title: Cytoskeletal elements in neurons.
abstract: Neurotubules and neurofilaments are homologous with cytoplasmic microtubules and microfilaments which are seen with the electron microscope in most plant and animal cells. Their subunits are transported to the growth cone of the outgrowing axon, where the subunits are added to the distal ends of the neurotubules.
