Intermediate External Iliac Nodes Quiz

Q1. Which three positional subgroups are commonly described for external iliac lymph nodes?

• Lateral, intermediate, and medial chains
• Superior, inferior, and central cervical chains
• Superficial, deep, and terminal axillary chains
• Anterior, posterior, and apical chains

Q2. Which external iliac subgroup is often associated with nodes near the obturator region?

• Occipital chain
• Submental chain
• Medial chain
• Lateral chain

Q3. Which lymph nodes can receive drainage from the upper vagina?

• Submental and occipital nodes
• Popliteal and axillary nodes
• External and internal iliac nodes
• Epitrochlear and cervical nodes

Q4. Which statement best describes cervical lymphatic drainage involving external iliac nodes?

• External iliac nodes can receive some cervical lymphatic drainage
• All cervical lymph drains only to popliteal nodes
• The cervix drains only to axillary nodes
• The cervix has no lymphatic vessels

Q5. Why are external iliac nodes important in pelvic cancer staging?

• They directly produce lymphocytes for the thymus
• They are the only lymph nodes in the body
• They drain the entire upper limb
• They receive lymph from several pelvic organs

Q6. Which sequence correctly represents lymph flow through the external iliac pathway?

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

Q7. Which anatomical landmark marks the transition between external iliac and femoral vessels?

• Linea alba
• Greater sciatic foramen
• Inguinal ligament
• Sacrotuberous ligament

Q8. Which bladder region is particularly associated with external iliac lymphatic drainage?

• Only the renal pelvis
• Only the adrenal gland
• Only the urethral meatus
• Superior and upper bladder regions

Q9. Why can one pelvic organ drain to both external and internal iliac nodes?

• Pelvic organs lack regional lymphatics
• All lymphatic vessels terminate in one node
• Pelvic lymphatic drainage pathways overlap
• Lymph flows only within veins

Q10. What is the relationship between external iliac nodes and common iliac nodes?

• Common iliac nodes drain into popliteal nodes
• Common iliac nodes receive efferent lymph from external iliac nodes
• The two groups are unrelated
• External iliac nodes receive all lymph from axillary nodes
