Kodi pituitary England? Ali pituitary England?

Zinsinsi za thupi chiyani siutha kwa zaka zambiri mu mzere. Ndipo pamene asayansi apeza kuti ndi pituitary England, zambiri amakhalabe osadziwika. Izi England endocrine ili pansi pa kutumphuka wa hemispheres oziziritsa mu chishalo mafupa chigaza.

Ulamuliro ali ndi mawonekedwe anamaliza ndi kukula laling'ono, akulemera 0,5 ga anthu ambiri kudziwa kumene pituitary England, koma za kufunika kwa ntchito ya Chapafupi executable osati onse. Kufunika kwa iyo ili n'zovuta Musaone, chifukwa zimakhudza kagayidwe, kukula ndi chitukuko.

Kapangidwe ka pituitary England: mapangidwe

Anthu Pituitary mbali ziwiri: mbali kutsogolo (otchedwa adenohypophysis) ndi gawo kumbuyo (neurohypophysis). Iye ali pa ubwenzi ndi ubongo imene imalamulira kutentha kudzera nyuzi ya. Ndi ku mbali imeneyi pituitary England kugwa zinthu kupangidwa mahomoni. cholowa onse ntchito motsogozedwa ndi ubongo imene imalamulira kutentha kwa, ngakhale kuti thupi ili chapakati ndi lofunika kwambiri mu dongosolo endocrine m'thupi la munthu.

zapambuyo Lobe

Kupereka khalidwe la gawo ili, ife adzayankha funso kodi pituitary England. Kapangidwe ka Lobe zapambuyo tichipeza osiyanasiyana maselo glandular endocrine. Iye, nayenso ali anagawa mu magawo angapo:

• Wapotalikira. Amalima yaikulu kuchuluka mahomoni.
• Tubular. Ndi kupitiriza kwa wina m'mbuyomu, koma pa ntchito Sizikudziwika kuyambira dera ili bwino bwino kwa asayansi.
• Wapakatikati. Kuyambira mutu zikuonekeratu kuti lili pakati pa awiri tafotokozazi.

nyumba imeneyi lili ndi pituitary England. Ntchito ya pa Lobe zapambuyo ndi zofunika mu lamulo la ndondomeko ku mfundo zokhudza thupi la view (izo nkhawa kukula, kubalana ndi mkaka wa m'mawere, nkhawa). nchito imeneyi ikuchitika kuyamika mahomoni ndi peputayidi kuti zinthu ziwalo zolinga: mazira, chiwindi, zopangitsa adrenal, chithokomiro, etc ...

Monga tanenera kale, ulamuliro wa lobes bwino ndi hemispheres lalikulu la ubongo, womwe ndi ubongo imene imalamulira kutentha. amachita mbali ndi kukula timadzi, prolactin, chithokomiro zolimbikitsa timadzi, follicle-popatsana ndi luteinizing timadzi, beta-endorphin.

Zapambuyo Lobe wa pituitary England

gawo tichipeza zigawo zitatu, ndicho osakaniza mantha gawo nyuzi tsinde ndi ukulu apakatikati. Asayansi amanena kuti chinthu ichi ndi ziyerekezo ya ubongo imene imalamulira kutentha Koma ngati pituitary mahomoni monga oxytocin pamene ndi vasopressin, ubongo umabala anati dongosolo. vesicles Neurosecretory ndi mgodi kwa mahomoni awa ndi pansi kuchuluka okwanira iwo anamasulidwa mu magazi.

gawo wogwirizira

Iwo ukufanizidwa ndi wosanjikiza woonda maselo, zomwe zili mbali zina ziwiri. Molingana imeneyi ntchito pa melanocyte-zolimbikitsa timadzi.

ntchito England

Tsopano inu mukhoza kumvetsa bwino zimene ndi pituitary England, mwa kulongosola bwino ntchito zake. Mwachitsanzo, Lobe zapambuyo umabala kwambiri mahomoni mapuloteni. Mankhwala prolactin ndi udindo kupanga chokwanira mkaka mu akazi lactating. Kuonjezera kufunika kukula thupi lathu. Ngati ziri zazing'ono, kukula kwa thupi anaima, ndipo munthu akhoza kukhala nyenyezi yaing'ono. Pamene kwambiri wa timadzi wa n'zotheka kusunga kukula kwambiri.

Thanzi anali mabele England, ndi pituitary England umabala chithokomiro zolimbikitsa timadzi. Ngati kuphwanya zotsatira zake zingakhale aakulu. Pa kotekisi adrenal amakhudza adrenocorticotropic timadzi, ndi chitukuko cha ziwalo zoberekera ndi isanayambike msinkhu zimadalira esitirojeni ndi testosterone - mwamuna ndi mahomoni kugonana mkazi.

Zapambuyo Lobe wa pituitary England kwambiri. Ntchito yake mu chiphunzitso kale anafotokoza mankhwala: oxytocin pamene ndi vasopressin. The timadzi woyamba watenga mbali mu chidule minofu yosalala za m'mimba, ndulu ndi mkodzo. Oxytocin pamene kumapangitsa chidule minofu uterine pa kusiyana mafuko. Komanso, timadzi izi amapangidwa kuti kuchepetsa m'mawere omwe amathandiza kuti zikamera ndi kukula kwa mkaka. mankhwala amathandiza impso kuti tikuona sodium, kupanga mlingo mwazi wake yafupika. Tikumbukenso kuti lobes onse ntchito zawo paokha.

Pituitary England ndi hemispheres oziziritsa ogwirizana ndi mwendo ndi imene mitsempha yaing'ono kuti kupereka chakudya m'thupi. Madokotala amanena kuti si zonse ntchito za iyo ili mokwanira kuliphunzira, ndi kuti kuwonjezera kaphatikizidwe mankhwala, pali mbali ina ya mchitidwe wa. Enieni kuchuluka kwa timadzi apanga sapezeka.

Mavuto ndi pituitary England ndi matenda wotsatira

Uziyenda wabwinobwino wa pituitary England imapereka chitsimikizo cha thanzi la munthu ndi moyo wautali. Thupi - mtundu wa ulamuliro wa thupi polimbana ndi kulamulira bwino wa mahomoni koyenera kuti munthu. A mbali yaikulu mu moyo wathu atenge pituitary England. Ponseponse kawirikawiri chosemphana ndi akhoza kuona zizindikiro zomwe zikuonetsa kuti matenda enieni. Ngakhale kuti amapangidwa ndi mahomoni (kwambiri kapena pang'ono kwambiri), munthu akhoza kukhala ndi lalikulu endocrine matenda kapena matenda.

Kusowa kwa mahomoni ena amakwiya chakuti chithokomiro ntchito, hypothyroidism, kukula kumangidwa, munthu akakhala nyenyezi yaing'ono. Komanso akhoza kukhala hypopituitarism kuti akuzengereza msinkhu mwana kapena kumapangitsa munthu matenda dongosolo ubereki akuluakulu.

ndi overabundance mahomoni ana amakumana ndi mavuto chimodzimodzi aakulu. Pankhaniyi, khalidwe chifuniro matenda monga kuthamanga kwa magazi, shuga, matenda amaganizo ndi ziwalo zoberekera, kuwonjezereka lalikulu (gigantism).

kuyan'anila anapereka - ndi zotsatira za nthenda ntchito kwa pituitary England. Iwo limodzi ndi endocrine ndi kagayidwe kachakudya matenda, chimene chikugwirizana ndi mapangidwe pathological pa malo ena a pituitary thupi. Mu minofu glandular akhoza kupanga mtima wabwino chotupa yakuti "Adenoma". Chifukwa cha matenda angakhale zowonongeka kapena Chigaza, zikubweretsa choipa ubongo kapena neuroinfection.

Pituitary adenoma: chiyani chofunikira?

Mtanda mu mawonekedwe a chotupa kumawonjezera ndi nthawi, kukula kwake amakhala akuluakulu, ndi iwo amayamba kutulutsa kukakamiza minofu glandular imene ili mkati chigaza lapansi. The chizindikiro chachikulu chimakhala endocrine ndi kagayidwe kachakudya matenda, amene anatsagana ndi kusintha Opthalmo-ubongo ndi mkhutu m'thupi bwino.

Madandaulo chachikulu cha odwala kukaonana ndi dokotala ndi: mutu kumene pituitary England, kusintha m'munda zithunzi, kayendedwe mkhutu diso. Matendawa ndi mankhwala a matenda ali ndi makhalidwe komanso ngakhale contraindications kuti zotchulidwa dokotala, malinga ndi chikhalidwe cha matenda. Pankhani ya zotupa zazikulu, ngati palibe contraindications, ntchito alowererepo opaleshoni ndi maphunziro zinachotsedwa.

Ngati munthu wina anakumana microadenomas ndi kukula yaing'ono, zilibe loopsa kwambiri, koma sizikutanthauza kuti mankhwala Sikuti kuchita, monga ukuwonjezeka chotupa, kuchititsa ululu, ndiye komabe kudula izo.

Mitundu ya adenomas pituitary

Gulu la Education anatenga maziko a muyezo kukula. Malinga ndi ichi, pali microadenomas, m'mimba mwake umene ndi masentimita zosakwana awiri, ndipo macroadenoma ndi miyeso kuposa masentimita awiri. Ngati dotolo ali ndi kukayikirana wa matenda, wodwala ayenera kukumana ndi kufufuza matenda ndi chapamwamba kwambiri (chidule monga Kujambula). Izi njira kulola ife kudziwa chikhalidwe cha chotupa cha.

Zabwino matenda chifukwa adzamuika mkulu khalidwe mankhwala. Wodwala adzalandira mankhwala mankhwala zinthu pa inagona pathological.

Mankhwala ndi cheza mankhwala - ndi njira zothandiza kwambiri mankhwala matenda omwe amadziwika yochizira matenda. Lipole ndi munthu kwambiri ndipo zimadalira boma zinchito za thupi la munthu, komanso mmene matenda kumachitika, siteji zimene ya chitukuko.

Kugwiritsa ntchito wailesi yoweyula mankhwala ndi imakhudza pakati pathological, khalidwe la siteji koyamba za matendawa. Ngati chikhalidwe cha adenomas mwapang'onopang'ono, nthawi yomweyo opaleshoni.

Oopsa komanso yosowa kwambiri choncho - pituitary adenoma kuti amapezeka amayi apakati. Mwatsoka, monga microadenomas ankachitira contraindicated, kaya alowererepo pharmacological kapena radiotherapy, monga zotsatira amenewa akhoza kusokoneza mwana wosabadwayo. Chinthu chokha chimene chingakhoze kukhala madokotala - ndi kulamulira matenda. Pamene mayi wabereka mwana, chotupacho mwapang'onopang'ono akhoza kudula. Chifukwa cha zimenezi, anthu odwala ngati kupereka madokotala ananena zawo zabwino.

Pomaliza

Nkhani anapereka zikupereka yankho la funso la chimene ali pituitary England, zomwe amatha iwo ali, chimene kuyan'anila zitheka ndi zimene amatulutsa. Little ting'onoting'ono chidutswa cha thupi, kotoroya kumakhudza yaikulu. Zimenezi zikusonyeza kuti zonse za thupi ndi zofunika ndi zofunika!
