Q1. Which feature best distinguishes mediastinal branches from posterior intercostal arteries?
- They occur only in the abdomen
- They are visceral rather than parietal branches
- They arise from veins
- They contain deoxygenated blood
Q2. Why may mediastinal branches be encountered during posterior mediastinal surgery?
- They cross the cranial cavity
- They supply the kidney
- They supply local mediastinal tissues
- They enter the upper limb
Q3. What is a potential consequence of injury to a mediastinal arterial branch?
- Mediastinal bleeding
- Renal failure
- Portal hypertension
- Cerebral infarction
Q4. Why can the exact anatomy of mediastinal branches differ between patients?
- They originate from lymphatics
- They are fetal vessels
- They form only after surgery
- Natural vascular variation
Q5. Which imaging method can depict small arterial branches arising from the thoracic aorta?
- CT angiography
- Electrocardiography
- Bone densitometry
- Dental radiography
Q6. Which statement best describes the origins of mediastinal branches?
- Small irregular branches from the thoracic aorta
- Terminal branches of the coronary arteries
- One constant branch from the pulmonary trunk
- Paired branches from the abdominal aorta
Q7. Which arterial branches may overlap with mediastinal branches in supplying nearby thoracic tissues?
- Bronchial, esophageal, and pericardial branches
- Anterior tibial and fibular branches

Q8. Which feature makes mediastinal branches less prominent in gross anatomy than intercostal arteries?
- Absence of arterial blood
- Location inside the heart
- Presence only before birth
- Small size and variable pattern
Q9. During aortic surgery, why should small mediastinal branches be recognized?
- To prevent or control bleeding
