Final answer:
Microvilli contain cytoskeletal elements known as microfilaments, which are essential for maintaining their structure and function in increasing the cell's surface area for absorption.
Step-by-step explanation:
Yes, microvilli do contain cytoskeleton elements, specifically microfilaments. These are the thinnest of the cytoskeletal fibers and they play a critical role in moving cellular components and maintaining the structure of the microvilli, which are tiny, finger-like projections on the surface of epithelial cells, aimed at increasing their surface area for absorption. Each microvillus contains a core bundle of actin filaments, which are cross-linked by binding proteins that give them stiffness and the capacity to recover their shape, making the cytoskeleton dynamic and able to reassemble and rearrange to adapt to the cell's needs.
