Fine structure of the esophagus lining epithelials cells of the snake Xenodon merremii Wagler, 1824 (Ophidia).

The authors studied the ultrastructure of the esophagus lining epithelial cells of the snake Xenodon merremii. The initial shows ciliated wedge shaped cells and goblet cells which are gradually displaced by columnar ones in the posterior third of the organ. Other cellular types, such as basal, argentaffin and argyrophil cells can be found throughout the esophagus mucosa.
