The initial bifurcation of the common iliac artery yields which pair?

• A. Internal and External Iliac Arteries
• B. Superior and Inferior Gluteal Arteries
• C. Deep Circumflex Iliac and Obturator Arteries
• D. Gastroduodenal and Right Gastric Arteries

Answer: (A)

The common iliac arteries divide into two main branches: the internal iliac and the external iliac. The internal iliac (hypogastric) artery supplies pelvic organs and adjacent structures, while the external iliac continues down to become the femoral artery after passing beneath the inguinal ligament. This makes the internal and external iliac arteries the correct result of the initial bifurcation. The other vessels listed come from different origins (branches of the internal iliac or from the celiac trunk) and are not the immediate split of the common iliac.
