Tiyeni tingophunzira za Anterior Pituitary Gland (Adenohypophysis): kam'ng'ono kolamulira muubongo wathu!

Kodi munayamba mwadzifunsapo kuti kachiwalo kakang'ono ka thupi lathu kamagwira ntchito yochuluka bwanji? Malo amodzi odabwitsa ndi anterior pituitary gland yomwe tikambirane lero. Anthu ena amaitchanso kuti ``Adenohypophysis``. Monga wotsogolera gulu la okestra, gland iyi ili ndi udindo wopanga ndi kutulutsa mahomoni omwe amalamulira ntchito zambiri zofunika kwambiri m'thupi.

Ndiye, kodi chithokomiro cha pituitary ichi ndi chiyani?

Mwachidule, iyi ndi gawo lakutsogolo kwa pituitary gland yanu. Pituitary gland ndi kachiwalo kakang'ono kofanana ndi nandolo, komwe kali pansi pa ubongo wanu, pansi pa hypothalamus. Ichi ndi gawo la dongosolo lanu la endocrine. Ndiko kuti, gawo lomwe limayang'anira magwiridwe antchito a glands zosiyanasiyana m'thupi.

Tangoganizani kuti pituitary gland yanu ili ndi magawo awiri: anterior lobe (ndiyo anterior pituitary gland yomwe tikukamba lero) ndi posterior lobe. Anterior lobe iyi ndi yomwe imapanga mahomoni pafupifupi asanu ndi limodzi (6) ndipo imawatulutsa m'thupi. Mahomoni awa ndi omwe thupi lathu limapanga:

• Kukula (tikukula)
• Kagayidwe kachakudya (kupanga mphamvu m'thupi, kuyaka zinthu)
• Kubereka (kuthekera kobereka ana)
• Kuyankha kupsinjika maganizo
• Kuyamwitsa (kwa amayi)

Zinthu zambiri zofunika zimalamuliridwa. Ngakhale ali wamng'ono, ndi munthu wotanganidwa kwambiri komanso wamphamvu!

Ndiye, kodi mahomoni enieni omwe gland ya anterior pituitary imapanga ndi ati?

Pali mahomoni akuluakulu asanu ndi limodzi omwe amapanga bwana wamng'ono uyu. Tiyeni tiwone zomwe ali komanso zomwe amachita.

1. Adrenocorticotropic Hormone (ACTH): Ichi ndi chomwe chimalimbikitsa ma adrenal glands anu kuti apange cortisol, yomwe imadziwikanso kuti "stress hormone," ndi mahomoni ena. Izi ndizofunikira kwambiri panthawi yamavuto, monga pamene mukuopa.

2. Homoni yolimbikitsa ma follicle (FSH): Mwa amuna, imalimbikitsa ma testes kuti apange umuna. Mwa akazi, imalimbikitsa mazira okhwima m'ma ovary, kuwakonzekeretsa kuti ayambe ovulation, ndikupanga hormone ya estrogen.

3. Luteinizing Hormone (LH): Ngati ndinu mkazi, LH imalimbikitsa mazira kuti apange progesterone. Ngati ndinu mwamuna, imalimbikitsa kupanga testosterone.

4. Homoni Yokulitsa Thupi la Munthu (HGH): Iyi ndi yofunika kwambiri pakukula kwa ana aang'ono. Imawathandiza kukula ndikukhala ndi thupi lolimba. Kwa akuluakulu, imathandiza kusunga minofu ndi mafupa athanzi, ndipo imakhudza momwe mafuta amasungidwira m'thupi.

5. Prolactin:Homoni iyi imalimbikitsa kupanga mkaka mayi akakhala ndi mwana. Ingakhudzenso nthawi ya msambo, mphamvu yobereka (kuthekera kobereka ana), komanso ntchito yogonana.

6. Homoni yolimbikitsa chithokomiro (TSH): Ichi ndi chomwe chimauza chithokomiro chanu kuti chipange ndikutulutsa mahomoni akeake. Mahomoni a chithokomiro ndi ofunikira kuti thupi lathu lizigwira ntchito bwino.

Mukuona, ntchito zosiyanasiyana zingati zomwe zingachitike m'malo ang'onoang'ono awa!

Kodi chithokomiro cha pituitary cha anterior chimagwira ntchito bwanji ndi ziwalo zina?

Gland yanu ya anterior pituitary imalumikizidwa mwachindunji ndi gawo la ubongo wanu lotchedwa hypothalamus. Hypothalamus imatulutsa "mahomoni otulutsa" ndi "mahomoni oletsa" monga somatostatin ndi dopamine m'magazi kudzera mu pituitary duct (gawo laling'ono longa chubu lomwe limalumikiza ubongo ndi pituitary gland). Mahomoni otulutsa awa amalimbikitsa kapena kuletsa kupanga mahomoni ndi anterior pituitary gland. Hypothalamus ndi anterior pituitary gland ali ngati anthu awiri omwe amalankhulana nthawi zonse ndikugawana chidziwitso.

Pambuyo poti mahomoni atulutsidwa kuchokera ku anterior pituitary gland, amalumikizana ndikukhudza ziwalo zina zambiri, ma glands, ndi minofu m'thupi lathu. Mwachitsanzo:

• Mafupa athu, minofu, ndi ziwalo zina zamkati
• Zilonda za Adrenal
• Chithokomiro cha chithokomiro
• Mazira ndi machende (ndiko kuti, ma genital obereketsa)
• Ma glands otulutsa mkaka (ma glands otulutsa mkaka)

Kodi chithokomiro cha pituitary ichi chili kuti kwenikweni?

Monga tanenera kale, pituitary gland yanu ili pansi pa ubongo wanu, kumbuyo kwa mlatho wa mphuno yanu, pansi pa ``Hypothalamus``. Ili mu chipinda chaching'ono, kapena thumba, mu fupa lomwe lili m'chigaza chanu lotchedwa sphenoid bone. Madokotala amatcha ichi ``Sella Turcica``.

Pituitary gland yanu ili ndi ma lobes awiri omwe amagwirizana. Pituitary gland ya anterior ili kutsogolo, moyang'anizana ndi kutsogolo kwa mutu wanu. Pituitary gland ya posterior gland ili kumbuyo. Koma zodabwitsa, pituitary gland ya anterior ndi yayikulu kuposa ya posterior gland. Pafupifupi 80% ya kulemera kwa pituitary gland yonse ili kutsogolo uku.

Ndi mavuto ati omwe angachitike ndi anterior pituitary gland?

Popeza kuti gland iyi imapanga mahomoni ambiri ofunikira, mavuto aliwonse omwe ali nawo angayambitse mavuto osiyanasiyana azaumoyo. Mavutowa nthawi zambiri amatha kugawidwa m'magulu awiri:

1. Hypopituitarism: Izi zikutanthauza kuti pituitary gland imapanga mahomoni ochepa kuposa momwe amafunikira.

2. Kuthamanga kwa magazi m'thupi:Izi zikutanthauza kuti pituitary gland ikupanga mahomoni ambiri kuposa momwe akufunira.

Pali zifukwa zingapo zazikulu zomwe nthawi zambiri zinthu ziwirizi zimachitika:

• Ziphuphu za pituitary gland (adenomas): Izi nthawi zambiri si zotupa za khansa (zosavulaza).
• Kuwonongeka kwa anterior pituitary gland, hypothalamus, kapena pituitary duct: Izi zitha kuchitika chifukwa cha ngozi, matenda, kapena kutuluka magazi (monga pituitary apoplexy).
• Matenda a majini: Mwachitsanzo, matenda monga `(Multiple Endocrine Neoplasia - MEN)`.

Matenda ena omwe amayamba chifukwa cha `Hypopituitarism` (kusowa kwa mahomoni):

Kusowa kwa mahomoni amodzi kapena angapo kungayambitse matenda monga:

• Kulephera kwa adrenal kwachiwiri: Kulephera kugwira ntchito kwa adrenal gland chifukwa cha kuchepa kwa ACTH hormone.
• Kusowa kwa mahomoni okhwima (GHD): Kuchepa kwa mahomoni otchedwa HGH. Mwachidule, kukula kumatha kuchedwa.
• Kuchepa kwa mahomoni ogonana m'thupi: Kuchepa kwa kupanga mahomoni ogonana kuchokera ku tiziwalo toberekera (mazira kapena machende) chifukwa cha kuchepa kwa mahomoni a FSH ndi/kapena LH.
• Hypothyroidism yapakati: Hypothyroidism chifukwa cha kuchepa kwa hormone ya TSH.

Matenda ena omwe amayamba chifukwa cha `Hyperpituitarism` (kuwonjezeka kwa mahomoni):

Kuwonjezeka kwa mahomoni amodzi kapena angapo kungayambitse matenda monga:

• Acromegaly: Matenda osowa omwe amayamba chifukwa cha kuchuluka kwa HGH mwa akuluakulu. Pa vutoli, mafupa ndi minofu zimakula modabwitsa.
• Gigantism: Mwana wamtali kwambiri kapena wachinyamata amene amakhala ndi mahomoni ambiri a HGH. Izi zimachitika kawirikawiri.
• Matenda a Cushing: Kupanga kwambiri kwa mahomoni a ACTH kumapangitsa kuti ma adrenal glands apange cortisol yochulukirapo. Uwu ndi mtundu wa vuto lotchedwa Cushing's syndrome.
• Hyperprolactinemia: Kupanga kwambiri kwa hormone ya prolactin.
• Kuchuluka kwa chithokomiro m'thupi: Chithokomiro chogwira ntchito mopitirira muyeso chifukwa cha kupanga kwambiri kwa TSH. Ichi ndi chifukwa chosowa kwambiri cha hyperthyroidism.

Tiyeni tiphunzire pang'ono za Pituitary Adenomas.

Adenoma ya pituitary ndi chotupa chomwe chimakula pang'onopang'ono mu pituitary gland yanu. Koma musadandaule, nthawi zambiri izi zimakhala zotupa zomwe zikukula pang'onopang'ono, osati khansa (zoyipa).

Komabe, ma adenoma amenewa amatha kutsekereza maselo abwinobwino a pituitary ndikulepheretsa kugwira ntchito bwino. Izi zingayambitse ``Hypopituitarism`` (kupanga mahomoni ochepa), makamaka ngati chotupacho ndi chachikulu. Nthawi zina, zotupazi zimathanso kupanga mahomoni owonjezera, omwe angayambitse ``Hyperpituitarism`` (kupanga mahomoni ambiri).

Pali mitundu ingapo ya adenomas ya anterior pituitary yomwe imapanga mahomoni (yogwira ntchito):

• Prolactinoma: Imapanga mahomoni ochulukirapo a prolactin. Uwu ndiye mtundu wofala kwambiri wa pituitary adenoma.
• Somatotroph adenoma: Imapanga mahomoni okulirapo kwambiri (GH).
• Corticotroph adenoma: Imapanga mahomoni ochulukirapo a ACTH.
• Thyrotroph adenoma: Imapanga mahomoni ambiri a TSH.
• Gonadotroph adenoma: Imapanga mahomoni ochulukirapo a LH ndi FSH.

Kodi pali mayeso aliwonse omwe angatsimikizire ngati chithokomiro changa cha anterior pituitary chili bwino?

Inde, ngati muli ndi zizindikiro za vuto ndi anterior pituitary gland, dokotala wanu mwina angalamule kuti mufufuze kuchuluka kwa mahomoni. Izi nthawi zambiri zimakhala mayeso a magazi .

Ngati zotsatira za mayeso anu a magazi zikusonyeza zachilendo, dokotala wanu angakulangizeni chinthu monga MRI scan kuti muwone pituitary gland yanu.

Ndiye, kodi tingatani kuti chithokomiro cha pituitary ichi chikhale chathanzi?

Kunena zoona, simungathe kupewa mavuto a pituitary gland nthawi zonse. Koma chinthu chimodzi chofunikira chomwe mungachite ndikusamalira mutu wanu. Kuvulala mutu, makamaka kuvulala koopsa muubongo (TBIs), kungawononge pituitary gland yanu. Ngati zimenezo zitachitika, ikhoza kupanga mahomoni ambiri kapena ochepa kwambiri.

Nazi zina zomwe mungachite kuti mupewe kuvulala mutu ndi ubongo:

• Nthawi zonse muzivala lamba wa chitetezo mukamakwera galimoto.
• Thamangitsani mosamala.
• Valani chisoti mukamakwera njinga, njinga yamoto, kapena mukamasewera masewera amphamvu.
• Chitani zinthu zopewera kugwa, makamaka ngati muli pachiopsezo chachikulu chogwa. Mutha kuchita zinthu monga kuchotsa zopinga m'nyumba mwanu, kugwiritsa ntchito chothandizira kuyenda, komanso kusunga maso anu ali oyera.
• Ngati muli ndi ana aang'ono, sungani malo awo osewerera otetezeka.

Kumbukirani: Chiwalo chanu cha pituitary cha anterior ndi chiwalo chaching'ono, koma champhamvu, komanso chofunikira chomwe chimapanga mahomoni osiyanasiyana omwe amakhudza mbali zambiri za thanzi lathu.

Pomaliza, zinthu zoti muzikumbukira

Kotero, mutha kuwona kufunika kwa gland iyi ya anterior pituitary m'thupi lathu. Chifukwa cha zimenezi, nthawi zina zimakhala zovuta kudziwa ngati zizindikiro zina zimachitika chifukwa cha vuto la gland iyi ya pituitary kapena china chake.

Chofunika kwambiri ndichakuti ngati mukupeza zizindikiro zatsopano zachilendo, kapena ngati mukuda nkhawa ndi chizindikiro chomwe muli nacho kale, onetsetsani kuti mwawonana ndi dokotala ndikukambirana za icho.Akhoza kuchita mayeso ochepa osavuta kuti aone thanzi lanu. Ngati pali vuto, likhoza kuzindikirika ndikuchiritsidwa mwachangu.
