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
