Centrosome
Videos
The centrosome is a non-membrane bounded organelle in the animal cell that serves as the main microtubule organizing centre and a regulator of cell-cycle progression. The centrosome provides structure

Microtubule
Videos
Microtubules are biopolymers of tubulin that form part of the cytoskeleton to provide structure and shape to a eukaryotic cell. Microtubules can be as long as 50 micrometres, as wide as 23 to 27 nm an

…with the nuclear membrane during the prophase stage of the cell cycle. During mitosis, the nuclear membrane breaks down, and the centrosome-nucleated microtubules can interact with the chromosomes to build the mitotic spindle. The mother centriole, the older of the two in the centriole pair, also has a central…
Components of the eukaryotic cytoskeleton include: nuclei (blue), microtubules (green), and actin filaments (red).

Tubulin Infographic
Microtubules are one of the cytoskeletal filament systems in eukaryotic cells. The microtubule cytoskeleton is involved in the transport of material within cells, carried out by motor proteins that move on the surface of the microtubule.
