Ngatingodzidzai nezve posterior pituitary gland.

Wakambozvibvunza here kuti nhengo diki diki dzemuviri wedu dzinoshanda zvakanyanya kudaro? Nhasi tichataura nezve gland diki kwazvo rinoita zvinhu zvakawanda zvinoshamisa. Rinonzi gland re pituitary. Zvikuru, tichatarisa chikamu chekumashure che gland iroro, "Posterior Pituitary".

Chii chinonzi pituitary gland iyi? Chii chakakosha pamusoro pemusana?

Zvichitaurwa zviri nyore, pituitary gland igondo diki rakakura sepizi, riri pasi pehuropi hwedu, pasi pehypothalamus. Iro chikamu chakakosha kwazvo chehurongwa hwedu hwe endocrine. Fungidzira, kunyangwe riri diki, rinodzora mahormone mazhinji akakosha mumuviri wedu.

Kune zvikamu zviviri zvikuru zvegland iyi yepituitary:

1. Lobe Yepamberi

2. Posterior Lobe - Izvi ndizvo zvatiri kutaura nezvazvo nhasi, ``Posterior Pituitary``.

Gland repituitary rinoburitsa nekuburitsa mahormone akati wandei. Zvisinei, gondo repituitary repashure rakakosha. Rinochengeta nekuburitsa mahormone maviri chete anogadzirwa negondo repituitary kana zvichidikanwa. Mahormone maviri aya ndeaya:

• Oxytocin
• Hormone inorwisa diuretic (ADH), inonziwo Vasopressin.

Zvino ungave uchifunga kuti, "Saka iyi hypothalamus chii?" Hypothalamus chikamu chehuropi hwedu. Inodzora zvinhu zvakawanda, zvinosanganisira BP, kurova kwemoyo, tembiricha yemuviri, uye kugaya. Zvinoshamisa kuti pituitary gland yakabatana nehypothalamus nedzinde diki. Izvi zvinonzi pituitary gadzi. Ndiko kuburikidza nedzinde iri apo hypothalamus inoudza pituitary gland kuti, "Zvakanaka, buritsa hormone iyoyo izvozvi."

Chii chinonzi Endocrine System? Ndapota tsanangura zvishoma.

Mubvunzo wakanaka! Sisitimu yeendocrine isangano remagland mumuviri wedu rinogadzira makemikari anonzi mahormone uye rinoaburitsa zvakananga muropa.

Mahormone akafanana nevatumwa vanotumira mashoko mumiviri yedu. Anofamba nemuropa oudza nhengo dzedu, ganda, tsandanyama, nedzimwe nyama zvekuita uye nguva yekuzviita.

Matumbu makuru nenhengo dzinoumba sisitimu yedu ye endocrine ndeaya:

• Hypothalamus
• Gland rePituitary
• Gland reThyroid `(Thyroid)`
• Matumbu eParathyroid
• Matumbu eAdrenal
• Gland repaini
• Pancreas
• Mazai (muvakadzi)
• Machende (machende) (echirume)

Mahormone api anoburitswa ne posterior pituitary gland? Anoitei?

Sezvatakambotaura, posterior pituitary gland inochengeta nekuburitsa mhando mbiri huru dzemahormone. Mahormone aya anogadzirwa nehypothalamus. Asi anochengetwa uye anoburitswa kana achidikanwa neposterior pituitary gland.

1. Homoni Inoderedza Kubuda Kwemvura Mudumbu (ADH) kana Vasopressin:

• Hormone iyi inokosha zvikuru. Ndiyo homoni iyi inobatsira muviri kunwisa mvura inodiwa kana itsvo dzedu dzichisefa ropa. Zvichitaurwa zviri nyore, ADH inobatsira kudzora kuenzana kwemvura mumuviri wedu.

2. Oxytocin:

• Kuvakadzi, inobatsira pakusununguka nekuita kuti chibereko chigumbuke panguva yekusununguka. Inokurudzirawo mazamu kuti abudise mukaka. Oxytocin inokanganisawo hukama pakati paamai nemwana.
• Muvarume, hormone iyi inogonawo kukanganisa hukama pakati pevabereki nevana. Kwete izvozvo chete, asi oxytocin inobatsirawo kusundira mbeu yemurume nembeu mberi panguva yekubuda kwembeu.

Saka chii chinonyanya kushanda ne posterior pituitary?

Chinhu chikuru ndechekuchengeta oxytocin ne antidiuretic hormone (ADH) uye kuzviburitsa kana chiratidzo chabuda kubva ku hypothalamus. Hypothalamus inotumira zviratidzo izvi kuburikidza netsinga dzinouya kuburikidza ne pituitary stem yatakambotaura nezvayo.

Posterior Pituitary yakabatana sei nedzimwe nhengo dzemuviri?

Iyi inyaya inonakidza zvikuru. Pituitary yekumashure yakabatana zvakananga nehypothalamus. Nekuti hypothalamus inogadzira oxytocin neADH uye inovaudza nguva yekuiburitsa.

Pamusoro pe:

• Oxytocin inoshanda nechibereko, mazamu (mazamu), uye vas deferens muvarume.
• ADH (hormone inodzivirira diuretic) inoshanda zvakanyanya neitsvo dzedu.

Pituitary yekumashure iri kupi? Yakakura sei?

Gland repituitary riri pasi pehuropi hwedu, seri kwebhiriji remhino dzedu, pasi chaipo pehypothalamus. Riri mugomba diki mupfupa resphenoid. Izvi zvinonzi Sella Turcica.

Gland rese repituitary rakakura sepizi, rinenge 1/3 ye inchi. Gland rekumashure repituitary chikamu chegland chakatarisana nekumashure. Chidiki pane chepituitary yekumberi. Gland rekumberi rinoita 80% yehuremu hwegland rese repituitary.

Ndezvipi zvirwere nezvirwere zvakajairika zvine chekuita nePostterior Pituitary?

Matambudziko makuru anogona kuitika ne posterior pituitary ndeye hypersecretion kana hyposecretion ye oxytocin kana antidiuretic hormone (ADH).

Zvizhinji zvezvirwere izvi hazviwanzoitiki. Zvakare, bundu rinogona kukanganisa posterior pituitary gland, asi hazviwanzoitikiwo. Bundu repituitary rinowanzo buda mu anterior pituitary gland.

Kubviswa kwehomoni inoderedza diuretic (ADH) muropa

Izvi zvinokonzerwa nekudzikira kwekugadzirwa kweADH mu hypothalamus kana kudzikira kwekuburitswa kweADH kubva mugland repituitary. Izvi zvinowanzokonzerwa nekukuvara kwehypothalamus kana posterior pituitary. Dzimwe nguva zvinogonawo kukonzerwa nekuchinja kwemajini. Mune zvimwe zviitiko, chikonzero hachizivikanwe.

Kana huwandu hweADH hwakaderera pane hwakajairwa, itsvo hadzikwanisi kunwa mvura yakawanda sezvadzinoda. Izvi zvinoita kuti mvura yakawanda ibude muweti (weti inova shoma), zvichideredza huwandu hwemvura muropa uye zvichiwedzera kuwanda kwayo.

Kushaikwa kweADH kunogona kukonzera chirwere chisingawanzoitika mumuviri chinonzi ``Central Diabetes Insipidus - CDI''. Izvi hazvifanirwe kuvhiringidzwa ne ``Diabetes Mellitus'', sezvo zviviri izvi zvakasiyana zvachose. CDI inogona kuisa hupenyu panjodzi kana ikasarapwa zvakanaka.

Zviratidzo zveCDI ndeizvi:

• Kuita weti kakawanda `(Polyuria)`
• Nyota yakawandisa (Polydipsia)
• Kuneta (kumuka kakawanda husiku kuti uite weti)
• Kushaya mvura mumuviri

Kubuda kwakanyanya kwehomoni inorwisa diuretic (ADH)

Izvi zvinokonzerwa nekuwedzera kwekugadzirwa kweADH mu hypothalamus kana kuwedzera kwekuburitswa kweADH kubva mu posterior pituitary. Dambudziko iri rinonzi `(Syndrome of Inappropriate Antidiuretic Hormone secretion - SIADH)`. Kana huwandu hweADH hukawedzera, muviri unochengeta mvura yakawandisa. Ipapo weti inova yakawanda, uye ropa rinova mvura yakawanda uye rinoderera.

Pane zvikonzero zvakawanda zvinoita kuti huwandu hweSIADH neADH huwedzere. Zvimwe zvezvikonzero zvinowanzoonekwa zvinosanganisira:

• Mimwe mishonga (semuenzaniso, mimwe mishonga yechirwere cheshuga cherudzi rwechipiri, mishonga yepfari)
• Kuvhiyiwa kunoitwa pasi peanesthesia
• Matambudziko epfungwa (kukuvara, hutachiona, sitiroko)
• Kuvhiyiwa kwehuropi kunosanganisira hypothalamus

Zviratidzo zvekuwedzera kwemazinga eADH zvinowanzokonzerwa nekushomeka kwe sodium muropa. Zviratidzo zvekushomeka kwe sodium muropa zvinosanganisira:

• Kusvotwa nekurutsa
• Musoro (musoro)
• Kurasikirwa nekudzikama (zvichida kudonha)
• Kuchinja kwepfungwa (kuvhiringidzika, kurasikirwa nendangariro)

Kubviswa kweOxytocin muropa

Iyi inyaya isingawanzoitiki.Kana huwandu hweoxytocin hukadzikira pasi pehunhu hwemuviri, chibereko chinomira kugwinha uye mukaka unodzikira panguva yekusununguka. Kunyangwe zvisingawanzoitiki, chikonzero chikuru cheizvi chirwere chinonzi "Panhypopituitarism." Apa ndipo apo huwandu hwemahormone ese ari mugland repituitary hunenge hwakaderera pane hwakajairwa.

Kubuda kweOxytocin zvakanyanya

Izvi hazviwanzoitiki. Izvi zvinonzi oxytocin toxicity. Kana huwandu hwe oxytocin hwakwira kupfuura zvakajairika, chibereko chinotanga kushanda zvakanyanya. Tsandanyama dzechibereko dzinowedzera (hypertrophy), uye hapana nzvimbo yakakwana yemwana ari muchibereko, izvo zvinogona kuderedza kubata pamuviri.

Pane here bvunzo dzinogona kuongorora hutano hwe posterior pituitary gland yangu?

Kana uine zviratidzo zvine chekuita nematambudziko e posterior pituitary gland, chiremba wako anogona kuraira kuti uongorore mazinga eADH uye/kana oxytocin.

• Kuongororwa kweropa reADH kunogona kubatsira kuona kushomeka kweADH kana kuti yakawandisa uye kuwana chikonzero.
• Huwandu hweoxytocin mumuviri wako hunogona kuyedzwa mumvura dzakasiyana-siyana, dzakadai semate, ropa, plasma, weti, uye cerebrospinal fluid.

Kana mhedzisiro yebvunzo isiri yemazuva ese, chiremba wako anogona kukurudzira kuti utore bvunzo yemifananidzo, senge MRI (Magnetic Resonance Imaging), kuti utarise pituitary gland yako.

Ndinofanira kuona chiremba rini?

Kana uine zviratidzo zve `(Central Diabetes Insipidus - CDI)` kana `(Syndrome of Inappropriate Antidiuretic Hormone secretion - SIADH)`, iva nechokwadi chekuona chiremba wako.

Yeuka kuti matambudziko mazhinji ehutano ane chekuita nezvirwere zveposterior pituitary haawanzoitiki. Asi kana uine zviratidzo zvitsva kana zvinokunetsa, zvakanaka kutaura nachiremba. Vanogona kuita bvunzo shoma kuti vaongorore hutano hwako.

Zvinhu zvakakosha zvekurangarira kubva pane zvatataura nezvazvo (Mharidzo Yekuenda Kumba)

Zvakanaka, saka ndinovimba kuti ikozvino mava kunzwisisa zvakanaka chikamu ichi chidiki asi chakakosha chinonzi ``Posterior Pituitary'' chatataura nezvacho nhasi. Zvichitaurwa zviri nyore:

• Pituitary yekumashure chikamu chekumashure chegland repituitary muuropi hwedu.
• Inonyanya kuchengeta nekuburitsa mahormone maviri anonzi oxytocin uye antidiuretic hormone (ADH). Mahormone aya anogadzirwa nehypothalamus.
• ADH inobatsira kudzora mwero wemvura mumuviri wedu .
• Oxytocin inokosha pakusununguka, kuyamwisa, uye kubatana kwevanhu .
• Kuchinja-chinja kwemahormone aya kunogona kukonzera matambudziko ehutano (kunyange zvisingawanzoitiki) akadai se "Central Diabetes Insipidus - CDI" uye "SIADH".
• Kana uine zviratidzo zvisingawanzoitiki, kuchenjera kutsvaga rubatsiro rwechiremba.

Miviri yedu inoshamisa zvechokwadi, handiti? Zvinoshamisa kufunga kuti basa rakawanda sei rinogona kuitwa nechikamu chidiki chakadaro!
