Terminal web
 | This article may be too technical for most readers to understand. (September 2015) |
The terminal web is a filamentous structure found at the apical surface of epithelial cells that possess
myosin II and tropomyosin helps to explain the contractile ability of the terminal web. When contracted, the terminal web causes a decrease in diameter of the apex of the cell, causing the microvilli, which are anchored into the terminal web through their stiff actin fibers, to spread apart. This spreading apart of the microvilli aids cells in absorption.[1][2][3][4]
