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., tsim ib qho olfactory epithelium.
olfactory cells yog dab tsi thiab lawv nyob qhov twg?
Cov olfactory hlwb raug pom nyob rau hauv lub qhov ntswg epithelium(4) thiab dhau lawv cov ntaub ntawv los ntawm cov phaj cribriform (3) ntawm cov pob txha ethmoid.
olfactory cells nyob qhov twg?
Olfactory Cells nyob rau hauv thaj tsam ntawm qhov ntswg kab noj hniav. Koj nyuam qhuav kawm 13 nqe lus!
olfactory cells yog dab tsi thiab lawv ua dab tsi?
Lub olfactory epithelium, pom nyob rau hauv lub qhov ntswg kab noj hniav, muaj olfactory receptor hlwb, uas muaj tshwj xeeb cilia extensions. Lub cilia ntxiab ntxhiab moleculesthaum lawv hla dhau 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.
tib neeg muaj pes tsawg olfactory cells?
thaj chaw olfactory hauv tib neeg yog li 2.5 cm 2 dav thiab muaj ntau tus kwv yees li 50 lab receptor hlwb nrog 8–20 cilia nyob rau hauv ib txheej ntawm mucus ntawm txog 60 microns tuab, tsim los ntawm Bowmann qog nyob rau hauv lub olfactory epithelium. [1].
