WebSpindles are microtubule fibers that arrange and move chromosomes. It is necessary to equally divide the chromosomes in a parental cell into two daughter cells during mitosis. … WebThe mitotic spindle is a structure that forms during cell division and separates duplicated chromosomes. In eukaryotic cells, the mitotic apparatus is composed of two centrosomes and spindle microtubules ( Figure 43.9 ). The centrosome is 1–2 μm in diameter.

WebDuring prophase, the nucleus disappears, spindle fibers form, and DNA condenses into chromosomes ( sister chromatids ). During metaphase, the sister chromatids align along the equator of the cell by attaching their centromeres to the spindle fibers. WebThe spindle is a stretch receptor with its own motor supply consisting of several intrafusal muscle fibres. The sensory endings of a primary (group Ia) afferent and a secondary (group II) afferent coil around the non-contractile central portions of the intrafusal fibres. shark skin bathing suit
