Thaum neurotransmitter molecules khi rau receptors nyob rau ntawm cov neuron's dendrites, ion channel qhib. Ntawm excitatory synapses, qhov qhib no tso cai rau cov ions zoo nkag mus rau hauv cov neuron thiab ua rau depolarization ntawm daim nyias nyias-ib qho kev txo qis hauv qhov sib txawv ntawm qhov sib txawv ntawm sab hauv thiab sab nraud ntawm neuron.
Yuav ua li cas yog ib qho excitatory neurotransmitter ua rau depolarisation ntawm post synaptic membrane?
Lub excitatory neurotransmitters tsim ib qho kev nce hauv zos permeability ntawm sodium ion channels. Raws li qhov tshwm sim hauv ntau cov sodium ions ntws nyob rau hauv uas ua rau lub zos depolarisation uas yog hu ua excitatory postsynaptic muaj peev xwm (EPSP). Qhov no ua rau muaj qhov tshwm sim ntawm post synaptic cell los tua qhov muaj peev xwm ua.
Dab tsi neurotransmitters ua rau depolarization?
Tus acetylcholine receptors hauv cov leeg nqaij pob txha hu ua nicotinic acetylcholine receptors. Lawv yog cov ion channel uas qhib rau hauv teb rau acetylcholine khi, ua rau depolarization ntawm lub hom phiaj cell.
Tus neurotransmitter pib depolarization li cas?
Tom qab tso rau hauv cov synaptic cleft, neurotransmitters cuam tshuam nrog receptor proteins ntawm daim nyias nyias ntawm postsynaptic cell, ua rau ionic channels ntawm daim nyias nyias kom qhib lossis kaw. Thaum cov channel no qhib, depolarization tshwm sim, ua rau covpib ntawm lwm qhov kev nqis tes ua.
Puas excitatory neurotransmitters depolarize?
Cov neurotransmitters no khi rau cov receptors nyob rau ntawm postsynaptic membrane ntawm qis neuron, thiab, nyob rau hauv cov ntaub ntawv ntawm ib tug excitatory synapse, yuav ua rau ib tug depolarization ntawm postsynaptic cell.
