MICROANATOMY

Detailed explanation-1: -So the centrioles are critical to allow the mitotic spindle to form, which is critical to allow cytokinesis. As to be distinguished from the centrosome, which is an area of the cell next to the nucleus where the centrioles normally live when the cell is not undergoing mitosis.

Detailed explanation-2: -Long protein fibers called microtubules extend from the centrioles in all possible directions, forming what is called a spindle.

Detailed explanation-3: -Before the first division of the embryo, the centrioles introduced by the sperm duplicate and take part in organizing the first mitotic division. New centrioles assemble during S phase of the cell cycle in dividing cells.
