicker if there is something wrong with the internal wiring of the machine. Muscles and nerves can have a similar variety of issues. The nerve supporting a muscle might be in trouble from the nerve root. The nerve pathway itself could be impinged somewhere along the way. The fibers of the muscle might not be able to receive a nerve signal.
When there is a stressful situation, nerves are called upon to help manage the emergency, and a whole new set of signals is sent from the sympathetic nervous system.
In Ayurvedic Medicine, a 5000 year old doctrine from India, it is said that the nervous system is supported by the lymphatic system, a vast delivery network of lymph or fluid in plasma cells that acts as a sweeper for anything outside of the vascular system. Lymphatic fluid, containing white blood cells made in the bone marrow, is filtered through lymph nodes which retain anything strange in a holding cell until it can be evaluated in an immunity check. Junk is sent for removal in the waste system. Useful fluid is returned to the heart to be recycled including fats and proteins from the intestines. The vascular, nervous and lymphatic systems travel together throughout the body in close proximity to each other as there are only so many holes that can be used to pass through bones to get around. So how does the lymphatic system support the nervous system?
The stress hormone, epinephrine or adrenalin, is a neurotransmitter sent from the adrenal glands for carbohydrate metabolism needed for a host of power exertion requirements for stress. The easiest place to get carbs is from inside muscles. Note: Anabolic steroids store fuel to make big muscles. Corticosteroids, such as adrenalin, take fuel out of muscles for stress energy management. The anti-inflammatory property of corticosteroids may. be the reduction in the fuel storage inside water based solutions.
After muscles are depleted, the next place to get fuel would be from inside the lymphatic system by hijacking a plasma truck loaded with fuel headed from the intestines to the heart to redistribute the fuel into the vascular system. Stress needs to delivery lots of fuel to the vascular system, so it would not make sense to take that fuel to just put it back. The stress neurotransmitters gather fast fuel from the fats and proteins inside the lymphatic system. Belly fat and other fat deposits close to the skin are easily accessible by adrenalin via the nervous system, supported by the lymphatic system, which is literally right next to it in the traffic lanes of vessels routed together. The vascular system has 49% red blood cells and 51% plasma cells. Plasma cells have a semi- permeable membrane, and water soluble nutrients cross in and out of the cell walls by equalizing fluid concentrations from inside and outside the cell in osmosis. The adrenalin can mobilize the fuel inside the lymphatic system, and the vascular system can easily absorb it into its plasma cells, fast and furious from the fight or flight sympathetic nervous system call to action.
Adrenalin can be released from the nervous system at the nerve terminals. If there is a disturbance to the nerve line, sometimes the tissue in the area of the nerve terminal can swell into a bump to protect against the barrage of out of control hormone release.
Stress in a short term emergency can be a powerful tool to mobilize resources and deal with an immediate crisis. Long term stress can be a very complicated restructuring of resource management in the body involving the vascular, nervous and lymphatic systems. In stress, digestion and immunity is turned off to allow the intense resources needed for those processes to be redirected to stress management. The body can manage on a diet of life support through stress energy – until it can’t.
