Figure 14. S-I (green) and SCP-I (red) neurons in abdominal ganglion at left of gut. The S-I neurons in the ganglia did not appear to project to the gut, which is only innervated by the bilateral pair of S-I axons from the CNS; the SCP-I axon running across the gut (arrow) could be traced to the ganglion as shown in B, the same view showing only the SCP-I and with the focus on the gut surface.
