Isigaba se-Luteal

Isigaba salo luteal yisikhathi somjikelezo wokuya esikhathini lapho izinqubo zomsebenzi nezokuziphatha zivela khona esibelethweni lapho kuqhuma khona ukuphoqa.

Isigaba se-Luteal : qala

Lapho ukuvuthwa kwenzeka, i- membrane ye-granular (noma ebizwa nangokuthi udonga lwendoda ye-graafial) iphukile. Ngenxa yalokhu kuqhuma, umthamo we-follicular ugeleza futhi i-tubercle ethwele amaqanda, equkethe iqanda, ingena emgodini wesisu. Ngalesi sikhathi, i-follicle iyawa. Lapho ubuqotho be-epithelium ye-vascularized kanye neyamanje buphazamiseka, ubuqotho bezitsha ezincane bubhidliza egumbini. Baqala ukuphulukisa endaweni ye-follicle evuthayo ngenxa yokuncipha kwengcindezi ye-intraflexic.

Kule ndawo igazi lihlanganisa, emva kwesikhathi esifushane leli phuzu legazi liguqulwa. Izinsalela zekhanda le-granulosa ( amangqamuzana e- follicular epithelial) ahlangene nezakhi zangaphakathi zamanje, ziqala ukuxhunywa komzimba futhi zanda. Ngemuva kwalokho, zihluma zibe yi-clot yegazi futhi ungqimba lwamangqamuzana amakhulu e-epithelial aqala ukwakha emaphethelweni e-follicle esele iqhume. Banda ngesayizi, imizimba yabo iba yindilinga futhi inombolo yabo ikhula. Esikhathini se-cytoplasm, okwamanje, iziqu ze-orange-yellow yellow (lutein) kanye namaconsi amafutha atholakale.

Kuye lapho amaseli avela khona, izakhi ezivela egumbini le-granulosa (amangqamuzana e-luteal granulosa) nakwamaseli (amangqamuzana angama-luteinic) ahlukile.

Ngakho-ke, kuhlanganiswa isunithi yamaselula futhi engxenyeni yayo ephakathi, ingxenye ephumayo ye-clot yegazi ihlala endaweni ye-follicle eqhumekile, ehlume nesikhwama sezingxube ezixhunyiwe. Lokhu kwakhiwa kwakubizwa ngokuthi i-sanguinolentum (corpus haemorrhagicum).

Ingqikithi yombala ophuzi - i-lutein - imibala ukwakheka, okuvele sekuqala ukwandisa usayizi, kumbala ophuzi obomvu. Kwavela lapha ukuthi igama elithi "umzimba ophuzi" noma i-corpus luteum livela.

Emaphethelweni, phakathi kokuqoqwa kwamaseli e-lutein aphuzi, ukuhluma kwezinqwaba zezitsha kanye nezicubu ezixhumeneyo ziqala. Ngenxa yalokhu, kutholakala isitho esincane se-epithelial, efana kakhulu nesakhiwo se-endocrine gland. Isigaba salo luteal sibonakala ukuthi phakathi kwamaseli ayo, akha amaqhudelwano kanye nemigodi, agcwalise cishe wonke umzimba ophuzi. Ngakho unqabe zonke izinsalela ze-clot yangempela ye-croc.

Inkulumo yokukhuluma: ukuphela

Ngokuhamba kwesikhathi, umzimba ophuzi ukhula ngobukhulu. Kulesi simo, esikhundleni se-follicle, iqala ukubonakala ngokucacile ngaphezu kwendawo ejwayelekile ye-ovary. Uma kwakungekho ukukhulelwa kanye ne-inoculation ye-ovum, eyakhishwa ngisho nangesikhathi sokuvuthwa kwangaphambilini, ngesonto kamuva umzimba ophuzi ufinyelela usayizi kuze kufike cherry encane. Ngemuva kwalokhu, ukuthuthukiswa kwayo kumiswa futhi izinguquko ezishintshayo ziqala, okuphela ngokucindezela okuphelele. Lo mzimba, owakhiwa futhi ohlotshaniswa nokuguqulwa kwentuthuko njalo izinsuku ezingu-28, ubizwa ngokuthi "umzimba ophuzi wokuya esikhathini."

Isigaba soguquko siphelela ekugcineni ukuthi amangqamuzana omzimba loyo ekugcineni ahlukaniswe futhi izicubu ezihlangene zihlangene endaweni yawo . Ngemva kwalokhu, esikhundleni somzimba ophuzi kubonakala sengathi i-hem ekhanyayo futhi emhlophe, enesisindo esinomsoco. Lo mzimba wabizwa ngokuthi umhlophe noma u-fibrous. Uma ngabe kunjalo ukukhulelwa, umzimba ophuzi awugcini nje ovary, uqhubeka ukwandisa usayizi nemisebenzi kuze kufike phakathi kokukhulelwa.

Ngenxa yomsebenzi we-endocrine, umzimba ophuzi unomthelela omubi kwamanye ama-follicles. Ngenye i-solo, ayiqhubeki ukuhlukanisa igazi.

Ake sicacise: isigaba sokuqeda umjikelezo wesimiso yisigaba esilandelayo emva kokuvuthwa. Endaweni ye-follicle ephukile ivela emzimbeni ophuzi, Uma iqanda lifakiwe, umzimba ophuzi uyaqhubeka ukusebenza ngisho nengxenye yesikhathi sokubeletha. Uma ukukhulelwa kweqanda kungenzeki, isikhathi sokuya esikhathini siqala ngesikhathi esimisiwe.
