Mitotic spindle.
| spindle (spĭn'dl) Pronunciation Key
A network of protein fibers that forms in the cytoplasm of a cell during cell division. The spindle grows forth from the centrosomes and attaches to the chromosomes after the latter have been duplicated, and the nuclear membrane dissolves. Once attached, the spindle fibers contract, pulling the duplicate chromosomes apart to opposite poles of the dividing cell. See more at meiosis, mitosis. |
