Lub olfactory epithelium muaj ob thaj chaw, txhua qhov muaj thaj tsam li 5 cm 2, nyob nyob rau hauv lub ru tsev ntawm qhov ntswg kab noj hniav. Lub epithelium nto yog txhais los ntawm ib tug nyias perforated pob txha phaj, lub cribriform phaj, uas cais lub qhov ntswg kab noj hniav ntawm lub hlwb.
Nrhiav olfactory epithelium nyob qhov twg?
Lub olfactory epithelium, pom hauv lub qhov ntswg kab noj hniav, muaj olfactory receptor hlwb, uas muaj cov tshwj xeeb cilia txuas ntxiv. 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.
Lub olfactory epithelium nyob qhov twg?
Lub olfactory epithelium nyob qhov twg? Qhov zoo tshaj ntawm qhov ntswg kab noj hniav, npog qhov tsis zoo ntawm cov phaj cribriform.
olfactory neurons nyob qhov twg?
Olfactory sensory neurons, nyob hauv qhov ntswg epithelium, ntes thiab xa cov ntaub ntawv ntxhiab mus rau hauv nruab nrab paj hlwb. Qhov no yuav tsum tau hais tias cov neurons no tsim cov kev sib txuas neuronal tshwj xeeb nyob rau hauv lub qhov muag olfactory thiab nthuav qhia cov receptors thiab cov cim taw qhia tshwj xeeb rau cov haujlwm no.
Cov pob txha twg puas yog qhov olfactory epithelium nyob?
Cov olfactory hlwb muaj nyob rau hauv lub qhov ntswg epithelium (4) thiab kis lawv cov ntaub ntawv los ntawm cribriform phaj (3) ntawm pob txha ethmoid.

Qhov twg hu ua pavement epithelium?
Nyob rau hauv cov hlab plawv xws li hauv ob sab phlu capillaries lossis sab hauv ntawm lub plawv, yooj yim squamous epitheliumtshwj xeeb hu ua endothelium. Cells yog tiaj nrog flattened thiab oblong nuclei. Nws tseem hu ua pavement epithelium vim nws cov pobzeb zoo li zoo li.
Kev tsis ncaj ncees nyob qhov twg yog qhov hem rau kev ncaj ncees nyob txhua qhov chaw?
Martin Luther King tau hais tias: “Kev tsis ncaj ncees nyob txhua qhov chaw yog kev hem thawj rau kev ncaj ncees nyob txhua qhov chaw. Peb raug ntes nyob rau hauv ib tug inescapable network ntawm kev sib nrig sib pab, khi nyob rau hauv ib lub tsoos tsho ntawm txoj hmoo.
Qhov twg yog qhov tsis txaus ntseeg nyob qhov twg?
Yuav muaj ob lub cev tsis zoo nyob rau hauv lub midbrain. Lawv yog symmetrically positioned, ib tug nyob rau ntawm ob sab ntawm lub midline ntawm lub hlwb, thiab lawv tsim ob lub pob nyob rau hauv lub posterior nto ntawm lub paj hlwb nyob rau hauv qab ntawm lub superior colliculi.
Qhov twg tag nrho cov nqi hluav taws xob nyob ntawm qhov kev siv nyiaj siab tshaj plaws yog qhov twg?
marginal utility is zero. Tag nrho cov nqi hluav taws xob yog siab tshaj thaum marginal utility yog xoom. Qhov no yog vim muaj ntau txoj cai ntawm kev txo qis marginal utility uas hais tias tus neeg siv khoom noj ntau thiab ntau qhov zoo, qhov ntxiv rau tag nrho cov nqi hluav taws xob poob.
Cov kab mob olfactory nyob qhov twg?
Nyob rau hauv cov vertebrates av, suav nrog tib neeg, cov receptors nyob rau ntawm olfactory receptor hlwb, uas tam sim no nyob rau hauv ntau heev (million) thiab yog pawg nyob rau hauv ib cheeb tsam me me nyob rau sab nraum qab ntawm lub qhov ntswg kab noj hniav.
