Surface view of a sub-tentacular comb row in living animal, showing four comb plates whose cilia are laid down flat on the surface, and giant axon chain (g). Scale bar: 100 jim. Figure 3. One () fim section cut transversely but at a slight angle through a comb plate showing massed cilia (dark mass, upper right) arising from polster cells, and giant axons (g). Gametes are seen in the underlying endodermal canal. Scale bar: 50 /jm. some overlap. In typical sections, one or two axon profile

Surface view of a sub-tentacular comb row in living animal, showing four comb plates whose cilia are laid down flat on the surface, and giant axon chain (g). Scale bar: 100 jim. Figure 3. One () fim section cut transversely but at a slight angle through a comb plate showing massed cilia (dark mass, upper right) arising from polster cells, and giant axons (g). Gametes are seen in the underlying endodermal canal. Scale bar: 50 /jm. some overlap. In typical sections, one or two axon profiles, but not more, are seen, showing that the neurites must be quite short, probably less than 400 ^m. In their thicker regions, they show diameters of approximately Mm (X = , SD = , n = 10), but they taper towards the ends. Allowing for shrinkage during fixation and embedding, the axons are probably at least 12 /urn in the living animal, which is also suggested by measurements.
