Signals taug kev raws lub axon ntawm ib tug neuron (uas peb yuav hu ua neuron A) nyob rau hauv daim ntawv ntawm an hluav taws xob impulse Thaum lawv ncav cuag lub paj hlwb xaus ntawm paj hlwb dawb endings tau ntsuas qhov kub thiab txias, txhua yam stimuli (kov, siab, ncab) lossis txaus ntshai (nociception)Yog li, cov paj hlwb sib txawv ua haujlwm raws li cov thermoreceptors, cutaneous mechanoreceptors thiab nociceptors. https://en.wikipedia.org › wiki › Free_nerve_ending

ntawm neuron Ib qho hluav taws xob impulse ua rau tso tawm cov tshuaj, hu ua neurotransmitters.
Nyob rau hauv daim ntawv twg yog cov teeb liab kis raws ib tug neuron?
Cov ntaub ntawv xa tawm raws li pob ntawv xov xwm hu ua ua haujlwm muaj peev xwm. Kev ua haujlwm muaj peev xwm taug kev hauv ib lub xov tooj ntawm tes raws li ib qho hluav taws xob hluav taws xob, tso cai rau lub net sab hauv ntws ntawm cov ions zoo rau hauv axon.
Yuav ua li cas cov teeb liab hla mus rau neurons?
Signal Transmission between Cells. Kev sib txuas lus ntawm cov neurons feem ntau tshwm sim nyob rau hauv cov kab mob microscopic hu ua synaptic clefts. … Ib tug neuron xa cov teeb liab (piv txwv li, presynaptic neuron) tso tawm tshuaj hu ua neurotransmitter, uas khi rau ib qho receptor ntawm qhov chaw txais (piv txwv li, postsynaptic) neuron.
neurons sib txuas lus li cas ib kauj ruam?
Cov kauj ruam hauv cov txheej txheem yooj yim:
- muaj peev xwm ua tau tsim nyob ze ntawm soma. Taug kev nrawm heev hauv axon. …
- vesicles fuse nrog pre-synaptic membrane. Thaum lawv fuse, lawv tso lawv cov ntsiab lus (neurotransmitters).
- Neurotransmitters ntws mus rau hauv lub synaptic cleft. …
- Tam sim no koj muaj cov kab mob neurotransmitter dawb hauv cov synaptic cleft.
Yuav ua li cas cov paib txav los ntawm lub paj hlwb mus rau lub hlwb?
Ib tug neuron lub axon yuav txuas tshuaj mus rau lwm tus neuron lub dendrite ntawm lub synapse ntawm lawv. … Nov yog cov saw tseem ceeb ntawm neural signal transmission, uas yog li cas lub paj hlwb xa cov cim rau cov leeg kom lawv txav mus, thiab seb lub cev puas siab puas ntsws xa cov cim rau lub hlwb.
