Which root means lower back?

• A. Head
• B. Chest
• C. Knee
• D. Lower Back

Answer: (D)

The concept here is connecting a root to the body region it names. The root for the lower back is lumb/o (from Latin lumbus). It shows up in terms describing the lumbar region of the spine, such as lumbar or lumbosacral. Because this root specifically denotes the lower back, the correct choice is the one that names that region. The other areas—head, chest, and knee—have different roots (cephal- or crani- for head, thorac- for chest, patell- or genu- for knee), so they don’t indicate the lower back.
