Nyob rau hauv cov vertebrates av, suav nrog tib neeg, cov receptors nyob rau ntawm olfactory receptor hlwb, uas muaj nyob rau hauv ntau heev (million) thiab yog pawg nyob rau hauv ib tug me me cheeb tsam nyob rau hauv lub qhov ntswg kab noj hniav, tsim ib tug olfactory epithelium. olfactory epithelium Lub olfactory epithelium, pom nyob rau hauv lub qhov ntswg kab noj hniav, muaj olfactory receptor hlwb, uas muaj tshwj xeeb cilia extensions. Cov cilia ntxiab tsw ntxhiab molecules thaum lawv hla mus rau ntawm qhov chaw epithelial. Cov ntaub ntawv hais txog cov molecules ces kis tau los ntawm cov receptors mus rau olfactory noob nyob rau hauv lub hlwb. https://www.britannica.com › science › olfactory-epithelium
Olfactory epithelium | lub cev | Britannica
hom cell yog olfactory receptors?
Olfactory receptors. Cov hlwb receptor yog tiag tiag bipolar neurons, txhua tus muaj ib tug nyias dendritic pas nrig uas muaj cov cilia tshwj xeeb txuas los ntawm cov hlwv hlwv thiab cov txheej txheem ntev hauv nruab nrab uas ua rau fila olfactoria. Lub cilia muab qhov chaw hloov pauv rau tsw ntxhiab stimuli.
Puas olfactory receptors cais cov hlwb?
qauv. Tib neeg muaj li ntawm 10 thiab 20 lab olfactory receptor neurons. … Txhua olfactory receptor cell qhia tsuas yog ib hom olfactory receptor (OR), tab sis ntau yam sib cais olfactory receptor cells nthuav tawm LOSSIS uas khi tib yam tsw.
hom receptor yog dab tsiolfactory receptor?
Olfactory receptors (ORs), tseem hu ua odorant receptors, yog chemoreceptors qhia hauv cov cell membranes ntawm olfactory receptor neurons thiab muaj lub luag haujlwm rau kev tshawb nrhiav cov ntxhiab tsw (piv txwv li, Cov tshuaj uas muaj ntxhiab tsw) uas ua rau muaj kev hnov tsw.
Puas muaj pes tsawg lub hlwb nyob hauv cov 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.

Puas yog mesenchymal hlwb osteogenic hlwb?
Mesenchymal qia hlwb cog lus rau osteogenic kab thiab sib txawv rau hauv cov laus osteoblasts thiab osteocytes osteocytes Osteocytes yog cov hlwb nyob hauv cov pob txha nws tus kheej thiab yog 'entrapped' osteoblasts . Lawv yog cov post-proliferative, sawv cev rau cov neeg paub tab sib txawv tshaj plaws ntawm cov kab mob osteoblast.
Pob theca hlwb puas muaj fsh receptors?
Yog li txawm tias theca hlwb tsis muaj FSH receptors , txawm li cas los xij, lawv txawm teb tsis ncaj rau FSH nrog nce ntau lawm ntawm androgens xav tau los ntawm granulosa hlwb granulosa hlwb Ib granulosa cell lossis follicular cell yog a somatic cell ntawm kev sib deev qaum uas yog ze rau cov poj niam gamete (hu ua oocyte lossis qe) hauv zes qe menyuam ntawm cov tsiaj.
Puas yog olfactory receptors neurons?
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:
Puas yog cov hlwb eukaryotic thawj lub hlwb?
Thawj lub eukaryotic hlwb - cov hlwb nrog lub nucleus ib sab hauv daim nyias nyias - khi organelles - tej zaum hloov zuj zus kwv yees li 2 billion xyoo dhau los . Qhov no tau piav qhia los ntawm txoj kev xav endosymbiotic endosymbiotic txoj kev xav Txoj kev xav tau hais tias mitochondria, plastids xws li chloroplasts, thiab tej zaum lwm cov organelles ntawm eukaryotic hlwb yog nqis los ntawm yav tas los dawb-nyob prokaryotes (ntau ze ze rau cov kab mob ntau dua li archaea) coj
Puas yog cov paj hlwb genitofemoral yog cov paj hlwb peripheral?
Cov paj hlwb genitofemoral hais txog paj hlwb uas pom hauv plab. Nws cov ceg, ceg ntawm qhov chaw mos thiab cov ceg femoral muab kev nkag siab rau sab sauv sab xub ntiag, nrog rau daim tawv nqaij ntawm lub qhov quav sab hauv ntawm cov txiv neej thiab mons pubis hauv cov poj niam.
