    • Abstract


      Desiccation engenders “super elevation” in the osmotic concentration of the body fluid which eventually provokes characteristic alterations in the functional activity of the ventral nerve cord-neurosecretory system. Enhancement in the number of deep stained cells and partial to acute depletion in association with interruption in axonal transport in moderately stained cells are some of the interesting features revealed in course of this investigation. The results indicate a correlation between the neurosecretory mechanism and ecophysiological bearing.
