WebThe microtubule cytoskeleton provides a scaffold for the axonal plasma membrane and supports axonal transport. Disruption of microtubules in axons can lead to the collapse of the axonal cytoskeleton and impaired transport of organelles and vesicles. Furthermore, microtubules also contribute to the growth and guidance of axons during development. WebActin and spectrin are important constituents of axonal cytoskeleton. Periodic actin-spectrin structures are found in dendrites, initial segment of axon, and main axon.
