Cia peb kawm txog lub qog pituitary posterior xwb.

Koj puas tau xav tias muaj pes tsawg feem me me ntawm peb lub cev ua haujlwm ntau ua luaj? Hnub no peb yuav tham txog ib lub qog me me uas ua ntau yam zoo kawg nkaus. Nws hu ua lub qog pituitary. Tshwj xeeb, peb yuav tsom mus rau sab nraub qaum ntawm lub qog ntawd, "Posterior Pituitary"

Lub qog pituitary no yog dab tsi? Dab tsi tshwj xeeb txog sab nraub qaum?

Hais yooj yim xwb, lub qog pituitary yog ib lub qog me me, loj li taum pauv nyob rau hauv qab ntawm peb lub hlwb, hauv qab hypothalamus. Nws yog ib feem tseem ceeb heev ntawm peb lub endocrine system. Xav txog, txawm tias nws me me, nws tswj ntau cov tshuaj hormones tseem ceeb tshaj plaws hauv peb lub cev.

Muaj ob feem tseem ceeb ntawm lub qog pituitary no:

1. Lub plawv pem hauv ntej

2. Posterior Lobe - Qhov no yog qhov peb tab tom tham txog hnub no, "Posterior Pituitary".

Lub qog pituitary tsim thiab tso tawm ntau yam tshuaj hormones. Txawm li cas los xij, lub qog pituitary posterior yog qhov tshwj xeeb. Nws khaws thiab tso tawm tsuas yog ob qho ntawm cov tshuaj hormones uas lub qog pituitary tsim tawm thaum xav tau. Ob qho tshuaj hormones no yog:

• Oxytocin
• Tshuaj Antidiuretic Hormone (ADH), tseem hu ua Vasopressin.

Tam sim no tej zaum koj yuav xav tias, "Yog li lub hypothalamus no yog dab tsi?" Lub hypothalamus kuj yog ib feem ntawm peb lub hlwb. Nws tswj ntau yam, suav nrog ntshav siab, lub plawv dhia, qhov kub ntawm lub cev, thiab kev zom zaub mov. Qhov xav tsis thoob, lub qog pituitary txuas nrog hypothalamus los ntawm ib ceg me me. Qhov no hu ua ceg pituitary. Nws yog los ntawm ceg no uas hypothalamus qhia rau lub qog pituitary, "Okay, tso cov tshuaj hormones ntawd tam sim no."

Lub Endocrine System yog dab tsi? Thov piav qhia me ntsis.

Lo lus nug zoo heev! Lub cev endocrine yog ib lub network ntawm cov qog hauv peb lub cev uas tsim cov tshuaj hu ua cov tshuaj hormones thiab tso tawm ncaj qha mus rau hauv cov ntshav.

Cov tshuaj hormones zoo li cov neeg xa xov uas nqa cov lus hauv peb lub cev. Lawv mus ncig los ntawm cov ntshav thiab qhia peb cov kabmob, daim tawv nqaij, cov leeg, thiab lwm yam nqaij yuav tsum ua li cas thiab thaum twg yuav tsum ua.

Cov qog thiab cov kab mob tseem ceeb uas ua rau peb lub cev endocrine system yog:

• Hypothalamus
• Cov qog pituitary
• Cov qog thyroid '(Thyroid)'
• Cov qog parathyroid
• Cov qog adrenal
• Cov qog pineal
• Pancreas
• Cov zes qe menyuam (rau cov poj niam)
• Cov noob qes (cov noob qes) (txiv neej)

Cov tshuaj hormones twg uas lub qog pituitary tom qab tso tawm? Lawv ua haujlwm dab tsi?

Raws li peb tau hais ua ntej lawm, lub qog pituitary sab tom qab khaws thiab tso tawm ob hom tshuaj hormones tseem ceeb. Cov tshuaj hormones no yog tsim los ntawm hypothalamus. Tab sis lawv raug khaws thiab tso tawm thaum lub qog pituitary sab tom qab xav tau.

1. Tshuaj Antidiuretic Hormone (ADH) los yog Vasopressin:

• Cov tshuaj hormones no tseem ceeb heev. Nws yog cov tshuaj hormones no uas pab lub cev nqus cov dej kom txaus thaum peb lub raum lim cov ntshav. Hais yooj yim, ADH pab tswj qhov sib npaug ntawm cov dej hauv peb lub cev.

2. Oxytocin:

• Rau cov poj niam, nws pab txhawb kev yug menyuam los ntawm kev ua rau lub tsev menyuam nruj thaum lub sijhawm yug menyuam. Nws kuj tseem ua rau cov mis tsim mis. Oxytocin kuj tseem cuam tshuam rau kev sib raug zoo ntawm niam thiab menyuam.
• Rau cov txiv neej, cov tshuaj hormones no kuj tseem tuaj yeem cuam tshuam rau kev sib raug zoo ntawm cov niam txiv thiab cov menyuam. Tsis yog li ntawd xwb, tab sis oxytocin kuj tseem pab thawb cov phev thiab cov kua phev mus tom ntej thaum lub sijhawm ejaculation.

Yog li ntawd, lub luag haujlwm tseem ceeb ntawm lub posterior pituitary yog dab tsi?

Qhov tseem ceeb tshaj plaws yog khaws cov oxytocin thiab antidiuretic hormone (ADH) thiab tso tawm thaum lub teeb liab los ntawm hypothalamus. Lub hypothalamus xa cov teeb liab no los ntawm cov hlab ntsha uas los ntawm lub pituitary stalk uas peb tau tham txog ua ntej.

Posterior Pituitary txuas nrog lwm cov kabmob li cas?

Qhov no yog ib zaj dab neeg nthuav heev. Lub posterior pituitary txuas ncaj qha rau hypothalamus. Vim tias hypothalamus ua oxytocin thiab ADH thiab qhia rau lawv thaum twg yuav tsum tso lawv tawm.

Ntxiv rau:

• Oxytocin ua haujlwm nrog lub tsev menyuam, cov qog mis (mis), thiab cov vas deferens hauv cov txiv neej.
• ADH (antidiuretic hormone) ua haujlwm feem ntau nrog peb lub raum.

Lub qog pituitary sab nraub qaum nyob qhov twg? Nws loj npaum li cas?

Lub qog pituitary nyob ntawm lub hauv paus ntawm peb lub hlwb, tom qab lub choj ntawm peb lub qhov ntswg, hauv qab hypothalamus. Nws nyob hauv ib qho chaw me me hauv pob txha sphenoid. Qhov no hu ua Sella Turcica.

Tag nrho cov qog pituitary yog li ntawm qhov loj ntawm taum pauv, li ntawm 1/3 ntawm ib nti. Cov qog pituitary posterior yog ib feem ntawm cov qog uas tig mus rau sab nraub qaum. Nws me dua li cov qog pituitary pem hauv ntej. Cov qog pituitary pem hauv ntej suav txog li 80% ntawm qhov hnyav ntawm tag nrho cov qog pituitary.

Cov kab mob thiab tej yam mob uas feem ntau muaj feem cuam tshuam nrog Posterior Pituitary yog dab tsi?

Cov teeb meem tseem ceeb uas tuaj yeem tshwm sim nrog lub posterior pituitary yog hypersecretion lossis hyposecretion ntawm oxytocin lossis antidiuretic hormone (ADH).

Feem ntau ntawm cov mob no tsis tshua muaj. Tsis tas li ntawd, cov qog nqaij hlav tuaj yeem cuam tshuam rau lub qog pituitary tom qab, tab sis lawv kuj tsis tshua muaj. Cov qog nqaij hlav pituitary feem ntau tshwm sim hauv lub qog pituitary pem hauv ntej.

Kev tso tawm ntawm cov tshuaj hormones antidiuretic (ADH) tsis txaus

Qhov no yog tshwm sim los ntawm kev txo qis ntawm kev tsim cov ADH hauv hypothalamus lossis kev txo qis ntawm kev tso tawm ntawm ADH los ntawm lub qog pituitary. Qhov no feem ntau yog tshwm sim los ntawm kev puas tsuaj rau hypothalamus lossis posterior pituitary. Qee zaum nws kuj tuaj yeem tshwm sim los ntawm kev hloov pauv ntawm cov noob caj noob ces. Hauv qee kis, qhov ua rau tsis paub.

Thaum cov qib ADH qis dua li qub, lub raum tsis tuaj yeem nqus dej ntau npaum li lawv xav tau. Qhov no ua rau muaj dej ntau dua tawm hauv cov zis (cov zis yuav yaj), txo cov dej hauv cov ntshav thiab ua rau nws cov concentration ntau dua.

Yog tias ADH tsis txaus, ces yuav ua rau muaj teeb meem tsis tshua muaj neeg paub txog kev hloov pauv dej hu ua "Central Diabetes Insipidus - CDI". Qhov no yuav tsum tsis txhob yuam kev nrog "Diabetes Mellitus", vim ob yam no txawv kiag li. CDI tuaj yeem ua rau tuag taus yog tias tsis kho kom zoo.

Cov tsos mob ntawm CDI yog:

• Kev tso zis ntau zaus (Polyuria)
• Kev nqhis dej ntau dhau (Polydipsia)
• Qaug zog (yuav tsum sawv ntau zaus thaum hmo ntuj mus tso zis)
• Kev qhuav dej

Kev tso tawm ntau dhau ntawm cov tshuaj antidiuretic (ADH)

Qhov no yog tshwm sim los ntawm kev tsim ADH ntau ntxiv hauv hypothalamus lossis kev tso ADH ntau ntxiv los ntawm posterior pituitary. Qhov mob no hu ua '(Syndrome of Inappropriate Antidiuretic Hormone secretion - SIADH)'. Thaum ADH ntau ntxiv, lub cev khaws dej ntau dhau. Tom qab ntawd cov zis yuav ua rau muaj ntau heev, thiab cov ntshav yuav ua rau muaj dej ntau dua thiab yaj.

Muaj ntau yam ua rau SIADH thiab ADH theem siab dua. Qee yam ua rau muaj xws li:

• Qee cov tshuaj (piv txwv li, qee cov tshuaj rau hom ntshav qab zib 2, cov tshuaj rau qaug dab peg)
• Kev phais mob ua raws li kev siv tshuaj loog dav dav
• Cov teeb meem ntawm lub hlwb (kev raug mob, kev kis kab mob, mob stroke)
• Kev phais hlwb uas cuam tshuam nrog hypothalamus

Cov tsos mob ntawm cov ADH ntau ntxiv feem ntau yog los ntawm cov ntshav sodium qis. Cov tsos mob ntawm cov ntshav sodium qis muaj xws li:

• Xeev siab thiab ntuav
• Mob taub hau (mob taub hau)
• Kev poob ntawm qhov sib npaug (tej zaum yuav poob)
• Kev hloov pauv ntawm lub hlwb (kev tsis meej pem, kev nco tsis zoo)

Kev txo qis ntawm Oxytocin

Qhov no yog ib qho xwm txheej tsis tshua muaj.Thaum cov tshuaj oxytocin poob qis dua li qub, lub tsev menyuam tsis txav thiab mis tsis tawm thaum lub sijhawm yug menyuam. Txawm hais tias tsis tshua muaj, qhov ua rau qhov no feem ntau yog mob hu ua "Panhypopituitarism." Qhov no yog thaum cov tshuaj hormones hauv lub qog pituitary qis dua li qub.

Kev tso zis ntau dhau ntawm Oxytocin

Qhov no kuj tsis tshua muaj. Qhov no hu ua oxytocin lom. Thaum cov oxytocin ntau dua li qub, lub tsev menyuam yuav ua haujlwm ntau dhau. Cov leeg nqaij hauv tsev menyuam yuav nce ntxiv (hypertrophy), thiab tsis muaj chaw txaus rau tus menyuam hauv tsev menyuam, uas tuaj yeem txwv tsis pub cev xeeb tub.

Puas muaj kev kuaj mob twg uas tuaj yeem kuaj xyuas kev noj qab haus huv ntawm kuv lub qog pituitary posterior?

Yog tias koj muaj cov tsos mob ntsig txog teeb meem nrog lub qog pituitary posterior, koj tus kws kho mob yuav hais kom kuaj ADH thiab / lossis oxytocin.

• Kev kuaj ntshav ADH tuaj yeem pab txheeb xyuas qhov tsis txaus lossis ntau dhau ntawm ADH thiab nrhiav qhov ua rau.
• Koj cov qib oxytocin tuaj yeem kuaj tau hauv ntau yam kua dej, xws li cov qaub ncaug, ntshav, plasma, zis, thiab cov kua dej hauv lub hlwb.

Yog tias cov txiaj ntsig ntawm kev kuaj mob tsis zoo li qub, koj tus kws kho mob yuav hais kom koj ua qhov kev kuaj duab xws li MRI (Magnetic Resonance Imaging), los saib koj lub qog pituitary.

Kuv yuav tsum mus ntsib kws kho mob thaum twg?

Yog koj muaj cov tsos mob ntawm '(Central Diabetes Insipidus - CDI)' lossis '(Syndrome of Inappropriate Antidiuretic Hormone secretion - SIADH)', nco ntsoov mus ntsib koj tus kws kho mob.

Nco ntsoov tias, feem ntau cov teeb meem kev noj qab haus huv uas cuam tshuam nrog cov kab mob posterior pituitary tsis tshua muaj. Tab sis yog tias koj muaj cov tsos mob tshiab lossis ua rau txhawj xeeb, nws yog qhov zoo tshaj plaws los tham nrog kws kho mob. Lawv tuaj yeem khiav ob peb qhov kev kuaj yooj yim los xyuas koj txoj kev noj qab haus huv.

Cov lus tseem ceeb tshaj plaws uas yuav tsum nco ntsoov los ntawm qhov peb tau tham txog (Cov Lus Coj Mus Tsev)

Zoo, yog li kuv vam tias koj tam sim no nkag siab zoo txog qhov me me tab sis tseem ceeb heev no hu ua "Posterior Pituitary" uas peb tau tham txog hnub no. Hais yooj yim:

• Lub posterior pituitary yog qhov tom qab ntawm lub qog pituitary hauv peb lub hlwb.
• Nws feem ntau khaws thiab tso tawm ob hom tshuaj hormones hu ua oxytocin thiab antidiuretic hormone (ADH). Cov tshuaj hormones no yog tsim los ntawm hypothalamus.
• ADH pab tswj qhov sib npaug ntawm cov dej hauv peb lub cev .
• Oxytocin tseem ceeb rau kev yug menyuam, kev pub niam mis, thiab kev sib raug zoo ntawm tib neeg .
• Kev hloov pauv ntawm cov tshuaj hormones no tuaj yeem ua rau muaj teeb meem kev noj qab haus huv (txawm tias tsis tshua muaj) xws li "Central Diabetes Insipidus - CDI" thiab "SIADH"
• Yog koj muaj tej yam tsos mob txawv txawv, ces koj yuav tsum nrhiav kev pab kho mob.

Peb lub cev yeej zoo kawg nkaus li, puas yog? Zoo kawg nkaus li thaum xav txog tias ib feem me me no ua tau ntau yam haujlwm!

Cov tshuaj hormones, oxytocin, antidiuretic hormone, ADH, endocrine system, thiab lwm yam.
