What you need to know about the "Slipped Disc
Understanding the spine
The spine is made up of many bones called vertebrae. These are roughly circular and between each vertebra is a disc. The discs are made of strong rubber-like tissue, which allows the spine to be fairly flexible. A disc has a stronger fibrous outer part, and a softer jelly-like middle part called the nucleus pulposus.
The spine protects the spinal cord, which contains the nerves that come from the brain. Nerves from the spinal cord come out from between the vertebrae to take and receive messages to various parts of the body. Strong ligaments attach to the vertebrae. These give extra support and strength to the spine. Various muscles also surround, and are attached to various parts of the spine.
