(A) A 3-D lateral view of an early bipinnaria showing immunoreactive cell bodies and axonal-like tracts following the ciliated bands. The anterior ganglion (ag) has formed and connects the preoral (procb) and postoral (pocb) ciliated bands, adocb. adoral ciliated band; o. esophagus; s, stomach; i, intestine. Bar, 95 (B) Ventral view of an early bipinnaria at the same stage as in panel A. The ciliated bands are developing, but the anterior extension has not yet formed. Black arrowheads, preoral ciliated band; white arrowheads, postoral ciliated band; white arrow, adoral ciliated band; in. mouth; a. anus. Bar, 100 /u,m. 5-HT-like immunoreactivity; the apical ends of these cells extended to the edge of the ciliated epithelium. These cells were pyramidal and connected basally \-ui a thick immu- nopositive tract (Fig. 6A). Compared with the other ciliated bands, the adoral ciliated band had the highest concentration. Figure 4. Scanning electron micrographs of a hipinnaria showing fully developed ciliated bands (arrowheads and arrows): (A) Ventral view of a bipinnaria with a flexed oral hood and mouth (m) open showing the position of the adoral ciliated band (adcb). (B) Lateral view of a bipinnaria showing the anterior extension of the oral hood, top right-hand side. Double-ended arrow indicates the anterior region where the anterior gan- glion links the preoral and postoral ciliated bands. Arrowheads, preoral ciliated band; arrows, postoral ciliated band: Bar, 200 /urn. of immunoreactive cells and processes, forming the adoral nerve plexus (ADNP). The ADNP innervated the epithe- lium of the adoral ciliated band. Confocal optical sectioning revealed that the apical region of these cells protruded to the exterior of the ciliated band epithelium.
