Notes
The villi of the small intestine are lined by simple columnar epithelium composed primarily of absorptive cells (enterocytes), with scattered goblet cells.
Mucus in goblet cells stains poorly with H&E. In this micrograph, goblet cells appear as pale spots (blue arrowheads).
For PAS stain highlighting mucus in goblet cells, click on thumbnail image at right.
(Enteroendocrine cells also occur in the intestinal epithelium, but none can be readily discerned on this micrograph.)
Lamina propria forms the core of each villus and contains a single lacteal.
