The cytoskeleton is a network of different protein fibers that provides many functions: it maintains or changes the shape of the cell; it secures some organelles in specific positions; it enables movement of cytoplasm and vesicles within the cell; and it enables the cell to move in response to stimuli.

Microfilaments also provide some rigidity and shape to the cell. They can depolymerize (disassemble) and reform quickly, thus enabling a cell to change its shape and move. White blood cells (your body’s infection-fighting cells) make good use of this ability. They can move to the site of an infection and phagocytize the pathogen.
4 kwi 2017 · The cytoskeleton is a network of filaments and tubules that extends throughout a cell, through the cytoplasm, which is all of the material within a cell except for the nucleus. It is found in all cells, though the proteins that it is made of vary between organisms.
1 sty 2010 · The cytoskeleton carries out three broad functions: it spatially organizes the contents of the cell; it connects the cell physically and biochemically to the external environment; and it generates coordinated forces that enable the cell to move and change shape.
15 wrz 2009 · Below, we will provide an overview of the contribution of cell shape changes to cell migration and tissue morphogenesis in development and of the mechanical processes by which these cell shape changes are achieved and coordinated amongst multiple cells.
The cytoskeletal “highways” help provide structure and connection within the cell and between cells. The cytoskeleton influences the shape of the cell and aids in the relay of signals from one part of the cell to another. The cytoskeleton helps cells grow, move, retract, and even die.
21 sie 2019 · The cytoskeleton is a network of fibers forming the "infrastructure" of eukaryotic cells, prokaryotic cells, and archaeans. In eukaryotic cells, these fibers consist of a complex mesh of protein filaments and motor proteins that aid in cell movement and stabilize the cell.
