Meet musoro yedu huru - Pituitary Brain

Chero kunzwisisa maitiro anogona chete kuvapo nemhaka nhungamiro yakavimbika. Ichokwadi, rikaratidzwa nhoroondo uye nguva. Muviri - ndiko kuva dzakaoma kunzwisisa hurongwa kuti ishande zvakanaka pasi utungamiriri kwemakemikari anobudiswa uye huta nehurongwa. A maneja mukuru rose nyaya ndiyo uropi pituitary shwanu. Ndianiko shasha uyu?

The pituitary shwanu uropi riri duku zvikuru uye imperceptible. Growth rapera, kukura zvakafanana zviduku nati matanda, uye uremu vasingagoni kutaipa - magiramu 0,65 chete zvichidzika. Externally inoitwa zvikamu zviviri. Front yakafukidzwa glandular zvinyama undovakira - huta. Nokuda Unyengeri hwakadini ichi kunogona anotaurwa nemazita maviri. Kana isu nezvazvo mugove wokutanga, kunonzi Anterior pituitary. Kana totaura huta chezvinonhuwira shamwari yedu, kuti zita rake riri dzimwe nguva akaita neurohypophysis ichi.

Geniuses hadziwanzowaniki chaizvo, saka vanofanira kuchengetedzwa. The pituitary shwanu uropi hakuna anosara. Kuti hapana chakaitika kwaari, akagara anodzivirirwa zvakanaka nzvimbo - mune nehope kuzvimbirwa. Zvinonzi rakamiswa pedo mujinga uropi iri Chigaro, akadana munhu kuti Turkish.

Pashure penguva pfupi kuziva unhu imwe shasha anozodzidza shasha ake mano. Ivo kuchinja mabhora siyana upenyu hwevanhu. Kubereka mwana, kwokuyamwisa mwana, nokuti mwana akure mukuru; kuti arege kufa nenyota munguva dzenhamo uye urwere, vane utano uremu uye BP, kuti afare uye vane simba zvakakwana - unoda pituitary shwanu. Kutyora mashandiro anoita shasha ichi zvinoomesa zvikuru upenyu.

Chii chinobatanidzwa simbi ichi chinoshamisa? It inobereka mijenya akasiyana vanoshingaira zvinhu, makatumidzwa vanhuwo neshoko - mahormone. Ava chete mahormone anokosha chaizvo. Zvose pamusoro pezvakaitwa mumuviri yedu hazvisi zvinogoneka pasina mahormone. Saka kuti kukura, unoda somatotropin kemikari (vanhu inozivikanwa se kukura kemikari). Conception uye fetus hazvibviri pasina FSH uye luteinizing kemikari. Pakuzvarwa, akatanga kurwa kunokosha chaizvo oxytocin uye prolactin haasi asina mai mwana anodiwa saka mukaka.

The pituitary shwanu uropi hakusi zvakakanganisa. mabasa ayo anogona kudzimika. Pituitary chirwere akafanana kana kurwara Manager uye kwete kutsiviwa. Mumamiriro ezvinhu akadaro, vanowanzotanga zvimwe zvinetso kugadzira muitiro, sokunonoka uye kunyange achidzima kakawanda. Zvakafanana kunoitika apo pituitary shwanu rinomira pakuburitsa chero mahormone kana avo anopinda muviri chaizvo diki (kunaka) kana kwazvo (zvakawandisa).

Makemikari sei pituitary-zvaanoda kwemakemikari anobudiswa nhengo dzakadai adrenal omumuviri, ovaries, rwatata uye thyroid. Mumwe nomumwe wavo inotungamirirwa dhipatimendi yake uye anoita mabasa pamberi wake pituitary shwanu. Naizvozvo, kana kukundikana kunotangira pituitary shwanu, rose kwemakemikari anobudiswa hurongwa zvinopera, zvichiguma nezvinetso zvakakomba yose muviri.

The pituitary anotanga kukundikana nokuda namamota, izvo muka kubva wakakurumidza kukura kweprostate. Rinotanga muitiro majini mutation, uyewo zvimwewo zvinhu - murombo zvezvakatipoteredza ezvinhu, mwaranzi, zvokuimba kwazvinoita uropi. It anowedzera uwandu glandular zvinyama zviri pituitary kazhinji gogonera: vamwe masero kuva kwazvo tichiregeredza nevamwe. Somugumisiro masero iwayo zvizhinji, ichibudisa nekumwisa hormone, uye vaya vasina kukwana, kukonzera kushaya zvimwe mahormone. Hormone mwero anonetseka. The mugumisiro - the siyana zvikuru: kubva zviduku kutyorwa kumwedzi kupedzisa kukundikana yose kwemakemikari anobudiswa hurongwa. Zvapedzisira Mhosva munyaya zvakadzama uye tsanangura anozivikanwa endocrinologists zvakadai, sezvo Nikolay Itsenko uye Harvey Cushing. chirwere ichi zvinowanzooneka anotaurwa nemazita avo rokutanga.

Zvinosuruvarisa kuti kudzorera zvakazara huchaita pituitary mashandiro zvevakomana hazvibviri, sezvo isina ainyatsonzwisisa zvikonzero kutyorwa izvi. vanachiremba All kuita kuti kudzidzisa murwere kuramba kwemakemikari omuviri nepakati pamwe kemikari Sevamiririri kuti vanotorwa upenyu.
