Umthethonqubo we-Neurohumoral

Umsebenzi obalulekile kunoma yimuphi umuthi kufanele wenziwe ngokuhambisana nezimo ezizungezile. Ngenxa yalokhu, kubalulekile ukuqonda, ukulinganisa, ukucubungula kahle nokuphendula izibonakaliso ezivela ngaphandle. Kulesi simo, umzimba wonke kufanele usebenze njengeyunithi, izitho ezisebenza ngendlela ehlelekile futhi ehlelekile.

Ngokuhleleka nokuhambisana kwemisebenzi, uhlelo lwe-neurohumoral luphendula emzimbeni. Lithinta izinhlelo kanye nezitho ngokwahlukana, besebenzisa ukulawula phezu kwazo zonke izinqubo zomsebenzi obalulekile emzimbeni. Ngakho-ke, ubuqotho bemvelo bugcinwa.

Umthethonqubo we-Neurohumoral uwuhlobo lokulawula lapho izinto nezimo zesisindo ezithwala i-lymph negazi zihlanganisa inqubo eyodwa.

Umbuso osebenzayo wesimiso sezinzwa zomphakathi ungaphansi kwethonya lamakhemikhali asebenzayo ajikeleza egazini. Ngakho-ke, ngokwesibonelo, ukwakheka kwe-hormone ezigciniwe zangasese zangasese futhi kwasakazeka egazini kwenzeka ngaphansi kwethonya lokulawulwa kwesimiso sezinzwa.

Umthethonqubo we-Neurohumoral uyingxenye ebalulekile yenqubo yokugcina ukuhlala kwangaphakathi komzimba nokulinganisa nemvelo yangaphandle. Futhi unendima ebalulekile ezinkambisweni zokuzilinganisa izinto zomzimba (ukuzigcina ngokuzenzekelayo izinga lezinqubo kanye nezimo zomzimba emzimbeni). Umthethonqubo we-Neurohumoral uhlanganisa izindlela ze-humoral neural, ngaleyo ndlela unikeza indlela ephelele kakhulu yokulingana kunomunye wabo ngokwahlukana. Isixhumanisi esihlalisayo sithinta amathonya okulawula isikhathi eside. Ngesixhumanisi sezinzwa, ukuxhumana okusheshayo phakathi kwamasayithi ahlukene kunikeziwe.

Umthetho we-Neurohumoral wemisebenzi yomzimba wenziwa ngezindlela ezimbili. Indlela yokuqala ibhekisela ekusebenzeni okuqondile kwamahomoni noma imikhiqizo ye-metabolic ezinhlotsheni zesimiso sezinzwa zomphakathi. Lokhu kushintshela ukuzwakalisa amangqamuzana omzimba. Isibonelo, i-carbon dioxide egazini yenza ama cell cell ohlelweni lokuphefumula, futhi ukucasula kwamaseli wesistimu yokudla kwenziwa nge-chemical composition of the blood. Umthethonqubo we-Neurohumoral wenziwa futhi yisenzo sezinto ezihlukahlukene ezithathwe ngumzimba ngosizo lwegazi ezithombeni ezikhethekile zezitho zangaphakathi. Baqala ukusabela ekushintsheni ekwakhiweni kwamakhemikhali nokucindezela kwe-osmotic kweziphuzo. Ngakho-ke, isibonelo, kanye namaseli wesistimu yokuphefumula, i-chemoreceptors yezindonga ze-vascular isabela ekushintsheni kokuqukethwe kwe-carbon dioxide egazini.

Esikhathini somthethonqubo we-neurohumoral kuhileleke inani elikhulu lemikhiqizo yemetaboli ecacile neyiyo. Lezi zibandakanya ama-hormone amathumbu kanye nezicubu, i-histamine, i-hypothalamic neurohormones, i-oligopeptides ehlukahlukene, i-prostaglandins. Ngokugeleza kwegazi, zisakazeka kuwo wonke umzimba. Noma kunjalo, babangela ukusabela okuqondile kuphela "ezingxenyeni eziphumela" lapho bengena ekuxhumaneni nama-receptors abo.

Isimo sezinhlelo ze-nervous and humoral emzimbeni sinqunywa izinga lemikhiqizo esebenzayo ezikhungweni nasezikhungweni zamanzi. Ngesikhathi esifanayo, i-radioimmunoassay, i-immunocytochemistry, i-histochemistry, ukuhlaziywa kwe-ultrastructural isetshenziswa kabanzi. Ushintsho oluqhubekayo ebuhlotsheni obuningi nolulinganiselayo lwezinto eziphilayo ezisebenzayo lubonisa futhi lugcizelele ukusebenzisana kanye nezwi lazo zombili izingxenye eziphakathi nendawo zomhlaba ohlelweni lwezinzwa, futhi lusebenta umsebenzi obalulekile wenyama yonke. Ama-dynamics yenqubo yokulawula ixhomeke, ikakhulukazi, ekusebenziseni kwangaphandle nangokwezidingo zomzimba.
