The human spine plays an extremely important role in our bodies as it supports the upper body’s weight; provides posture while allowing for movement and flexibility; and protects the spinal cord.
The vertebrae are connected to each other through intervertebral discs. Each disc forms a joint to allow movement of the spine.Between the vertebrae are small spaces known as intervertebral canals that allow spinal nerves to exit the spinal cord and connect to the various regions of the body.
