Depolarization thiab hyperpolarization tshwm sim thaum ion channels hauv daim nyias nyias qhib lossis kaw, hloov lub peev xwm ntawm cov ions tshwj xeeb nkag mus lossis tawm ntawm lub xovtoojPiv txwv li: qhib cov channel uas cia cov ions zoo ntws tawm ntawm lub xovtooj (lossis tsis zoo ions ntws hauv) tuaj yeem ua rau hyperpolarization.
Dab tsi ua rau depolarization ntawm neuron?
Depolarization yog tshwm sim thaum raug nqi sodium ions maj nrawm rau hauv cov neuron nrog qhib cov hluav taws xob-gated sodium channels. Repolarization yog tshwm sim los ntawm kev kaw ntawm sodium ion channels thiab qhib cov poov tshuaj ion channels.
Yuav ua li cas rau depolarize ib neuron?
Repolarization feem ntau tshwm sim los ntawm kev txav ntawm qhov zoo them K+ ions tawm ntawm lub cell… Cov theem no tshwm sim tom qab lub xovtooj mus txog nws qhov siab tshaj plaws voltage los ntawm depolarization. Tom qab repolarization, lub cell hyperpolarizes thaum nws mus txog so membrane peev xwm (−70 mV){in neuron −70 mV}.
Yuav ua li cas hauv qab no yuav ua rau lub cev tsis muaj zog?
Yuav ua li cas hauv qab no yuav ua rau lub hlwb puas tsuaj? nce daim nyias nyias permeability rau sodium.
txhais li cas rau depolarize ib neuron?
txav ntawm lub cell daim nyias nyias mus rau qhov muaj txiaj ntsig zoo dua (piv txwv li txav ze ze rau xoom los ntawm so lub peev xwm membrane). Thaum ib tug neuron yog depolarized, nws yuav muaj peev xwm tua hluav taws ntau dua. Lub Ib Hlis 10, 2021 / Guest User/

Yuav ua li cas qhia ib tug txiv neej ntoo nquab ntawm ib tug poj niam?
Poj niam zoo nkaus li nyias nyias thiab pale dua txiv neej tab sis ob leeg muaj daim nqi liab liab nrog lub taub daj. Cov noog me me muaj cov cim tis neeg laus tab sis tsis muaj lwm yam xim . Koj qhia li cas qhov txawv ntawm tus txiv neej thiab poj niam nquab ntoo?
Yuav ua li cas ib tug ntse shinned hawk tua ib tug qaib?
Hawk tawm tsam yog ib qho ntawm cov nqaij qaib, tshwj xeeb tshaj yog me me, bantam breeds thiab cov noog hluas. … Ib tug hawk feem ntau tsuas tua ib tug noog ib hnub xwb. Hawks plam cov noog, tso cov plaub rau hauv av, vim lawv tsis nyiam noj plaub .
Yuav ua li cas ib tug loon yuav noj ib tug me nyuam os?
Kuv xav tias nws puas tau ntes tau ib tug ducklings, yog li kuv googled " do loons noj menyuam ducks". … Nyem qhov no mus nyeem txog “loon alligators”. Thaj, loons yuav tua cov neeg laus ducks thiab txawm Canada Geese, thiab tsis tu ncua siv underwater ste alth nyob rau hauv lawv tua .
Puas yog tug tug tug zoo le lub nkoj?
Ntawm no yog qhov kuv tau hais rau kuv cov neeg ua haujlwm: Ib lub nkoj muaj lub cev V-shaped thiab tsim rau siv rau hauv qhov qhib, dej tob. Lub nkoj muaj ib lub nkoj tiaj tus thiab yog tsim los ua haujlwm nyob rau hauv cov dej ntiav ntiav ntawm cov dej ntws hauv dej.
Qhov twg yog hluav taws xob impulses uas taug kev los ntawm neuron mus rau neuron?
Action Potential . An qhov muaj peev xwm ua tau, tseem hu ua lub paj hlwb impulse, yog ib qho hluav taws xob uas taug kev ntawm daim nyias nyias ntawm cov neuron. Nws tuaj yeem tsim tau thaum lub neuron lub membrane muaj peev xwm hloov pauv los ntawm cov cim tshuaj lom neeg los ntawm lub cell ze .
