Neurotubules

• The cytoskeleton of dendrites is formed of longitudinal tubules forming the axis of dendritic shafts. The diameter of the tubules is uniform with relative separations that form the dendrite diameter. At bifurcations, tubules do not branch but assemble their number into respetive branches. The tubules shift around mitochondria and endoplasmic reticulum. They pass, also, through ER showing separation of the tubules from the ER as though some nonstained material surrounds each tubule.
