Where are centrosomes (microtubule-organizing-centers) located in an animal cell?

The centrosome, cytocenter, or cell center is unique to animal cells. It is close to the nucleus and is considered an organizing center for microtubules.

Explanation:

The centrosome is a nonmembranous organelle, present in all dividing animal cells. It is located near the nucleus, often surrounded by the dictyosomes of the Golgi apparatus. The structure consists of an interior zone where the diplosome appears, formed by two centrioles arranged perpendicular to each other. The microtubules emanating from the centrosome end up in the pericentriolar material, not the centrioles, and it is the pericentriolar material that initiates the assembly of the microtubules. Therefore, the main function of the centrosome is to nuclear and anchor the microtubules.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
