Dissection of pericardium and heart in situ
Latex cast of cavities of right atrium and right ventricle
The anterior walls of the right atrium, right ventricle, conus arteriosus and pulmonary trunk have been cut away to reveal a blue latex cast which fills the interior of these chambers. Impressions in the cast produced by muscle trabeculae are clearly visible. Casts of several anterior cardiac veins (9) have been dissected free in removing the wall of the heart and are visible attached at their points of entry into the right atrium.
  1. Superior extent of pericardial cavity
  2. Phrenic nerve
  3. Superior vena cava
  4. Upper pointer: Right auricle (epicardium and myocardium intact) Lower pointer: Latex cast of right auricle
  5. Right coronary artery (cut off)
  6. Margin of right atrioventricular opening
  7. Cast of right atrium
  8. Cast of right atrioventricular opening
  9. Anterior cardiac veins
  10. Myocardium of right ventricle
  11. Left vagus nerve
  12. Ascending aorta
  13. Latex cast of sinus of anterior cusp of pulmonary valve
  14. Pericardium
  15. Latex cast of conus arteriosus
  16. Anterior interventricular sulcus
  17. Left ventricle
  18. Latex cast of right ventricle
