Gated Channels Ib qho loj subset muaj nuj nqi raws li neurotransmitter receptors-lawv tshwm sim ntawm postsynaptic sites, thiab cov tshuaj ligand uas rooj vag lawv tso tawm los ntawm presynaptic axon davhlau ya nyob twg.
gated channel yog dab tsi?
(Science: physiology) transmembrane proteins ntawm excitable cells, uas tso cai rau cov flux ntawm ions kom dhau raws li qhov xwm txheej. Cov channel yuav yog qhov voltage gated, xws li sodium channel ntawm neurons lossis ligand gated xws li acetylcholine receptor ntawm cholinergic synapses.
Cov kab hluav taws xob hluav taws xob nyob qhov twg?
Feem ntau, voltage-gated sodium (Nav) thiab voltage-gated potassium (Kv1 thiab KCNQ) raws yog nyob rau hauv the axon, thiab Kv2, Kv4, thiab hyperpolarization- activated cyclic nucleotide-gated channels (HCNs) nyob rau hauv cov dendrites.
Cov channel nyob rau hauv lub neuron nyob qhov twg?
Nyob rau hauv cov neuron, tshuaj lom neeg gated ion channels yog tam sim no ntawm dendrites thiab cell lub cev. Raws li axon yog voltage-gated sodium ion thiab potassium ion channels. Voltage-gated calcium ion channels nyob ntawm axon terminals. Tag nrho cov gated channel raug kaw ntawm qhov chaw so membrane.
Ion channel nyob qhov twg?
Ion channel receptors feem ntau yog cov protein ntau nyob hauv hauv cov ntshav plasma. Txhua yam ntawm cov proteins no npaj nws tus kheej kom nws tsim txoj kev nkag los yog qhov pore nthuav tawm ntawm ib sab ntawm daim nyias nyias mus rau.lwm yam.

Nyob rau hauv ib lub neuron qhov twg voltage-gated calcium channel nyob?
Voltage-gated calcium channels (VGCCs), tseem hu ua voltage-dependent calcium channels (VDCCs), yog ib pab pawg ntawm voltage-gated ion channels pom nyob rau hauv daim nyias nyias ntawm cov hlwb excitable (xws li, cov leeg, glial hlwb, neurons, thiab lwm yam.
