The spinal canal is a triangular-shaped structure with boundaries made up of bones, ligaments and discs.
Dr. Luis Lombardi-Spinal Canal
-
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
