2. LUMBAR SPINE
Your lumbar spine consists of the five vertebrae in your lower back. It provides
support for the weight of your body, surrounds and protects your spinal cord, and
allows for a wide range of body motions. Many conditions can affect this area of
your spine including lower back pain, arthritis, degenerative bone and disk disease
and stenosis.
3. WHAT IS THE LUMBAR SPINE?
Your lumber spine consists of the five bones (vertebra) in your lower back.
They are designated L1 to L5 starting at the top. The lumber vertebrae help
support the weight of the body and permit movement. They are the largest of
your entire spine. Your lumbar spine is located below your 12 chest(thoracic)
vertebra and above the five fused bones that make up your triangular-shaped
sacrum bone.
4. CON’T
Compared with other spine vertebrate, your lumbar vertebrae are larger, thicker and
more block-like bones. Your lumbar vertebrae provide stability for your back and
spinal column and allow for a point of attachment for many muscles and ligaments.
Your lumbar vertebrae support most of your body’s weight. It’s also the center of
your body’s balance.
Your lumbar spine and the muscle and ligaments that attach to them allow you to
walk, run, sit, lift and move your body in all directions.
Your lumbar spine has a slight inward curve called a LORDOTIC CURVE.
