Which arteries originate as branches of the common iliac artery?

• A. Internal and External Iliac Arteries
• B. Radial and Ulnar Arteries
• C. Renal and Adrenal Arteries
• D. Gastric and Hepatic Arteries

Answer: (A)

In the pelvis, the common iliac artery divides into two main branches: the internal iliac artery, which supplies pelvic organs and the gluteal region, and the external iliac artery, which continues as the femoral artery to supply the lower limb. The other options come from different regions: the radial and ulnar arteries arise from the brachial artery in the arm; the renal and adrenal arteries come off the aorta to supply the kidneys and adrenal glands; and the gastric and hepatic arteries arise from the celiac trunk in the upper abdomen. Therefore, the arteries that originate as branches of the common iliac artery are the internal and external iliac arteries.
