MORPHOLOGY OF NEURONS IN THE STORAGE PART OF THE CORPUS CARDIACUM OF LOCUSTA-MIGRATORIA - NO EVIDENCE FOR THEIR INVOLVEMENT IN THE REGULATION OF ADIPOKINETIC CELL-ACTIVITY

The storage part of the corpus cardiacum of Locusta migratoria consist s of two compartments: a neural part on the haemocoelic side containin g neuronal cell bodies that are protected by a blood-brain barrier, an d a neurohaemal part adjacent to the aorta. Intracellular filling of t he neurones in the neural part with Lucifer yellow followed by confoca l laser scanning microscopy has revealed that these neurones can be di vided into several classes. None of the neurones has processes extendi ng into the glandular part of the corpus cardiacum. They are, therefor e, not directly involved in the regulation of adipokinetic cell activi ty.
