How many cervical vertebrae are there in the spine?

Explanation:
Seven vertebrae make up the cervical region of the spine. This region is defined by a fixed count in human anatomy, with seven vertebrae labeled C1 to C7. The neck portion is the most mobile, and the first two vertebrae (atlas and axis) enable the head to nod and twist. Because the cervical region reliably contains seven vertebrae, that is the correct count. The mid-back has twelve thoracic vertebrae, the lower back has five lumbar vertebrae, and the tailbone area comprises fused sacral and coccygeal bones, which account for other numerical options.
