Overview: mucosa
Simple columnar epithelium with microvilli lines the small intestine, possessing both absorptive (enterocytes) and mucus-secreting goblet cells. Villi, extending from the surface into the lumen, have a core of lamina propria covered by surface epithelium. Intestinal glands radiate peripherally from the bases of villi and extend to the muscularis mucosae. 200x
