Q1. Which layer receives systemic arterial supply from pericardial branches rather than relying on coronary circulation?
- Myocardium only
- Interventricular septum only
- Endocardium only
- Fibrous and parietal pericardium
Q2. The visceral layer of serous pericardium receives its blood supply mainly from which vessels?
- Subcostal arteries
- Esophageal arteries
- Coronary arteries
- Posterior intercostal arteries
Q3. Which artery accompanies the phrenic nerve between the fibrous pericardium and mediastinal pleura?
- Pericardiacophrenic artery
- Bronchial artery
- Posterior intercostal artery
- Esophageal artery
Q4. Why may small pericardial branches be encountered during posterior mediastinal surgery?
- They enter the upper limb
- They drain the coronary sinus
- They supply adjacent posterior pericardium
- They supply the cerebral cortex
Q5. What may result from injury to a pericardial arterial branch?
- Cerebral edema
- Portal hypertension
- Local thoracic bleeding
- Renal infarction
Q6. Which feature best distinguishes pericardial branches from coronary arteries?
- They primarily supply myocardium
- They primarily supply pericardial tissues
- They run in coronary sulci
- They arise from the aortic sinuses
Q7. Which feature best describes the arterial supply of the fibrous pericardium?
- Multiple systemic arterial sources
- No arterial supply
- Pulmonary arteries only
- One terminal coronary artery
Q8. Why is the pericardiacophrenic artery generally more prominent than direct aortic pericardial branches?
- It supplies the entire myocardium
- It is a major consistent pericardial supplier
- It forms the coronary sinus
- It arises from the pulmonary trunk
Q9. Which arterial sources may anastomose within the pericardial blood supply?
- Coronary sinus tributaries only
- Pulmonary veins only
- Several neighboring systemic arteries
- Portal veins only
Q10. Which description best summarizes the direct pericardial branches of the thoracic aorta?
- Major coronary arteries
- Small variable visceral branches
- Terminal pulmonary arteries
- Large paired parietal arteries
