Q6. Why does visceral pleura move directly with the lung during respiration?

• It is firmly adherent to the lung
• It is attached to the ribs
• It is fused to the diaphragm
• It contains skeletal muscle

Q7. Which autonomic pathway contributes fibers to the pulmonary plexus?

Q9. Sharp pleuritic pain suggests inflammation has involved which layer?

• Parietal pleura
• Bronchial cartilage
• Visceral pleura alone
• Pulmonary alveoli only

Q10. Which pleural reflection forms a double layer inferior to the lung root?

• Pulmonary ligament
• Costodiaphragmatic recess
• Costomediastinal recess
