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.
Microfilaments, or actin filaments, are the thinnest filaments of the cytoskeleton and are found in the cytoplasm of eukaryotic cells. The polymers of these linear filaments are flexible but still strong, resisting crushing and buckling while providing support to the cell. Microfilaments are very versatile cell components that serve a role in cytokinesis, movement, and changes in cell shape.
