Which vessels arise directly from the common iliac artery to supply pelvic structures?

• A. Internal and External Iliac Arteries
• B. Lesser Omentum Artery
• C. Gastric Artery
• D. Sphenopalatine Artery

Answer: (A)

From the common iliac artery, the two main branches are the internal iliac and the external iliac. The internal iliac is the primary supplier of pelvic organs and pelvic walls, delivering blood through its many pelvic branches. The external iliac, while mainly the path highway to the lower limb (becoming the femoral artery), has smaller branches that can contribute to the pelvic region as well. Because both arteries originate directly from the common iliac and participate in pelvic perfusion, they are the vessels that arise from the common iliac to supply pelvic structures. The other arteries listed supply regions outside the pelvis (stomach and head/face) and don’t serve as pelvic feeders.
