Called also mitotic spindle.mitotic spindle spindle (def. 2).muscle spindle a mechanoreceptor found between the skeletal muscle fibers; the muscle spindles are arranged in parallel with muscle fibers, and respond to passive stretch of the muscle but cease to discharge if the muscle contracts isotonically, thus signaling muscle length.

2014) - "Mitotic spindle: kinetochore fibers hold on tight to interpolar bundles" 2008-01-02 · Spindle fibers are derived from the kinetichore. The are made up of microtubules, associated proteins, asters, centrosomes, etc. So mitotic spindles are made up of more than just microtubules. At the beginning of nuclear division, two wheel-shaped protein structures called centrioles position themselves at opposite ends of the cell forming cell poles. Long protein fibers called microtubules extend from the centrioles in all possible directions, forming what is called a spindle.

2017-07-19 · Kinetochore fibers are the main generators of forces that move the chromosomes during mitosis. When sister kinetochores become attached to microtubule fibers extending from the opposite spindle poles, which is known as biorientation, these fibers hold the chromosomes near the spindle equator (Maiato et al. 2017).

mitotic spindle synonyms, mitotic spindle pronunciation, mitotic spindle translation, English dictionary definition of mitotic spindle. n. One of a network of achromatic filaments that extend inward from the poles of a dividing cell, forming a spindle-shaped figure. phase spindles recovered rapidly as the detached pole moved back towards the chromosomes, reestablishing spindle fibers as the ARB closed; this happened when the ARB cut a few fibers or across the entire half spindle. We never detected elongation of the cut kinetochore fibers. Spindle microtubules are assembled from opposite spindle poles and a fraction of them are organized to form thick bundles of spindle fibers (k‐fibers) during prophase till prometaphase. At prometaphase, the k‐fibers are yet to establish attachment with the kinetochores of both sister chromatids of the individual chromosomes (biorientation).

The mitotic spindle performs the task of physically dividing the genetic material between the newly formed daughter cells. To achieve this, bundles of microtubules and associated proteins orchestrate forces that spatially organize and then separate the chromosomes. In the classic view of the spindle, the kinetochore microtubules (k-fibers) are tensed and, thus, straight, whereas interpolar
