In cells such as those lining the small intestine, apical surfaces are densely covered with uniform microvilli, which are visible as a brush or striated border on these cells (Figure 4–8). The average microvillus is about 1 μm long and 0.1 μm wide, but with hundreds or thousands present on the end of each absorptive cell, the total surface area can be increased by 20- or 30-fold.

It is customary to take note of the surface specializations of epithelia, which allow them to perform their function as a selective permeability barrier. These specializations can be located on one of the three surfaces of an epithelial cell. Apical Specializations Glycosylphosphatidylinositol (GPI)-anchored proteins (GPI-APs) are a class of membrane proteins containing a soluble protein attached by a conserved glycolipid anchor to the external leaflet of the plasma membrane. In polarized epithelial cells, GPI-APs are predominantly sorted to the apical surface … 2013-10-14 2020-09-09 2016-01-11 Many translated example sentences containing "apical surface" – German-English dictionary and search engine for German translations.
