Histophysiological Studies on the Olfactory Epithelium of Banded Pearl Spot Etroplus suratensis (Bloch, 1790)

Author(s): Saroj Kumar Ghosh, Padmanabha Chakrabarti

Abstract: The histoarchitecture and function of various cells lining the olfactory epithelium of Etroplus Suratensis (Bloch, 1790) was investigated with light microscope. Histologically, the olfactory lamella consisted of two layers of epithelium separated by central core. On the basis of cellular organization and their distribution in the surface of each lamella is characterized by sensory and non-sensory regions. Four distinct type of receptor cells (primary receptor cells, secondary receptor cells, microvillous cells and rod cells) as well as mast cells and basal cells were identified in the sensory epithelium. The non-sensory epithelium was provided with mainly stratified epithelial cells and large number of mucous cells. The different cells on the olfactory epithelium were correlated in relation to their role in olfaction.
