MICROANATOMY

Detailed explanation-1: -The cytoskeleton is a network of different protein fibers that provides many functions: it maintains or changes the shape of the cell; it secures some organelles in specific positions; it enables movement of cytoplasm and vesicles within the cell; and it enables the cell to move in response to stimuli.

Detailed explanation-2: -Microtubules are the thickest of the cytoskeletal fibers. These are hollow tubes that can dissolve and reform quickly. Microtubules guide organelle movement and are the structures that pull chromosomes to their poles during cell division. They are also the structural components of flagella and cilia.

Detailed explanation-3: -The cytoskeleton of a cell is made up of microtubules, actin filaments, and intermediate filaments. These structures give the cell its shape and help organize the cell’s parts. In addition, they provide a basis for movement and cell division.

Detailed explanation-4: -In addition to its role as the cytoskeleton, filamentous actin (F-actin) serves as a track for movement of intracellular organelles such as mitochondria and secretory granules [1].
