Ke follicular pae o ka menstrual pōʻaiapuni

Follicular pae - keia mea i ka mua pae o ka ovarian kalapona, a ua wehewehe aku ma ka ulu a me ka maturation o ka follicle.

Follicular pae 'ole e like me ka mea i kapaia, estrogen, e hoʻomaka me ka lā mua o ka menstruation a mau a hiki i ka manawa i ka wa a na ovaries i oleʻoihana kaua i kekahi a me kekahi mau dominants follicle. I ka pau ana o keia pae - ovulation.

Kona lōʻihi like 'ole i ia heʻokoʻa. More pinepine ma mua o malama ka holo koke ana no ka mea, o ka mea kali maturation o ka follicle. I ka papa kuhikuhiE ololi e loli ai i ka lōʻihi like 'ole o kēia kaʻina hana o ka manawa e lawe ai i ke kino, e kū ai i ka i kā mākou kiʻekiʻe o ka estrogen.

E like me ka loiloi, a morphological loli ma na ovaries malama kalapona hiki ke maheleia i na kēia kūlana:

1) Follicular pae;

2) Ovulatory;

3) luteal;

4) Menstrual.

I ka pae ana o ka pōʻaiapuni, i hiki aku ai i ovulation ua kapaia ka follicular. IeAUPIIe, IAa IO, ka mea lawe wale i ka hapa mua o ka pōʻaiapuni, akā, e hiki i kekahi manawa lawe hou. Ka awelika kalapona manawa - 28 lā. Kekahi haiahū kūmau mai keia helu wale, kena ae la ia e ka lōʻihi like 'ole o ka follicular pae.

Follicular pae ua wehewehe aku ma ka ulu mahuahua ma ka hoʻololi kemikala a me ka hoʻokuʻu o estradiol a me ka inhibin. I ka lehulehu o kēia mau hormones, piʻi pū,ʻaʻole wale nō i loko o ka systemic holo, akā, i loko o ka follicular loli. Somewhere 2 lā ma mua menstruation hoʻomaka follicle ulu mai kona maha ai 'ole primordial palapala.

Anna i keia manawa ma ka ovary make yellow kino, i ka hana hou i loko o ka mua pōʻaiapuni. I ka hopena o kēia kaʻina - kaʻoi emi ana i loko o ka lehulehu o ka estradiol, progesterone, a me inhibin (ka hope elua he uuku loa).

Iloko o ka 4-5 lā o kēia pae o ka dormancy hoʻomau, e hele mai, a hoʻomōhala ovarian primordial follicles. Follicle-noho haumāna kahi hōmona (FSH) hoʻomaka e induce ke kelepona hele ka hoʻonuiʻana, a hana maoli he nui. Kēia hualoaʻa ma ka hooikaika ana i ke kahua o androgens estrogens i synthesized interstitial keena.

Follicles i hanaʻia ma kēia wahi ana, aole i ka hookahi ahu iho la ka follicular keena a puni i ka oocyte. Eia hou kekahi, he uuku huhui waina a lākou o follicular loli malaila ma waena o kēia mau keena. Follicle-noho haumāna kahi hōmona hoʻomaka e induce i ke ano o ka hiki nui helu o receptors no ka LH a me ka iho receptors. A me ka mea maoli he lākou pā lonoaʻili i ka luteinizing hōmona.

Ke follicular pae Ua wehewehe aku ma ka mea i ka 6-7 lā kalapona, kekahi o ka ka pukaʻana follicles hoʻomaka e Kīwala'ō. Pono oia, a e e hou ke kino, a ma hope o ovulates e pili ana i ka 13-15 lā kalapona. No ka mea Hoʻohaku follicle ua wehewehe aku ma ka mea kiʻekiʻe loa mitotic ha awina o follicular keena, ka mea kiʻekiʻe loa hoʻomāhuahua o follicle-noho haumāna kahi hōmona ma folllikulyarnoy wai.

Ole-Hoʻohaku follicles i ke kiʻekiʻe lākiō o androgens a me estrogens, a me ka mea i olelo ia i loko o ka follicular aeee ua hoʻemi aromatase haʻawina. Ia 'ole-Hoʻohaku follicles regress (atresia). Androgens - he ki ololi i inducing atresia.

Late a waenakonu follicular pae o ka menstrual kalapona ua wehewehe aku e kekahi i oi aku ulu i loko o ka hoʻololi kemikala o estradiol a me ka inhibin B, i hele aku ai i inhibition o ka? Iecaianoaaiiie o follicle-noho haumāna kahi hōmona ma ka pituitary gland a me ka mahana i ka ulu ana o hou follicles. Ulu o ka estradiol i hiki aku ai i ka hua i loko o ka secretion o luteinizing hōmona a me ka uku paneʻe ma ovarian pā lonoaʻili i ka gonadotropins. Eia hou, i ka maʻiʻo kiʻekiʻe o ka estrogen ke kumu no ka ulu ana endometrial. Oia loli i kapaia "ka hoʻonuiʻana pae".
