Structure thiab Function of Skeletal Muscle Lub postsynaptic membrane muaj tshwj xeeb ACh receptors (AChR), concentrated opposite thaj chaw nquag. Cov no yog ib qho zoo tshaj plaws-tus cwj pwm ionic channel. Lawv qhov qhib tso cai rau ions ntws raws li kev khi tshwj xeeb ntawm ACh.
Yuav ua li cas yog lub luag haujlwm ntawm postsynaptic membrane?
Nyob rau hauv cov tshuaj synapse, lub postsynaptic membrane yog membrane uas tau txais lub teeb liab (binds neurotransmitter) los ntawm presynaptic cell thiab teb los ntawm depolarisation los yog hyperpolarisation.
Vim li cas khi rau ntawm daim nyias nyias tseem ceeb?
Kev khi ntawm cov neurotransmitters, ncaj qha lossis tsis ncaj, ua rau cov ion channel hauv cov ntaub ntawv postsynaptic qhib lossis kaw(Daim duab 7.1). Feem ntau, qhov tshwm sim ion fluxes hloov pauv lub peev xwm ntawm daim nyias nyias ntawm lub cell postsynaptic, yog li kho cov kev hloov pauv ntawm cov ntaub ntawv hla lub synapse.
Vim li cas postsynaptic muaj peev xwm tseem ceeb?
Postsynaptic peev xwm (PSP), hloov pauv ib ntus hauv hluav taws xob polarization ntawm daim nyias nyias ntawm cov paj hlwb (neuron). … Lub peev xwm los koom ua ke ntau PSPs ntawm ntau lub synapses yog cov cuab yeej tseem ceeb ntawm cov neurons thiab hu ua summation.
Dab tsi yog qhov cuam tshuam rau ntawm lub cell postsynaptic?
Cov postsynaptic tam sim no tsim los ntawm synchronous qhib thiab kaw ntawm ion channels hloov cov membrane muaj peev xwm ntawm postsynaptic cellCov kev hloov pauv hauv qhov muaj peev xwm ua rau muaj qhov tshwm sim ntawm kev tua cov peev txheej yog excitatory, whereas cov uas txo qhov tshwm sim no yog inhibitory.

Vim li cas cov ntaub ntawv tseem ceeb tseem ceeb rau kev tswj hwm tebchaws Askiv?
Cov ntaub ntawv raug cai ntawm cov thawj coj hauv tebchaws Askiv ua haujlwm qhov tseem ceeb ntawm keeb kwm ntawm no lub sijhawm. Cov thawj coj hauv tebchaws Askiv ntseeg tias txhua qhov kev qhia, kev npaj, txoj cai, kev txiav txim siab, kev pom zoo, kev tshawb nrhiav yuav tsum tau sau kom meej.
Puas yog kab mob qhua pias thiab kab mob qhua pias los ntawm tib tus kab mob no?
Ntxhais kab mob yog kab mob kab mob ntawm daim tawv nqaijtshwm sim los ntawm tus kab mob cowpox lossis kab mob catpox. Qhov no yog ib tug tswv cuab ntawm tsev neeg Orthopoxvirus, uas suav nrog tus kab mob variola uas ua rau cov kab mob me. Cowpox zoo ib yam li tab sis mob me dua li kis tau zoo heev thiab qee zaum ua rau tus kab mob me me tuag taus .
Vim li cas cov cim tseem ceeb tseem ceeb?
Background. Cov cim tseem ceeb yog qhov tseem ceeb cov ntsiab lus ntawm kev saib xyuas tus neeg laus lossis tus menyuam qhov kev vam meej thaum mus pw hauv tsev kho mob, vim lawv tso cai rau kev tshawb pom sai ntawm kev rov qab los qeeb lossis cov xwm txheej tsis zoo.
Puas yog tus kab mob plague yog tus kab mob lossis kab mob?
Kab mob plague yog tshwm sim los ntawm cov kab mob Yersinia pestis, cov kab mob zoonotic feem ntau pom hauv cov tsiaj me thiab lawv cov dev. Cov neeg kis tus kab mob Y. pestis feem ntau tshwm sim tom qab lub sij hawm incubation ntawm ib mus rau xya hnub.
