Procephalothrix filiformis, confocal laserscanning (cLSM) micrographs of differently immunostained whole mounts of.

a: Anti-FMRF, z-coded stack. The major lateral medullary cords (mc), some minor lateral nerves (mln) as well as a ventral nerve (vn) are visible. pn: proboscis nerves. b: Anti-FMRF. The neurites (ne) of the intraepidermal plexus are arranged in a ladder-like way. c: Anti-FMRF. On the very tip of the head is a cluster of cells showing immunoreactivity against FMRF (arrow).
