the microscopic, fingerlike projections of cell membranes of small intestinal cells; they increase surface area for absorption
thin, fingerlike projections from the apical surface of specialized epithelial cells that increase the absorptive area by up to 25-fold.
(singular: microvillus) • The projections of epithelial cells, such as the cells lining the small intestine, that increase their surface area.
microscopic projections of the plasma membrane of individual epithelial cells, to increase surface area in areas specialized for absorption or secretion (e.g., GI tract). Do not confuse these with villi (multicellular), or with cilia.
Thin cylindrincal projections of the plasma membrane that are particularly abundant on epithelial cells in the small intestine.
(mi'-kro-VIHL-i) Microscopic extensions of the cell membrane filled with cytoplasm that serve to increase the absorptive surface area of the cell.
Microvilli are cytoplasmic finger-like protrusions from a cell surface. They are present on the apical surface of most epithelia. In the intestinal absorptive cell they are known as the "striated border" and in the kidney tubule cell they are known as the "brush border".
Small, fingerlike extensions of the exposed cell membrane of an epithelial cell.
minute projections on the surface of cells that greatly increase their surface area, e.g., on the cells of villi of the small intestine
Hair-like projections on the surface of the epithelial cells of the villi in the small intestine; increase the surface area of the intestine to improve absorption of digested nutrients. PICTURE
Thin fingerlike protrusions from the surface of a cell, often used to increase absorptive capacity or to trap food particles. The "collar" of choanoflagellates is actually composed of closely spaced microvilli.
Projections on the apical surface of some epithelial cells which increase the surface area for absorpiton
Microscopic projections on luminal surface of epithelial cells that increase the surface area for exchange.
