27732 ); preopercular scale rows 6-8 (Ref. (D) Part of the transverse section of ventral telencephalon showing projections of olfactory tract comprising medial olfactory tract (MOT) and lateral olfactory tract (LOT). Scales minute. … In general intestinal morphology of fish can be influenced by feeding habits, frequency of food intake as well as by body size and shape [4, 7]. which consisted of polymorphism of receptors, supporting, labyrinth, mucous and During raking behavior, the prey is held fixed in the MJA, the neurocranium is elevated, and the pectoral girdle is retracted. Scale bar = 50μm. The olfactory apparatus of C. punctata comprises of olfactory rosette, olfactory nerve, and olfactory bulb. International Journal of Pharma and Bio Sciences. Histology, ultrastructure, intestine, teleost, Notopterus notopterus 1. notopterus (Pallas) has been investigated in serial sections specially prepared for the purpose. Morphology: Body highly compressed and dorsal and ventral profile almost equally convex. Location of glomerular layer (GL), mitral cell layer (MCL), granular cell layer (GCL), lateral olfactory tract (LOT) and medial olfactory tract (MOT) is also depicted. With the help of neuronal staining technique, polymorphism of OSNs in N. notopterus was studied. 4832).Adults inhabit standing and sluggish waters of lakes, floodplains, canals and ponds (Ref. Olfactory organs of fishes show wide range of variations depending upon the systematic groups and ecological habitats. Scale bar = 50μm. Olfactory epithelium is connected to the bulb by a short olfactory nerve. As in other vertebrates, olfactory sensory neurons (OSNs) in fishes are the main components of sensory part of olfactory epithelium that relay olfactory information (smell and taste) to the brain. With the help of Haematoxylin-Eosin and Kluver and Barrera (1953) staining techniques, organization of the olfactory epithelium and olfactory bulb was studied. Osteoglossomorph fishes are characterized by having three sets of jaws: a mandibular jaw apparatus (MJA) anteriorly, a pharyngeal jaw apparatus (PJA) posteriorly, and a tongue‐bite apparatus (TBA) associated with basihyal and parasphenoid teeth. De Aziatische mesvis staat op de Rode Lijst van de IUCN als niet bedreigd, beoordelingsjaar 2009. 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). OE of C. punctatus was examined through LM and SEM. De Aziatische mesvis (Notopterus notopterus) is een straalvinnige vissensoort uit de familie van mesvissen (Notopteridae). Olfactory bulb is a concentrically arranged four layered structure with olfactory nerve layer on the outermost side followed by glomerular layer, mitral cell layer and granular cell layer. phases of Eutropiichthys vacha (Hamilton, 1822) were described by light Histology of the urinogenital papilla ofNotopterus notopterus (Pallas) Shyama Sharma F.A.Z. The structural components of the olfactory Morphology, Morphometry and Neuroanatomy of the Olfactory Epithelium and the Olfactory Bulb of a Featherback Fish, Notopterus notopterus The olfactory bulbs comprise four concentric layers, which from outside toward the center are olfactory nerve layer, a glomerular. Notopterus notopterus is een mesvis die voorkomt in de grote rivieren van India, Myanmar, Thailand, Laos, Vietnam, Maleisië en Indonesië. Description. In between the sensory receptor cells, supporting cells formed a mosaic shielding them from mechanical abuse, It has recently been shown that a chronic copper exposure induces specific degeneration of olfactory receptor cells in rainbow trout; however, the exact mechanism of action of the metal is not yet known. 12693).Undertake 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 (Ref. Recent findings are concerned with (1) the organization of the olfactory bulb (Ichikawa, 1976; Kosaka and Hama, 1979, 1980, 1981, 1982; Kosaka, 1980; Oka, 1983; Satou et al., 1983; Fujita et al., 1988) and of the telencephalic olfactory regions (Scalia and Ebbesson, 1971; Finger, 1975; Ichikawa, 1975; Oka, 1980; Bass, 1981a,b; Davis et al., 1981; Ebbesson et al., 1981; Murakami et al., 1983; Bartheld et al., 1984; Fujita et al., 1984; Levine and Dethier, 1985), and (2) specific odorants (pheromones) related to the reproductive functions and their effects on the olfactory system (Dulka et al., 1987; Sorensen et al., 1987, 1988; Stacey et al., 1987; Fujita et al., 1991).
