Thaum lub sijhawm depolarization, sab hauv ntawm cov neuron's membrane ua tsis zoo. Neurons nyob rau hauv CNS tau koom ua pawg ua haujlwm. Muaj zog stimuli ua rau lub amplitude ntawm kev ua muaj peev xwm generated nce. Cov oligodendrocytes tuaj yeem myelinate ntau axons.

Thaum lub hauv paus ntawm daim nyias nyias ua tsis zoo?

Yog tias sab hauv ntawm tes ua tsis zoo (piv txwv li, qhov muaj peev xwm txo qis hauv qab lub peev xwm so), cov txheej txheem hu ua depolarization.

Qhov twg hauv qab no tshwm sim thaum lub sijhawm depolarization?

Nyob rau hauv tus txheej txheem ntawm depolarization, lub negative internal charges ntawm lub cell ib ntus ua ntau zoo (tsis zoo). Qhov kev hloov pauv ntawm qhov tsis zoo mus rau qhov muaj peev xwm zoo dua tuaj yeem tshwm sim thaum lub sijhawm ua haujlwm ntau, suav nrog kev ua haujlwm muaj peev xwm.

Thaum depolarization ntawm cov cell membrane mus txog qhov pib qhov twg hauv qab no tshwm sim quizlet?

Cov ntsiab lus hauv cov txheej no (15) Thaum depolarization ntawm cell membrane mus txog qhov pib, qhov twg hauv qab no tshwm sim? Sodium ion channels qhib.

Puas yog qhov ua tau tshwm sim los ntawm kev hloov pauv permeability hauv cov ntshav plasma?

Thaum lub sijhawm depolarization, sab hauv ntawm lub paj hlwb ua rau tsis zoo. Yog hais tias cov neuron membrane ua ntau permeable rau Na +, Na + yuav thauj hla cov membrane, ua rau lub cell depolarize. … Lub peev xwm ua tau yog tshwm sim los ntawm kev hloov pauv permeability hauv plasma membrane.
