Cytoskeleton explained
WebCytoskeleton definition, a shifting lattice arrangement of structural and contractile components distributed throughout the cell cytoplasm, composed of microtubules, … The cytoskeleton is a complex, dynamic network of interlinking protein filaments present in the cytoplasm of all cells, including those of bacteria and archaea. In eukaryotes, it extends from the cell nucleus to the cell membrane and is composed of similar proteins in the various organisms. It is composed of three main components, microfilaments, intermediate filaments and microtubules, an…

WebAug 17, 2024 · As its name suggests, the cytoskeleton is like a cellular “skeleton.” It helps the cell maintain its shape and also helps to hold cell structures such as organelles in place within the cytoplasm. Figure \(\PageIndex{2}\): Cytoskeleton. The cytoskeleton gives the cell an internal structure, like the frame of a house. WebSection summary. 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.
