Gawo luteal

Luteal gawo - ndi nthawi ya msambo, imene pali morphological ndi zinchito njira ikuchitikira n'kuwasanganiza kumene follicular chotupa zinachitika.

Luteal gawo: chiyambi

Pamene ovulation, granulosa Kakhungu (kapena amatchedwa follicle khoma graafova) utaphulika. Chifukwa cha kusiyana izi zimachitika kutayikira la follicular madzimadzi ndi cumulus oophorus muli dzira, kuti patsekeke peritoneal. Panthawi imeneyi amachepetsa follicle. Pamene umphumphu linaphwanya vascularized epithelium ndi theca, kugwa nembanemba umphumphu wa ziwiya yaing'ono. Iwo chifukwa kuchepa kuthamanga intrafollicular magazi kwa akuphulikira wa follicle lapansi.

Pa nthawi imeneyi, magazi coagulation, patapita kanthawi kochepa, izi aumirira magazi losandulizika. Zatsalira granulosa Kakhungu (follicular zaminyewa maselo) kaphatikizidwe ndi mfundo za theca mkati anayamba zikupitiriza ndi hypertrophy. Pambuyo kumera mu magazi aumirira ndi m'mbali kale utaphulika follicle epitelievidnyh wosanjikiza amayamba maselo zikuluzikulu. Iwo kuwonjezera kukula, matupi awo kukhala anamaliza ndipo chiwerengero chawo ikukula. Mu cytoplasm ndi azungu anasonkhanitsa granules lalanje-chikasu olimba (lutein) ndi m'malovu mafuta.

Malingana ndi kumene maselo zinachitika, kusiyanitsa zinthu amachokera ku granulosa Kakhungu (maselo granulosa lutein) ndi theca (tekov maselo luteal).

Choncho, selo msonkhano ndi gawo wofunika m'malo mwa follicle utaphulika kokhazikika zotsalira za magazi aumirira, amene utakula mtengo connective minofu. maphunziro umatchedwa sanguinolentum (corpus haemorrhagicum).

Mankhwala chikasu - lutein - mtundu mapangidwe kale wayamba kuonjezera kukula, mtundu lalanje-chikasu. Monga choncho dzina lake "chikasu thupi 'kapena corpus luteum.

Pamodzi m'mbali, mwa matsango a maselo chikasu lutein, akuyamba kumera tufts ziwiya woonda magazi ndi minofu connective. Chifukwa cha ichi, ndi likukhalira pang'ono zaminyewa limba ndi ofanana kwambiri dongosolo ndi endocrine England. gawo Luteal amakhala ndi chakuti pamene ndi maselo amene apanga tinatake tozungulira, ndi mtengo wodzala pafupifupi corpus luteum. Choncho anataya zotsala zonse poyamba inali aumirira sewero.

Luteal akuti: mapeto

Pa nthawi ya corpus luteum umakhala kukula. Pankhaniyi, m'malo follicle ndi zimayamba kuoneka bwino padziko wonse wa n'kuwasanganiza lapansi. Ngati umuna sizinachitikebe, ndi kupatsana dzira limene linatuluka ngakhale pamene ovulation yapita, corpus luteum mu sabata amatuluka mu kukula kwa chitumbuwa yaing'ono. Pambuyo mabasi chitukuko ndi kuyamba kusintha osachiritsika, zimene mu mgwirizano wathunthu. thupi ili, zomwe likakhazikitsidwa komanso ali nako kusintha chitukuko iliyonse masiku 28, amatchedwa "kusamba chikasu thupi."

Luteal gawo umatha ndi maselo a thupi pa nthawi, kuphwanya ndi malo ake ati minofu connective. Pambuyo pake, mmalo mwa corpus luteum limapezeka chonyezimira ndi yochitidwa chilonda, chomwe ndi nsalu mwachilungamo wandiweyani. thupi ili imene imatchedwa kapena yochitidwa fibrous. Ngati muli pakati pa corpus luteum samangofikira kukhalabe n'kuwasanganiza, iwo anapitiriza kukula kukula ndi ntchito pakati pa mimba.

Chifukwa ntchito endocrine, ndi corpus luteum zedi wosonyeza kuti follicles kuchita zinthu zina. Nightingale A, zilibe kupitiriza kupatukana magazi.

Kuti adzimvera: gawo luteal a kuzungulira kusamba - gawo zikadzatha ovulation. M'malo mwa follicle utaphulika limapezeka thupi chikasu, pamene dzira ndi ukala, ndi corpus luteum akupitiriza liziyenda ngakhale hafu ya mimba. Ngati izo sizinachitike umuna, mu nthawi yake kusamba akuyamba.
