Hauv kev teb rau qhov muaj peev xwm nqis tes ua lossis qib peev xwm hluav taws xob, a neurotransmitter raug tso tawm ntawm presynaptic davhlau ya nyob twg Cov tso tawm neurotransmitter tom qab ntawd tuaj yeem hla hla lub synapse kom pom los ntawm thiab khi nrog cov neeg txais khoom hauv lub paj hlwb tom qab.
Kuj paub, yuav muaj dab tsi tshwm sim thaum lub tshuab xa xov paj tawm los ntawm presynaptic cell quizlet?
Ntawm cov tshuaj synapses, neurotransmitter molecules yog tso tawm los ntawm presynaptic neuron thiab khi rau kev sib raug zoo sib txuas raws ntawm postsynaptic ntawm tes daim nyias nyias. Kev qhib ntawm cov channel no tso cai rau ions nthuav tawm thoob plaws daim nyias nyias, ua rau muaj peev xwm ua tau zoo hauv kev ua haujlwm postsynaptic ntawm tes.
Ib tus kuj tseem yuav nug tau, dab tsi yog qhov xa tawm cov tshuaj xa xov rau? Molecules ntawm cov neurotransmitters tau khaws cia hauv "pob" me me hu ua vesicles (saib daim duab ntawm sab xis). Neurotransmitters yog tso tawm los ntawm axon davhlau ya nyob twg thaum lawv cov vesicles "fuse" nrog daim nyias nyias ntawm lub dav hlau axon, nchuav cov neurotransmitter mus rau hauv synaptic cleft.
Ib tus kuj tseem yuav nug tau, ua li cas tus xa xov paj tawm los ntawm presynaptic neuron?
Neurotransmitters yog tso tawm los ntawm synaptic vesicles hauv presynaptic neurons hauv kev teb rau kev ua haujlwm neural, nthuav dav hla qhov sib cais sib cais, thiab khi cov neeg txais tshwj xeeb txhawm rau coj los hloov pauv hauv postsynaptic cov neurons.
Cov tshuaj twg raug tso tawm hauv lub synapse?
neurotransmitter molecules

Dab tsi yog qhov teeb meem ntawm daim tawv nqaij uas tshwm sim los ntawm kev mob ntev ntawm cov qog sebaceous tshwm sim los ntawm cov khoom zais cia?
AKA pob txuv vulgaris- Cov teeb meem ntawm daim tawv nqaij ua rau mob ntev ntawm cov qog sebaceous los ntawm khaws cia tso zis thiab Propionbacterium acnes, lub sijhawm tshawb fawb rau cov kab mob pob txuv. Qhov mob ntawm daim tawv nqaij qhuav, tawv nqaij vim tsis muaj lossis tsis muaj sebum uas tshwm sim los ntawm cov laus thiab los ntawm qhov txias
Lub sijhawm tshem tawm cov khoom siv txawv teb chaws thiab tuag los yog cov ntaub so ntswg kis los ntawm tus kab mob los yog raug mob kom txog thaum cov nqaij mos noj qab nyob zoo raug nthuav tawm?
Kev debridement. tshem tawm cov khoom txawv teb chaws thiab cov ntaub so ntswg tuag los yog kab mob los ntawm thiab kis kab mob los yog raug mob mus txog rau thaum ib puag ncig cov ntaub so ntswg raug nthuav tawm. dermabrasion. ib lo lus uas txhais tau hais tias lub cev sanding ntawm daim tawv nqaij kom tshem tawm tattoos thiab nti kuj hu ua puas. daim tawv nqaij
Thaum tus kws kho mob tau tso cai tso cai ntau npaum li cas yuav tsum muaj kev sib ntsib tim ntsej tim muag tshwm sim ntawm tus kws kho mob thiab cov kws kho mob qib siab uas tau sau npe rau tus nais maum?
Txawm li cas los xij, yog tias APRN lossis PA tau nyob hauv daim ntawv pom zoo tso cai nrog kws saib xyuas kws kho mob tsawg kawg tsib ntawm xya xyoo dhau los, cov rooj sib tham tim ntsej tim muag yuav tsum tshwm sim tsawg kawg ib hlis txog rau thawj hnub ntawm hnub uas tau pom zoo kos npe
Yuav muaj dab tsi tshwm sim thaum cov thyroid tso tawm calcitonin?
Calcitonin raug tso tawm los ntawm cov thyroid caj pas yog tias cov calcium hauv cov hlab ntsha siab. Calcitonin txo qis cov calcium thiab phosphorus hauv cov ntshav. Nws ua qhov no los ntawm kev ua haujlwm qeeb ntawm cov cell pom hauv pob txha, hu ua osteoclasts. Cov hlwb no ua rau calcium tso tawm thaum lawv 'huv' pob txha
Cov tshuaj hormones twg raug tso tawm raws li qhov tshwm sim ncaj qha ntawm kev xav lub cev muaj zog neuron stimulation?
Feem ntau sympathetic postganglionic fibers tso norepinephrine. Raws li tau hais yav tas los, cov hlwb ntawm adrenal medulla raug txiav txim siab hloov pauv kev mob siab rau postganglionic neurons. Hloov chaw ntawm neurotransmitter, cov hlwb no tso cov tshuaj hormones rau hauv cov ntshav
