Colon, mucosa

Notes

The mucosa of the colon is characterized by straight crypts with no villi.

Unless specially stained, the mucus in goblet cells appears as clear "bubbles" in crypt epithelium.  But note that epithelial nuclei are more numerous than the mucus blobs, indicating that absorptive cells remain the predominant cell type in colon epithelium (as also in the small intestine), even though they are crowded by goblets and hence inconspicuous.
