    Attachment of microtubules to chromosomes is mediated by kinetochores, which actively monitor spindle formation and prevent premature anaphaseonset. Microtubule polymerization and depolymerization dynamic drive chromosome congression. Depolymerization of microtubules generates tension at kinetochores; bipolar attachment of sister kinetochores to microtubules emanating from opposite cell poles couples opposing tension forces, aligning chromosomes at the cell equator and poising them for

  • Spindle neuron Wikipedia

    Spindle neurons, also called von Economo neurons (VENs), are a specific class of neurons that are characterized by a large spindle-shaped soma (or body), gradually tapering into a single apical axon (the ramification that transmits signals) in one direction, with only a single dendrite (the ramification that receives signals) facing opposite. Other neurons tend to have many dendrites, and the

    Structure. Muscle spindles are found within the belly of muscles, between extrafusal muscle fibers. The specialised fibers that constitute the muscle spindle are known as intrafusal fibers (as they are present within the spindle), to distinguish themselves from the fibres of the muscle itself which are called extrafusal fibers. Muscle spindles have a capsule of connective tissue, and run

    2019-11-11· Spindle fibers are part of a spindle apparatus that moves chromosomes during mitosis and meiosis to ensure even chromosome distribution between daughter cells. The spindle apparatus of a cell is comprised of spindle fibers, motor proteins, chromosomes, and, in some animal cells, microtubule arrays called asters.

  • What Function Do Spindles Perform During Mitosis? Sciencing

    Spindle fibers are protein structures that form early in mitosis, or cell division. They consist of microtubules that originate from the centrioles, two wheel-shaped bodies located in the centromere area of the cell. The centromere is also known as the microtubule organizing center. The spindle

    Microtubule structure Functions of Spindle Fibers Shrinkage and Growth. The main feature of microtubules, and therefore of spindle fibers, is that the proteins which control them can extend or contract the microtubule by adding or removing tubulin dimers.At first the MTOCs must add many of these dimers to the microtubule, to extend it across the cell.
