Cov peev xwm ua tau feem ntau yog pib ntawm qhov pib qis " tsam cheeb tsam "uas yog qhov zoo siab tshaj li lwm qhov ntawm soma lossis dendrites. Qhov no tsam cheeb tsam yog nyob ntawm axon thawj ntu, axon hillock (uas muaj qhov siab tshaj plaws ntawm Na+-VWG).

Ib yam li ntawd, koj tuaj yeem nug, Chemoreceptor ua rau thaj chaw nyob qhov twg?

Cov chemoreceptor txhais thaj tsam ( CTZ ) yog thaj chaw ntawm medulla oblongata uas tau txais cov tswv yim los ntawm cov tshuaj muaj ntshav los yog cov tshuaj hormones, thiab sib txuas lus nrog lwm cov qauv hauv qhov chaw ntuav kom pib ntuav.

Ib qho ntxiv, dab tsi ntawm lub hlwb ua rau ntuav? medulla oblongata

Yog li ntawd, thaj tsam twg ntawm cov neuron hu ua thaj tsam ua rau?

Qhov kawg ntawm lub axon, lub axon terminus, yog thaj chaw zais cia uas tso cov neurotransmitters tso rau hauv lub synapse. Qhov ua rau thaj chaw yog thaj chaw uas muaj cov rooj tswj hwm tshuaj lom neeg thiab thaj chaw uas muaj lub zog tswj cov rooj vag sib ntsib, feem ntau nyob ntawm kev sib tshuam ntawm axon thiab lub cev ntawm tes, axon roob.

Dab tsi yog qhov ua haujlwm ntawm thaj tsam txhais?

Tus chemoreceptor tsam cheeb tsam yog thaj chaw ntawm medulla oblongata uas muaj ntau hom tshuaj lom neeg tuaj yeem ua rau xeev siab thiab ntuav.
