The spinal cord is a complex cylinder of nerves that starts at the base of your brain and runs down the vertebral canal to the backbone. It is part of the body’s collection of nerves, called the central nervous system, along with the brain. In each of the spinal cord’s many segments lives a pair of roots that are made up of nerve fibers. These roots are referred to as the dorsal (which is towards the back) and the ventral (which is away from the back) roots.
The spinal column is made up of 33 bones stacked on top of one another called the vertebrae. It provides the base support for your entire body and allows you to stand, bend, and twist without causing harm to the spinal cord.
