Detailed explanation-1: -The lumbar spine comprises the lower end of the spinal column between the last thoracic vertebra (T12) and the first sacral vertebra (S1). The spinal cord in this region has protection from five durable and mobile vertebrae (L1-L5) that allow for the dispersion of axial forces.

Detailed explanation-2: -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. Compared with other spine vertebrae, your lumbar vertebrae are larger, thicker and more block-like bones.

Detailed explanation-3: -Thoracic (mid back)-the main function of the thoracic spine is to hold the rib cage and protect the heart and lungs. The twelve thoracic vertebrae are numbered T1 to T12. The range of motion in the thoracic spine is limited. Lumbar (low back)-the main function of the lumbar spine is to bear the weight of the body.

Detailed explanation-4: -However, transition areas are often forgotten and shouldn’t be! The thoracic and lumbar spine (T12/L1) connect at one of the most important locations in the body and is referred to as the thoracolumbar joint.
