The discs also provide space between the vertebrae. This is important because nerves pass through the spaces that are created by the discs. Discs also act as a shock absorbers. When movement occurs, the jelly solution inside the disc has the ability to expand and compress. If the spine become misaligned, a disc can become buldged or herniated. In some cases it may even rupture. A misalignment is not the only cause for this problem. Age can cause the disc to become weak and dehydrated.
