Protective layers of the spinal cord. At this segment nerve roots branch out from the spinal cord running from the lower back through the back of the leg and down to the toes. The vertebrae of the spine align so that their vertebral canals form a hollow bony tube to protect the spinal cord from external damage and infection.
