S altatory conduction (los ntawm Latin s altare, dhia lossis dhia) yog kev nthuav tawm ntawm kev ua haujlwm muaj peev xwm raws myelinated axons los ntawm ib qho ntawm Ranvier mus rau ntawm lub tom ntej, nce kev coj ua. Kev tshaj tawm ntawm kev muaj peev xwm ua tau.

Yuav ua li cas ua rau s altatory conduction?

Cov teeb liab hluav taws xob mus nrawm dua hauv axons uas tau thaiv nrog myelin. … Txoj kev muaj peev xwm taug kev hauv axon "dhia" ntawm node mus rau ntawm. Qhov no yog hu ua s altatory conduction uas txhais tau tias "leap." S altatory conduction yog txoj hauv kev nrawm dua rau kev taug kev hauv axon dua li taug kev hauv axon yam tsis muaj myelin.

Yuav ua li cas yog s altatory conduction thiab nws tshwm sim li cas?

S altatory conduction piav qhia txog txoj kev hluav taws xob impulse hla ntawm node mus rau ntawm qhov ntev ntawm ib qho axon, ua kom lub zog tuaj txog ntawm lub zog ntawm lub paj hlwb hauv kev sib piv nrog cov qeeb qeeb qeeb zuj zus ntawm depolarization kis mus rau ib qho tsis muaj myelinated axon.

S altatory yog dab tsi?

1 archaic: of or related to dance. 2: nce mus los ntawm leaps es tsis yog los ntawm kev hloov maj mam: tsis txuas ntxiv.

S altatory propagation ua haujlwm li cas?

Kev tuaj txog ntawm cov ions zoo ntawm node depolarises no ntu ntawm axon ib yam nkaus, pib ua lwm yam peev xwm. Cov txheej txheem no rov ua dua, tso cai rau qhov kev txiav txim muaj peev xwm nthuav tawm sai sai raws li axon, ua tau zoo ' dhia' ntawm cov nodes. Qhov no 'dhia' mechanism yog hu ua s altatory conduction.
