In cell biology, the spindle apparatus is the cytoskeletal structure of eukaryotic cells that forms during cell division to separate sister chromatids between daughter cells. It is referred to as the mitotic spindle during mitosis , a process that produces genetically identical daughter cells, or the meiotic spindle during meiosis , a process ...
The spindle apparatus rotates in the round cell and after several minutes the spindle position is stabilised preferentially along the interphase cell long axis. The cell then divides along the spindle apparatus orientation. The first insights into how cells could remember their long axis came from studies on the Drosophila epithelium. The study ...
TCJ provide mechanical and geometrical clues for the spindle apparatus to ensure that cell divide along its long axis. [10] Several factors could regulate cell shape and therefore orientation of cell division. Among these factors is the anisotropic mechanical stress.
It forms perpendicular to the axis of the spindle apparatus [2] towards the end of telophase, in which sister chromatids are identically separated at the opposite sides of the spindle forming nuclei (Figure 1).
This spindle apparatus consists of microtubules, microfilaments and a complex network of various proteins. During metaphase, the chromosomes line up using the spindle apparatus in the middle of the cell along the equatorial plate. The chromosomes move to opposite poles during anaphase and remain attached to the spindle fibers by their centromeres.

Pentagon officials are holding informal discussions about how the Department of Defense would respond if Donald Trump issues orders to deploy active-duty troops domestically and fire large swaths ...
In the vertical milling machine the spindle axis is vertically oriented. Milling cutters are held in the spindle and rotate on its axis. The spindle can generally be lowered (or the table can be raised, giving the same relative effect of bringing the cutter closer or deeper into the work), allowing plunge cuts and drilling.
