Fig. 6. Histology of the mucosal epithelium of digesting snakes 2 days after
feeding. (A) Methacrylate-embedded section of the small intestine; Methylene
Blue/Thionine stain. Scale bar, 50 µm. The mucosal epithelium is a
single-layered columnar epithelium. (B) Methacrylateembedded section of the
small intestine; Methylene Blue/Thionine stain. Scale bar, 25 µm. Note the
large lacteals, blood-filled capillaries and lipid droplets in the
enterocytes. (C) Low-power electron micrograph of enterocytes filled with
lipid droplets. Scale bar, 2.5 µm. (D) High-power electron micrograph of
microvilli. Scale bar, 0.5 µm.
