The Vertebral Column

Definition

The vertebral column, also known as the spine, is a series of vertebrae extending from the skull to the pelvis, which encases and protects the spinal cord while providing structural support and flexibility to the body. It is composed of individual bones separated by intervertebral discs that act as shock absorbers.
