The spine is made of thirty-three individual bones stacked one on top of the other. These vertebral bones include: seven cervical spine vertebrae located in your neck, twelve thoracic spine vertebrae located in your chest, five lumbar spine vertebrae located in your lower back, five fused sacral spine vertebrae and four fused coccygeal spine vertebrae located in your buttock region.
Ligaments and muscles connect the bones together and keep them aligned. The spinal column provides the main support for your body, allowing you to stand upright, bend, and twist. Protected deep inside the bones, the spinal cord connects your body to the brain, allowing movement of your arms and legs. Strong muscles and bones, flexible tendons and ligaments, and sensitive nerves contribute to a healthy spine. Keeping your spine healthy is vital if you want to live an active life without back pain.
