  2. Microvillus - Wikipedia

    en.wikipedia.org/wiki/Microvillus

    Microvilli (sg.: microvillus) are microscopic cellular membrane protrusions that increase the surface area for diffusion and minimize any increase in volume, [1] and are involved in a wide variety of functions, including absorption, secretion, cellular adhesion, and mechanotransduction.

  3. Brush border - Wikipedia

    en.wikipedia.org/wiki/Brush_border

    Duodenum with brush border of microvilli. Illustration of the brush border membrane of small intestinal villi. A brush border (striated border or brush border membrane) is the microvillus-covered surface of simple cuboidal and simple columnar epithelium found in different parts of the body.

  4. Terminal web - Wikipedia

    en.wikipedia.org/wiki/Terminal_web

    The terminal web is a filamentous structure found at the apical surface of epithelial cells that possess microvilli.It is composed primarily of actin filaments stabilized by spectrin, which also anchors the terminal web to the apical cell membrane.

  5. Epithelium - Wikipedia

    en.wikipedia.org/wiki/Epithelium

    Epithelium or epithelial tissue is a thin, continuous, protective layer of cells with little extracellular matrix. An example is the epidermis, the outermost layer of the skin. Epithelial (mesothelial) tissues line the outer surfaces of many internal organs, the corresponding inner surfaces of body cavities, and the inner surfaces of blood vessels.

  6. Simple columnar epithelium - Wikipedia

    en.wikipedia.org/wiki/Simple_columnar_epithelium

    Absorptive columnar epithelium is characterized as having a striated border on its apical side, this border is made up of non-motile microvilli allowing for increase surface area for absorption. [1] These are known as non-ciliated columnar epithelium.

  7. Intestinal villus - Wikipedia

    en.wikipedia.org/wiki/Intestinal_villus

    Intestinal villi (sg.: villus) are small, finger-like projections that extend into the lumen of the small intestine.Each villus is approximately 0.5–1.6 mm in length (in humans), and has many microvilli projecting from the enterocytes of its epithelium which collectively form the striated or brush border.

    Prison would prove a nightmare for Sullivan. He had his nose almost bitten off in one attack and nearly lost an ear in another. And because he was a lifer, the prison system didn’t allow him to ...

  9. Intestinal epithelium - Wikipedia

    en.wikipedia.org/wiki/Intestinal_epithelium

    Drawing showing the relationship between villi and microvilli of the small intestine. The luminal surface of the enterocytes have microvilli (1 micrometer long) while the cell layer itself is folded to form villi (0.5-1.6 millimeters long) and crypts. Both serve to increase the total absorption surface of the intestine.
