Pre-propeptides yog synthesized nyob rau hauv qhov ntxhib endoplasmic reticulum, qhov twg lub teeb liab sib law liag ntawm cov amino acids-uas yog, cov ntu uas qhia tias peptide yog yuav tsum tau secreted-yog tshem tawm.
Hais txog qhov no, qhov twg yog cov neurotransmitters ua?
Neurotransmitters yog ua Nyob rau hauv lub cell lub cev ntawm lub neuron thiab ces thauj mus rau hauv lub axon mus rau lub axon davhlau ya nyob twg. Molecules ntawm cov neurotransmitters yog khaws cia rau hauv me me "pob" hu ua vesicles (saib daim duab ntawm sab xis).
Ib yam nkaus, qhov twg yog acetylcholine sib xyaw? Acetylcholine yog synthesized hauv qee qhov neurons los ntawm enzyme choline acetyltransferase los ntawm cov sib xyaw choline thiab acetyl-CoA. Cholinergic neurons muaj peev xwm ua tau ACh. Ib qho piv txwv ntawm thaj chaw hauv nruab nrab cholinergic yog lub nucleus basalis ntawm Meynert nyob rau hauv basal forebrain.
Tsuas yog li ntawd, qhov twg cov neurotransmitters synthesized thiab khaws cia?
Neurotransmitters yog synthesized los ntawm neurons thiab yog khaws cia hauv vesicles, uas ib txwm muaj nyob hauv axon lub davhlau ya nyob twg kawg, tseem hu ua presynaptic davhlau ya nyob twg. Lub davhlau ya nyob twg presynaptic tau sib cais los ntawm cov neuron lossis cov leeg lossis cov qog ntshav ntawm lub cev uas nws cuam tshuam los ntawm qhov sib txawv hu ua synaptic cleft.
Dab tsi yog 7 lub neurotransmitters loj?
Cov ntsiab lus hauv txheej no (7)
- acetylcholine tshuaj. Lub tshuab xa hluav taws xob siv los ntawm cov paj hlwb hauv PNS thiab CNS hauv kev tswj hwm kev ua haujlwm xws li cov leeg sib zog thiab lub plawv dhia mus rau kev zom thiab nco.
- norepinephrine.
- tshuaj serotonin.
- dopamine.
- GABA.
- glutamate.
- endorphin.
