Demonstrate familiarity with various components of the cytoskeleton, including monomeric units<\/h2>\r\nIf you were to remove all the organelles from a cell, would the plasma membrane and the cytoplasm be the only components left? No. Within the cytoplasm, there would still be ions and organic molecules, plus a network of protein fibers that help maintain the shape of the cell, secure some organelles in specific positions, allow cytoplasm and vesicles to move within the cell, and enable cells within multicellular organisms to move. Collectively, this network of protein fibers is known as the\u00a0cytoskeleton<\/strong>. There are three types of fibers within the cytoskeleton: microfilaments, intermediate filaments, and microtubules (Figure 1). In this outcome, we will examine each.\r\n\r\n[caption id=\"attachment_2020\" align=\"aligncenter\" width=\"1115\"]\"Microfilaments Figure 1. Microfilaments thicken the cortex around the inner edge of a cell; like rubber bands, they resist tension. Microtubules are found in the interior of the cell where they maintain cell shape by resisting compressive forces. Intermediate filaments are found throughout the cell and hold organelles in place.[\/caption]\r\n
