Implantation wa linagwira

Pambuyo umuna umalandira chiberekero, izo wakumana ndi dzira, iye udzaononga odula mapuloteni ndi ophatikizidwa mkati. Choncho umuna kumachitika, ndilo chiyambi cha njira ya chitukuko cha mwana wosabadwayo lapansi. Pambuyo pophatikizana ndi, makolo ndi akuchikazi chuma anapanga ukala dzira - mwana wosabadwa. Linagwira akapitirira siteji ena a chitukuko, yodziwika ndi kusintha kachulukidwe ndi Mkhalidwe. Koma kuti patsogolo chitukuko cha linagwira kunakhala kotheka, afunika sing'anga michere, umene pa miyezi isanu ndi inayi yotsatira kulandiridwa zakudya. Chotero sing'anga amakhala chiberekero.

Choncho, dzira mu Ukalawu akutsika mwachindunji mu chiberekero. Izi zimachitika chifukwa kukhalapo kwa villi tosaoneka mkati Ukalawu, omwe amalimbikitsa linagwira. Ngati Ukalawu ndi pathologies (adhesions, anaŵerama), ndi implantation wa linagwira ndi zovuta kwambiri, chifukwa njira m'chiberekero ndi mabvuto. Mu nkhani iyi, dzira akhoza anachedwa mu Ukalawu ndi Ufumuyo kumeneko. zodabwitsazi akutchedwa ectopic (Tubala) mimba ndipo amafuna alowererepo zachipatala.

Kawirikawiri, pamene dongosolo wabwinobwino wa machubu mazira ndi umuna dzira mu chiberekero imagwera mkati masiku anayi. Pa nthawi iyi, ndi mu siteji morula, koma ngati akulowa chiberekero - mu siteji blastocyst. Mbali imeneyi amakhala ndi chakuti dzira ndi wokonzeka kusintha latsopano. Blastomeres anayamba kupanga embryoblast - gawo la zomwe apitiriza kukhala Ndisanaumbidwe, ndi gawo lachiwiri la maselo - ndi trophoblast - a iwo ati apange phukusi chakudya cha mazira (gawo asonyeza wa trophoblast ya anakhala latuluka).

Apa wa implantation wa linagwira ndi anakulirakulirabe. Mchikakamizo cha kusintha m'thupi kwa iwo ndiponso kuwakonzekeretsa chiberekero. Pambuyo follicle akuphulikira, ndi corpus luteum aumbike, kumasuka kwakukulukulu progesterone, ndi wamng'ono - esitirojeni. Iwo progesterone chizindikiro chiberekero mucous nembanemba wa kufunika kukonzekera bedi lake. The kusintha choyamba mu chiberekero cha endometrial khalidwe - umatchedwa pa mimba decidua. Kodi pali kusiyana pakati pa endometrium latsopano? Mbali yaikulu ya endometrium wa - kudzikundikira pa mankhwala ake thicker bioactive kuti kuyamwitsa mwana wosabadwayo. Izi glycogen, mucopolysaccharides, lipids, salt ndi mme- zinthu, michere, immunoglobulins - onsewo ndi yofunika kuti implantation wa linagwira anapitiriza kutukula wa mwana wosabadwayo. Nthawi zina pamene pali zopindika mu endometrium ndi ntchito zake, mkazi kwa nthawi yaitali simungathe kutenga mimba, ndipo nthawizina iwo kukhala osabereka.

Mu yachibadwa endometrium linagwira implantation kumatenga masiku awiri. Panthawi imeneyi, mu malo kuphatikana (nidation) dilates Mitsempha, unakhuthala endometrium. kusintha awa akusonyeza kuti chiberekero ndi wokonzeka kulandira blastocyst. Pamene adalowetsedwa ndi linagwira mu makulidwe a endometrium ndi ngati kuphimba chiberekero villi. Nthawi zina kuphatikana izi zikhoza kukhala limodzi ndi magazi zazing'ono, zomwe angalakwitse chifukwa chiyambi cha mwezi mochedwa. Komabe, kuchuluka kwa magazi ndi yaing'ono kwambiri - madontho ochepa kapena malo ochepa, ndiye "magazi" ndi ndinayima. The implantation wa linagwira ntchito, ndi zizindikiro zimene sizili perceptibility mkazi, njira zikungopangitsa lokha anamva, monga izo zimachitika pakati pa kuzungulira, pambuyo ovulation, koma kutali isanayambike menses. Ngati akazi aziziyang'anira m'zinthu awo ndi kudziwa nthawi ya ovulation, m'pamenenso iwo ali kuyembekezera mimba. Ochepa okha akazi implantation wa linagwira ntchito, ndi kumverera mwa njira iliyonse kuonekera pa implantation. Nthawi zina kumva kulasalasa, nseru, kumverera kwa kulemera. Komabe, iwo amayamba ndi implantation palokha, ndipo limasintha akaleka mu thupi.
