The epithelial cells lining the central canal are conical, their bases facing the canal, their pointed extremity being drawn out into a fine filament intimately inter- woven with the network of neuroglia fibrils. In the embryo and young state (Figs. 130a and 130b), the free base of the epithelial cells has a bundle of cilia, but in the adult they are lost amongst the epithelial cells.
