How many vertebrae are in the human spinal column?

The human spinal column consists of a total of 33 vertebrae, which includes various regions with differing numbers of vertebrae. The cervical region contains 7 vertebrae, the thoracic region has 12, the lumbar region has 5, and the sacral region is comprised of 5 fused vertebrae, followed by the coccygeal region, which has 4 fused vertebrae, typically forming the tailbone. This total adds up to 33 vertebrae.

It’s important to note that while 24 is a common figure referring only to the movable vertebrae (cervical, thoracic, and lumbar), the complete count including the fused vertebrae in the sacrum and coccyx brings the total to 33. This understanding is fundamental for comprehending the overall structure and function of the vertebral column in the human body.
