Fig. 7. Confocal images of whole mounts of myoinhibitory peptide (MIP)-like immunoreactivity in Bombyx mori. (A) Left hemisphere of the brain of a third-instar larva, showing an immunoreactive median neurosecretory cell (arrowhead) and its ipsilateral projection (arrow). (B) Retrocerebral complex of a third-instar larva, showing MIP-immunoreactive (MIP-IR) processes in the corpus cardiacum (CC) but not in the corpus allatum (CA). (C) Epiproctodeal gland of a fourth-instar larva showing an extensive MIP-IR neurohemal system. Scale bars, 50 µm.
