Which artery's origin is commonly associated with the vertebral level L2?

• A. Celiac trunk
• B. Renal arteries
• C. Superior mesenteric artery
• D. Inferior mesenteric artery

Answer: (B)

Major abdominal arteries have characteristic origins along the aorta that map to specific vertebral levels. The renal arteries, which supply the kidneys, typically branch from the abdominal aorta at about the L1–L2 region. That makes their origin commonly associated with the vertebral level L2. In contrast, the celiac trunk branches off around T12, the superior mesenteric artery around L1, and the inferior mesenteric artery around L3. Thus, the level L2 is most classically tied to the renal arteries. Variations exist, but this is the typical pattern.
