Abstract
In mollusca, interactions with the environment are handled by the nervous system (including
the sense organs) and the muscular system (the muscles that making the foot and those that attach
the animal to its shell). Both systems, of course, have been of different forms in different group of
animals. In these freshwater bivalve molluscs like Lamellidens corrianus ammonia excretion play
H
an important role in the physiology; just like exogenous factors i.e. temperature, P
, salinity etc.
endogenous factors are too important for maintaining the homeostasis. Both the groups of animals
i.e. cerebral ganglia ablated and cerebral ganglionic extract injected showed pronounced effect on
ammonia excretion. Experiments were carried out in summer, monsoon and winter seasons
