As shown in this rotating model, the anatomy of the spine is composed of three major sections: the cervical, the thoracic, and the lumbar regions. Below the lumbar region is the sacrum, which is part of the pelvis. Individual bones called vertebrae make up each section. There are 7 cervical, 12 thoracic, and 5 lumbar vertebrae.
