Which vertebra is the largest in the spine?

• A. C3
• B. C4
• C. C1
• D. C2

Answer: (D)

Size varies along the spine, with the cervical region containing the smallest vertebrae and the lumbar region containing the largest to bear most of the body’s weight. Among the cervical vertebrae listed, the atlas (C1) has no vertebral body, so it isn’t the largest. The axis (C2) features a relatively large body and a distinctive dens, which generally makes it larger than the other cervical vertebrae shown. So, of the options given, C2 is the largest. It’s important to note that the truly largest vertebrae are in the lumbar region (typically L5), not in the cervical region.
