What's In My Spine? 

Your spine is a column of 26 bones that extend in a line from the base of your skull to your pelvis. Twenty-four of these bones are called vertebrae. These link to each other and are cushioned by shock-absorbing disks that lie between them.

The vertebrae are organised as follows:

Neck - 7 cervical vertebrae

Chest - 12 thoracic vertebrae at the back wall of your chest;

Lower back - 5 lumbar vertebrae at the inward curve of your lower back;

The sacrum - composed of 5 fused vertebrae between your hip bones; and

The coccyx or tailbone - composed of 3 to 5 fused bones at the lower tip of your vertebral column

The vertebral column provides the main support for the upper body, allowing humans to stand upright or bend and twist, and it protects the spinal cord from injury. Following are structures of the spine most involved in spinal stenosis.

• Intervertebral disks—pads of cartilage filled with a gel-like substance which lie between vertebrae and act as shock absorbers.

• Facet joints—joints located on the back of the main part of the vertebra. They are formed by a portion of one vertebra and the vertebra above it. They connect the vertebrae to each other and permit back motion.

• Intervertebral foramen (also called neural foramen)—an opening between vertebrae through which nerves leave the spine and extend to other parts of the body.

• Lamina—part of the vertebra at the back portion of the vertebral arch that forms the roof of the canal through which the spinal cord and nerve roots pass.

• Ligaments—elastic bands of tissue that support the spine by preventing the vertebrae from slipping out of line as the spine moves. A large ligament often involved in spinal stenosis is the ligamentum flavum, which runs as a continuous band from lamina to lamina in the spine.

• Pedicles—narrow stem-like structures on the vertebrae that form the walls of the front part of the vertebral arch.

• Spinal cord/nerve roots—a major part of the central nervous system that extends from the base of the brain down to the lower back and that is encased by the vertebral column. It consists of nerve cells and bundles of nerves. The cord connects the brain to all parts of the body via 31 pairs of nerves that branch out from the cord and leave the spine between vertebrae.

• Synovium—a thin membrane that produces fluid to lubricate the facet joints, allowing them to move easily.

• Vertebral arch—a circle of bone around the canal through which the spinal cord passes. It is composed of a floor at the back of the vertebra, walls (the pedicles), and a ceiling where two laminae join.

• Cauda equina—a sack of nerve roots that continues from the lumbar region, where the spinal cord ends, and continues down to provide neurologic function to the lower part of the body. It resembles a "horse's tail"

What is Spinal Stenosis?

(1) the canal in the center of the column of bones (vertebral or spinal column) through which the spinal cord and nerve roots run, 

(2) the canals at the base or roots of nerves branching out from the spinal cord, or 

(3) the openings between vertebrae (bones of the spine) through which nerves leave the spine and go to other parts of the body. The narrowing may involve a small or large area of the spine. 

Pressure on the lower part of the spinal cord or on nerve roots branching out from that area may give rise to pain or numbness in the legs. Pressure on the upper part of the spinal cord (that is, the neck area) may produce similar symptoms in the shoulders, or even the legs.

Tips For Better Back Health

1. Stand upright and pay attention to posture – don't slouch
2. Sit back in your chair – don't hunch over your keyboard
3. Wear low-heeled and well-fitting shoes
4. Manage your weight – Extra weight, especially around your waist, strains your back
5. Do back exercises! Talk to your doctor about what types would be right for you
6. Do stomach-strengthening exercises! – Strong stomach muscles help support your back
7. Push rather than pull heavy objects
8. Change your position frequently
9. Use your leg muscles to lift heavy objects. Don't bend over and strain your back
