TLDR
Transmission electron microscopical study of olfactory epithelium of a mud-dwelling catfish shows receptor, supporting, goblet and basal cells, which indicates that the nonciliated supporting cells also have a secretory function which is evident from the present study.Abstract:
Transmission electron microscopical study of olfactory epithelium of a mud-dwelling catfish,Heteropneustes fossilis (Bloch) shows receptor, supporting, goblet and basal cells. The receptor cells are of ciliated and microvillous type. Both ciliated and microvillous receptor cells are provided with olfactory knob. The dendrite of all the receptor cells bears many longitudinally arranged microtubules. Occurrence of the rod cell and its function is quite debatable. Specialized juctional complexes between the receptor and adjacent cells are clearly noted. The supporting cells are both ciliated and nonciliated. The ciliated supporting cells are responsible for water ventilation in the olfactory chamber as well as in the inter-lamellar spaces. This facilitates better perception of odours by the receptor cells. In addition to providing mechanical support to other cells, the nonciliated supporting cells also have a secretory function which is evident from the present study. The different stages of maturity of goblet cells are well documented. The presence of white cells in the olfactory epithelium is a very rare finding.read more

Surface ultrastructure of the olfactory rosette of an air-breathing catfish, heteropneustes fossilis (bloch)
TL;DR: The surface architecture of the olfactory rosette of Heteropneustes fossilis (Bloch) has been studied by scanning electron microscopy and the lateral surface of each o aroma lamella is identified as sensory, ciliated non-sensory and non-ciliatedNon-Sensory epithelium.

TL;DR: Olfactory rod cells differ in morphology from the known classes of olfactory sensory neuron, but express reporters driven by neuronal promoters, as they are not associated with established synaptic terminals.

The fine structure of the olfactory surface of teleostean fishes
TL;DR: The olfactory receptors of Phoxinus and Gasterosteus are of at least two distinct types: those with ciliated tips, and those with rod-shaped tips to their dendrites.
