Which vertebral levels comprise the cervical region of the spine?

• A. T1-T12
• B. C1-C7
• C. S1-S5
• D. L1-L5

Answer: (B)

The cervical region is defined by seven vertebrae in the neck, labeled C1 through C7. The first two, C1 (the atlas) and C2 (the axis), have special roles in head movement—C1 supports the skull, and C2 has the dens that enables rotation. The rest of the regions are defined by their own ranges: the thoracic region is T1-T12, the lumbar region is L1-L5, and the sacral region is S1-S5. So the cervical region corresponds to C1-C7.
