The Spine has five major sections
Cervical - the top seven vertebrae which make up the neck
Thoracic - the twelve vertebrae connected to the ribs
Lumbar - the heaviest five vertebrae which support the torso
Sacrum - a large, dish-like bone, made up of the sacral vertebrae, which have fused solidly together to make up the connection of the spine to the pelvis
Coccyx - the vestigial tailbone is made up of 3 to 4 fused vertebrae
