Fibers with diameters in a middle range

Provide mechanical stability and resistance to shear stress

**************************** determine the positions of membranous organelles and direct intracellular transport

Hollow, cylindrical structure of polymerized α- and β-tubulin dimers with polarized ends

Helical structure of strands of polymerized actin subunits with polarized ends

Made from strands of anti-parallel tetramers, which are composed of a variety of proteins (e.g., vimentin, desmin, keratin, neurofilament, glial fibrillary acid proteins) depending on the specific cell

Motor proteins (*******. ********) bind to the microtubule and use ATP to transport vesicles around the cell

Found in mitotic spindles, cilia, flagella, and axons

Type of anchoring junction that links the intermediate filaments in two adjoining cells

Main type of occluding junction in vertebrates; it seals adjacent epithelial cells together, preventing the passage of most dissolved molecules from one side of the epithelial sheet to the other.

Anchoring junction that connects actin filaments in one cell to those in the next cell

They directly connect the cytoplasm of two cells, which allows various molecules, ions and electrical impulses to directly pass through a regulated gate between cells.

Cellular Junction in plant cells that allows small molecules in the cytoplasm to be shared between the cells to aide in communication.

Cellular Junction in animal cells that allows for cellular communication through flow of cytoplasm between cells.

Place a seal around the cells to prevent leakage.

Which is NOT a role of the cytoskeleton?
