Isigaba luteal

Isigaba Luteal - na ixesha ukuba sexesheni, apho kukho iinkqubo morphological kwaye zisebenza uthatha indawo isizalo apho kwenzeka komsipha follicular.

Isigaba Luteal: ekuqaleni

Xa ovulation, granulosa inwebu (okanye ubizwa ngokuba follicle udonga graafova) iqhuma. Ngenxa yale msantsa kwenzeka ukuvuza follicular cerebrospinal kunye Cumulus oophorus equlethe iqanda, kuloo ndawo ibinomthwebeba peritoneal. Ngeli xesha kunciphisa follicle. Xa ingqibelelo kantu epithelium vascularized kunye theca, ukuwa isidima inwebu beempahla ezincinane. Kokuba babe balindeleke ukuba kukho ukuhla kuxinzelelo intrafollicular ophela ukuya ingxa- le follicle.

Kweli nqanaba, coagulation igazi, emva kwethuba elifutshane, le ihlwili legazi lithuthwa. Kwiintsalela granulosa inwebu (follicular iiseli epithelial) yokudibanisa iziqalelo ze theca lwangaphakathi aqale ukwanda kunye hypertrophy. Emva koko kuntshula ibe follicle epitelievidnyh ezikroziswayo ihlwili igazi kunye nokuphela kwegqabi sele gqobhoza uqalisa ukwakha iiseli ezinkulu. Bandile ubukhulu, izidumbu zabo zibe ajikelezayo ngakumbi yaye inani labo uyakhula. Xa kukho icytoplasm, elingumthombo accumulated granules-orenji-tyheli eqinileyo (lutein) kunye zamathontsana namanqatha.

Kuxhomekeka apho kwenzeka iiseli, ukwahlula izinto efunyanwe granulosa inwebu (iiseli granulosa lutein) kunye theca (tekov iiseli luteal).

Ngoko ke, indibano iseli kwaye nesabelo salo ephakathi endaweni follicle indlebe igcinwe amasalela ihlwili legazi, leyo yantshula umqadi kwizicwili. imfundo enjalo uye wabizwa sanguinolentum (corpus haemorrhagicum).

Substance bulubhelu - lutein - umbala ukubunjwa esele iqalisa ukwanda ubungakanani, umbala-orenji-yellow. Kanye apha igama "umzimba etyheli 'okanye corpus luteum yakhe.

Ecaleni imiphetho, phakathi izihloko iiseli lutein etyheli, iqala ukuhluma besusa imithambo yegazi ezingcakacileyo kunye zomzimba nokuqina. Ngenxa yoku, kwaye ajike ilungu elincinane epithelial iyafana kakhulu kubume ibe ingaba yonyango. Isigaba Luteal luphawulwa yi kukuba lo gama iiseli leyo NdinguMenzi maqhuqhuva, nomqadi igcwele phantse onke luteum corpus. Ngoko walahlekelwa zonke iintsalela ekuqaleni ibekwe ihlwili umzobo.

ibinzana Luteal: ekupheleni

Ekuhambeni kwexesha, lo luteum corpus ikhula ubukhulu. Kulo mzekelo, endaweni follicle iqala kukuma phandle ngokucacileyo phezu kwamanzi jikelele isizalo. Ukuba ekukhulelweni kuye akukenzeki, kwaye siphane iqanda, leyo wakhululwa naxa ovulation ophelileyo, luteum corpus ngeveki iza ubukhulu ukuya cherry encinane. Emva koko eyeka uphuhliso kunye baqale utshintsho sisiba mandundu, nto leyo iphelela nokushiywa ngokupheleleyo. Lo mzimba, nto leyo ibunjiwe ufakwa ukubuyisela uphuhliso zonke iintsuku ezingama-28, ubizwa ngokuba "sexesheni umzimba omthubi."

Isigaba Luteal iphela kunye iiseli zomzimba ngokuhamba kwexesha, sokudiliza endaweni yayo uya kwizicwili. Emva koko, endaweni luteum corpus kubonakala kukuqulungana shiny kwaye ezimhlophe, nto leyo iquka ilaphu ngokwanelisayo ashinyeneyo. Le umzimba iye ebizwa okanye ezinezikhondo ezimhlophe. Ukuba usafuna kumitha, lo luteum corpus akuthethi nje bahlale isizalo, lisaqhubeka ukukhula ubungakanani kunye umsebenzi ukuya kumbindi yokukhulelwa.

Ngenxa umsebenzi yonyango, i luteum corpus sisiphango ukuba ezinye zoboya amanyathelo. A ecula, akukho kuqhubeka ukwahlula igazi.

Ukushwankathela: kwisigaba luteal ukuba sexesheni - isigaba kwenzeka emva ovulation. Endaweni follicle indlebe ubonakala umzimba etyheli, xa kwamaqanda aqhamileyo, lo luteum corpus iyaqhubeka ukusebenza nesiqingatha ukukhulelwa. Ukuba zange yenzeke kwezichumiso, ngexesha elililo sexesheni iqala.
