Study of Neurosecretory Cells of Freshwater Bivalve: Lamellidens Corrianus (Lea)
Journal Title: Bulletin of Pure and Applied Sciences Sec. A-Zoology - Year 2018, Vol 37, Issue 1
Abstract
In the freshwater bivalve like Lamellidens corrianus neurosecretory cells have been detected in the cerebral, pedal and visceral ganglia. The number of functions of hormones/neurohormones of freshwater bivalves known at the moment is still rather small. In contrast the basic mechanism of some type of neurosecretory cells of gastropods are known in great detail, this is especially due to the fact that in some gastropods these neurons like their conventional neurons are giant cells. For this reason they are highly suitable for neurophysiological studies. The great progress made in this field and the importance of this work for neuroendocrinology in general. To extend the knowledge in this field, the present work has been undertaken on the freshwater bivalve species Lamellidens corrianus which is abundantly distributed along the banks of Godavari river at Jayakwadi backwaters (Nath sagar) near Paithan in Aurangabad district. The histological details of neurosecretory cells (NSCs) in cerebral, pedal and visceral ganglia have been studied which reveals the presence of Type A & Type B cell (with nucleus, nucleolus and axon) predominantly secrete neurosecretory material. The results are converse in illumination of neurosecretory changes.
