Kinesin and motor neurons Kinesin is a MAP, a motor protein affiliated with microtubules that aid in intracellular transport of vesicles. Intermediate fiaments and intercellular junctions Intermediate filaments include various filamentous proteins characteristic of particular tissues - including structural support in epithelial, muscle, C.T. and nerve cells. Cytokeratin is an I.M. filament that contributes to Desmosomes. Cadherin and integrin These are integral plasma membrane proteins that play roles in cellular adhesions. Integrins are found at the basal surface of epithelial cells as contributors to hemidesmosomes.
Examples are centrioles and basal bodies.
CSF and ependyma Ependyma refers to the epithelial lining tissue of the central nervous system. It is the holdover of the original ectodermal lining tissue of the neural tube. During brain development, specific portions of the ependyma along with underlying loose CT, invaginate to form choroid plexus. The CSF is released into the local ventricular spaces, bathes them, and flows out to the spaces surrounding the brain and cord. These are substances known to interfere with cytoskeletal structures.
