Ob tus utricle thiab cov saccule muab cov ntaub ntawv hais txog acceleration. Cov qhov sib txawv ntawm lawv yog tias cov utricle yog ntau rhiab heev rau kab rov tav acceleration, whereas lub saccu yog rhiab heev rau ntsug nrawm.
Kuj tseem paub yog, qhov utricle thiab saccule ua li cas?
Cov utricle thiab saccule yog ob lub cev otolith hauv pob ntseg sab hauv. Lawv yog ib feem ntawm qhov sib npaug (cov labyrinth membranous) hauv lub vestibule ntawm lub pob zeb labyrinth (chav me me oval). Lawv siv cov pob zeb me me thiab cov kua nplaum nplaum los txhawb cov plaub hau kom pom kev txav thiab kev taw qhia.
Ib yam li ntawd, utricle thiab saccule ua haujlwm li cas? Muaj yog Ob pawg ntawm cov kabmob kawg hauv pob ntseg, lossis labyrinth: cov kwj dej semicircular, uas teb rau kev txav mus los (nrawm nrawm); thiab cov utricle thiab saccule tsis pub dhau lub vestibule, uas teb rau hloov pauv txoj haujlwm ntawm lub taub hau nrog kev hwm rau Lub ntiajteb txawj nqus (linear acceleration).
Kuj tseem paub yog, sacule thiab utricle muaj dab tsi?
Cov utricle thiab saccule txhua muaj macula, ib qho khoom nruab nrog uas muaj cov kab mob ntawm cov plaub hau npog los ntawm gelatinous membrane muaj cov ntsiab lus ntawm calcium carbonate, hu ua otoliths.
Dab tsi yog otolith hauv tib neeg?
το-, ōto- pob ntseg + λ? ´θος, líthos, pob zeb), tseem hu ua statoconium lossis otoconium lossis statolith, yog cov qauv calcium carbonate hauv saccule lossis utricle ntawm lub pob ntseg sab hauv, tshwj xeeb hauv vestibular system ntawm vertebrates. Lub saccule thiab utricle, nyeg, ua ke ua otolith cev.

Dab tsi yog qhov sib txawv ntawm qhov kev cia siab rau qhov ntim thiab qhov ntim cia tseg?
Qhov ntim cia tseg (ERV) yog cov pa ntxiv uas tuaj yeem nqus tau tom qab ua pa ib txwm. Nws yog qhov nyiaj khaws cia uas tuaj yeem nqus tau dhau qhov uas ib txwm muaj. Hloov pauv, qhov ua rau lub zog cia siab (IRV) yog qhov ntxiv ntawm huab cua uas tuaj yeem nqus tau tom qab nqus tau ib txwm
Dab tsi yog qhov sib txawv thiab qhov zoo sib xws ntawm cov khoom sib tsoo thiab qhov kov zoo?
Dab tsi yog qhov sib txawv thiab qhov zoo sib xws ntawm 'crude' kov thiab 'nplua' kov qhov hnov? Nyuaj kov yog hais txog kev nkag siab los ntawm kev txhawb nqa ntawm cov neeg txais khoom ntawm qhov tsis nkag siab nrog cov teb loj. Hauv kev sib piv, kev kov zoo yog hais txog cov neeg txais khoom ntawm kev nkag siab siab nrog cov chaw txais me me
Dab tsi yog qhov txawv ntawm ER ntxhib thiab du ER Dab tsi yog ER ua qhov sib txawv hauv txhua kis?
Ob qho tib si du thiab ntxhib endoplasmic reticulum pab hauv kev tsim thiab khaws cov proteins Qhov sib txawv tseem ceeb yog tias ib qho muaj ribosomes rau nws thiab lwm yam tsis. Rough ER zoo li cov nplooj ntawv. RER sib sau ua (ua) thiab ntim cov protein. RER tau txuas nrog lub nuclear membrane
Dab tsi yog qhov txawv ntawm cheeb tsam sib txawv thiab thaj tsam tas li ntawm ib qho tshuaj tiv thaiv?
Cov cheeb tsam sib txawv no, muaj li ntawm 110-130 amino acids, muab cov tshuaj tiv thaiv kab mob nws qhov tshwj xeeb rau kev khi antigen. Cov cheeb tsam sib txawv suav nrog qhov kawg ntawm lub teeb thiab cov saw hnyav. Lub cheeb tsam tas li txiav txim siab cov txheej txheem siv los rhuav tshem antigen
Dab tsi yog qhov txawv ntawm qhov tseeb qhov pib thiab qhov sib txawv qhov pib?
Qhov pib tsis txaus yog qhov tsawg kawg ntawm kev txhawb siab xav tau rau ib tus neeg kom pom qhov kev txhawb siab 50 feem pua ntawm lub sijhawm. Qhov sib txawv ntawm qhov sib txawv yog qhov sib txawv me tshaj hauv kev txhawb nqa uas tuaj yeem kuaj pom 50 feem pua ntawm lub sijhawm
