Synaptic kis tau tus mob yog txheej txheem uas ib tus neuron sib txuas lus nrog lwm tus. Cov ntaub ntawv tau dhau los ntawm axon ntawm neuron raws li hluav taws xob impulse hu ua kev ua tau zoo. Thaum lub zog hluav taws xob (qhov muaj peev xwm ua tau) mus txog qhov no synaptic vesicles, lawv tso lawv cov ntsiab lus ntawm cov kab mob neurotransmitters.
Ua li no, lub hom phiaj ntawm kev sib kis ntawm synaptic yog dab tsi?
Synaptic kis tau tus mob yog txheej txheem uas ib lub neuron (cov xovtooj ntawm tes) sib txuas lus nrog lwm tus neurons lossis cov teebmeem, xws li cov leeg nqaij, ntawm a synapse . Ntawm synaptic pob qhov rooj, lub peev xwm ua tau hloov mus rau hauv cov lus tshuaj uas, dhau los, cuam tshuam nrog tus neeg txais neuron lossis effector.
Tsis tas li ntawd, vim li cas lub synapse tseem ceeb? Synapses yog cov junctions ntawm neurons nyob rau hauv lub paj hlwb. Ib qho tshuaj neurotransmitter raug tso tawm rau ntawd - tshuaj uas tso cai rau ib tus neuron tham nrog tus neuron tom ntej thiab txuas ntxiv xa qhov kev xav. Vim li cas lawv tseem ceeb ? Lawv xyuas kom meej tias qhov ntws ntawm impulses yog nyob rau hauv ib qho kev taw qhia nkaus xwb.
Khaws qhov no saib, dab tsi yog txheej txheem ntawm kev xa xov neural?
Neural kis tau tus mob tshwm sim thaum a neuron tau qhib, lossis raug rho tawm (xa tawm hluav taws xob). Thaum a neuron yog txaus stimulated mus txog rau neural qhov pib (ib theem ntawm stimulation hauv qab uas lub cell tsis tua), depolarization, los yog ib tug hloov nyob rau hauv cell muaj peev xwm, tshwm sim. Muaj peev xwm.
Synapse piav qhia yog dab tsi?
Synapse , tseem hu ua neuronal junction, qhov chaw ntawm kev sib kis ntawm hluav taws xob paj hlwb impulses ntawm ob lub paj hlwb (neurons) los yog ntawm ib tug neuron thiab ib caj pas los yog nqaij cell (effector). Kev sib txuas sib txuas ntawm cov neuron thiab cov leeg nqaij yog hu ua neuromuscular hlws ris.

Yuav muaj dab tsi tshwm sim yog tias ob qho tshuaj ntsuab tsis sib xws sib xyaw ua ke thiab thov?
Qhov ua tau los ntawm kev sib xyaw cov tshuaj tsis sib xws muaj ntau thiab suav nrog: * Txo qhov ua tau zoo ntawm ib lossis ob qhov sib xyaw * Ua kom cov dej nyob hauv lub tank, txhaws cov ntxaij vab tshaus thiab lub taub hau hauv lub tshuab txau * Tsob nroj phytotoxicity, ua kom qis lossis txo cov noob qoob loo * Ntau dhau lawm * Muaj dej ntau dhau
Yuav muaj dab tsi tshwm sim thaum cov leeg ncig sib cog lus?
Hauv lub teeb ci, cov leeg ncig ua haujlwm sib cog lus thaum cov leeg radial so. Qhov no ua rau tus menyuam kawm ntawv nruj thiab tsis pom lub teeb nkag mus rau qhov muag. Hauv qhov xwm txheej tsis zoo, qhov rov tshwm sim. Cov leeg ncig tau so thiab cov leeg sib zog ua haujlwm sib cog lus, ua rau cov menyuam kawm ntawv nthuav dav thiab tso lub teeb ntau dhau mus rau hauv lub qhov muag
Dab tsi tshwm sim tshwm sim ntawm kev sib tshuam neuromuscular?
Thaum qhov muaj peev xwm ua tau mus txog qhov sib txuas neuromuscular, nws ua rau acetylcholine raug tso tawm rau hauv qhov kev sib txuas no. Cov acetylcholine khi rau cov nicotinic receptors concentrated nyob rau hauv lub motor kawg phaj, ib qho chaw tshwj xeeb ntawm cov nqaij fibers lub post-synaptic membrane
Dab tsi tshwm sim tshwm sim ntawm kev sib tshuam neuromuscular uas ua rau cov leeg sib cog lus?

Cov kab mob sib kis tshwm sim tam sim no yog dab tsi?
Cov kab mob tshwm sim muaj xws li kab mob HIV, SARS, kab mob Lyme, Escherichia coli O157: H7 (E. coli), hantavirus, ua npaws kub, mob West Nile, thiab Zika virus. Cov kab mob rov nco tau yog cov kab mob uas rov tshwm sim dua tom qab lawv tau poob qis
