'Isilumkiso' somzimba sokukusindisa ngexesha loxinzelelo: Masifunde nje nge-Adrenal Medulla!

Khawuthelekelele uhamba esitalatweni uze ngequbuliso inja itsibe phezulu. Okanye uza kuthatha uvavanyo olubalulekileyo. Isantya sentliziyo yakho siyanda ngequbuliso, uyabila, amehlo akho avuleke, kwaye umzimba wakho wonke ukhawuleza uphapheme, akunjalo? Inxalenye encinci kodwa enamandla kakhulu yomzimba wakho ikulungiselela ngoko nangoko imeko engxamisekileyo okanye uxinzelelo. Namhlanje sithetha 'ngeziko lokuphendula ngokukhawuleza' emzimbeni wethu, i-Adrenal Medulla.

Yintoni iAdrenal Medulla? Iphi?

Ngamafutshane, i-Adrenal Medulla yeyona ndawo ingaphakathi yee-Adrenal Glands emzimbeni wethu. Njengomngxuma wemango, i-Medulla yimbindi yangaphakathi ye-Adrenal Gland. Ii-Adrenal Glands zii-glands ezimbini ezincinci ezihlala phezu kwezintso zethu, njengee-hat ezimbini.

I-adrenal gland yahlulwe yangamacandelo amabini aphambili:

1. I-Adrenal Cortex: Le yeyona nxalenye inkulu ye-gland, efumaneka ngaphandle.

2. I-Adrenal Medulla: Le yinxalenye encinci ngaphakathi kwe-gland esithetha ngayo namhlanje.

Ezi nxalenye zimbini zivelisa iintlobo ezahlukeneyo zeehomoni. I-adrenal medulla ikakhulu ivelisa iihomoni ezilawula inkqubo yethu ye-autonomic nervous. Inkqubo ye-autonomic nervous yinkqubo elawula izinto esingazilawuli ngabom, ezifana nokubetha kwentliziyo, ukuphefumla, kunye nokubila. Ngoko ke indima ye-adrenal medulla ibaluleke kakhulu.

Yintoni enkulu eyenzeka kule nxalenye incinci?

Umsebenzi ophambili we-Adrenal Medulla kukusabela kuxinzelelo . Oko kukuthi, ukulungiselela imizimba yethu ukuba ijongane nemeko eyingozi okanye engxamisekileyo. Oku sikubiza ngokuba yimpendulo ethi 'Yilwa okanye Ubhabha' . NgesiSinhala, kuthetha "impendulo yokulwa okanye ukubhabha".

Khawucinge nje ukuba ubuhamba wedwa esitalatweni ebusuku uze uzive ngathi kukho umntu okulandelayo, bekuya kwenzeka ntoni emzimbeni wakho?

• Isantya sentliziyo sinyuka ngequbuliso.
• Izinga lokuphefumla liyanyuka.
• Iimbombo zamehlo ziyakhula kwaye umbono uba bukhali ngakumbi.
• Igazi elingakumbi lihamba liye kwimisipha yamalungu, liwanika amandla afunekayo ukuze abaleke okanye alwe.
• Imvakalelo yentlungu iyancipha okwethutyana.

Konke oku kwenzeka kwimizuzwana embalwa ngenxa yeqela leehomoni ezibizwa ngokuba zii-catecholamines, ezikhutshwa yi-adrenal medulla. Ezi zezona zinto zivuselela 'isilumkiso esingxamisekileyo' somzimba wethu.

Kukho iintlobo ezimbini eziphambili ze-catecholamines:

1. I-Adrenaline - Elinye igama lale nto yi -Epinephrine .

2. I-Noradrenaline - Elinye igama lale nto yiNorepinephrine .

Makhe sijonge ngokusondeleyo umsebenzi wezi hormone zimbini.

Yintoni isakhiwo se-Adrenal Medulla?

Eli lungu lincinci linesakhiwo esikhethekileyo sokwenza umsebenzi walo ngokufanelekileyo.

• Ukunikezelwa kwegazi: I-adrenal medulla inokunikezelwa kwegazi okuninzi kakhulu. Oku kungenxa yokuba iihomoni ezikhutshwayo ngexesha likaxakeka kufuneka zithunyelwe emzimbeni wonke ngokukhawuleza. Ifumana igazi kumasebe avela kwimithambo yegazi emikhulu efana ne-abdominal aorta.
• Ukunikezelwa kwemithambo-luvo: I-medulla ifumana imiqondiso evela kwi-greater splanchnic nerve, eyinxalenye yenkqubo yethu ye-autonomic nervous. Xa ingqondo ifumana imiqondiso ethi "Ingozi, thatha inyathelo ngoku!", i-medulla ivuselelwa yile nerve.
• Iiseli zeChromaffin: Ezi zezona ntlobo zeeseli ezikhethekileyo kwi-adrenal medulla. Ezi seli ziqulathe iigranules ezincinci ezizaliswe ziihomoni i-adrenaline kunye ne-noradrenaline. Xa kufika isignali yemithambo-luvo, ezi seli zikhupha iipakethi zazo zeehomoni ngqo egazini.

Ziziphi iingxaki ezinokwenzeka kwi-Adrenal Medulla?

Izifo ze-adrenal medulla azixhaphakanga kakhulu , kodwa zinokuba yingozi ebomini ukuba ziyavela. Uninzi lwezi ngxaki zibangelwa ziithumba ezikhula kwi-medulla. Uninzi lwezi thumba azinamhlaza (azinabungozi). Ngamanye amaxesha zinokuzuzwa njengelifa.

Nazi ezinye zezona ntlobo ziphambili zamaqhuqhuva anokubonwa.

Zithini iimpawu zolu hlobo lwengxaki?

Uninzi lwezi thumba zikhula kancinci kakhulu, ngoko ke zisenokungabangeli zimpawu kwasekuqaleni. Ngamanye amaxesha, zifunyanwa ngengozi ngexesha le-CT okanye i-MRI scan ukuze kufunyanwe enye imeko (i-adrenal incidenticaloma) .

Nangona kunjalo, xa ithumba liqala ukukhupha iihomoni ezininzi kakhulu, iimpawu zinokuvela.Kumntu oneqhubu elinje, impendulo yomzimba nokuba uxinezelekile nje inokubaxwa. Ngamanye amaxesha, nokuba yinto elula njengokugoba phambili okanye ukutya ukutya okuthile kunokubangela iimpawu eziyingozi. Le meko siyibiza ngokuba yingxaki yoxinzelelo lwegazi .

Iimpawu ezinokwenzeka kwimeko enjalo yengxaki zezi:

• Intloko ebuhlungu kakhulu
• Iintlungu zesifuba
• Ukubila okugqithisileyo (hyperhidrosis)
• Ubunzima bokuphefumla (ukuphelelwa ngamandla)
• Isicaphucaphu nokuhlanza
• Ukubetha kwentliziyo
• Ukulahlekelwa yingqondo (i-syncope)
• Ukuxhuzula

Ukuba iimpawu ezinje zivele ngequbuliso, kubalulekile ukuya kwiYunithi yoNyango oluNgxamisekileyo (ETU) yesibhedlele ngoko nangoko .

Ezinye izifo ezinokubangelwa kukungalingani kwamahomoni

Iihormone ezikhutshwa yi-adrenal medulla (ingakumbi i-noradrenaline) zinxulumene kakhulu neemvakalelo zethu kunye nempilo yengqondo. Amanqanaba aphezulu ngokungaqhelekanga ezi hormones kwixesha elide anokubangela iingxaki zempilo yengqondo.

Nazi ezinye zeemeko ezinjalo:

• Ixhala
• Uxinzelelo
• Ingxaki yovalo
• Ingxaki yokungakwazi ukunikel’ ingqalelo (ADHD)
• Ingxaki yoxinzelelo emva kwengozi (PTSD)
• Umlutha

Oku akuthethi ukuba zonke ezi zifo zibangelwa yingxaki ye-adrenal medulla. Nangona kunjalo, ukungalingani kwezi hormones kunokubangela okanye kuzenze zibe mandundu ezi mpawu.

Ziziphi iindlela zonyango zezi meko?

Iindlela zonyango zixhomekeke ekuxilongweni kwakho kunye nobunzima beempawu zakho. Ugqirha wakho uza kukuhlola aze akucebise unyango olufanelekileyo.

• Unyango lweNgxaki yeHypertensive: Ekubeni le yingxamiseko, unyango lunikezelwa esibhedlele ukuze kwehliswe uxinzelelo lwegazi ngokukhawuleza. Ngenxa yoku, amayeza anjenge -vasodilators (amayeza andisa imithambo yegazi) anikwa ngemithambo yegazi.
• Unyango lweethumba kunye nomhlaza: Uninzi lweethumba lufuna ukususwa ngotyando. Ngamanye amaxesha elinye okanye omabini amadlala e-adrenal kunokufuneka asuswe. Ukuba ithumba linomhlaza, unyango olufana ne -radiation okanye i-chemotherapy nalo lunokufuneka.

Yintoni esifanele siyenze ukuze sigcine i-Adrenal Medulla isempilweni?

Ukugcina umzimba wethu uphela usempilweni kuyingenelo ekusebenzeni kwazo zonke izitho zomzimba, kuquka ne-Adrenal Medulla. Ngokukodwa, uxinzelelo olungapheliyo lunokusebenza kakhulu kule nkqubo kwaye lubangele ukudinwa. Kungoko ke, kubaluleke kakhulu ukunyamekela ezi zinto.

• Indlela yokuphila esebenzayo: Ukuzilolonga rhoqo kunceda kakhulu ekulawuleni uxinezeleko.
• Ukutya okunesondlo: Yitya ukutya okunesondlo okunemifuno, iziqhamo kunye neenkozo ezinesondlo.
• Ukusela amanzi aneleyo: Amanzi abalulekile kuyo yonke imisebenzi yomzimba.
• Ukulawula uxinzelelo: Zolisa ingqondo yakho ngokuzilolonga ngokuphefumla nzulu, ukucamngca, kunye nokwenza into oyithandayo.
• Unyango Lokuthintela: Yiya kuhlolo lwezonyango rhoqo kwaye ukhathalele impilo yakho yomzimba.

Ukuba unamathandabuzo okanye uxhalabile malunga neempawu ezikhankanyiweyo kweli nqaku, nceda udibane nogqirha wakho nixoxe ngazo . Ingcali ye-endocrinologist, ngokukodwa, iya kukunika ulwalathiso oluchanekileyo.
