The spinal cord is a soft bundle of nerves that extends from the base
of the brain to the lower back. It runs through the spinal canal and is
protected by the bones of the spine (vertebrae). Messages between the brain and
the nerve roots travel up and down the spinal cord, making it possible for the
brain and body to communicate. The discs cushion the vertebrae and provide
flexibility to the spine and spinal cord.
