  3. Line of attachment of falciform ligament of liver
  4. Hepatic vein (cut off)
  5. Upper pointer: Vena caval foramen Lower pointer: Inferior vena cava (cut off)
  6. Branches right phrenic nerve
  7. Phrenic arteries
  8. Right pointer: Duodenal suspensory muscle (cut off near attachment to right crus of diaphragm) Left pointer: Greater splanchnic nerve (celiac ganglion removed)
  9. Right pointer: Right crus lumbar part diaphragm Left pointer: Lumbocostal arch (arcuate ligament)
  10. Intervertebral disc L. II-III
  11. Upper pointer: Costal pleura (fascia in vertebrocostal triangle removed) Lower pointer: Fascia forming lateral lumbocostal arch
