The vertebral column is a major part of our central axis and also forms the vertebral column for the spinal cord. The vertebrae protect the spinal cord from damage. There are five distinct regions of the vertebrae that can be easily distinguished just by looking at the different structure of the vertebrae within each: cervical, thoracic, lumbar, sacral, coccygeal. There are a total of 33 vertebrae and here is the breakdown of how many are in each section: cervical 7, thoracic 12, lumbar 5, sacral 5, coccygeal 4. Each vertebrae is laballed based on the region and where it's found numerically. The first vertebrae is the first cervical vertebrae and then you just count up as you descend the column. For example, the 5th thoracic vertebrae would be called T5; the 4th cervical would be called C4.
