One primary function of the microtubules is to give the cell its shape and structure much like how skeletons in humans give the body shape and structure. Some microtubules are less than 200 nm long but in the long processes of nerve cells their lengths may be as great as 25 μm ie 25000 nm.
A centrosome is comprised of two centrioles as shown below thanks again to Kelvinsong.
Function of microtubules in animal cell. Also asked what is the function of microtubules in animal cell. Microtubules are fibrous hollow rods that function primarily to help support and shape the cell. They also function as routes along which organelles can move throughout the cytoplasm.
Microtubules are typically found in all eukaryotic cells and are a component of the cytoskeleton as well as cilia and flagella. One primary function of the microtubules is to give the cell its shape and structure much like how skeletons in humans give the body shape and structure. A cell has a history.
Its structure is inherited it grows divides and as in the embryo of higher animals the products of division differentiate on complex lines. During cell division microtubules are used to sort the chromosomes into the two daughter cells as is the function in animal cells through the formation of the mitotic spindle. In animal cells the major microtubule-organizing center is the centrosome which is located adjacent to the nucleus near the center of interphase nondividing cells Figure 1139.
During mitosis microtubules similarly extend outward from duplicated centrosomes to form the mitotic spindle which is responsible for the separation and distribution of chromosomes to daughter cells. These observations are consistent with increased efficiency of cell-to-cell spread of viral infection supporting the idea that microtubules function in the transport of vRNA to plasmodesmata 34.

Its primary role is to protect the cell from its surrounding. Also it controls the entry and exit of nutrients and other microscopic entities into the cell. Microtubules are hollow fibrous shafts whose main function is to help support and give shape to the cell.
They also serve a transportation function as they are the routes upon which organelles move through the cell. Microtubules are nucleated and organized by microtubule organizing centers MTOCs such as the centrosome found in the center of many animal cells or the basal bodies found in cilia and flagella or the spindle pole bodies found in most fungi.

Animal cells are the types of cells that make up most of the tissue cells in animals. Microtubules can grow as long as 50 micrometres and are highly dynamic. Microtubule length is quite variable.

Microtubules are typically found in all eukaryotic cells and are a component of the cytoskeleton as well as cilia and flagella. In animals quiescent cells and even cells in interphase usually have just one MTOC called a centrosome which serves as the central hub for all microtubules in the cell. A centrosome is comprised of two centrioles as shown below thanks again to Kelvinsong.
The two centrioles disengage from each other and replicate themselves during S phase and then separate to form opposite poles. In animal cells centrosomes are also called MTOCs. It is the site where microtubules are produced.
Centrosome has a pair of small organelles called centrioles each made up of a ring of nine groups of microtubules. During cell division centrosome divides and centrioles replicates resulting in two centrosomes with its own centrioles. Microtubules are filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells.
Microtubules are involved in nucleic and cell division organization of intracellular structure and intracellular transport as well as ciliary and flagellar motility.
