Umxholo
Inkqubo ye- iiseli zemithambo-luvo Ziiseli zemithambo-luvo, oko kukuthi, ezo zibumba ingqondo kunye nayo yonke inkqubo yeemvakalelo. Ezi seli zinxibelelana zodwa izinto zemichiza igama iiurotransmitters. Bafunyanwa ngo-1921 ngu-Otto Loewi.
I-Neurotransmitters ingaba:
- Ii-amino acid: iimolekyuli eziphilayo eyenziwe liqela le-amino kunye neqela le-carboxyl.
- Iimonamines: Iimolekyuli ezivela kwiamino acid.
- Iipeptides: Iimolekyuli ezenziwa ngokudibana kwee-amino acid ezininzi, ngokusebenzisa iibhondi ezizodwa ezibizwa ngokuba ziipeptides.
Imizekelo yee-neurotransmitters
- Iasetylcholine: ivuselela izihlunu, ngokusebenzisa iimotor neurons, ezalisekisa imisebenzi yokuvuselela okanye yokuthintela. Ikwenza imisebenzi kwingqondo, kwiindawo ezinxulumene nokuqwalaselwa, ukuvuswa, ukufunda kunye nenkumbulo.
- Icholecystokinin: thatha inxaxheba Ummiselo wehomoni.
- Dopamine (monoamine): ulawulo iintshukumo zomzimba ngokuzithandela kwaye ikwalawula iimvakalelo ezimnandi. Izalisekisa imisebenzi yokuthintela.
- Enkephalins (I-neuropeptide): ukusebenza kwayo kuthintela, kunceda ukuthintela iintlungu.
- Endorphins (I-neuropeptide): inefuthe elifanayo nele-opiates: ukunciphisa iintlungu, uxinzelelo kunye nokunceda ukubuyisela ukuzola. Kwezinye izilwanyana, ziyabavumela ukuba basebusika, ngenxa yokuhla kwemetabolism, inqanaba lokuphefumla kunye nenqanaba lentliziyo.
- Epinephrine (i-monoamine): sisiphumo se-norepinephrine, sisebenza njengesonwabisa, silawula ukugxila kwengqondo kunye nokuqwalaselwa.
- GABA (I-Gamma Aminobutyric Acid) (i-amino acid): ukusebenza kwayo kuthintelo kuba kunciphisa ukusebenza kwe-neuronal kwaye ngale ndlela kuthintela ukutyeba kakhulu kwaye ngenxa yoko kunciphisa uxinzelelo.
- Glutamate (iamino acid): Umsebenzi wayo uyonwabisa. Inxulunyaniswa nemisebenzi yokufunda kunye nenkumbulo.
- Iwisteria (iamino acid): ukusebenza kwayo kuthintelwe kwaye kuyeyona ininzi kwintambo yomqolo.
- Imbali (i-monoamine): ikakhulu imisebenzi yovuyo, enxulunyaniswa neemvakalelo kunye nommiselo we ubushushu kunye nokulingana kwamanzi.
- Inorepinephrin (i-monoamine): umsebenzi wayo uyonwabisa, ulawula imood kunye nokuvuselela imvakalelo kunye nomzimba. Yandisa ukubetha kwentliziyo kunye noxinzelelo lwegazi.
- ISerotonin (I-monoamine): ukusebenza kwayo kuthintela, kungenelela kwiimvakalelo, imood kunye noxinzelelo. Ithatha inxaxheba kummiselo wokulala, ukuvuka kunye nokutya.
