Intestine Histology Cartoon

Intestinal Villi Intestinal Crypts (crypts of Lieberkühn)
  • cover entire intestinal mucosa
  • about one mm long
  • increase the surface area by a factor of ~ ten.
  • villi surface formed by a simple columnar epithelium.
  • each absorptive cell or enterocyte of the epithelium forms numerous microvilli
  • openings of simple tubular glands
  • extend through the lamina propria down to the muscularis mucosae
  • undifferentiated cells close to the bottom of the crypts regenerate/replace the epithelium
    • epithelial cell turnover time is less than one week
  • other epithelial cells in the crypts correspond largely to those in the epithelium of the intestinal villi
  • Paneth cells are located at the bottom of the crypts
    • release a number of antibacterial substances (including lysozyme)
    • thought to be involved in the control of infections
