Neurotransmitter tso tawm los ntawm presynaptic davhlau ya nyob twg muaj ib tug series ntawm intricate kauj ruam: 1) depolarization ntawm lub davhlau ya nyob twg daim nyias nyias, 2) activation ntawm voltage-gated Ca 2+ channels, 3) Ca2+ nkag, 4) kev hloov pauv ntawm kev sib hloov ntawm docking proteins, 5) fusion ntawm vesicle mus rau plasma membrane, nrog tom ntej …
Tus txheej txheem ntawm neurotransmission yog dab tsi?
Neurotransmission (Latin: transmissio "dhau, hla" los ntawm transmittere "xa, cia dhau") yog txheej txheem los ntawm kev taw qhia cov khoom hu ua neurotransmitters raug tso tawm los ntawm axon davhlau ya nyob twg ntawm neuron (lub presynaptic neuron), thiab khi rau thiab hnov mob nrog cov receptors ntawm dendrites ntawm lwm cov neuron (tus …
plaub kauj ruam ntawm kev sib kis neural yog dab tsi?
Synthesis thiab Cia; II. Tso tawm; III. Postynaptic Receptors; IV. Inactivation.
Tus txheej txheem ntawm neurotransmission pib qhov twg?
Neurotransmission nyob rau hauv lub paj hlwb yog pib ntawm presynaptic terminals los ntawm fusion ntawm synaptic vesicles nrog cov plasma membrane thiab tom qab exocytic tso tawm ntawm cov tshuaj transmitters. Muaj ntau txoj hauv kev los kuaj pom cov kab mob neurotransmitter tso tawm ntawm cov paj hlwb.
Dab tsi yog 6 kauj ruam ntawm kev sib kis ntawm synaptic?
1) ua ke hauv cov neuron, 2) khaws cia hauv cov paj hlwb, 3) tso tawm ntau txaus los cuam tshuam rau postsynaptic cell, 4) exogenous daim ntawv thov kev ua haujlwm, 5) mechanism rau tshem tawm, 6) muaj thiab siv cov tshuaj pharmacological blockers thiab agonists.
