Masifunde ngenkqubo "yokuphumla" yomzimba wethu? (Inkqubo yeNervous yeParasympathetic - PSNS)

Ngaba wakha wazibuza ukuba ezinye zezinto emzimbeni wakho - ukuphefumla, ukubetha kwentliziyo yakho, ukugaya kwakho - zilawulwa ngokuzenzekelayo, ngaphandle kokuba wena uqonde? Uninzi lwale misebenzi ibalulekileyo yenzeka ngaphakathi emizimbeni yethu ngaphandle kokuba sicinge ngayo. Isizathu soku kukuba imizimba yethu inenkqubo 'ezenzekelayo'. Namhlanje siza kuthetha ngenxalenye ebaluleke kakhulu yale nkqubo ezenzekelayo, leyo isizisela ukuphumla - oko kukuthi inkqubo ye-parasympathetic nervous , okanye njengoko oogqirha beyibiza (i-Parasympathetic Nervous System - PSNS) .

Yintoni le nkqubo ye-parasympathetic nervous system (PSNS)?

Ngamafutshane, inkqubo yakho ye-parasympathetic nervous system (PSNS) yinxalenye yenkqubo yakho ye-autonomic nervous system. Ingabizwa ngokuba yinkqubo ye-"automatic" nervous system, kuba inoxanduva lweenkqubo ezininzi ozilawulayo ngaphandle kokucinga ngazo. Umzekelo, ilawula isantya sentliziyo yakho, uxinzelelo lwegazi , ukugaya ukutya, ukuchama, kunye nokubila. Cinga ngayo, kukho enye inxalenye yenkqubo yakho ye-autonomic nervous system ebizwa ngokuba yi-sympathetic nervous system . Inoxanduva lokulungiselela umzimba wakho "ukulwa okanye ukubaleka." Oko kukuthi, isebenza ngamaxesha engozi okanye uloyiko. Nangona kunjalo, inkqubo ye-parasympathetic nervous system (PSNS) yahlukile ngokupheleleyo. Ilawula imisebenzi yomzimba wakho xa uphumle kwaye uzolile. Ezi zimbini zifana namacala amabini eengqekembe zemali, zincedana kwaye zigcina ibhalansi .

Kwenzeka ntoni kwinkqubo ye-parasympathetic nervous system (PSNS)?

Umsebenzi ophambili wale nkqubo kukuthomalalisa okanye ukucothisa ukusebenza komzimba wakho. Yiyo loo nto ibizwa ngokuba "yiphumle kwaye uyigaye" okanye "yitya kwaye uzale." La magama kulula ukuwakhumbula. Makhe sibone ukuba le nkqubo inaziphi iziphumo kwiindawo ezahlukeneyo zomzimba wethu:

• Amehlo: Khawuthelekelele ukuba ngequbuliso ungene kwindawo ekhanyayo aze amehlo akho abonakale eluhlaza okwesibhakabhaka, akunjalo? Ngelo xesha, le nkqubo yiyo ebangela ukuba umbala omnyama ongaphakathi kweliso lakho unciphe, oko kukuthi, unciphe, ukuze kuncitshiswe ukukhanya okungena emehlweni akho. Ikwatshintsha izinto ezikunceda ubone izinto ezikufutshane nawe ngokucacileyo, njengaxa ufunda incwadi okanye iphephandaba. Ikwabangela ukuba iinyembezi ziphume emehlweni akho, nto leyo ekhusela amehlo akho ekubeni ome.

• Impumlo nomlomo:Xa uphumle, amadlala emlonyeni wakho ayakhuthazwa ukuba avelise amathe amaninzi. Amadlala empumlweni yakho nawo anceda ekuveliseni amathe. La mathe kunye namathe abalulekile ekugayeni ukutya kwaye enze kube lula ukuphefumla ngexesha lokuphumla.

• Imiphunga: Xa uphumle, imiphunga yakho ayinyanzelekanga ukuba isebenze nzima kangako. Ngoko ke, izihlunu ezikwindlela yakho yomoya ziyaqina (zinciphe), nto leyo enciphisa umsebenzi ekufuneka wenziwe yimiphunga yakho.

• Intliziyo: Oku kubaluleke kakhulu. Kunciphisa isantya sentliziyo yakho, kwaye kunciphisa namandla ebetha ngawo intliziyo, amandla ahamba ngawo intliziyo epompa igazi. Yiyo loo nto intliziyo ibetha ngokukhawuleza xa silele kwaye siphumle.

• Indlela yokugaya: Le yeyona nto iphambili ekuthiwa "yiphumle kwaye ugaye." Xa usitya ukutya okunempilo, izinga lokugaya liyakhula kwaye amandla afunekayo ajoliswe kuloo ndawo. Ayipheleli apho, kodwa ipancreas yakho ikwaxelelwa ukuba yenze ihomoni ebizwa ngokuba yi-insulin ize iyikhuphe egazini. Le insulin isetyenziselwa ukuqhekeza iiswekile esizityayo kwaye izenze zifumaneke ukuze zisetyenziswe ziiseli zomzimba wethu.

• Ukususwa kwenkunkuma: Xa kufuneka uchame okanye ukhulule inkunkuma, le nkqubo ikhulula izihlunu ezilawulayo, iququzelele inkqubo.

• Inkqubo yokuzala: Le nkqubo ikwanceda ekulawuleni ezinye izinto ezibalulekileyo ezinxulumene nemisebenzi yesondo yomzimba. Umzekelo, ibandakanyeka kwizinto ezifana nokuqiniswa kwamadoda kunye nokukhutshwa kwezithambiso ngexesha lokwabelana ngesondo kwabasetyhini.

Yintoni umahluko phakathi kweenkqubo ze-nervous ze-Parasympathetic kunye ne-Sympathetic?

Njengoko besikhe sathetha ngaphambili, imisebenzi yale nkqubo mibini yemithambo-luvo iyaphikisana, kodwa zombini zibalulekile emizimbeni yethu, kungekhona njengeenkemba ezimbini ezibukhali kabini, kodwa njengabahlobo ababini abancedanayo. Cinga ngayo njengeNkqubo yeNervous enovelwano, efana "nomphathi wongxamiseko" womzimba wethu. Xa kukho ingozi, uloyiko, okanye isoyikiso, yinto eza kuqala. Yonyusa isantya sentliziyo, ikhulise amehlo, kwaye ikhawulezise ukuphefumla—zonke ezi zinto zenziwa ukusinika amandla okujongana naloo meko. Nangona kunjalo, ukuba le nkqubo isebenza ixesha elide kakhulu, inokudinisa umzimba kwaye ibeke uxinzelelo kwiinkqubo ezahlukeneyo. Kulapho ke iNkqubo yeNervous yeParasympathetic (PSNS) iqala khona ukusebenza.Iyanceda. Ikwenza oku ngokubuyisela iinkqubo zomzimba ezaziphazamisekile kwimeko yazo eqhelekileyo, kwimeko ezolileyo. Oko kukuthi, ngenxa yokuba ezi nkqubo zimbini zilawulana, umzimba wethu ugcina ibhalansi. Kwakhona, xa uzolile kwaye ukhuselekile, yinkqubo ye-parasympathetic (PSNS) elawula imisebenzi yamalungu omzimba wakho wonke. Nangona le misebenzi inganxulunyaniswanga nengozi okanye umngcipheko, ibalulekile ekukugcineni uphilile kwaye uphila.

Iphi inkqubo ye-parasympathetic nervous system (PSNS)?

Inkqubo ye-parasympathetic nervous (PSNS), njengoko besitshilo ngaphambili, yenye yeenxalenye ezimbini zenkqubo ye-autonomic nervous. Inkqubo yakho ye-autonomic nervous yinxalenye yenkqubo ye-peripheral nervous. Inkqubo ye-peripheral nervous yingqondo yakho kunye nomgogodla, kunye nazo zonke ezinye izicubu ze-nervous emzimbeni wakho. Okumangalisayo kukuba, inkqubo yakho ye-parasympathetic nervous (PSNS) isebenzisa ii-4 kwii-12 ze-cranial nerves zakho. Ezi nervous ze-cranial zii-nervous eziqhagamshela ngqo kwingqondo yakho. Ezintathu kwezi nervous zine ziqhagamshela kuphela kwiimvakalelo kunye nama-glands emehlweni akho, empumlweni, nasemlonyeni. Kodwa eyesine, i-vagus nerve , ikhethekile kakhulu. Iqhagamshela kwiindawo zomlomo wakho, kwaye iphinda ihambe entanyeni yakho, esifubeni sakho, nasesiswini sakho. Enyanisweni, i-Vagus Nerve yenza malunga ne-75% yenkqubo yakho yonke ye-parasympathetic nervous (PSNS). Iqhagamshela kwizitho ezininzi ezibalulekileyo zangaphakathi, njengentliziyo yakho kunye nemiphunga. Ukongeza, le nkqubo ikwasebenzisa ezinye ii-spinal nervous ezisezantsi komqolo wakho. Ezi zezo zithumela imiqondiso kwisinyi sakho nasemathunjini, ziphumze kwaye zikuncede uye kwigumbi lokuhlambela.

Yenziwe ngantoni le nto?
