Neurergus microspilotus (10.3897-zoologia.34.e13229) Figures 5–8

Description:

Figures 5–8; Liver of N. microspilotus. (5) The liver tissue demonstrates the sponge-like appearance of the parenchyma, which is composed of polyhedral hepatocyts. Numerous dark brown spots are small melanomacrophage centers (H&E, ×1000). (6) Cords of hepatocyte separated by sinusoids (arrows) containing erythrocyte. Hepatocytes are large cells with central nuclei (H&E, ×4000). (7) Central vein (*) and intrahepatic ducts (arrow) are seen in this picture (H&E, ×2500). (8) Liver parenchyma (PAS, ×1000). One of the liver’s most metabolic functions is storage of glycogen. At this high magnification, one can see that the hepatocytes are strongly stained in magenta by the PAS method; this reaction reveals the presence of red granules including glycogen.
