Thyroid-anotokonya kemikari: kondakita muviri

The kukosha uye kukosha thyroid kemikari anozivikanwa vose, nekuti vakanga kumutsa yedu muviri chamatare, kuva kunokosha nokuda rinopindirana kukura kwomuviri uye kubudirira kwebasa chepfungwa. Zvisinei, haasi munhu wose anoziva kuti basa thyroid shwanu inotongwa kemikari zviri ropa, iro tinoti thyroid-mutange kemikari. Kugadzirwa Its anogadzirwa yomukati sanctum uropi - duku muviri uremu mu hafu giremu, unonzi pituitary shwanu.

Zvisinei, kuti pituitary shwanu - kwete chinonyanya kukosha, "mukuru webasa", iyo inodzora thyroid chaitika. It inotongwa hypothalamus, unobereka thyrotropin-kusunungura kemikari. Kuwedzera kune zvakananga mirairo "Vakuru" kusvika pituitary shwanu anokosha chaizvo unongotaura. Saka, kana vakaona kuti ropa iri thyroid yakawandisa kemikari, kuti pituitary rinomira basa rayo. Kana vari, nekusiyana, hazvina kukwana, ari secretion kuti thyroid-anotokonya kemikari inowedzerawo. Izvi anonzi musimboti inofambiswa, mashandiro uyu murau zvakajairika chaizvo pezvakaitwa zvose zviri mumuviri womunhu.

Thyroid anotokonya kemikari pamusoro ndeyokuva kuchengetwa dzimwe nguva. Very kashoma hwakabatana pamwe mabasa "Chief" pakukura - the hypothalamus uye dzimwe nguva bundu anogona kumutsa ezvinhu apo haana sei zviratidzo vawedzere ropa thyroid mahormone. Dzimwe nguva, nyaya yose pituitary chirwere. Asi akawanda thyroid-anotokonya kemikari pamwero parinobuda nokuti kuti pane mhirizhonga iri ufanane thyroid shwanu uye haisi rakagadzirirwa kutsungirira basa rake. Zvadaro pane yakapinza kuwedzera kugadzirwa thyroid anotokonya kemikari ari pituitary pasina kuedza angambosvika kuwedzera padanho thyroid mahormone. Uyewo, zvishomanana kuwedzera kwevari kemikari pasi kufunga zviri pasika mukuru mupfungwa kana mumuviri kunoda kuunganidza mauto ose saka thyroid shwanu ari kushanda pane zvizere chinzvimbo, uye pituitary aikanganiswa thyroid kemikari ipfupi. Pose chiremba anoona kuwedzera thyroid anotokonya kemikari kupfuura dzose, zviri kutyisa nokuti chiratidzo ichi kunogona kuva zvose chikonzero uye mugumisiro chirwere inotaura. Naizvozvo, panguva iyoyo vanotorwa uye kuedzwa kuti thyroid mahormone. Also vaiona kemikari pamwero ichiwedzerwa pakupindura kwokubatsira opioid fuma.

Thyroid-anotokonya kemikari pazasi dzose apo yakawanda thyroid mahormone muropa. The thyroid shwanu iri panguva unobereka zvakawandisa vavo uye ayo zvinorwadza kugadzirwa mahormone izvi Anoita pituitary kumisa kwetunhu uye secretion kuti thyroid-mutange kemikari. Uyewo huwandu muropa zvinoderedza panguva yenzara uye kushaya zvokudya zvinovaka muviri. It vaizongoguma kudukupiswa pamwe zvakakomba somatic zvirwere, uyewo vamwe vairwara nepfungwa, zvakadai seanorexia nervosa uye dambudziko kuvhiringidzika rebipolar. Uyezve, hatigoni haabatanidzi chirwere kukanganisa hypothalamus uye pituitary shwanu.

Thyroid-nekurukurirano kemikari anogadzirwa chete wevasungwa muvana uye vakwegura (kunze mangwanani chaizvo uduku uye vakwegura kwemakore 70), vakadzi nevarume. Kemikari anogadzirwa cyclically, kureba yakadaro duku kutenderera maawa anenge 2, mutinhimira uyu pedyo chaizvo kuti mutinhimira okuwana kemikari inonzi prolactin. Hazvina chokuita hypothalamic basa Zvisinei, anoratidza kuti pane zvimwe mashandiro runovabvumira waidzora mabasa vaviri mahormone izvi yakavanzika. Avaindipa kupfuura zvikuru usiku, ari manheru, iri somatic zvirwere, uyu nhamba kunoratidzirwa zvikuru kupfuura dzose.

Ndizvo kudaro kujairika kemikari ichi thyroid-mutange. Kazhinji rinokundwa pfungwa vanachiremba chete kana paine Kuvhiringidza ari thyroid shwanu. Asi iye kwazvo pamusoro angamuudza, kuti hakutadzisi kuti zvisinganzwisisiki chaizvo.
