Purpose In C. punctata, olfactory rosette is oval in shape peculiarly do not show central raphe in olfactory rosette. Morphology, Morphometry and Neuroanatomy of the Olfactory Epithelium and the Olfactory Bulb of a Featherback Fish, Notopterus notopterus … Sensory region shows ciliated, microvillous, crypt receptor cells, supporting cells and basal cells. Olfactory receptor cells are of two types microvillous and ciliated. (B) Magnified view of the olfactory epithelium (OE) showing median raphe (R). (B) In situ photograph of olfactory organ with brain of Notopterus notopterus showing; cerebrum (C), cerebellum (CEB); olfactory bulb (OB), olfactory epithelium (OE), optic lobe (OptL), olfactory tract (OT) and spinal cord (SPC). Introduction The fish digestive tract shows a marked diversity of both morphology and function [5, 9]. Conclusion The adductor mandibulae, hypaxialis, epaxialis, and posterior intermandibularis muscles are all highly active, but only very low activity is observed in the sternohyoideus muscle. Results This, Background These fishes live in freshwater or brackish environments in Africa, and South and Southeast Asia. Cells of olfactory bulb are organized in four concentric layers. Next towards deeper part is mitral cell layer which comprises larger multipolar mitral cells. OE of C. punctatus was examined through LM and SEM. The ciliated OSNs have basally situated somata and long, thin dendrites with a few apically arranged cilia while microvillous OSNs have somata located midway in the epithelium and thick moderate-length dendrites with microvilli. (C) Transverse section of the olfactory epithelium showing olfactory lamellae (OlfL) radiating from the central raphe (R) and melanophores (M). Found in clear streams and enters brackish waters .

(E) Magnified view of the sensory and nonsensory regions of the olfactory lamellae showing basal cell (BC), basal lamina (BL), central core (CC)/lamina propria (LP), ciliated nonsensory cell (ciNSC), crypt olfactory receptor cell (crORC), ciliated olfactory receptor cell (ciORC), melanophore (M), microvillous olfactory receptor cell (mORC) and supporting cell (SC). All rights reserved. In Labeo rohita [5], N. notopterus. Olfactory receptor cells, Cytoarchitectonic pattern of the telencephalon of a dwarf snakehead, Channa gachua, is studied by serial transverse sections of the brain (Kluver and Barrera staining). OSN polymorphism reported in the present work indicates that it is a fairly conserved trait throughout the evolution of teleosts. Olfactory epithelium comprises of sensory and non-sensory regions. The electrical signal is subsequently transmitted to the higher-order nervous system, where the sensory perception of odours is produced. MATERIALS AND METHODS Live specimens of the Indian freshwater fish, Notopterus notopterus (about 30 fishes) were collected from Bheema river situated around 45 km, away from Kalaburgi and transported in are of two types microvillous and ciliated.

Using X-ray microanalysis in transmission electron microscopy, we have studied the distribution of metal in the olfactory system of fish exposed for 15, 30 and 60 days to 20 μg/l of copper. The Working off-campus? post-spawning phases was characterized by considering the tallness and architecture With … The elongated olfactory rosette lied at the bottom of chamber and supported with 54-56 lamellae on either side of the central narrow raphe. Hematological and some biochemical contents of the blood in relation to physico-chemical characteristics of the water have been studied in the fresh water fish, Notopterus notopterus. 1 Proceedings of the Indian Academy of Sciences - Section B volume 66 … Scale bar = 50μm. 1. Undertakes localized lateral migrations from the Mekong River to floodplains during the flood season and back to the mainstream or other permanent water bodies during the dry season . Folding on the olfactory epithelium of lamellae increases the surface area of epithelium as well as sensitivity and efficiency of olfactory system [2. phases of Eutropiichthys vacha (Hamilton, 1822) were described by light Lateral Lines: Interrupted: No Scales on lateral line: Pored lateral line scales: Scales in lateral series: Cytological status of olfactory epithelium during different reproductive 37770).
