tso tawm cov tshuaj neuroactive los ntawm exocytosis los ntawm dendrites yog qhov nthuav dav heev thiab tsis nyob rau hauv ib chav kawm ntawm cov khoom xa tawm: nws tshwm sim hauv ntau lub paj hlwb, thiab suav nrog ntau yam ntawm neuropeptides, classical neurotransmitters thiab taw qhia cov khoom xws li nitric oxide., carbon monoxide, ATP …
Ntaus neurotransmitters secreted los ntawm?
Molecules ntawm neurotransmitters yog khaws cia hauv me "pob" hu ua vesicles (saib daim duab ntawm sab xis). Neurotransmitters raug tso tawm los ntawm lub axon davhlau ya nyob twgthaum lawv vesicles "fuse" nrog rau daim nyias nyias ntawm lub axon davhlau ya nyob twg, spilling lub neurotransmitter mus rau hauv lub synaptic cleft.
Dendrites puas tau tso cov neurotransmitters?
Dendrites yog cov ntawv ntxiv uas tsim los kom tau txais kev sib txuas lus los ntawm lwm lub hlwb. … Txawm hais tias dendrites ib txwm raug suav hais tias yog cov neeg txais cov neurotransmission, kev tshawb fawb tsis ntev los no tau pom tias dendrites tuaj yeem tso cov neurotransmitters rau hauv synapse (Stuart et al., 2008).
Pob dendrites lossis axons tso cov neurotransmitters?
Axon - Cov qauv ntev, nyias nyias uas muaj peev xwm ua tau raug tsim; qhov kis ntawm cov neuron. Tom qab pib, qhov kev ua tau zoo taug kev mus rau axons kom tso tawm cov neurotransmitter. Dendrite - Qhov tau txais ib feem ntawm cov neuron.
Dab tsi secretes neurotransmittersnyob rau hauv ib tug neuron?
Neurotransmitters khaws cia hauv synaptic vesicles, clustered ze rau cell membrane ntawm axon davhlau ya nyob twg ntawm presynaptic neuron. Neurotransmitters raug tso tawm rau hauv thiab nthuav dav thoob plaws lub synaptic cleft, qhov twg lawv khi rau cov receptors tshwj xeeb ntawm daim nyias nyias ntawm postsynaptic neuron.
