Spine and spinal nerves,computer artwork 插畫檔

Lower part of the human vertebral column (blue) showing the spinal nerves (mauve) and intervertebral discs (yellow).Through the spinal nerves messages from the brain to the body and from the body to the brain are relayed. If a discs bulge out and presses against the spinal cord or one of its nerve branches, pain and numbness are typical symptoms. In rare cases damage to the spinal cord can cause partial paralysis.
