What is the terminal web layer inside the plasma membrane?

The terminal web layer is a specialized network of cytoskeletal filaments located just beneath the plasma membrane of epithelial cells. It is primarily composed of actin filaments, along with associated proteins, and plays a crucial role in maintaining cell shape and providing structural support. This layer also anchors membrane proteins and contributes to the formation of specialized structures like microvilli, enhancing the cell's surface area for absorption or secretion. Overall, the terminal web is essential for cellular integrity and function.
