The nzvimbo uye maumbirwo ovary

musikana ose uye mukadzi chete kuziva chii mukati muviri wake. Kunyanya kubva ane chete masimba emashiripiti - kureva kukwanisa bereka kuberekwa kwevanhu.

We anoratidza pepa rino kuti funga sechivako ovary, dumbu, uye avo mabasa. Nesuwo kutaura nezvevamwe zvinetso zvinogona kutarisana akanaka pabonde. Ngatitange nepfungwa yokuti ovaries vari aiwanzopiwa wokushanda mumasero dzepabonde chinangwa. Ovaries mabasa makuru maviri Mabasa: kuti kwemakemikari anobudiswa uye rokubereka. Isu uchapisika nezvazvo ichi gare gare. We hunoratidza kutanga nemamiriro gonads mashoko.

The nemamiriro ovaries

Sezvatakamboreva, kuti ovaries - iri aiwanzopiwa wokushanda nhengo, iyo ndiyo mumasero dzepabonde munhukadzi muviri. Zvaiva imomo kuti paumbwe uye kuibvisa pamusoro oocytes. Usati kutarira chimiro ovary, kuti kuona sei papi hama zvitaviro nevamwe vakadzi. The ovaries dziri pamusoro kana divi dumbu. Mumwe nomumwe wavo maererano pelvic sidewall.

Vane rakachenuruka rinokwanisa kucheneruka ruvara, gogonera Nechepamusoro, ovaries pachavo denderedzwa uye zvishoma flattened chimiro. ovary Chimiro - iri chaizvoizvo mubvunzo wakaoma chaizvo. Govera pamusoro yavo:

• medial;
• lateral.

Territory:

• mesenteric;
• free.

Miromo miviri:

• Pipe;
• mai.

Zvino zvishoma pamusoro nzira. In vakadzi vakura ovaries vanogona kusvika zvinotevera kukura, Chokwadi, tinofanira kufungawo zera uye munhu unhu:

Mumwe ovary ane unhani ari chimiro tunica albuginea, ventral chikamu vari zvakabatanidzwa chete kuburikidza Fusion peritoneum uye mesenteric mucheto. Pasi tunica anewo cortical layer iri akasimba zvikuru kupfuura pakutanga, pane glandular tishu. Pakati ndiwo anonzi medulla, iyo inozivikanwa nokuvapo nenhumbi zhinji uye ayo nokusazvibata kusachinja-chinja achida sezvo connective tishu.

We kuonawo kuti cortex rine follicles, izvo rakakamurwa mifananidzo:

• chikuru;
• vesicular.

Chokutanga pane yatakanyora pasi - kwete follicles vachikura, yokupedzisira ratova zvakazara akakura ane follicular mvura. Kuti akaumba chikuru kurara masero - zai. The akura follicle uye zai zvinobatanidzwa nedanho ovulation. The dzinokaroparuka wokutanga, zai Uchibviswa nomukombiyuta fimbria kupinda uterine mhango kuburikidza fallopian chubhu. Dzimwe nguva zvinoitika kuti follicle anotanga wokuparadza, uye kwete ndapedza kuibvisa yavo.

The nemamiriro dumbu

Funga zvinotevera mubvunzo - maumbirwo of dumbu uye ovaries. mitumbi maviri aya chokuita nomumwe. Zviri Joint basa dzinovabvumira bereka uye mberi rudzi rwevanhu. The dumbu ane peya chimiro, pakurema kwayo dzinowanzoona - 40 kusvika 60 magiramu. In ayo mamiriro emit:

• muviri;
• pamutsipa;
• Isthmus.

Zvakakosha kuziva ndechokuti dumbu chinhu mukaha nhengo iri mukati ane akasununguka mhango. masvingo aro vari bata, ndokusaka Kamuri iri sokunge munhu slots.

Patsanura akaturikidzana masvingo:

• endometrium kana mucous Kamudzira, - imwe rukoko yomukati;
• myometrial kana tsandanyama, - munhu pakati rukoko pakati uterine rusvingo;
• serosa uye peritoneum ndiwo okupedzisira, rokunze rukoko pamusoro dumbu.

Kuurungana kaviri shanduko chero vakadzi basa. Endometrium ukobvu inogona kubva kune zvitatu millimeters (izvi zvose kunobva kutenderera danho). myometrium hapana shanduko kuti bermennosti uye kusununguka, pakukora neeSultan kubva matatu kusvika gumi millimeters. Wokupedzisira rukoko anofukidza zvose munhukadzi zvomukati.

Tiri kupa muchidimbu pfungwa huru uye mashandiro chinangwa muviri ichi:

• kudzivirira chirwere;
• nokuzvidzora kuchenesa;
• kutakurwa spermatozoa;
• muchibereko;
• pakusikwa mamiriro ezvinhu embryo;
• makatodzinga azvarwa (pakusununguka);
• vachisimbisa pelvic pauriri.

ovarian basa

Takurukura izvi nhengo dzakavandika, kuti dumbu uye ovaries, avo marongerwo. Uye kushanda ovaries - yedu mubvunzo unotevera. Tiri panotangira nyaya kutaurwa kuti ovaries vane mbiri zvikuru mabasa:

• rokubereka;
• kwemakemikari anobudiswa.

Mashandiro rokutanga - ndiye paumbwe bonde masero. Tinopa kumboongorora nedanho oogenesis. Zvakasiyana nedanho spermatogenesis, zvinhanho zvitatu akasiyanisa ose:

• kubereka;
• kukura;
• kuibvisa.

Panguva yokutanga chokutambudzika kubereka kunoitika oogonia, izvo kazhinji kacho zvinoitika panguva fetus. It chinomisa muitiro apo sero achipinda meiosis. Panguva iyi pakukura anomiswa pamberi pakuyaruka. Kukura Danho unobuda panguva akura ovary iyo inoshanda. Wokupedzisira danho inotanga kuti murayiro wechipiri kuumbwa oocytes, uye inoguma muitiro goho kubudikidza ovulation.

Musiyano mukuru kubva spermatogenesis - ndiko kushaya inotungamirwa pechikuva.

We ataurwa mumwe ovarian nerevane - kwemakemikari anobudiswa. Granulosa vane mabasa vari yaidzorwa kune mukuru kumwero lutropin, berekai mahormone:

• estradiol, testosterone aizotangira aumba kubva;
• estrone, estriol zvinobatsira paumbwe placenta uye chiropa;
• progesterone, iyo kunotodiwa panguva ovulation.

Kukura ovaries

Tava akaongororwa sechivako ovary vakadzi vava kupa chaizvo zvishoma kutaura kukura kwake.

Zvinofanira kucherechedzwa kuti paumbwe muviri uyu kunotanga munguva fetus. Nechekare mumwedzi wechishanu vasikana vane dzakasimukira zvakazara gonads, vari follicles. Pashure paizvozvo, vachaita atrophy. Zvizere ndizvo zvinoumba ovaries vari vasikana vaduku nemakore maviri.

pamuviri

Tava akataura nyaya nemamiriro ovaries, sepombi, zai. Asi chii chinoitika mumuviri mumwe mukadzi panguva yepamuviri? Ovarian basa kuramba basa, kureva kugadzirwa zvakakodzera mahormone. Ndirwowo paucheche mazai achikura. Panguva pakusangana corpus luteum mbeu achiumbwa mumwe ovaries maviri. Zvakafanira kuti kunowedzera kugadzirwa progesterone. Yellow muviri kunobatsira kuti zvakazara kuumba placenta, vhiki nemiviri rwunotanga wasvava, sezvo basa rayo guru iri aurayiwe.

Unofanirawo kuziva kuti munguva pamuviri mukadzi ovaries kupinda "kuhwanda" kuti hazvina kuitika inotevera ovulation.

kuneta

Tatoona dzomunyika urongwa ovary, asi havana kutaura nezvezvinoitika kuparadzwa kwavo. Chii? chirwere ichi kunotaurwa zvishoma vaSia (Kuparadzwa ovarian urwere). Uye ichi unosanganisira zvakawanda rose nezviratidzo:

• amenorrhea;
• kuvhiringidzika vascular ino;
• kushaya mbereko kuti vabudirire mukadzi makore 40 okuberekwa.

chirwere ichi kunogona kuita kuti vanachiremba pamusoro ezvinhu kuti mukadzi akanga asina kare nematambudziko vaine kumwedzi uye pamuviri ushande. Pasinei yakatarwa iyi zviratidzo, chirwere chacho chose rinorapika.

Multifollikulyarnost

Multifollikulyarnoe ovarian Chimiro iri kusvika indistinguishable kubva mamiriro utano, musiyano chete ndechokuti muna ovaries panguva imwe chete, pane sere kana kupfuura follicles. Norm - kubva 4 7, zvizere kuibvisa pavo richisvika mumwe chete, kashoma maviri. Multifollikulyarnost anogona kuonekwa ne Ultrasound (US), mufananidzo uri sezvinotevera: ari ovaries zvikuru follicles mumatanho manomwe ichiibvira.

Zvakakosha kuziva kuti kushandisa Ultrasound zvakaoma kuziva chaiyo zvokuongorora nokuti multifollikulyarnost anogona kunyatsotevera akafanana cystic chirwere. Kana ngozi akaona zano waakaudzwa pedyo gayinakorojisiti uye kuongorora kuti kuona hormone siyana.

kubviswa

Mune zvimwe zviitiko, ovaries vanobviswa. Ngatikurukurei muchidimbu nzira kana vari pasi kubviswa:

• kemikari-muyanzvi zamu anomera;
• chikofu;
• kenza;
• zvomoto pelvic nhengo.

Ovaries, STRUCTURAL zvinhu takawongorora, kazhinji pasi kubviswa pamwe fallopian sepombi. Pashure nokubviswa ovaries maviri mukana wokusvika pamuviri, unogona hauchafambi kutaura. Chokutanga, muitiro rinomira ovulation uye kumwedzi iri wakagumiswa. Uyezve, mumuviri akaona kushaya estrogen, saka kuti endometrium atrophies.

Tava akaongororwa sechivako ovary akanyorwa vamwe chirwere. Yeuka kuti utano vakadzi kuchikosha chaizvo kutarisira, nekuti zvinokanganisawo kukwanisa kuva nevana.
