olfactory receptors nyob qhov twg quizlet?
Cov receptors lub luag haujlwm rau olfaction nyob hauv lub olfactory epithelium. Olfactory receptor neurons synapse nrog neurons ntawm olfactory noob nyob rau hauv lub paj hlwb cortex.
Lub luag haujlwm thiab qhov chaw ntawm olfactory receptors yog dab tsi?
Olfactory receptors yog tuaj yeem ntes cov ntxhiab tsw ntawm huab cua uas nkag mus rau hauv qhov ntswg kab noj hniav thiab khi rau olfactory receptors. Kev ua kom cov olfactory receptors ua rau olfactory receptor neurons xa cov impulse mus rau lub hlwb olfactory system.
Koj ua li cas qhib olfactory receptors?
Sim qhov no: pib los ntawm kev xaiv plaub yam uas koj nyiam, xws li kas fes tshiab, txiv tsawb, xab npum lossis tshuaj zawv plaub hau thiab cheese. Tom qab ntawd txhua hnub, siv sijhawm ob feeb kom dhau mus thiab hnov qab txhua tus ntawm tus kheej txhawm rau txhawb cov receptors hauv koj lub qhov ntswg.
Tib neeg muaj pes tsawg hom olfactory receptors?
Tib neeg siv ib tsev neeg ntawm ntau tshaj 400 olfactory receptors (ORs) txhawm rau kuaj cov ntxhiab tsw, tab sis tam sim no tsis muaj tus qauv uas tuaj yeem kwv yees olfactory xaav los ntawm cov qauv kev ua haujlwm.
