Cytoskeleton Notes for NEET | Microtubules, Microfilaments & Cell Structure Explained

  Cytoskeleton – Easy Notes for NEET  Cytoskeleton structure showing microtubules, microfilaments, and intermediate filaments inside a cell. - Dr.Sanjaykumar Pawar  Definition Cytoskeleton is a network of protein fibres present in the cytoplasm of a cell. It forms the internal framework or "skeleton" of the cell. It is made up of filamentous (thread-like) protein structures. Components of Cytoskeleton The cytoskeleton consists of three main types of fibres: Microtubules Long, hollow, tube-like structures. Made of the protein tubulin . Help in cell division and movement of cell organelles. Microfilaments Thin, solid fibres. Made of the protein actin . Help in cell movement and change in cell shape. Intermediate Filaments Fibres of intermediate thickness. Provide strength and stability to the cell. Help the cell resist mechanical stress. Location Present throughout the cytoplasm of eukaryotic cells. Forms a supporting network inside th...
