if you take a look at most drawings of a cell in the cell organelles a major component is usually missing the cytoskeleton welcome to moomoomath and science and the cytoskeleton as the name implies it is the skeleton of the cell well kinda the cytoskeleton of a cell is a network of filaments running throughout the cell the cytoskeleton has several different jobs first it helps provide support much like your skeleton provides support for yourself it provides tracks or highways for the movements of vesicles and other objects in the cell it helps pull the chromosome apart during mitosis and even helps the cell move some single cell organisms have cilia made up of cytoskeleton filament the cytoskeleton consists of three types of fibers microfilaments intermediate filaments and microtubules microfilaments are fine thread like proteins fibers they are composed predominantly of a protein called actin these filaments create surface highways for the vesicles that need to be moved in the cell and may even hold organelles in place intermediate fibers are medium in length and they help maintain the shape of the cell for example a red blood cell has a unique donut shape the cytoskeleton filaments help produce this unique shape and finally microtubules are the largest filaments and also create tracts for proteins think of the microtubules as roads in the cell they also help pull the chromosomes apart during mitosis microtubules also help with the movement of the entire cell by creating flagella or cilia that helps propel certain cells if you'd like to know more about cell organelles this playlist will help and as always thanks for watching and moomoomath uploads a new math and science video every day please subscribe and share
