  2. Goblet cell - Wikipedia

    en.wikipedia.org/wiki/Goblet_cell

    The cells were first noted by Henle in 1837 when studying the lining of the small intestine, seen to be mucus producing by Leydig in 1857 (who was examining the epidermis of fish), and were given their name by Schulze in 1867, [24] [25] Schulze chose the descriptive name "goblet" because of the shape of the cell, rather than a functional name ...

  3. Intestinal epithelium - Wikipedia

    en.wikipedia.org/wiki/Intestinal_epithelium

    The intestinal epithelium is the single cell layer that forms the luminal surface (lining) of both the small and large intestine (colon) of the gastrointestinal tract. Composed of simple columnar epithelium its main functions are absorption, and secretion.

  4. Intestinal gland - Wikipedia

    en.wikipedia.org/wiki/Intestinal_gland

    Intestinal glands are found in the epithelia of the small intestine, namely the duodenum, jejunum, and ileum, and in the large intestine (colon), where they are sometimes called colonic crypts. Intestinal glands of the small intestine contain a base of replicating stem cells , Paneth cells of the innate immune system , and goblet cells , which ...

  5. Enterocyte - Wikipedia

    en.wikipedia.org/wiki/Enterocyte

    Enterocytes, or intestinal absorptive cells, are simple columnar epithelial cells which line the inner surface of the small and large intestines. A glycocalyx surface coat contains digestive enzymes. Microvilli on the apical surface increase its surface area.

  6. Gastrointestinal wall - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_wall

    The epithelium, the most exposed part of the mucosa, is a glandular epithelium with many goblet cells. Goblet cells secrete mucus, which lubricates the passage of food along and protects the intestinal wall from digestive enzymes. In the small intestine, villi are folds of the

  7. Paneth cell - Wikipedia

    en.wikipedia.org/wiki/Paneth_cell

    Paneth cells are cells in the small intestine epithelium, alongside goblet cells, enterocytes, and enteroendocrine cells. [1] Some can also be found in the cecum and appendix . They are located below the intestinal stem cells in the intestinal glands (also called crypts of Lieberkühn ) and the large eosinophilic refractile granules that occupy ...

  8. Gastrointestinal physiology - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_physiology

    Mucus is released in the stomach and intestine, and serves to lubricate and protect the inner mucosa of the tract. It is composed of a specific family of glycoproteins termed mucins and is generally very viscous. Mucus is made by two types of specialized cells termed mucous cells in the stomach and goblet cells in the intestines. Signals for ...

  9. Small intestine - Wikipedia

    en.wikipedia.org/wiki/Small_intestine

    The small intestine is the site where most of the nutrients from ingested food are absorbed. The inner wall, or mucosa, of the small intestine, is lined with intestinal epithelium, a simple columnar epithelium. Structurally, the mucosa is covered in wrinkles or flaps called circular folds, which are considered permanent features in the mucosa.
