Light and transmission electron microscopical observation of the liver structure of Melopsittacus undulatus

The liver structure of Melopsittacus undulatus is studied by light and transmission electron microscope.The results show that the liver lobules of Melopsittacus undulatus are irregular and unclear.Three to eight conglobation hepatocytes or the irregular hepatic cords line into a radiating shape surrounding the central vein.There are many mitochondria,endoplasmic reticulum,ribosomes and lysosome in the hepatocytes.The hepatocytes with double nucleui are abundant.The bile canaliculi are surrounded by adjacent hepatocytes.Junctional complex between the adjacent hepatocytes block out the bile canaliculi.Kupffer's cells and plasma cells are seen in the hepatic sinusiods.The space of Disse is clear.The hepatocytes protrude many microviuia facing the bile canaliculi and the space of Disse.
