Olfactory receptor neurons (ORNs) yog bipolar neurons uas tau qhib thaum huab cua molecules hauv kev tshoov siab huab cua khi rau olfactory receptors (ORs) qhia ntawm lawv cilia. Cov ORs yog rau G-protein-coupled receptor superfamily. ORNs nyob rau hauv siab nyob rau hauv lub qhov ntswg vault nyob rau hauv lub olfactory epithelium olfactory epithelium Lub olfactory epithelium yog tsim los ntawm peb hom ntawm tes: basal hlwb, olfactory sensory neurons, thiab sustentacular (los yog txhawb) hlwb. Lub olfactory sensory neurons yog bipolar neurons sensing ib puag ncig tshuaj. https://www.sciencedirect.com › topics › olfactory-epithelium

hom neurons twg yog olfactory receptor hlwb?
Olfactory receptor neurons (ORNs) yog bipolar neurons uas tau qhib thaum huab cua molecules hauv kev tshoov siab huab cua khi rau olfactory receptors (ORs) qhia ntawm lawv cilia. Cov ORs yog rau G-protein-coupled receptor superfamily. ORNs nyob rau hauv siab nyob rau hauv lub qhov ntswg qhov ntswg nyob rau hauv lub olfactory epithelium.
Puas olfactory receptors muaj tseeb neurons?
Olfactory neurons yog bipolar neurons (neurons nrog ob txheej txheem los ntawm lub cev ntawm tes). Txhua tus neuron muaj ib qho dendrite faus rau hauv olfactory epithelium; ncua ntawm no dendrite yog 5 mus rau 20 receptor-laden, plaub hau zoo li cilia uas ntxiab tsw ntxhiab molecules. Lub sensoryreceptors ntawm cilia yog cov proteins.
Puas yog olfaction yog neuron?
Olfactory sensory neurons , nyob rau hauv lub qhov ntswg epithelium, ntes thiab xa cov ntaub ntawv tsw qab mus rau hauv nruab nrab lub paj hlwb. Qhov no xav kom cov neurons daim ntawv tshwj xeeb neuronal kev sib txuas hauv olfactoryqhov muag thiab nthuav qhia cov receptors thiab cov cim qhia txog cov khoom siv tshwj xeeb rau cov haujlwm no.
Puas yog olfactory neurons bipolar?
Lub olfactory epithelium suav nrog ntau hom cell sib txawv (Daim duab 15.5A). Qhov tseem ceeb tshaj plaws ntawm cov no yog olfactory receptor neuron,bipolar cell uas ua rau nce mus rau qhov me me, tsis muaj axon ntawm nws qhov chaw basal uas xa cov ntaub ntawv olfactory hauv nruab nrab.
