intermediate filaments
Intermediate filaments are part of the cell’s internal skeleton, providing structural support and helping maintain its shape. Think of them as sturdy cables woven throughout the cell, anchoring organelles and resisting mechanical stress. They are more durable than other cytoskeletal elements like actin filaments and microtubules, which allows cells to withstand stretching and deformation. Different types of intermediate filaments are specialized for various tissues, such as keratin in skin, vimentin in connective tissue, and neurofilaments in nerve cells. Overall, they play a crucial role in maintaining cell integrity, organization, and resilience under physical stress.
