How many total vertebras do you have?

An adult human typically has 33 vertebrae in total, which are divided into different regions: 7 cervical, 12 thoracic, 5 lumbar, 5 sacral (fused into the sacrum), and 4 coccygeal (fused into the coccyx or tailbone). However, variations can occur, leading to some individuals having one extra or one fewer vertebra.
