The thoracic spine (upper back) and lumbar spine (low back) consist of 17 stacked vertebrae, with disks between them to absorb shocks. Nerves emerge from the spinal cord to “activate” parts of the body. The low back helps you stand upright and maintain balance as you bend over or lift heavy objects, while the upper back anchors the ribcage and protects the heart and lungs. Both areas are influenced by postures and activities in which we engage. Sitting for long periods (for work and driving) is often more stressful to the back than more physical activities.
