Ngaba wakha wazibuza ukuba ngubani olawula izinto ezininzi kangaka emzimbeni wakho, njengokukhula kwakho, ubunzima, uxinzelelo, kunye nokukwazi ukuba nabantwana? Emva kwako konke oku kukho isidalwa esincinci kodwa esinamandla kakhulu. Eso sisitho esibizwa ngokuba yi-Anterior Pituitary, esisezantsi kwengqondo yethu. Namhlanje, siza kuthetha ngalo mphathi mncinci.
Ngamafutshane, yintoni i-Anterior Pituitary?
I-Anterior Pituitary ibhekisa kwinxalenye engaphambili ye-pituitary gland yakho. Ikwabizwa ngokuba yi-"Adenohypophysis" kwisayensi yezonyango. Le pituitary gland incinci kakhulu, njenge-pea. Kodwa umsebenzi wayo mkhulu kakhulu. Ikwisiseko sobuchopho bakho, phantsi kwe-"Hypothalamus".
Khawuthelekelele ukuba imizimba yethu ifana ne-orchestra enkulu. Ke le Anterior Pituitary gland ngumqhubi we-orchestra. Yiyo enika umsebenzi kwamanye ama-glands amaninzi emzimbeni kwaye iqinisekise ukuba awenza ngokufanelekileyo. Ngamanye amazwi, yenza umsebenzi omhle wokugcina ibhalansi yenkqubo ye-hormone emzimbeni wethu.
I-pituitary gland ineenxalenye ezimbini eziphambili:
1. I-Anterior Lobe: Le yi-Anterior Pituitary esithetha ngayo namhlanje.
2. I-Posterior Lobe: Le yenza eminye imisebenzi embalwa.
I-Anterior Pituitary ivelisa kwaye ikhuphe iihomoni ezintandathu (6) ezibalulekileyo emzimbeni wethu egazini. Ezi homoni zilawula izinto ezininzi emzimbeni wethu.
- Ukukhula
- I-Metabolism
- Ukuzala kwakhona
- Impendulo yoxinzelelo
- Ukuveliswa kobisi lwebele (ukuncancisa)
Zeziphi iihomoni eziveliswa yi-Anterior Pituitary gland?
Kulungile, ngoku makhe sijonge iihomoni ezi-6 ezibalulekileyo ezikhutshwa yile nkosi incinci emizimbeni yethu, kwaye kwenzeka ntoni kuzo. Ukuze kube lula ukukhumbula oku, makhe sijonge itafile.
| Ihomoni | Yintoni omawuyenze ngokulula |
|---|---|
| IHormone ye-Adrenocorticotropic (ACTH) | Ivuselela amadlala e-adrenal, akwiintso zethu, ukuba avelise i-hormone i -cortisol , esinceda sikwazi ukumelana noxinzelelo. |
| Ihomoni evuselela i-follicle (FSH) | Ivuselela ama-ovari kubasetyhini ukuze ibancede bakhule kwaye bavelise i-hormone ye-estrogen . Ivuselela amasende kumadoda ukuze ibancede bavelise isidoda. |
| I-Luteinizing Hormone (LH) | Inceda ama-ovari abasetyhini ukuba avelise i-hormone i-progesterone . Inceda amadoda ukuba avelise i-hormone i-testosterone . |
| IHormone Yokukhula Komntu (HGH) | Ibalulekile ekuphuhlisweni komzimba kwabantwana. Inceda ukugcina izihlunu namathambo esempilweni kubantu abadala kwaye ilawula ukusasazwa kwamafutha emzimbeni. |
| Iprolactin | Ivuselela ukuveliswa kobisi lwebele emva kokubeletha. Ikwachaphazela nomjikelo wokuya exesheni, ukuzala, kunye nokusebenza ngokwesondo. |
| Ihomoni evuselela i-thyroid (TSH) | Ivuselela i-thyroid gland entanyeni, nto leyo ebangela ukuba ivelise ii-hormone ze-thyroid. Ezi hormone zibalulekile ekulawuleni izinga le-metabolism emzimbeni wethu. |
Ziziphi izifo ezinxulumene ne-Anterior Pituitary Gland?
Ngenxa yokuba le gland ilawula iihomoni ezininzi kangaka, nokuba yingxaki encinci ngayo inokubangela iingxaki ezininzi zempilo. Ezi ngxaki ngokubanzi zinokwahlulwa zibe ziintlobo ezimbini eziphambili.
1. I-Hypopituitarism: Oku kuthetha ukuba i-pituitary gland ayisebenzi ngokwaneleyo, oko kuthetha ukuba ayivelisi ngokwaneleyo iihomoni ezifunekayo.
2. I-Hyperpituitarism: Oku kuthetha ukuba i-pituitary gland isebenza kakhulu, ivelisa iihomoni ezininzi kunokuba kuyimfuneko.
Kukho izizathu ezininzi eziphambili zokuba ezi meko zenzeke:
- Iithumba ezikhula kwi-pituitary gland - ezi zibizwa ngokuba yi-"pituitary adenomas".
- Umonakalo kwi-Anterior Pituitary, Hypothalamus, okanye kwimibhobho edibanisa zona ngenxa yokwenzakala, usulelo, okanye ukopha (`(pituitary apoplexy)`).
- Ezinye iimeko zemfuza, umzekelo `i-multiple endocrine neoplasia (MEN)`.
Izifo ezibangelwa ngamanqanaba aphantsi eehomoni (i-Hypopituitarism)
Ezi meko zinokwenzeka ngenxa yokuncipha kwehomoni enye okanye ezingaphezulu eziveliswa yi-pituitary gland.
| Imeko yezonyango | Ingcaciso elula |
|---|---|
| Ukungakwazi ukusebenza kakuhle kwe-adrenal yesibini | Ukusebenza kwamadlala e-adrenal kuyehla ngenxa yokuncipha kwemveliso ye-ACTH hormone. |
| Ukungabikho kwehomoni yokukhula (GHD) | Ihomoni yokukhula (i-HGH) ayiveliswanga ngokwaneleyo. Le yimbangela yokuba abantwana bakhule kancinci. |
| I-hypogonadism ephakathi | Ukwehla kweehomoni ze-FSH kunye ne-LH kubangela ukwehla kwemveliso yeehomoni zesini ezivela kuma-ovari okanye kuma-testicles. |
| I-hypothyroidism ephakathi | Ukwehla kwe-hormone ye-TSH kubangela ukwehla komsebenzi we-thyroid. |
Izifo ezibangelwa kukunyuka kwamanqanaba e-hormone (i-Hyperpituitarism)
Ezi meko zibangelwa kukuveliswa ngokugqithisileyo kwehomoni enye okanye ezingaphezulu ze-pituitary.
| Imeko yezonyango | Ingcaciso elula |
|---|---|
| I-Acromegaly | Ukuveliswa ngokugqithisileyo kwehomoni yokukhula kwabantu abadala (i-HGH), ebangela ukukhula okungaqhelekanga kwamathambo kunye nezicubu (umz., ukwandiswa kwezandla, iinyawo, nobuso). |
| Ubugorha obukhulu | Ukuveliswa kakhulu kwehomoni yokukhula ngexesha lobuntwana okanye lokufikisa, nto leyo ebangela ubude obungaqhelekanga. |
| Isifo sikaCushing | Ukuveliswa kakhulu kwehomoni i-ACTH kubangela ukuba umzimba uvelise amanqanaba aphezulu e-cortisol. Olu luhlobo lwemeko ebizwa ngokuba yi-'Cushing's syndrome.' |
| I-Hyperprolactinemia | I-hormone yeprolactin iveliswa ngokugqithisileyo. |
| I-hyperthyroidism ephakathi | I-thyroid gland iqalisa ukusebenza kakhulu ngenxa yokuveliswa kakhulu kwehomoni i-TSH (le yimeko engaqhelekanga kakhulu). |
Into ebalulekileyo kukuba ezi mpawu zidla ngokufana nezezinye izifo. Ngoko ke ukuba ukrokrela ukuba unengxaki efana nale, bona ugqirha wakho ngokukhawuleza ukuze akunike ingcebiso.
Ugqirha uyijonga njani impilo yale gland?
Ukuba uneempawu zengxaki ye-pituitary gland, ugqirha wakho uya kuqala ajonge amanqanaba akho e-hormone. Oku kunokwenziwa ngovavanyo lwegazi .
Ukuba kukho naziphi na iingxaki kwezo ngxelo zovavanyo, ugqirha wakho unokucebisa into efana ne-MRI scan ukuze kujongwe ngokusondeleyo i-pituitary gland.
Ndingayigcina njani i-Anterior Pituitary gland yam isempilweni?
Enyanisweni, iingxaki zale gland azinakuthintelwa rhoqo. Kodwa kukho into ebalulekileyo esinokuyenza. Oko kukukhusela iintloko zethu.
Ukulimala entloko kunye nokwenzakala kwengqondo okubuhlungu (iiTBI) kunokonakalisa i-pituitary gland, nto leyo enokubangela ukwehla okanye ukwanda kwemveliso yeehomoni.
Ngoko ke, nazi ezinye izinto onokuzenza ukuze ukhusele intloko yakho:
- Nxiba ibhanti lokhuseleko nanini na xa usemotweni.
- Qhuba ngokukhuselekileyo.
- Nxiba isigcina-ntloko xa ukhwela ibhayisekile, ibhayisekile, okanye udlala imidlalo (ingakumbi imidlalo enokuquka ukungqubana).
- Thatha amanyathelo okuthintela ukuwa. Oku kubaluleke kakhulu kubantu abadala. Susa iindawo ezityibilikayo nezinto ezinokubangela ukukhubeka.
- Ukuba unabantwana abancinci, qiniseka ukuba iindawo abadlala kuzo nabachitha ixesha kuzo zikhuselekile.
I-Anterior Pituitary yindlala encinci kodwa enamandla enefuthe kwiinkalo ezininzi zempilo yethu. Ngoko ke ukuba uneempawu ezintsha okanye ezixhalabisayo, musa ukucinga nje ukuba yinto eyahlukileyo, kodwa soloko uthetha nogqirha. Banokufumana umfanekiso ochanekileyo wempilo yakho ngovavanyo olulula.
Umyalezo Wokuya Ekhaya
- I-Anterior Pituitary yindlala enobukhulu obufana ne-pea, kodwa ebaluleke kakhulu, ekwisiseko sobuchopho bakho.
- Ivelisa iihomoni ezi-6 ezilawula imisebenzi ebalulekileyo yomzimba efana nokukhula, imetabolism, kunye nokuzala.
- Iimeko ezahlukeneyo zempilo zinokwenzeka ngenxa yokugqithisa (i-hyperpituitarism) okanye ukunqongophala (i-hypopituitarism) kwezi hormone.
- Kubaluleke kakhulu ukukhusela intloko, njengoko ukwenzakala entloko kungonakalisa le gland.
- Ukuba uneempawu ezinxulumene nengxaki yehomoni, ungathandabuzi ukubona ugqirha wakho ngokukhawuleza ukuze akunike icebiso.
