The follicular gawo la kuzungulira kusamba

Follicular gawo - uyu ndi gawo loyamba la kayendedwe ka yamchiberekero, amene amakhala ndi kukula ndi kusasitsa wa follicle lapansi.

Follicular gawo kapena monga iwo ukutchedwa, esitirojeni, imayambira tsiku loyamba kusamba zimatha mpaka nthawi imene thumba losunga mazira ndiribe okhwima imodzi kapena dominants angapo follicle. Mapeto a imeneyi - ovulation.

Kutalika kwake kungakhale yosiyana. zambiri kuposa kuchedwa mwezi zimachitika chifukwa cha kusasitsa wozengereza follicle lapansi. Chinthu chachikulu zokhudza nthawi ya ndondomeko ino ndi nthawi zimatengera thupi kukwaniritsa mlingo pazipita timafunika.

Malinga ndi kusintha zinchito ndi morphological ambiri m'mimba kayendedwe ka mwezi akhoza kugawidwa mu magawo zotsatirazi:

1) Follicular gawo;

2) Ovulatory;

3) luteal;

4) kusamba.

Kuti gawo la kuzungulira, imbaenda ovulation amatchedwa follicular. Kawirikawiri, pamafunika yekha zoyambirira za kuzungulira, koma nthawi zina nthawi yaitali. Wapakati mkombero nthawi - masiku 28. kupatuka aliyense ku nambala iyi yokha chifukwa cha nthawi ya gawo follicular.

gawo Follicular amakhala ndi kuwonjezeka kukula mu kaphatikizidwe ndi kutulutsidwa estradiol ndi inhibin. Anthu ambiri awa ukuwonjezeka mahomoni osati kufalitsa zokhudza zonse, komanso madzimadzi follicular. Kwinakwake masiku 2 pamaso kusamba akuyamba chitukuko follicle ku mpumulo wake kapena mtundu primordial.

Monga pa nthawi ino n'kuwasanganiza akamwalira thupi chikasu, lomwe linakhazikitsidwa kumbuyo mu mkombero m'mbuyomu. The chifukwa cha ndondomekoyi - kuchepa lakuthwa mu ndende ya estradiol, progesterone, ndi inhibin (yotsirizira awiri mmene wamng'ono).

Pamasiku 4-5 a msinkhu umenewu dormancy kupitiriza kupita ndi kukhala yamchiberekero primordial follicles. Follicle-zolimbikitsa timadzi (FSH) akuyamba kupangira selo kuchulukana, amene ntchito kumawonjezera kwambiri. Izi zimachititsa kulimbitsa mapangidwe androgens estrogens ali apanga maselo interstitial.

Follicles anapanga mfundo zambiri alibe wosanjikiza umodzi maselo follicular azinga oocyte. Komanso, kuwundana ka madzimadzi follicular pali pakati pa maselo amenewa. Follicle-zolimbikitsa timadzi wayamba kupangira maonekedwe a nambala kuposa zolandilira kwa maselo LH ndi mwini. Ndipo kumawonjezera tilinazo awo luteinizing timadzi.

Gawo follicular amakhala ndi chakuti 6-7 tsiku adzizungulira, mmodzi wa follicles ndi akutulukira akuyamba yakulamulira. Basi iye ndipo adzakhala inakulitsidwa ndipo pambuyo ovulates pafupifupi 13-15 tsiku mkombero. Chifukwa cha follicle lalikulu amakhala ndi apamwamba mitotic ntchito maselo follicular, kudzikundikira apamwamba follicle-zolimbikitsa timadzi mu folllikulyarnoy madzi.

follicles Non-lalikulu ndi chiŵerengero mkulu wa androgens ndi estrogens, ndipo limati kuti maselo follicular utachepa ntchito aromatase. Chotero sanali lalikulu follicles amayambiranso (atresia). Androgens - chofunika kwambiri kulimbikitsa atresia.

Mochedwa ndipo pakati follicular gawo la kuzungulira kusamba amakhala ndi kuwonjezeka kwambiri kaphatikizidwe wa estradiol ndi inhibin B, imbaenda chopinga wa yopanga follicle-zolimbikitsa timadzi ndi pituitary England ndi mabasi kukula follicles latsopano. Kukula estradiol tidzapeze kuwonjezeka mu katulutsidwe wa luteinizing timadzi ndi kuwonjezeka mu tilinazo yamchiberekero kuti gonadotropins. Komanso, zili mkulu timafunika amachititsa kukula endometrial. kusintha amatchedwa "kuchuluka kwake".
