Lumbar Spine

The lumbar spine refers to the lower part of the back, consisting of five vertebrae labeled L1 through L5. It is situated between the thoracic spine (mid-back) and the sacrum (tailbone) and supports much of the body's weight. The lumbar region is crucial for mobility and stability, allowing for bending, twisting, and lifting. It also houses spinal nerves that branch out to lower limbs and organs. Common issues in the lumbar spine include muscle strain, herniated discs, and sciatica, often leading to pain and discomfort in the lower back. Proper posture and exercise can help maintain its health.
