  2. Basal cell - Wikipedia

    en.wikipedia.org/wiki/Basal_cell

    A basal cell is a general cell type that is present in many forms of epithelial tissue throughout the body. Basal cells are located between the basement membrane and the remainder of the epithelium, effectively functioning as an anchor for the epithelial layer and an important mechanism in the maintenance of intraorgan homeostasis.

  3. Phases of digestion - Wikipedia

    en.wikipedia.org/wiki/Phases_of_digestion

    Vagus nerve fibers from the medulla stimulate the parasympathetic nervous system of the stomach which, in turn, stimulates gastric secretion (via parietal and G cells). [1] This enhanced secretory activity brought on by the thought or sight of food is a conditioned reflex.

  4. Simple columnar epithelium - Wikipedia

    en.wikipedia.org/wiki/Simple_columnar_epithelium

    Simple columnar epithelium is a single layer of columnar epithelial cells which are tall and slender with oval-shaped nuclei located in the basal region, attached to the basement membrane. In humans, simple columnar epithelium lines most organs of the digestive tract including the stomach, and intestines.

  5. Intestinal epithelium - Wikipedia

    en.wikipedia.org/wiki/Intestinal_epithelium

    Cup cells are a distinct cell type that produces vimentin. [13] Tuft cells play a part in the immune response. [13] Throughout the digestive tract, the distribution of the different types of epithelial cells varies according to the function of that region. [5]

  6. Gastrointestinal physiology - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_physiology

    The digestive system has a complex system of motility and secretion regulation which is vital for proper function. This task is accomplished via a system of long reflexes from the central nervous system (CNS), short reflexes from the enteric nervous system (ENS) and reflexes from GI peptides working in harmony with each other. [4]

  7. Human digestive system - Wikipedia

    en.wikipedia.org/wiki/Human_digestive_system

    The pancreas is a major organ functioning as an accessory digestive gland in the digestive system. It is both an endocrine gland and an exocrine gland . [ 28 ] The endocrine part secretes insulin when the blood sugar becomes high; insulin moves glucose from the blood into the muscles and other tissues for use as energy.

  8. Intestinal gland - Wikipedia

    en.wikipedia.org/wiki/Intestinal_gland

    The basal (further from the intestinal lumen) portion of the crypt contains multipotent stem cells. During each mitosis , one of the two daughter cells remains in the crypt as a stem cell, while the other differentiates and migrates up the side of the crypt and eventually into the villus .

  9. Gastrointestinal wall - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_wall

    This controls peristalsis. Activity is initiated by the pacemaker cells (interstitial cells of Cajal). The gut has intrinsic peristaltic activity (basal electrical rhythm) due to its self-contained enteric nervous system. The rate can, of course, be modulated by the rest of the autonomic nervous system.
