Your nervous system looks much like an upended tree, suspended from its roots at the base of your brain, its millions of limbs reaching out to every corner of your body.
Your spinal cord is like a thick braid formed by billions of these nerves. Your body has approximately 15 billion nerve cells-all of which receive and transmit nerve impulses by way of the spinal cord. These impulses control virtually all functions of your body-from your senses to mobility.
Nerve roots and your spinal cord
Your spinal cord actually ends near the base of your upper back, shooting out braids of nerves called “nerve roots.” These nerve roots run through a large tunnel-like canal, and at each level of your spinal column, a pair of nerve roots exits from the spine.
Nerve roots are named for the level of your spine they exit from, beginning with a letter and followed by a number. For example, a nerve root in the cervical spine may be called “C6,” while a nerve root in the lumbar region may be called “L4.”
Innate intelligence, the knowledge we are born with, guides cells and organs to receive and transmit impulses to our brain through this vast network of nerves.
A healthy spinal cord allows these impulses to flow freely back and forth. But when your spinal cord becomes misaligned, its parts get out of place and nerves can become pinched. When this happens, the flow of information from your nervous system gets interrupted. This imbalance, called subluxation, can lead to physical and emotional problems ranging from minor discomfort to major illnesses.
