Abstract
The neurosecretory system of the Indian white prawn, Penaeus indicus was examined under light and transmission electron microscopy. Four morphological types of neurosecretory cells were identified: GN (giant neuron), A, B, and C. The characteristics of these cells, together with their histochemical properties, are described. All neurosecretory cells displayed cyclic secretory activity, and -based on the presence of stainable granules, vacuoles and glial cells - three secretory cycle phases were noted. The distribution of the neurosecretory cell groups in the eyestalk and brain, plus the tritocerebral, subesophageal, thoracic and abdominal ganglia are described and mapped. GN cells were absent from the X-organs of the eyestalk, but they dominated in all the other ganglia. Neurosecretory material was found to be haloed dense core granules with diameters between 1400 and 1600 A.
