Q1. Which process explains increasing fatty appearance of the thymic region with age?
- Myocardial hypertrophy
- Pericardial calcification
- Age-related thymic involution
- Pleural fibrosis
Q2. Which statement correctly describes thymic tissue after fatty involution?
- Residual thymic tissue persists within fat
- The thymus enters the pericardial cavity
- All thymic tissue disappears at puberty
- The thymus becomes cartilage
Q3. Which fascial structure forms the posterior anatomical limit of anterior mediastinal fat?
- Visceral pericardium
- Endocardium
- Fibrous pericardium
- Prevertebral fascia
Q4. Which anatomical plane separates anterior mediastinal fat from the superior mediastinal region?
- Plane through the sternal angle and T4-T5 disc
- Subcostal plane
- Plane through the xiphisternum and T9
- Transpyloric plane
Q5. Which tissue type allows anterior mediastinal structures to be loosely packed rather than rigidly fixed?
- Hyaline cartilage
- Dense skeletal muscle
- Compact bone
- Loose connective tissue
Q6. Anterior mediastinal adipose tissue is external to which sac surrounding the heart?
- Endocardial sac
- Left ventricular cavity
- Coronary sinus
- Fibrous pericardial sac
Q7. Which feature helps distinguish anterior mediastinal fat from pericardial fluid anatomically?
- It fills the cardiac chambers
- It lies outside the pericardial sac
- It lies inside the myocardium
- It lies between serous pericardial layers
Q8. Which structures may be encountered within anterior mediastinal fat during dissection?
- Main bronchi and pulmonary arteries
- Esophagus and azygos vein
- Thymic remnants, lymph nodes, and small vessels
- Thoracic duct and descending aorta
Q9. Why can normal anterior mediastinal fat vary substantially among individuals?
- Age and body composition influence its amount
- It exists only during childhood
- Its amount is anatomically fixed
- It is produced by the pericardial cavity
Q10. Which statement best summarizes anterior mediastinal adipose tissue?
- A component of the posterior mediastinum only
- A serous layer covering the myocardium
- Fat located inside the cardiac chambers
- Normal fat often associated with thymic remnants
