Q6. Which arteries can contribute to the inferior surface of the pericardium?
- Gonadal arteries
- Superior phrenic arteries
- Renal arteries
- Vertebral arteries
Q7. Why does the pericardium receive arterial branches from several sources?
- It has extensive thoracic relationships
- It is supplied only by coronary arteries
- It lies entirely in the abdomen
- It has no direct blood supply
Q8. Which vessels specifically supply the myocardium rather than the fibrous pericardium?
- Mediastinal branches
- Superior phrenic arteries
- Coronary arteries
- Pericardial branches
Q9. Which nearby aortic branches supply general posterior mediastinal tissues?

- Coronary arteries
- Mediastinal branches
- Common iliac arteries
Q10. Why are pericardial branches variable in number?
- They arise only after birth
- They arise from veins
- Their branching pattern is variable
- They disappear during systole
