Izici ezithandwa ngu-Anatomical nemisebenzi yama-ovari
Njengoba kukhonjisiwe ngenhla, ngesakhiwo se-ovary secretions of cortical and brain substance. Eyokuqala iqukethe izintambo eziyisisekelo, eziyisibili, eziphakeme, kanye nemizimba emhlophe nephuzi.
Kodwa-ke, ngokuthuthukiswa kwe-pathology, izinguquko zenzeka. Ngakho, phambi kwesifo, isakhiwo sezitho sishintsha, bese sikhuluma ngama-ovaries we-polycystic ( multifollicular ). Kulesi simo, kunyuke inani lemali yama-ovari.
Esikhathini sokwakhiwa kwe-medulla ye-ovary yowesifazane, eyakhiwa izicubu ezixhunyiwe, imithwalo yegazi, ama-apparatus wezinzwa, nezintambo ze-epithelial azivamiseki. Ngokuvamile kubangelwa ukuthuthukiswa kwezifo ezifana ne-cyst ovarian.
Ama-ovari anesakhiwo esiyinkimbinkimbi, futhi enza imisebenzi elandelayo:
- ukukhiqiza - ukubunjwa kwamaseli ocansi emzimbeni wesifazane;
- i-endocrine - ama-ovari akhiqizi kuphela abesifazane kepha ama-hormone wesilisa emzimbeni wesifazane, futhi akhiqiza nezinye izinto eziphilayo ezibandakanyeka ngokuqondile ekulawuleni ukusebenza kwazo okujwayelekile.
I-follicle kanjani?
Esikhathini sokwakhiwa kwe-ovarian follicle, izingxenye zangaphandle nezangaphakathi zihlukile. I-follicle ngayinye inaphakathi kwesikhala lapho i-follicular fluid ikhona khona. Kusemagodini akhe ahambile. Futhi, i-fluid iqukethe ama-hormone okuthinta ngokuqondile ukuthuthukiswa kwesifuba, isibeletho, amashubhu, ubulili kanye nesistimu yokuzala ngokuphelele. Lapho kuqala ukuvuthwa kwe-follicle , eyenzeka isikhathi esingu-1 ngenyanga, i-membrane yayo iqhuma futhi iqanda elivuthiwe lishiya isisu esiswini. Le nqubo ibizwa ngokuthi i-ovulation.
