Vertebra are the bones that make up the SPINE, also known as the vertebral column. The vertebral column is made up of 33 individual bones, which are divided into five sections. The first two sections are the cervical vertebrae, which are located in the neck region, and the thoracic vertebrae, which are located in the chest region. The third section is the lumbar vertebrae, which are located in the lower back region. The fourth section is the sacrum, which is a triangular bone located at the base of the SPINE. The fifth section is the coccyx, which is a small triangular bone located at the very bottom of the SPINE. The first two vertebrae, the ATLAS and the AXIS, are located in the cervical region and are responsible for allowing the head to move from side to side. The SPINE is made up of the remaining vertebrae, which provide support and stability to the body.
