Advanced Mediastinal Lymph Nodes Quiz

Q1. Which lymphatic trunks ultimately receive much of the lymph from thoracic lymph nodes?

• Intestinal trunk
• Lumbar trunks
• Bronchomediastinal trunks
• Jugular trunks only

Q2. Where do the bronchomediastinal trunks ultimately drain?

• Portal vein
• Coronary sinus
• Near the venous angles
• Inferior vena cava

Q3. Which nodes provide an important alternative drainage route for the medial breast?

• Parasternal nodes
• Popliteal nodes
• Superficial inguinal nodes
• Preaortic nodes

Q4. Why are parasternal nodes clinically important in breast malignancy?

• They receive medial breast lymphatics
• They form the pectoral fascia
• They produce breast hormones
• They directly supply breast arteries

Q5. Which anatomical relationship allows lymphatic communication across the anterior thorax?

• Interventricular communications
• Parasternal lymphatic connections
• Coronary arterial anastomoses
• Pulmonary venous connections

Q6. Which nodes are positioned near the anterior surface of the pericardium?

• Lumbar nodes
• Posterior mediastinal nodes
• Celiac nodes
• Anterior mediastinal nodes

Q7. Which thoracic lymphatic pathway is most relevant to spread from medial breast tissue?

• Iliac pathway
• Parasternal pathway
• Mesenteric pathway
• Popliteal pathway

Q8. Why can mediastinal lymph nodes be important in cancer staging?

• They control diaphragmatic contraction
• They can receive metastatic tumor cells
• They determine cardiac rhythm
• They regulate aortic pressure

Q9. Which statement best describes the relationship of anterior mediastinal nodes to the pericardium?

• They lie only behind the vertebral column
• They lie within the myocardium
• They lie inside the cardiac chambers
• They may lie anterior to the fibrous pericardium

Q10. Which statement best summarizes anterior mediastinal lymph nodes?

• They are located within the heart
• They function as endocrine glands
• They drain only the lower limb
• They drain nearby thoracic structures
