Sliding filament theory is a model used to explain the mechanism by which muscles contract. The contraction of skeletal muscle, which is what makes movement possible, occurs in three ways.
The cytoskeleton is responsible for cell shape, motility (movement) of the cell as a whole, and motility of organelles within a cell.There are three types of filaments in the cytoplasm of most vertebrate cells: microfilaments, microtubules, and intermediate filaments.he microfilament system is a network of filaments 6 nanometers (nm) in diameter that are important for anchoring plasma membrane proteins, for producing cell movement, and for cell division. The base filament is composed of a protein called actin that is 42 kilodaltons (kd) in weight.
