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

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

• Internal iliac nodes to submental nodes to cervical nodes
• Internal iliac nodes to common iliac nodes to lumbar nodes
• Internal iliac nodes to popliteal nodes to axillary nodes

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

• Pelvic organs have no regional lymphatics
• Lymph travels only inside arteries

• Common iliac nodes receive efferent lymph from internal iliac nodes
• The groups have no lymphatic connection

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