The most advanced communications system in the universe is that between the brain in our head and the rest of our body.  It is made up of billions of nerves "wires" that transmit information from our brain to every tissue of our body.  It's called our Nervous System.
 
It's amazing...
You live within an amazing miracle of  life called your body. It will serve you well as long as everything is working right.  Nerves supply the energy for your body to regenerate itself. The brain sends exact messages to every part of your body on what to do and how to to it.  If their is a blockage and messages cannot get through then degeneration begins and if continued long enough eventually can cause a slow death of that particular cell, tissue, organ, gland, etc.   If something is not right it may lead to serious problems. Your body has an amazing healing power, but it needs nerve energy to heal. A subluxation can block the needed nerve energy.

Most people are totally unaware that they have subluxations in their spine. That's because many nerves send no pain messages and are not composed of sensory fibers.  For example, you can feel something happen to your skin (which has full sensory nerves that send messages to your conscious brain), but not your liver (which has no sensory fibers going to the conscious brain).  When nerves not connected to the conscious brain are damaged, the brain doesn't feel any pain -- even though the nerve damage may be causing disease or physical malfunction.  That is why vertebral subluxations are often referred to as "silent killers".

The "Safety Pin" Cycle...
Brain Cells (BC) transfer energy pulses to Tissue Cells (TC) through the nerves telling the Tissue Cells what to do in EXACT quality and quantity.  The Tissue Cells then send an acknowledgment message.  This is how the body reproduces itself... IT'S HEALTH!
         

When there is a breakdown - a nerve blockage (a subluxation) - there is either no message received by the Tissue Cells or there is no acknowledgment received by the brain...  Degeneration begins and Cells die.
