Firstly, the spine is separated into three separate types of vertebrae: the first seven starting at the base of the skull are the cervical vertebrae (and the first specifically being the atlas and second the axis), the next twelve are the thoracic vertebrae, and the last five are the lumbar vertebrae. The spine ends with the large sacrum bone and then ends with the coccyx (tailbone). between these vertebrae are disks of hyaline cartilage.

The vertebral column houses the spinal cord. The spinal cord branches out between each vertebrae with nerves that lead to different areas of the body.
