An adult human ‘Spinal Support Engine’ has 24 vertebral bones, referred to as the ‘Pre or Supra Sacral Vertebrae’. At birth, the human spine consists of 33 individual irregularly shaped bones called ‘Vertebrae’. 9 of these fuse as the infant develops. I will identify these facets below.
Each of the 24 adult vertebra has a hole in the middle through which the spinal cord runs. These vertebral segments might remind you of boney and intra-cushioned structural donuts? Perhaps not? There are multiple small passageways through which the spinally sourced and branching nerves pass. The nerve that advises the brain that you have a tingly sensation or injured finger actually passes through or is branched from the Cervical or Neck Vertebrae. Anywhere you can feel anything below the base of your skull requires a nerve that transmits electro-chemical sensory to and through the Spinal Cord and column.
The spinal cord can be divided into five different regions, from top to bottom.
