What do you mean by the dynamism of the cytoskeleton?

The cytoskeleton is a highly dynamic network of filamentous proteins that exists in three-dimensional space to link all regions and components of the cell. All cells, including bacteria, have a cytoskeleton in one form or another. This network is multifunctional, providing structural support for the cell, a scaffold for active transport mechanisms, and a system for generating and transducting mechanical force. The cytoskeleton is analogous to the railroad tracks connecting different parts of the city and the steel frame of a high-rise building. The former allows the delivery of passengers or goods to be guided through the city, while the latter ensures that the building does not collapse under its own weight and can maintain a dynamic internal environment.
