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].

Thaum muab piv cov kab kab kab thiab cov kab ntsig flatworms qhov twg muaj tseeb?
Ib tug flatworm muaj nyias, dorsoventrally flattened lub cev. Roundworms yog ntau cylindrical hauv cov duab thiab tapered mus rau qhov zoo ntawm ib kawg. Ib yam li ntawd, cov kab mob roundworms muaj ib txheej txheej txheej hu ua cuticle uas lawv tau rov ua dua thoob plaws hauv lawv lub neej thiab thaum lawv loj hlob.
Cov kab kab kab kab kab ua kab mob txaus ntshai npaum li cas?
Nyob rau hauv peb thiab tom ntej instars ntawm lawv txoj kev loj hlob, Pine processionary caterpillars yog mob heev rau daim tawv nqaij ntawm tib neegthiab lwm yam tsiaj. Kev sib cuag yooj yim nrog cov plaub hau ntawm kab ntsig tuaj yeem ua rau pob khaus hnyav (urticaria) thiab khaus qhov muag, thiab qee tus neeg yuav muaj kev fab tshuaj.
Cov tshuaj kab kab mob puas yuav ua haujlwm rau cov kab mob sib kis?
Bayer Drontal Broad Spectrum Dewormer zoo tshem tawm ntau hom kab mob hauv plab nrog rau cov kab mob tapeworms, hookworms, thiab roundworms. Kuv puas tuaj yeem kho kuv tus miv rau kab kab kab kab thiab kab kab sib chaws tib lub sijhawm?
Nyob hauv cov kab mob cov qauv no ua rau cov tshuaj tiv thaiv kab mob?
Cov qauv thiab kev ua haujlwm ntawm txheej LPShauv cov kab mob gram tsis zoo muab qhov cuam tshuam rau qee hom molecules. Qhov no ua rau cov kab mob hauv lub cev tsis muaj zog rau qee pawg ntawm cov tshuaj tua kab mob loj [28]. Cov kab mob ua rau cov tshuaj tiv thaiv kab mob li cas?
Nyob thaum lub sij hawm tu cov kab mob kab mob no nyob qhov twg?
PI (Lub Chaw Saib Xyuas Kev Loj Hlob) - Ntawm no cov niam txiv ntawm kev lag luam nteg tau rov tsim kho. (3) Grainage: Cov chaw tsim khoom uas tsis muaj kab mob coj mus muag cov noob raug tsim tawm hauv huab hwm coj los muab rau rov qab hu ua Grainages.
