  2. Microfilament - Wikipedia

    en.wikipedia.org/wiki/Microfilament

    Microfilaments, also called actin filaments, are protein filaments in the cytoplasm of eukaryotic cells that form part of the cytoskeleton. They are primarily composed of polymers of actin , but are modified by and interact with numerous other proteins in the cell.

  3. Cytoskeleton - Wikipedia

    en.wikipedia.org/wiki/Cytoskeleton

    Like tubulin, FtsZ forms filaments in the presence of guanosine triphosphate (GTP), but these filaments do not group into tubules. During cell division , FtsZ is the first protein to move to the division site, and is essential for recruiting other proteins that synthesize the new cell wall between the dividing cells.

  4. Protein filament - Wikipedia

    en.wikipedia.org/wiki/Protein_filament

    Developing wood cells in poplar showing microfilaments (in green) and cell nuclei (in red). In biology, a protein filament is a long chain of protein monomers, such as those found in hair, muscle, or in flagella. [1]

  5. Actin - Wikipedia

    en.wikipedia.org/wiki/Actin

    Actin is a family of globular multi-functional proteins that form microfilaments in the cytoskeleton, and the thin filaments in muscle fibrils.It is found in essentially all eukaryotic cells, where it may be present at a concentration of over 100 μM; its mass is roughly 42 kDa, with a diameter of 4 to 7 nm.

  6. Microtubule - Wikipedia

    en.wikipedia.org/wiki/Microtubule

    Another area where microtubules are essential is the development of the nervous system in higher vertebrates, where tubulin's dynamics and those of the associated proteins (such as the microtubule-associated proteins) are finely controlled during the development of the nervous system.

  7. Lamellipodium - Wikipedia

    en.wikipedia.org/wiki/Lamellipodium

    Lamellipodia are thin-like projections on the leading edge of a cell (Image A). It is a feature of motile cells such as endothelial cells, neurons, and immune cells. The lamellipodia on the leading edge of the cell (green arrows) contain ATP- bound actin and the lamella on the "spike" end of the cell contain ADP-bound actin (red arrow).

  8. Microplastics Are in All of Us. Just How Bad Is That, Really?

    Woodruff, who has studied the effect of some chemicals found in plastics on human health, reproduction, and development for two decades, first started looking into microplastics in 2021.

  9. Microvillus - Wikipedia

    en.wikipedia.org/wiki/Microvillus

    Microvilli are observed on the plasma surface of eggs, aiding in the anchoring of sperm cells that have penetrated the extracellular coat of egg cells. Clustering of elongated microtubules around a sperm allows for it to be drawn closer and held firmly so fusion can occur. They are large objects that increase surface area for absorption.
