Q3. Which portion of the rectum can drain toward internal iliac lymph nodes?

• Transverse colon only
• Ascending colon only

• Cecum only

Q4. Which statement best describes lymphatic drainage of the uterine cervix?

• It has no lymphatic drainage
• It drains exclusively to popliteal nodes
• It drains exclusively to axillary nodes
• It drains through multiple pelvic nodal pathways including internal iliac nodes

Q5. Why are internal iliac nodes clinically important in pelvic malignancies?

• They are located only in the upper limb
• They form the pelvic diaphragm
• They receive lymph from several pelvic viscera
• They drain only the scalp

Q6. Which sequence represents a common direction of lymph flow from internal iliac nodes?

• Internal iliac nodes to submental nodes to cervical nodes
• Internal iliac nodes directly to the portal vein
• Internal iliac nodes to popliteal nodes to axillary nodes
• Internal iliac nodes to common iliac nodes to lumbar nodes

Q7. Why can one pelvic organ drain to both internal and external iliac nodes?

• Every pelvic organ has only one lymphatic vessel
• Pelvic lymphatic pathways often overlap
• Pelvic organs have no regional lymphatics
• Lymph travels only inside arteries

Q8. Which internal iliac branch territory is associated with obturator lymph nodes?

• Superior mesenteric territory
• Obturator vascular territory
• Axillary vascular territory
• External carotid territory

Q9. What is the relationship between internal iliac and common iliac lymph nodes?

• Common iliac nodes drain into popliteal nodes
• Common iliac nodes receive efferent lymph from internal iliac nodes
• The groups have no lymphatic connection
• Internal iliac nodes receive all lymph from axillary nodes

Q10. Which principle helps explain the distribution of internal iliac lymph nodes?

• Lymphatics always avoid blood vessels
• Lymphatics travel only with cranial nerves
• Lymphatics commonly follow vascular pathways
• All pelvic lymphatics immediately enter the thoracic duct
