IiHormones ze hypothalamus

I-Hypothalamus yenye yezona ziko ezisemgangathweni kwinkqubo ye-endocrine yabantu. Kufumaneka kufuphi nesiseko sobuchopho. Unoxanduva lokusebenza ngokufanelekileyo kwegciwane le-pituitary kunye ne-metabolism evamile. IiHormones eziveliswe kwi-hypothalamus zibaluleke kakhulu kumzimba. Ziyi-peptides ezijongene neenkqubo ezahlukeneyo ezenzeka emzimbeni.

Ziziphi i-hormones eziveliswa yi-hypothalamus?

Kwi-hypothalamus kukho iiseli zesisindo, ezijongene nokuveliswa kwazo zonke i-hormone ezibalulekileyo. Zibizwa ngokuba ngama-neurosecretory cells. Ngomzuzwana othile, bafumana iimpembelelo ezinomdla, ezihanjiswa yiinkalo ezahlukeneyo zesistim. I-axx ye-neurosecretory cells iphelisa imithana yegazi, apho i-axo-vasal synapses ifom. Ngokugqibela kunye nama-hormone akhiqizwayo akhutshwa.

I-hypothalamus ivelisa ama-liberin kunye nama-statins-oko kuthiwa ukukhulula ama-hormone. Ezi zinto zifunekayo ukulawula umsebenzi we-hormonal we-pituitary gland. Izitatimende zinoxanduva lokunciphisa ukuhlanganiswa kwezinto ezizimeleyo, kunye namaLiberia ngokunyusa.

Kuza kube yimhla, i-hormone ezifunyenwe kakuhle ze hypothalamus:

1. Gonadoliberines. Ezi hormone zinoxanduva lokunyusa inani lama-hormone ezesondo ezivelisiweyo. Baye bathatha inxaxheba kwinkxaso yesiqhelo sokuya esikhathini kunye nokwakhiwa kwesifiso sesini. Ngaphantsi kwefuthe lemali enkulu ye-lyuliberin - enye yeentlobo ze-gonadotypes-amaqabunga eqanda elivuthiweyo. Ukuba la ma hormone akwanele, umfazi unokuhlakulela intswela .
2. Somatoliberin. La mahomoni, aveliswa yi-hypothalamus, ayadingeka ukukhulula izinto zokukhula. Kumele ukuba ziphuhliswe kakhulu ebuntwaneni nasebuncinaneni. Kwimeko yokuntuleka kwehomoni, i-dwarfism iyakhula.
3. Corticoliberin. Uxanduva lokuvelisa kakhulu i-horrenone ye-adrenocorticotropic kwi-pituitary gland. Ukuba i-hormone ayivelwanga kwimali efunekayo, kwiimeko ezininzi ukungakwazi ukuzaliswa kwamanzi.
4. Prolactoliberin. Le nkunkuma ibandakanyeke ngokukhethekileyo kufuneka iphuhlise ngexesha lokukhulelwa kunye nexesha lokukhulelwa. Isiphumo sokukhululwa sandisa inani leprolactin elivelise kwaye likhuthaza ukuphuhliswa kwamathanga ebantwini.
5. I-Dopamine, i-melanostatin kunye ne-somatostatin. Bawuthintela ama-hormone eTroyikhi akhiqizwa kwi-gland gland.
6. Melanoliberin. Uthatha inxaxheba kwimveliso ye-melanin kunye nokuveliswa kweeseli ze-pigment.
7. ITyroliberin. Kubalulekile ukuhlukanisa i-hormone ye-thyroid-stimulating and increase thyroxine egazini.

Ummiselo we-secretion ye-hormone ye-hypothalamus

Inkqubo yesifo iyasabela kwimimiselo ye-hormone secretion. Amahomoni amaninzi ekujoliswe kuyo i-gland ishicilelo, ukuvimba okuncinci kwama-hormone eTropiki. Olu lwalamano alukwazi nje ukuthobhisa. Kwezinye iimeko, utshintshe umphumo wamahomoni e-hypothalamus kwiiseli ezisegulini.

Iirmone imithi ye hypothalamus

Ezi ziquka:

1. Sermorelin. Umfanekiselo we-hormone yokukhula kwemvelo. Inikwe ikakhulu abantwana abancinci kakhulu. Akunqunywanga ngexesha lokukhulelwa kunye ngexesha lokukhulelwa.
2. Bromocriptine. Zasetyenziselwa ukukhuthaza i-postsynaptic receptors ye-dopamine. Inqunywe ukuphazamiseka kocando.
3. Okreotid. Inokunciphisa imveliso ye-hormone yokukhula kunye nokuphelisa umsebenzi wee-tissue tissues. Inqunywe izilonda kunye nezikhumba ezifihlayo.
4. Rifatiroin. Isifaniso se-hormone ye hypothalamus ye-tiropropin.
5. Stylamine. Inganciphisa ukuhamba kwegazi kwizitho zangaphakathi, ngaphandle kokuphazamisa uxinzelelo lwegazi lwenkqubo.
