Khawuthelekelele ukuba kukho umntu olawula umzimba wakho wonke, osebenza njenge-CEO yenkampani enkulu, kodwa omncinci njenge-pea. Loo mntu yi- Pituitary Gland . Usenokuba awuzange uve ngeli gama. Kodwa umsebenzi eliwenzayo uyamangalisa. Libandakanyeka kwizinto ezininzi ezibalulekileyo, ukusuka ekukhuleni ukuya ekubeni nomntwana. Ngoko ke namhlanje, masithethe ngalo mphathi mncinci.
Yintoni i-Pituitary Gland?
Ngamafutshane, i-pituitary gland yi-gland encinci, enobukhulu obufana ne-pea ekwisiseko sobuchopho bakho, emva nje kwebhuloho lempumlo yakho, phantsi kwe-hypothalamus. I-gland sisitho esenza izinto ezifana nee-hormone . I-pituitary gland yinxalenye yenkqubo yethu ye-endocrine.
Umsebenzi wayo ophambili kukuvelisa iihomoni ezininzi ezibalulekileyo emzimbeni nokuxelela amanye amadlala ukuba, "Kulungile, ngoku ukhupha iihomoni zakho." Yiyo loo nto siyibiza ngokuba yi-"Master Gland."
Iihormone zifana nezithunywa ezihamba emizimbeni yethu. Zihamba egazini kwaye zithwala imiyalezo kwilungu ngalinye, ulusu, kunye nemisipha. Ezi hormone zisixelela ukuba senze oku, sikwenze ngeli xesha.
I-pituitary gland yahlulwe yangamacandelo amabini aphambili.
1. I-Anterior Pituitary: Le yeyona nxalenye inkulu.
2. I-Posterior Pituitary: Inxalenye encinci ngasemva.
Le gland iqhagamshelwe kwi-hypothalamus ebuchotsheni yinxalenye encinci efana nesiqu. Kulapho i-gland ifumana khona imiyalezo evela ebuchotsheni.
Zeziphi iihomoni ezibaluleke kakhulu eziveliswa yi-pituitary gland?
Oku kusenokuvakala ngathi yisayensi kancinci, kodwa masikwenze kube lula. Kuba ezi hormone zichaphazela ubomi bethu kakhulu. Ndiza kubeka oku kwitheyibhile entle ukuze ukuqonde lula.
| Igama lehomoni | Inxalenye ekhutshiweyo | Yintoni eyona nto iphambili oyenzayo? |
|---|---|---|
| Ihomoni ye-Adrenocorticotropic (ACTH) | Inxalenye engaphambili | Xa siziva sixinezelekile, kusinceda sikwazi ukumelana nalo. Kuvuselela amadlala e-adrenal, abekwe phezu kwezintso, ukuze avelise i-cortisol, "i-hormone yoxinzelelo." |
| Ihomoni evuselela i-follicle (FSH) | Inxalenye engaphambili | Inceda ekuveliseni isidoda emadodeni . Ivuselela ama-ovari kubasetyhini ukuba avelise i-hormone i-estrogen kwaye incede ekukhuleni kwamaqanda. |
| IHormone yoKhula (GH) | Inxalenye engaphambili | Ibalulekile ekukhuleni komzimba kwabantwana , kuquka nobude. Inceda ukugcina izihlunu namathambo esempilweni kubantu abadala kwaye ilawula ukusasazwa kwamafutha. |
| I-hormone ye-Luteinizing (LH) | Inxalenye engaphambili | Inceda abafazi ukuba bakhuphe amaqanda. Inceda amadoda ukuba avelise i-testosterone kumasende abo . |
| Iprolactin | Inxalenye engaphambili | Le yeyona hormone iphambili enceda oomama ukuba bavelise ubisi emva kokubeleka. Ingachaphazela nokuzala kubantu abadala. |
| Ihomoni evuselela i-thyroid (TSH) | Inxalenye engaphambili | Inika imiqondiso kwi-thyroid gland entanyeni ukuba "iqale ukusebenza." Iihomoni ze-thyroid zilawula izinto ezifana ne-metabolism yethu kunye namanqanaba amandla. |
| Ihomoni yokulwa nomchamo (ADH) | Inxalenye engasemva | Ilawula ibhalansi yamanzi kunye nesodium (ityuwa) emzimbeni. Ukuba oku kuyancipha, kuya kubakho ukuchama rhoqo. |
| I-Oxytocin | Inxalenye engasemva | Inceda isibeleko ukuba sinciphe ukuze sibeleke umntwana . Ikwanceda ukuhamba kobisi ngexesha lokuncancisa kwaye inceda ekudaleni ubudlelwane phakathi komama nomntwana. |
Ngaba umntu angaphila ngaphandle kwe-pituitary gland?
Ewe, kunokwenzeka. Kodwa kukho imeko. Umntu ongenalo i-pituitary gland kuya kufuneka athathe ii-hormone ezibalulekileyo eziveliswa yiloo gland njengeyeza ubomi bakhe bonke. Ngaphandle kwezi hormone, iinkqubo ezininzi ezibalulekileyo emzimbeni wethu bezingenakwenzeka. Ke ngoko, ukuba azinyangwa, ukulahleka kwazo zonke ii-hormone ze-pituitary kunokuba yingozi ebomini.
Ngoko ke, yintoni imisebenzi ephambili ye-pituitary gland?
Masiqonde oku ngomzekelo olula kakhulu. Cinga nge-thermostat ekwi-AC yakho ekhaya. Ihlala ijonga ubushushu kwigumbi kwaye ivula/icime i-AC xa kufuneka igcinwe ikwinqanaba elikhululekileyo, akunjalo?
I-pituitary gland ifana ne-thermostat yomzimba wethu. Ihlala ijonga umsebenzi womzimba, ithumela ii-hormones ezibizwa ngokuba zii-hormones kwizitho ezahlukeneyo kunye namadlala, zisithi, "Kulungile, yenza oku ngoku," "Nyusa inqanaba loku kancinci," "Yeka oku ngoku."
Imisebenzi ephambili ngokufutshane:
- Ukulawula ukukhula komzimba .
- I-Metabolism - Le yindlela esiguqula ngayo ukutya esikutyayo kube ngamandla.
- Ukuzala , oko kukuthi, ukukwazi ukuzala abantwana.
- Ukuphendula kuxinzelelo okanye kwingozi.
- Ukuveliswa kobisi lwebele.
- Ukulawula amanqanaba amanzi netyuwa emzimbeni.
- Ukunceda ngenkqubo yokuzalwa.
Ziziphi izifo ezinokunxulunyaniswa ne-pituitary gland?
Xa umsebenzi wale gland incinci uphazamisekile, iingxaki ezahlukeneyo zinokwenzeka. Ezi zinokwahlulwa zibe ziintlobo ezine.
1. Ii-Adenomas zePituitary
Ezi zii-tumor ezingezizo umhlaza (ezingenobungozi) ezikhula kwi-pituitary gland. Zimalunga ne-10%-15% yee-tumor ezingaphakathi kwentloko. Ezi tumor zihlala zikhula zibe nkulu kakhulu.
- Ukuba ithumba liyakhula: Linokucinezela imithambo-luvo eyijikelezileyo, ingakumbi leyo ibandakanyeka ekuboneni. Oku kunokubangela iintloko ezibuhlungu kunye neengxaki zokubona (ingakumbi ukulahleka kokubona okusecaleni).
- Iithumba ezivelisa iihomoni: Ezinye iithumba zivelisa iihomoni ngendlela engaqhelekanga. Umzekelo, ithumba elivelisa ihomoni yeprolactin eninzi (iProlactinoma) linokubangela ukuba abafazi abangancancisiyo babe nokukhupha ubisi emabeleni abo kunye nemijikelo yokuya exesheni engacwangciswanga.
- Iithumba ezingezizo iihomoni: Ezinye iithumba azivelisi iihomoni. Ziba yingxaki kuphela xa ithumba likhula likhulu kwaye licinezela imithambo-luvo ekufutshane.
2. Ukungabi namdla kwizinto ezithile
Oku kwenzeka xa i-pituitary gland ivelisa ngaphantsi komlinganiselo ofunekayo we-hormone enye okanye ezingaphezulu. Oku kunokubangelwa kukonakala kwe-gland, utyando, okanye unyango lwe-radiation engqondweni.
3. I-Hyperpituitarism
Kulapho i-pituitary gland ivelisa iihomoni ezingaphezulu kwesinye okanye ezingaphezulu kunezo zifunekayo. Oku kudla ngokubangelwa yi-pituitary adenoma (ithumba) evelisa iihomoni.
Makhe sijonge iimeko eziphambili ezibangelwa kukungalingani kwamahomoni.
| Imeko | Inkcazo |
|---|---|
| I-Acromegaly | Ukuveliswa kakhulu kwehomoni yokukhula (GH) ngexesha lokukhula. Ibonakala ngokwandiswa okungaqhelekanga kwamalungu omzimba afana nezandla, iinyawo, kunye namathambo obuso. |
| Ubugorha obukhulu | Ukuveliswa kakhulu kwehomoni yokukhula (GH) ngexesha lobuntwana kubangela ukuba umntwana akhule ngokungaqhelekanga. |
| Isifo sikaCushing | Ukwanda kwamanqanaba e-cortisol ngenxa yokuveliswa ngokugqithisileyo kwe- ACTH hormone. Oku kubonakala ngokugcwala kwamafutha kwiindawo ezithile zomzimba (ubuso, isisu, umva wentamo), uxinzelelo lwegazi oluphezulu, kunye namanqanaba aphezulu eswekile. |
| Ukungabikho kwehomoni yokukhula | Ukungakwazi ukukhula kakuhle nokungakwazi ukukhula kakuhle ebantwaneni. Iingxaki zemetabolism kubantu abadala. |
| I-Central Diabetes Insipidus | Ukungabikho kwehomoni ye -ADH . Oku kubangela ukuba umzimba ungagcini manzi kwaye ukhuphe umchamo omninzi. (Oku akusiyo i-diabetes mellitus, oko kukuthi, i-diabetes mellitus). |
| I-Hypogonadism (i-Central Hypogonadism) | Ukunqongophala kwee-hormone ze-LH kunye ne-FSH . Oku kubangela iingxaki zokusebenza ngokwesondo kunye nokuzala kumadoda nabasetyhini. |
4. I-Empty Sella Syndrome
Le yimeko engaqhelekanga. Ibangelwa yingxaki kwi-bony sac (sella turcica) apho kukho i-pituitary gland, nto leyo ebangela ukuba i-gland ibe buthathaka okanye inciphe. Oku kudla ngokufumaneka ngengozi kwi-scan. Ukuba amanqanaba e-hormone aqhelekile, oku akubangeli ngxaki.
Uyazi njani ukuba kukho ingxaki kwi-pituitary gland? Zithini iimpawu?
Iimpawu zengxaki ye-pituitary gland zahluka kakhulu, kuxhomekeke ekubeni yeyiphi i-hormone echaphazelekayo kwaye, ukuba kukho ithumba, likhulu kangakanani.
Iimpawu eziqhelekileyo (ezibangelwa ziithumba ezinkulu):
- Intloko ebuhlungu rhoqo nengapheliyo.
- Utshintsho embonweni, ingakumbi ukulahlekelwa kukubona okusecaleni.
Iimpawu ezinokubangela ukungalingani kwamahomoni:
- Ukukhula kwabantwana kuyaphazamiseka okanye kukhawuleze ngendlela engaqhelekanga.
- Ukungazali kumadoda nakubafazi.
- Imijikelo yokuya exesheni yabasetyhini ayiqhelekanga okanye iyeke ngokupheleleyo.
- Ukunyuka okanye ukwehla kobunzima ngaphandle kwesizathu.
- Ukudandatheka okanye ixhala.
- Ukuziva udiniwe kakhulu emzimbeni.
Ukuba uneempawu ezintsha nezingapheliyo ezifana nezi, ungazityesheli. Kusenokwenzeka ukuba zinxulumene okanye azinxulumene ne-pituitary gland. Ngoko ke eyona nto ingcono onokuyenza kukubona ugqirha wakho uze ufumane ingcebiso.
Ngubani onyanga ezi ngxaki? Ingaba isifo sifunyanwa njani?
Iingxaki ze-pituitary gland kunye ne-hormone zinyangwa yi-endocrinologist. Unokwenza uvavanyo olufunekayo ngokusekelwe kwiimpawu zakho, axilonge imeko, aze acwangcise unyango. Ukuba ufuna ukususa into efana nethumba ngotyando, unokufuna uncedo kugqirha wemithambo-luvo .
Ezi mvavanyo zilandelayo zisetyenziswa kakhulu ekuxilongeni isifo:
- Uvavanyo lwegazi: Ulwazi oluninzi lunokufunyanwa ngokulinganisa amanqanaba eehomoni ezahlukeneyo egazini.
- I-MRI scan: Oku kubaluleke kakhulu ukuze ufumane umfanekiso ocacileyo wengqondo kunye ne-pituitary gland kwaye ubone ukuba kukho ithumba okanye enye into engaqhelekanga.
Singayigcina njani i-pituitary gland yethu isempilweni?
Eyona nto ingcono esinokuyenza kukukhusela iintloko zethu. I-Traumatic Brain Injuries (TBI) inokonakalisa le gland ibuthathaka. Ke ngoko,
- Nxiba ibhanti lokhuseleko nanini na xa usemotweni.
- Qiniseka ukuba unxibe isigcina-ntloko xa ukhwela iibhayisekile, iibhayisekile, okanye udlala imidlalo.
- Zikhusele ekuweni. Lumka kwiindawo ezityibilikayo neziyingozi ekhayeni lakho, ingakumbi ukuba unabantu abadala.
- Ukuba unabantwana abancinci, qiniseka ukuba indawo abadlala kuyo nabachitha ixesha kuyo ikhuselekile.
Le mikhwa mincinci inokunceda kakhulu ekuthinteleni umonakalo kwingqondo yethu nakweli gland lixabisekileyo.
Umyalezo Wokuya Ekhaya
- I-pituitary gland sisitho esilingana ne-pea esiphantsi kwengqondo yakho, kodwa sisitho esinamandla kakhulu esisebenza njenge-"Master Gland" yomzimba.
- Izinto ezininzi, ezinje ngokukhula komzimba wakho, imetabolism, ukuzala, kunye nokuphendula kuxinzelelo, zilawulwa ziihormones ezikhutshwa apha.
