Teloblasts were injected unilaterally with FDA and the embryos were fixed∼100 hours later. Only well-labeled preparations with the normal distribution of cell bodies were scored. Numbers in parentheses represent the total number of midbody ganglia that were scored, some of which were in the same embryo. Projections into the DP nerve were not apparent in the preparations examined. Abbreviations are given in Fig. 2.
