Ngatidzidzei nezvegamba diki riri muuropi hwedu: Posterior Pituitary Gland!

Muviri wedu wakaita semuchina unoshamisa uye wakaoma kunzwisisa, handiti? Tose tinoziva kuti zvese zviri mumuchina uyu zvinodzorwa neuropi hwedu. Asi waiziva here kuti mukati meuropi hwako, mune gland diki sepfupa diki, rinoburitsa mahormone akakosha anodzora huwandu hwemvura mumuviri wako, zvichiita kuti chibereko chivhare panguva yekusununguka, uye kugadzira chisungo ichocho chinoshamisa pakati paamai nemwana? Ndizvo zvatichataura nezvazvo nhasi. Tinodana izvi kuti Gland rePituitary. Nhasi, tichataura zvakadzama nezvechikamu chakakosha charo, Posterior Pituitary.

Kutanga, ngationei, chii chinonzi pituitary gland?

Fungidzira kuti muviri wako ikambani hombe. Ipapo CEO wekambani iyoyo chikamu cheuropi chinonzi hypothalamus. Pasi paCEO uyu pane maneja mukuru. Ndiyo pituitary gland. Maneja uyu akakosha zvikuru, nekuti anodzora mashandiro emamwe magland akawanda mumuviri.

Gland iri repituitary riri pasi pehuropi hwako, kuseri kwemhino yako, munzvimbo yakachengeteka zvikuru. Rakakamurwa kuita zvikamu zviviri. Sepadhesiki rekutambira vanhu muhofisi nekumashure.

1. Anterior Pituitary: Iyi ndiyo nzvimbo yakakura uye ine vanhu vakawanda. Inogadzira nekuburitsa mahormone akawanda ane chekuita nekukura kwemuviri, mashandiro ethyroid, uye mashandiro epabonde.

2. Posterior Pituitary: Uyu ndiye mukuru wedu. Idiki pane anterior pituitary. Haiburitse mahormone, asi inochengeta mahormone maviri akakosha anogadzirwa uye anotumirwa nehypothalamus, uye inoaburitsa muropa kana zvichidikanwa.

Sisitimu inosanganisira magland ese anogadzira mahormone, kusanganisira pituitary gland, inonzi endocrine system . Iyi ndiyo network inotumira mameseji emakemikari mumuviri.

Saka mahormone maviri aya akakosha anoburitswa nePosterior Pituitary chii?

Sezvatakambotaura, Posterior Pituitary yakafanana nenzvimbo yekuchengetera zvinhu. Kune "zvinhu" zviviri zvinokosha zvakachengetwa pano. Mahormone maviri. Ose aya anogadzirwa neHypothalamus. Kana shoko richibva ipapo kuburikidza netsinga, Posterior Pituitary inoburitsa mahormone aya muropa.

Heino tsananguro iri nyore yemahormone maviri aya nebasa rawo.

Fungidzira nguva yaunenge uchidikitira zvakanyanya uye uine nyota. Panguva iyoyo, ropa rako rinokora zvishoma. Hypothalamus iri muuropi inozviziva uye inotumira chiratidzo kuPosterior Pituitary, ichiti, "Zvakanaka, zvino isa ADH muropa." Ipapo ADH inoenda youdza itsvo kuti, "Shandisa mvura zvishoma, usaite weti yakawandisa." Ndipo panobva huwandu hweweti yaunobuda hunoderera, uye ruvara rwayo runobva rwasviba. Kana wava nemvura yakakwana, zvinopesana zvinoitika. Mazinga eADH anoderera, uye mvura yakawandisa inobuda seweti. Hazvisi kudzora kwakanaka here?

Ndezvipi zvirwere zvinogona kusanganiswa nePosterior Pituitary?

Kazhinji, zvirwere zvikuru zvine chekuita negland iri hazviwanzoitiki. Zvisinei, dzimwe nguva, mamwe matambudziko anogona kumuka nekuda kwekubuda kwakanyanya (hypersecretion) kana kusabuda kwakakwana (hyposecretion) kwemahormone aya eADH neoxytocin.

1. Kubuda kweADH muropa zvishoma

Kana kugadzirwa kana kuburitswa kwehomoni yeADH mumuviri kukaderedzwa, itsvo dzinorasikirwa nechiratidzo chekutorazve mvura yadzinoda. Izvi zvinoreva kuti mvura inenge yese yaunonwa inoguma yava muweti yako. Chirwere ichi chinonzi Central Diabetes Insipidus (CDI) .

Dambudziko iri rinogona kukonzerwa nekukuvara kwehypothalamus kana pituitary gland. Dzimwe nguva, hapana chikonzero chingawanikwe.

Zviratidzo zvikuru:

• Weti yakawandisa (Polyuria): Unogona kunwa weti yakawanda pazuva. Ungafanira kuenda kuchimbuzi nguva nenguva.
• Nyota yakawandisa (Polydipsia): Kunyangwe wanwa mvura yakawanda sei, unonzwa sekunge hausi kuwana mvura yakakwana. Muviri wako paunorasikirwa nemvura, uropi hwako hunokuudza kuti urambe uchinwa mvura.
• Kushaya mvura yakakwana mumuviri: Kana ukasanwa mvura yakakwana, unogona kurasikirwa nemvura mumuviri wako.
• Kuneta: Kumuka nguva nenguva husiku kuti uite weti kunogona kukanganisa hope dzako uye kuita kuti unzwe kuneta mukati mezuva rose.

2. Kana homoni yeADH ikawedzera (Hypersecretion yeADH)

Izvi zvakasiyana neyapfuura. Kana paine hormone yeADH yakawandisa mumuviri, itsvo dzinotora mvura yakawandisa mumuviri. Izvi zvinoita kuti weti yakawanda ibude. Izvi zvinoita kuti mvura iungane mumuviri uye sodium (munyu) muropa iderere zvakanyanya. Chirwere ichi chinonzi SIADH (Syndrome of Inappropriate Antidiuretic Hormone Secretion) .

Zvinhu zvinogona kukonzera izvi:

• Mimwe mishonga (semuenzaniso, mimwe mishonga yechirwere cheshuga nepfari).
• Mushure mekuvhiyiwa kwakaitwa pasi peanesthesia.
• Zvirwere zvakaita sekukuvara kweuropi, hutachiona, kana sitiroko.

Zviratidzo zvikuru (izvi zvinowanzokonzerwa nekushomeka kwe sodium muropa):

• Kusvotwa nekurutsa.
• Musoro.
• Kunzwa sekunge uri kurasikirwa nepfungwa dzako uye wava kuda kudonha.
• Kuchinja kwepfungwa kwakadai sekurasikirwa nendangariro uye kusagadzikana.

3. Matambudziko ane chekuita nehomoni yeOxytocin

Kutaura zvazviri, zvirwere zvinokonzerwa nemazinga akaderera kana akakwira ehomoni iyi, oxytocin, hazviwanzoitiki. Idambudziko risingawanzoitiki.

• Kana oxytocin yakaderera: Chibereko chingasanyatsobata zvakanaka panguva yekusununguka, uye mukaka ungasapinda mushure mekunge mwana azvarwa.
• Kana oxytocin ikawedzera: Izvi hazviwanzoitiki. Zvinogona kukonzera kuti tsandanyama dzechibereko dzikure zvakanyanya, zvichiita kuti mwana asati aberekwa aomerwe nekubata.

Unoziva sei kana paine dambudziko nePosterior Pituitary?

Kana uine zviratidzo zvatakambotaura nezvazvo, chiremba wako achatanga akubvunza nezvezviratidzo zvako. Zvadaro, vanogona kuita bvunzo kuti vawane mufananidzo chaiwo wemazinga emahormone ako.

• Kuongororwa kweRopa: Zvinhu zvakaita semazinga eADH hormone uye mazinga e sodium muropa zvinogona kuyerwa.
• Kuongororwa kweweti: Unogona kuona kuti weti yako yakakora kana kuti yakatetepa sei.
• MRI scan: Izvi zvinobatsira kutarisa bundu kana kukuvara kwepituitary gland kana hypothalamus.

Chiremba wako ndiye achasarudza marapirwo zvichienderana nemigumisiro yebvunzo idzi.

Ndinofanira kuona chiremba rini?

Zvizhinji zvezvirwere zvatakurukura hazviwanzoitiki. Zvisinei, kana ukaona shanduko mumuviri wako, zvakanaka kuti usazviregeredza.

Zvikuru sei, kana uine chimwe chezviratidzo zvinotevera kana kupfuura, usapedza nguva woenda kuna chiremba wako.

• Kana uine nyota isingafungidzike uye uchiita weti yakawandisa kakawanda .
• Kana uchinzwa kuda kurutsa, kurutsa, musoro, uye kunzwa kusagadzikana pasina chikonzero.
• Kana ukangoerekana wanzwa sekunge ndangariro yako yavhiringika uye haugone kuisa pfungwa dzako pachinhu chimwe chete .

Panguva dzakadai, kuona chiremba uye kuongororwa zviri nyore kunogona kukubatsira kuona kana paine dambudziko kana kwete. Saka usatya kutsvaga rubatsiro rwechiremba.
