Abstract

The cellular organisation of the olfactory rosettes of Etroplus suratensis was studied by light and scanning electron microscopy. The oval shaped olfactory rosette of the fish consists of 12 lamellae radiating from a central raphe. The olfactory lamellae are comprised of restricted areas of sensory epithelium and broad areas of non-sensory epithelium in the apical, middle, and basal regions. The sensory epithelium contains three types of receptor cells: microvillus, ciliated, and rod cells, as well as labyrinth cells and supporting cells. The non-sensory epithelium consists of stratified epithelial and mucous cells. The transitional region between the sensory and non-sensory epithelium consists of ciliated receptor cells, mucous cells, and stratified epithelial cells. The different cells on the olfactory epithelium were discussed regarding the functional significance of the fish concerned. (Folia Morphol 2010; 69, 3: 154-159)
