Microtubules (MTs) are essential for neuronal morphogenesis in the developing brain. The MT cytoskeleton provides physical support to shape the fine structure of neuronal processes. MT-based motors play important roles in nucleokinesis, process formation and retraction.unction of microtubules in the spatial regulation of polarization signals. Axonogenesis, the extension of a single immature process and its differentiation into an axon, is the initial morphological event that defines neuronal polarization.
