Which of the following describes intermediate filaments?

Intermediate filaments are a type of cytoskeletal component that provide structural support and mechanical strength to cells. They are characterized by their configuration, which involves coiling into thicker cables composed of various proteins, such as keratins, vimentin, and lamins. This coiled structure allows them to withstand tension and contribute to the cell's overall stability.

The other options describe different types of cytoskeletal elements. For instance, thin strands suggest microfilaments, which are involved in movement and shape changes in the cell. Hollow tubes pertain to microtubules, which play roles in cell division, intracellular transport, and maintaining the cell's shape. Rigid structural support is more typical of components like the cell wall in plants or even the extracellular matrix, rather than describing the dynamic nature of intermediate filaments. The unique properties of intermediate filaments, particularly their coiled design, distinguish them as crucial for maintaining the integrity and resilience of the cell under various mechanical stresses.
