This illustration represents spinal stenosis. The spinal column contains many vertebrae--each one stacked on top of the other. Between each vertebra are small joints that allow your spine to move and disks with jelly-like centers that act as shock absorbers and prevent your bones from rubbing against each other. During the natural aging process, these jelly like centers decrease in size from normal wear and tear and create what is called stenosis. Spinal stenosis occurs when the bones on both sides of the gel begin rubbing against one another. This is a major source of back pain.
