Microfilaments and Their Functions in Cellular Biology

Microfilaments are responsible for forming a meshwork called nuclear lamina just beneath the inner nuclear membrane.

Intermediate filaments are involved in cell migration and cell division.

Microfilaments are responsible for cell junctions.

Cytoskeletal organization remains constant during cell division.

Intermediate filaments are found only in the plasma membrane.

Microfilaments are involved in muscle contraction.

Desmin intermediate filaments are found in epidermal cells.

Microtubules are involved in cell division.

Keratin intermediate filaments are specific to muscle cells.

The cytoskeleton provides mechanical resistance to deformation and helps maintain cell shape.

Microtubules provide internal support to the cell and are involved in cell migration.

Microfilaments are involved in the uptake of extracellular material (endocytosis).

Vimentin intermediate filaments are found in neurons.

The cytoskeleton is only involved in cell migration, but not in cell division.

Intermediate filaments are not involved in organizing the contents of the cell in space.

The diameter of microtubules is approximately 15 nm.

The cytoskeleton is a static structure that does not change shape.

The cytoskeleton is only found in the cytoplasm of eukaryotic cells.
