spindle fibers
The cables made of microtubules that extend from the poles of a cell to the centromeres during cell division are called spindle fibers or mitotic spindles. They help in the separation of chromosomes during mitosis or meiosis by attaching to the centromeres.
Kinetochore fibers are microtubules that attach to the kinetochore region of a chromosome during cell division, helping to pull the chromosome apart. Polar fibers, on the other hand, are microtubules that interact with each other and help push the poles of the cell apart during cell division, providing structural support.
During metaphase, the centromeres of chromosomes attach to spindle fibers (microtubules) that extend from opposite poles of the cell. This attachment helps properly align the chromosomes along the metaphase plate in the center of the cell before they are separated in anaphase.

Spindle Fibers
Spindle fibers are responsible for separating sister chromatids during mitosis by attaching to the centromere of each chromatid and pulling them toward opposite poles of the cell. This ensures that each daughter cell receives an identical set of chromosomes.
Interzonal spindle fibers are located between the two sets of chromosomes (sister chromatids) in the center of the cell during cell division. They help to separate the chromosomes by attaching to the kinetochores on each set of sister chromatids and pulling them towards opposite poles of the cell.
