How many total vertebrae are in the human adult spine?

Explanation:
The total vertebral count in the adult spine is 33 because the column is made of seven cervical, twelve thoracic, and five lumbar vertebrae, plus five sacral vertebrae that fuse into the sacrum and four coccygeal vertebrae that fuse into the coccyx. If you count all the original vertebral segments, you get 7 + 12 + 5 + 5 + 4 = 33. While the sacrum and coccyx fuse into single bones in adults, the standard count for vertebral segments remains 33.
