Normal Spine

  • A disc is the shock absorber of the spine
  • It lies between the two adjacent bones called vertebral bodies
  • The nerves descend behind the vertebrae and discs
  • The back of the disc is in close proximity to the nerves
  • At each level the nerves give rise to 2 smaller nerves (one on each side) called nerve roots for their similarities to the roots of a tree
  • Several nerve roots on each side will converge and form the major nerves that descend to your legs like the sciatic nerve
