Examples of cytoskeleton in the following topics:

  • Microfilaments

    • Microfilaments, which are the thinnest part of the cytoskeleton, are used to give shape to the cell and support all of its internal parts.
    • This network of protein fibers is known as the cytoskeleton.
    • There are three types of fibers within the cytoskeleton: microfilaments, intermediate filaments, and microtubules.
    • Of the three types of protein fibers in the cytoskeleton, microfilaments are the narrowest.
  • Intermediate Filaments and Microtubules

    • Microtubules are part of the cell's cytoskeleton, helping the cell resist compression, move vesicles, and separate chromosomes at mitosis.
    • The cytoskeleton is the framework of the cell which forms the structural supporting component.
    • Microtubules are the largest element of the cytoskeleton.
    • With a diameter of about 25 nm, microtubules are the widest components of the cytoskeleton.
    • Describe the roles of microtubules as part of the cell's cytoskeleton
  • Adherens Junctions

    • Adherens junctions provide strong mechanical attachments between adjacent cells through the linkage of cytoplasmic face with cytoskeleton.
    • The actin microfilaments of the cytoskeleton (the internal skeleton of the cell). 
  • Injuring the Plasma Membrane

    • It serves as the attachment surface for several extracellular structures, including the cell wall, glycocalyx, and intracellular cytoskeleton.
    • The plasma membrane also plays a role in anchoring the cytoskeleton to provide shape to the cell and in attaching to the extracellular matrix and other cells to help group cells together to form tissues .
  • Characteristics of Eukaryotic DNA

    • Mitosis, a process of nuclear division wherein replicated chromosomes are divided and separated using elements of the cytoskeleton, is universally present in eukaryotes.
    • The cytoskeleton contains structural and motility components called actin microfilaments and microtubules.
  • Interphase

    • Some cell organelles are duplicated, and the cytoskeleton is dismantled to provide resources for the mitotic phase.
  • Microscopic Anatomy

    • Desmosomes, which bind adhesion proteins to the cytoskeleton within cells, thus connecting the cells.
  • Components of Plasma Membranes

    • The plasma membrane also plays a role in anchoring the cytoskeleton to provide shape to the cell, and in attaching to the extracellular matrix and other cells to help group cells together to form tissues.
  • Cell Migration in Multicellular Organisms

    • It generally involves drastic changes in cell shape which are driven by the cytoskeleton, for instance a series of contractions and expansions due to cytoplasmic displacement.
  • MreB and Determinants of Cell Morphology

    • MreB is a cytoskeleton element that assembles into filamentous structures within the bacterial cytoplasm.
