WebDec 1, 2024 · The olfactory organ is an important chemoreceptor in vertebrates. However, the sexual disparities in gene expression patterns in the olfactory organ in fish remain unstudied. Here, we conducted a transcriptome analysis of the olfactory epithelium (OE) of male and female blunt snout bream (Megalobrama amblycephala) to identify the … WebThe olfactory receptor neurons (ORNs) were recognised by their shape, size, staining intensity, cilia and axon projections, but were guided by previous publications in other teleosts (Hamdani et ...

Webnonsensory epithelium. Ciliated olfactory receptor neuron and microvillous olfactory receptor neuron are observed in both fish with the former being more abundant. The population of receptor neurons is estimated to be ~3.0 and ~7.7 million in opah and dolphin fish respectively. Ciliated nonsensory cell is rare or absent in all lamellae WebJun 1, 2007 · Abstract. Recent developments in the functional anatomy and physiology of the fish olfactory system reveal three parallel pathways from the sensory epithelium, via the olfactory bulb to the telencephalon. There are three morphological types of sensory neurones spread in a seemingly overlapping arrangement in the olfactory epithelium.
WebMost fish have sensitive receptors that form the lateral line system, which detects gentle currents and vibrations, and senses the motion of nearby fish and prey.

Crypt olfactory receptor neurons (ORNs) are a third type of chemosensory neuron along with ciliated and microvillous ORNs in the olfactory epithelium of fishes, but their functional role is still unknown. To investigate their odorant response properties and possible transduction pathways, we recorded crypt ORN activity with …
Web1979). The fish olfactory organ is particularly vulnerable to toxicants since its receptor cells are directly in contact with the externa1 environment. The olfactory receptor cells are bipolar neurons with a ciliated or microvillar dendrite emerging at the epithelial surface and with an axon ending in the olfactory bulb, which is the first relay WebH & E staining, the olfactory bulb showed six well delineated layers, namely, the nerve fiber layer, glomeru- lar layer, external plexiform layer, mitral cell layer, in- ternal plexiform layer ...
