Question

Quizplus · Accepted Answer

Intermediate filaments are tough, ropelike fibers composed of a variety of related proteins like keratin. Microfilaments are thin, flexible fibers composed of actin that provide mechanical support and help with cellular movement, while microtubules are hollow tubes composed of tubulin that play a role in cell division and intracellular transport. Macrofilaments are not a type of cytoskeletal element.
