Masifunde ngeqhawe elincinci elisebuchotsheni bethu: i-Posterior Pituitary Gland!

Umzimba wethu ufana nomatshini omangalisayo nontsonkothileyo, akunjalo? Sonke siyazi ukuba yonke into ekulo matshini ilawulwa yingqondo yethu. Kodwa ubusazi na ukuba ngaphakathi kwengqondo yakho, kukho idlala elincinci njengethambo elincinci, elikhupha iihomoni ezibalulekileyo ezilawula ubungakanani bamanzi emzimbeni wakho, libangele ukuba isibeleko sinciphe ngexesha lokubeleka, kwaye lenze olo lwalamano lumangalisayo phakathi komama nomntwana? Yiloo nto siza kuthetha ngayo namhlanje. Siyibiza ngokuba yiPituitary Gland. Namhlanje, siza kuthetha ngokweenkcukacha ngenxalenye ekhethekileyo yalo, iPosterior Pituitary.

Okokuqala, masibone, yintoni i-pituitary gland?

Khawuthelekelele ukuba umzimba wakho yinkampani enkulu. Emva koko i-CEO yaloo nkampani yinxalenye yobuchopho ebizwa ngokuba yi-hypothalamus. Ngaphantsi kwale CEO kukho umphathi jikelele. Loo nto yi-pituitary gland. Lo mphathi ubaluleke kakhulu, kuba ulawula ukusebenza kwezinye ii-glands ezininzi emzimbeni.

Le gland yepituitary ikwindawo ekhuselekileyo phantsi kwengqondo yakho, ngasemva kwempumlo yakho. Yahlulwe yangamacandelo amabini. Njengedesika yokwamkela iindwendwe eofisini kunye neofisi engasemva.

1. I-Anterior Pituitary: Le yeyona ndawo inkulu nexakekileyo. Ivelisa kwaye ikhuphe iihomoni ezininzi ezinxulumene nokukhula komzimba, umsebenzi we-thyroid, kunye nomsebenzi wesondo.

2. I-Posterior Pituitary: Lo ngumlinganiswa wethu ophambili. Incinci kune-anterior pituitary. Ayivelisi iihomoni, kodwa igcina iihomoni ezimbini ezikhethekileyo eziveliswayo nezithunyelwa yi-hypothalamus, kwaye izikhuphe egazini xa kufuneka.

Inkqubo equka zonke ii-glands ezivelisa iihomoni, kuquka ne-pituitary gland, ibizwa ngokuba yi-endocrine system . Le yinethiwekhi etshintshiselana imiyalezo yeekhemikhali emzimbeni.

Ngoko ke zeziphi ezo hormone zimbini ezikhethekileyo ezikhutshwa yiPosterior Pituitary?

Njengoko besitshilo ngaphambili, iPosterior Pituitary ifana nendawo yokugcina izinto. Kukho "izinto" ezimbini ezixabisekileyo ezigcinwe apha. Ziihormone ezimbini. Zombini ezi zenziwa yiHypothalamus. Xa umyalezo uvela apho ngemithambo-luvo, iPosterior Pituitary ikhupha ezi hormone egazini.

Nantsi ingcaciso elula yezi hormone zimbini kunye nomsebenzi wazo.

Khawucinge ngexesha apho ubila kakhulu kwaye unxaniwe. Ngelo xesha, igazi lakho liyaqina kancinci. I-hypothalamus esebuchotsheni iyakuqonda oku kwaye ithumela umyalezo kwi-Posterior Pituitary, ithi, "Kulungile, ngoku faka i-ADH egazini." Emva koko i-ADH iyahamba iye kuxelela izintso, "Sebenzisa amanzi kancinci, ungenzi umchamo omninzi." Kulapho ubungakanani bomchamo owudlulayo buncipha khona, kwaye umbala wawo uba mnyama. Xa umanzi ngokwaneleyo, kwenzeka okwahlukileyo. Amanqanaba e-ADH ayancipha, kwaye amanzi agqithisileyo akhutshwa njengomchamo. Ayilulo ulawulo oluhle?

Ziziphi izifo ezinokunxulunyaniswa nePosterior Pituitary?

Ngokubanzi, izifo eziphambili ezinxulumene nale gland azixhaphakanga. Nangona kunjalo, ngamanye amaxesha, iingxaki ezithile zinokuvela ngenxa yokukhupha kakhulu (ukukhupha kakhulu) okanye ukungakwazi ukukhupha ngokwaneleyo (ukukhupha kancinci) kwezi hormone ze-ADH kunye ne-oxytocin.

1. Ukukhupha i-ADH kancinci

Ukuba ukuveliswa okanye ukukhululwa komzimba kwehomoni ye-ADH kunciphile, izintso zilahlekelwa luphawu lokufunxa amanzi eziwadingayo. Oku kuthetha ukuba phantse onke amanzi owaselayo aphelela kumchamo wakho. Le meko ibizwa ngokuba yiCentral Diabetes Insipidus (CDI) .

Le meko inokubangelwa kukonakala kwe-hypothalamus okanye i-pituitary gland. Ngamanye amaxesha, akukho sizathu sifumanekayo.

Iimpawu eziphambili:

• Ukuchama kakhulu (iPolyuria): Ungakhupha iilitha ezininzi zomchamo ngosuku. Kusenokufuneka uye kwigumbi lokuhlambela rhoqo.
• Unxano olugqithisileyo (iPolydipsia): Nokuba usela amanzi angakanani na, uziva ngathi awufumani ngokwaneleyo. Njengoko umzimba wakho ulahlekelwa ngamanzi, ingqondo yakho ikuxelela ukuba uqhubeke usela amanzi.
• Ukuphelelwa ngamanzi emzimbeni: Ukuba awuseli manzi aneleyo, ungalahlekelwa ngamanzi emzimbeni wakho.
• Ukudinwa: Ukuvuka rhoqo ebusuku ukuze uchame kunokuphazamisa ubuthongo bakho kwaye kukwenze uzive udiniwe imini yonke.

2. Ukuba i-hormone ye-ADH iyanda (i-Hypersecretion ye-ADH)

Oku kuchasene neyangaphambili. Ukuba kukho i-hormone ye-ADH eninzi emzimbeni, izintso ziphinda zifunxe amanzi amaninzi emzimbeni. Oku kubangela ukuba kukhutshwe umchamo omninzi. Oku kubangela ukuba amanzi aqokeleleke emzimbeni kwaye inqanaba le-sodium (ityuwa) egazini libe phantsi ngendlela eyingozi. Le meko ibizwa ngokuba yi -SIADH (Syndrome of Inappropriate Antidiuretic Hormone Secretion) .

Izinto ezinokubangela oku:

• Amanye amayeza (umz., amanye amayeza esifo seswekile kunye nesifo sokuwa).
• Emva kotyando olwenziwe phantsi kwe-anesthesia.
• Iimeko ezinje ngokwenzakala engqondweni, usulelo, okanye isifo sohlangothi.

Iimpawu eziphambili (ezi zihlala zibangelwa ngamanqanaba aphantsi esodium egazini):

• Isicaphucaphu nokuhlanza.
• Intloko ebuhlungu.
• Uziva ngathi ulahlekelwa yibhalansi yakho kwaye uza kuwa.
• Utshintsho lwengqondo olufana nokulahlekelwa yinkumbulo kunye nokuxhalaba.

3. Iingxaki ezinxulumene nehomoni i-Oxytocin

Enyanisweni, izifo ezibangelwa ngamanqanaba aphantsi okanye aphezulu ale hormone, i-oxytocin, azixhaphakanga kakhulu. Yimeko engaqhelekanga kakhulu.

• Ukuba i-oxytocin iphantsi: Isibeleko sisenokunganciphi kakuhle ngexesha lokubeleka, kwaye ubisi lusenokungangeni emva kokuba umntwana ezelwe.
• Ukuba i-oxytocin iyanda: Oku kunqabile kakhulu. Kunokubangela ukuba izihlunu zesibeleko zikhule kakhulu, nto leyo eyenza kube nzima ukuba umntwana ongekazalwa akwazi ukuyibamba.

Uyazi njani ukuba kukho ingxaki ngePosterior Pituitary?

Ukuba uneempawu esizikhankanyileyo ngaphambili, ugqirha wakho uza kuqala akubuze ngeempawu zakho. Emva koko, banokwenza uvavanyo oluthile ukuze bafumane umfanekiso ochanekileyo wamanqanaba akho eehomoni.

• Uvavanyo lweGazi: Izinto ezifana namanqanaba e-ADH hormone kunye namanqanaba esodium egazini zinokulinganiswa.
• Uvavanyo lomchamo: Ungabona ukuba umchamo wakho ujiyile okanye ubhityile kangakanani.
• I-MRI scan: Oku kunceda ukujonga naziphi na iithumba okanye umonakalo kwi-pituitary gland okanye kwi-hypothalamus.

Ugqirha wakho uza kugqiba ngonyango olusekelwe kwiziphumo zezi mvavanyo.

Ndifanele ndimbone nini ugqirha?

Uninzi lweemeko esizixubushileyo aziqhelekanga. Nangona kunjalo, ukuba ubona utshintsho emzimbeni wakho, kungcono ungalubethi ngoyaba.

Ngokukodwa, ukuba unenye okanye ngaphezulu kwezi mpawu zilandelayo, musa ukuchitha ixesha uye kubona ugqirha wakho.

• Ukuba unxaniwe ngendlela engenakucingelwa kwaye uchama rhoqo, ugqithisile .
• Ukuba ufumana isicaphucaphu, ukuhlanza, intloko ebuhlungu, kunye nokuziva ungenakulinganisela ngaphandle kwesizathu.
• Ukuba ngequbuliso uziva ngathi inkumbulo yakho iyabhideka kwaye awukwazi ukugxila .

Ngamaxesha anje, ukubona ugqirha nokwenza uvavanyo olulula kunokukunceda ubone ukuba kukho ingxaki okanye akunjalo. Ngoko ke ungoyiki ukufuna ingcebiso kagqirha.
