Which spinal section has seven vertebrae?

• A. Cervical
• B. Thoracic
• C. Lumbar
• D. Sacral

Answer: (A)

Vertebral counts vary by spinal region, and seven vertebrae are found in the neck portion of the spine. This cervical region contains C1 through C7, with the first two vertebrae (the atlas and axis) offering specialized functions for head support and rotation. The thoracic region has twelve vertebrae, the lumbar region five, and the sacral region consists of five vertebrae fused into the sacrum. So seven is the defining count for the cervical region.
