Excitatory neurotransmitters : Cov hom no cov neurotransmitters muaj zoo siab cuam tshuam rau cov neuron, txhais tau tias lawv ua rau muaj qhov tshwm sim uas cov neuron yuav tua hluav taws muaj peev xwm. Qee qhov loj excitatory neurotransmitters muaj xws li epinephrine thiab norepinephrine.
Ua raws li qhov xav tau, inhibitory neurotransmitters ua dab tsi?
Inhibitory neurotransmitters muaj inhibitory cuam tshuam rau neuron. Qhov no txhais tau tias lawv txo qis qhov yuav ua rau lub neuron yuav tua hluav taws. Modulatory cov neurotransmitters tuaj yeem cuam tshuam ntau tus neurons tib lub sijhawm thiab cuam tshuam qhov cuam tshuam ntawm lwm cov neeg xa xov tshuaj.
Ib qho ntxiv, yuav muaj dab tsi tshwm sim rau cov neeg xa xov paj hlwb tom qab lawv tau siv lawm? Tom qab tso rau hauv lub synaptic cleft, cov neurotransmitters cuam tshuam nrog cov receptor cov protein ntawm daim nyias nyias ntawm cov cell postsynaptic, ua rau ionic raws ntawm daim nyias nyias los qhib lossis kaw. Thaum cov channel no qhib, depolarization tshwm sim , ua rau kev pib ntawm lwm qhov kev nqis tes ua.
Ntawm no, dab tsi yog excitatory thiab inhibitory?
Ib zoo siab heev neurons tau txhais tias yog neuron uas ua rau muaj kev hloov pauv zoo hauv daim nyias nyias ntawm cov post synaptic neuron nws txuas rau. Ib inhibitory neuron ua rau muaj kev hloov pauv tsis zoo hauv daim nyias nyias ntawm cov post synaptic neuron nws conencts rau.
Dab tsi yog qhov excitatory teb?
Ib zoo siab synapse yog synapse nyob rau hauv uas muaj peev xwm ua hauv presynaptic neuron nce qhov tshwm sim ntawm qhov muaj peev xwm ua tau tshwm sim hauv cell postsynaptic. Neurons tsim cov tes hauj lwm los ntawm cov hlab ntsha impulses mus ncig, txhua tus neuron feem ntau ua rau muaj kev sib txuas nrog lwm cov hlwb.

Dab tsi yog glycoprotein dab tsi yog ib qho ntawm kev siv glycoproteins?
Glycoproteins yog cov protein uas muaj cov oligosaccharide saw (glycans) covalently txuas nrog cov amino acid sab-saw. Glycoproteins kuj tseem yog ib qho tseem ceeb ua ke ntawm cov protein, uas lawv ua lub luag haujlwm hauv kev sib cuam tshuam ntawm tes -cell
Dab tsi yog cov khoom siv hauv lub cev zom zaub mov thiab lawv lub luag haujlwm yog dab tsi?
Cov khoom siv hauv lub cev zom zaub mov suav nrog cov hniav, tus nplaig, cov qog ua kua qaub, daim siab, lub zais zis, thiab txiav txiav. Txhawm rau ua tiav lub hom phiaj ntawm kev muab lub zog thiab khoom noj khoom haus rau lub cev, rau lub luag haujlwm tseem ceeb nyob hauv cov txheej txheem zom zaub mov: nqos. Kev zais
Kev sib txheeb ntawm cov neurotransmitters thiab kev nyuaj siab yog dab tsi?
Kev nyuaj siab tau txuas rau cov teeb meem lossis tsis sib xws hauv lub hlwb nrog rau kev xa cov neurotransmitters serotonin, norepinephrine, thiab dopamine. Cov pov thawj yog qee qhov tsis ncaj rau cov ntsiab lus no vim tias nws nyuaj heev los ntsuas qib kev xa xov paj hlwb hauv tib neeg lub hlwb
Dab tsi yog 4 lub ntsiab neurotransmitters?
Plaub qhov loj neurotransmitters uas tswj kev xav yog Serotonin, Dopamine, GABA thiab Norepinephrine. Thaum ua haujlwm kom raug, koj lub paj hlwb muaj kev tshuaj xyuas thiab sib npaug hauv daim ntawv ntawm kev txwv tsis pub muaj suab nrov (calming) thiab ua rau muaj kev cuam tshuam (txhawb nqa) cov paj hlwb
Dab tsi yog qhov cuam tshuam ntawm cov neurotransmitters?
Tus kws xa xov paj hlwb tau txhais tias yog tshuaj xa xov uas nqa, txhawb nqa, thiab ntsuas qhov sib npaug ntawm cov paj hlwb, lossis cov paj hlwb, thiab lwm lub hlwb hauv lub cev. Cov kws xa xov tshuaj tuaj yeem cuam tshuam ntau yam ntawm lub cev thiab lub paj hlwb suav nrog lub plawv dhia, pw tsaug zog, qab los noj mov, xav li cas, thiab ntshai
