Fig. 3. Expression of the crustacean cardioactive peptide (CCAP) transcript in the
subesophageal ganglion (SEG) of Manduca sexta. (A) Ventral view of an
air-filled third-instar SEG showing a pair of posteriolaterally located cells
(concave arrows) and a pair of smaller midline cells (arrows). (B) Ventral
view of an air-filled fourth-instar larval SEG showing the previously
discussed four cells (described in A) and an anteriolateral pair (convex
arrows; left cell out of focus). (C) Ventral view of an SEG from a day 0
fourth-instar larva showing the posteriolaterally located cells (concave
arrows), the anteriolateral cells (convex arrows) and a single anterior cell
to the left of the midline (arrowhead). (D) Posterior view of an adult SEG
showing only one pair of CCAP-expressing cells (arrows). Inset: diagram of the
adult brain showing the area from where D was obtained (box; X indicates
positions of cells). Scale bars, 50 µm.
