Q1. Why are tracheobronchial lymph nodes clinically important in lung cancer?
- They supply the lungs with arterial blood
- They are major pulmonary lymphatic collecting stations
- They produce pulmonary surfactant
- They innervate the bronchial tree
Q2. Which feature permits some pulmonary lymph to reach nodes on the opposite side?
- Communication between pulmonary arteries
- Cross connections between tracheobronchial pathways
- Direct continuity of the pleural cavities
- Fusion of the right and left main bronchi
Q3. Which tracheobronchial group is most closely related to the carina?
- Left superior group only
- Parasternal group
- Right superior group only
- Inferior tracheobronchial group
Q4. What is another clinically used term for the inferior tracheobronchial nodes?
- Subcarinal nodes
- Intercostal nodes
- Parasternal nodes
- Hilar nodes
Q5. Which sequence most accurately follows lymph from deep lung tissue toward a major collecting trunk?
- Diaphragmatic, bronchopulmonary, intercostal, parasternal
- Intercostal, pulmonary, diaphragmatic, parasternal
- Parasternal, pulmonary, intercostal, paratracheal
- Pulmonary, bronchopulmonary, tracheobronchial, paratracheal
Q6. Enlargement of inferior tracheobronchial nodes would occur near which airway junction?
- Tracheal bifurcation
- Pharyngoesophageal junction
- Laryngeal inlet
- Esophageal hiatus
Q7. Why can the tracheobronchial nodal pattern complicate predictions of lung tumor spread?
- All pulmonary lymph drains to axillary nodes
- Drainage can cross between right and left pathways
- The lungs contain no lymphatic vessels
- All lung lymph enters veins directly
Q8. Which nodes represent the major hilar station immediately before tracheobronchial drainage?
- Bronchopulmonary lymph nodes
- Intercostal lymph nodes
- Parasternal lymph nodes
- Diaphragmatic lymph nodes
Q9. Which major trunks form a terminal collecting pathway for lymph passing through tracheobronchial nodes?
- Subclavian trunks exclusively
- Intestinal trunk
- Lumbar trunks
- Bronchomediastinal trunks
Q10. Which description best summarizes the tracheobronchial lymph nodes?
- Nodes confined to the diaphragm
- Posterior nodes near the rib heads
- Peripheral nodes beside the sternum
- Central nodes around the main bronchi and carina
