WebMicrovilli are tiny fingerlike structures that project from the exposed side of the plasma membrane and help to increase the surface area of the membrane without taking up too much space. The microvilli are useful when it comes to absorption of necessary nutrients and assist in the passage of specific materials into the plasma membrane. WebThe microvilli are shorter and narrower than cilia. (Microvilli is the plural of microvillus.) They contain bundles of parallel actin filaments held together into a bundle by cross …

This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer WebMicrovilli are cell surface modifications which increase surface area of a cell without significantly increasing the size of the cell. Microvilli are often seen in organs where the epithelium plays a primary role in the absorption of molecules. Microvilli are supported by an actin microfilament network.

WebTonofibrils are cytoplasmic protein structures in epithelial tissues that converge at desmosomes and hemidesmosomes. [1] They consist of fine fibrils in epithelial cells that are anchored to the cytoskeleton.
