• B. 24
• C. 29
• D. 33

Answer: (D)

The total count of vertebrae in the human body is 33. This number includes several different regions of the spine: the cervical region has 7 vertebrae, the thoracic region contains 12, the lumbar region has 5, the sacrum (which is made up of 5 fused vertebrae) counts as a single structure, and the coccyx (commonly referred to as the tailbone, which comprises 4 fused vertebrae) also counts as one.

Adding these together gives a total of 33 vertebrae. Understanding this count is crucial for comprehending human anatomy, particularly in fields related to medicine, physical therapy, and chiropractic care, as it lays the foundation for discussions about spinal structure, function, and potential disorders.
