Centrosome (centrum=center, soma=body)
it lies near the nucleus
helps maintain the shape of the cell & acts as tracks along which organelles can move

The array is called the mitotic spindle. It is made up of microtubules that radiate from the centrosomes and are crucial for the separation of chromosomes during cell division.
A household item that can represent a centrosome is a coffee cup with a stirrer. The coffee cup serves as the central structure, analogous to the centrosome, while the stirrer represents the microtubules that radiate out from the centrosome, helping to organize and support the cellular structure. Just as a centrosome organizes the cell's microtubules, the stirrer helps mix and distribute the contents of the cup.
Yes, spindle fibers and microtubules are essentially the same in that spindle fibers are composed of microtubules. Microtubules are a component of the cytoskeleton, made of tubulin protein subunits, and they play various roles in cellular structure and transport. During cell division, specifically in mitosis and meiosis, microtubules organize into spindle fibers that help separate chromosomes. Thus, while all spindle fibers are microtubules, not all microtubules function as spindle fibers.
Asters are formed during the prophase of mitosis in animal cells. They are structures made up of microtubules that radiate from the centrosomes, which help in the organization and separation of chromosomes during cell division. The formation of asters is crucial for the proper alignment and segregation of chromosomes to ensure accurate cell division.
Microtubules
Microtubules radiate from the microtubule-organizing center (MTOC) located near the center of the cell. They play a key role in various cellular processes, including cell division and intracellular transport.
The array is called the mitotic spindle. It is made up of microtubules that radiate from the centrosomes and are crucial for the separation of chromosomes during cell division.
The starburst pattern formed by microtubules around the centriole is called the astral array. These microtubules radiate outwards from the centriole like the rays of a star, providing structural support and helping to position the centriole during cell division. Additionally, the astral microtubules are involved in organizing the mitotic spindle and ensuring accurate chromosome segregation.

Cilia and flagella are made up of microtubules, specifically arranged in a 9+2 pattern. They consist of nine doublets of microtubules surrounding a central pair of microtubules. The movement of cilia and flagella is generated by the sliding of these microtubules past each other.
