The role of spindle fibers during cell divsion is that it forms a bridge between the ends of the cell.
They pull the sister chromatids apart.
Centrioles play an essential role in mitosis. Centrioles replicate during interphase, and in prophase, they move to the poles of the cell and spindle fibers begin to form from these poles. Those are the primary functions of a centriole. It is also important to note that these organelles are only present in animal cells.
The centrioles are similar to a railing at the two ends of a cell. The spindle fibers attach to the chromosomes (matching pairs) which are lined up in the middle of the cell. This spot is called the equator. The spindle fibers are also attached to the centrioles. The fibers begin to pull the chromosomes apart while holding fast to the centrioles. See the animation link below:
Microtubules are structured around a cell region called the centrosome

It provides a "scaffolding" for the attachment and movements of the chromosomes during the later mitotic stages.
Spindle-shaped muscle fibers are skeletal muscles that produce external mobility to the body.

During Mitosis, during metaphase, the centrioles grow spindle fibers which attach to the chromosomes located currently on the centrosome. They then pull one half of the chromosome to their side of the cell, this process is called anaphase. They then disappear.

as the furrow gets very narrow, the spindle fibers then are pressed toghther into a tight bundle causing a stembody.
