The Spine

The vertebral column protects the spinal cord from injuries and infections, it supports the weight of our body helping us to stand up straight, it allows us to bend or twist our body.
Between the vertebrae as there are the intervertebral discs that act as shock absorvants in the spine and allow the spine to move.
