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.
