From the common iliac artery, what arteries arise?

• A. Internal and External Iliac Arteries
• B. Anterior Tibial and Posterior Tibial Arteries
• C. Lumbar and Sacral Arteries
• D. Phrenic and Hepatic Arteries

Answer: (A)

From the common iliac artery, two branches arise: the internal iliac artery and the external iliac artery. The internal iliac travels into the pelvis to supply pelvic organs and the gluteal region, while the external iliac continues downward and becomes the femoral artery after crossing beneath the inguinal ligament, supplying the lower limb. Other arteries listed belong to different regions: leg arteries come from the femoral/popliteal system, most lumbar and sacral arteries originate from the aorta or specific pelvic branches, and phrenic and hepatic arteries arise from the aorta or celiac trunk rather than directly from the common iliac.
