Thoracic And Lumbar Vertebra

The thoracic and lumbar vertebrae are two regions of the vertebral column (spine) that support the upper body, protect the spinal cord, and allow for various movements. The thoracic vertebrae are the twelve vertebrae in the middle and upper back regions. They are designated as T1 to T12. The primary function of the thoracic vertebrae is to provide stability and support for the rib cage and protect the vital organs in the chest. The lumbar vertebrae refer to five vertebrae located in the lower back region. They are designated as L1 to L5. The lumbar vertebrae bear a significant amount of weight and support the upper body, maintain posture, and facilitate movements such as bending, twisting, and lifting.
