How many sections does the vertebral column have?

• A. Two
• B. Four
• C. Five
• D. Three

Answer: (D)

The vertebral column is organized into regional segments along its length. There are five regions: cervical (neck), thoracic (mid-back), lumbar (lower back), sacral (sacrum), and coccygeal (coccyx). Each region corresponds to a set of vertebrae, with the sacrum and coccyx typically fused in adults. Even though the bones may fuse, the spine is still described as having five sections.
