Iimpawu ze-anatomical kunye nemisebenzi yamanqanda
Njengoko kuchaziwe ngasentla, kwisakhiwo seemfihlo ze-ovary ze-cortical and brain substance. Iyokuqala iqulethe iipolisi eziprayimari, ezisekondari, eziphakamileyo, kunye nemigqomo emhlophe nephuzi.
Nangona kunjalo, ngokuphuhliswa kwezilwanyana, utshintsho luya kwenzeka. Ngoko, phambi kwesi sifo, isakhiwo sezitho zitshintsha, kwaye ke bathetha nge-polycystic ( multitifollicular ) ovaries. Kule meko, kukho ukwanda kwenani lazo zombini.
Ngokwakheko lwe-medulla ye-ovary yowesifazane, eyenziwa ngamathambo axhumeneyo, imithwalo yegazi, izixhobo zamatye, kunye neentambo ze-epithelial azifumaneki. Ngokuqhelekileyo kubangelwa ukuphuhliswa kwentsholongwane leyo njenge-cyst ovarian.
Ama-ovane anesakhiwo esiyinkimbinkimbi, kwaye enze imisebenzi elandelayo:
- ukuvelisa - kukubunjwa kweeseli zesini kumzimba wesetyhini;
- i-endocrine - ama-ovari akhiqizi nje kuphela amabhinqa kodwa kunye namahomoni angamadoda kumzimba wesetyhini, kwaye adibanisa nezinye iinxalenye ze-bio-ezithatha inxaxheba ngqo kwimimiselo yazo yokusebenza ngokuqhelekileyo.
Njani ulandelelwano?
Kwi sakhiwo se-ovarian follicle, izithuba zangaphandle nezangaphakathi ziyahlukana. I-follicle ngayinye inaphakathi kwendawo apho i-follicular fluid ikhona khona. Kulo mavolisi akhe ahlambulukileyo. Kwakhona, i-fluid iqulethe i-hormone echaphazela ngqo ukuphuhliswa kwebele, isisu, iibhubhu, isondo kunye nenkqubo yokuzala ngokupheleleyo. Ngokuqala kokuvuthwa kobugqwetha , obwenzeka ngexesha eli-1 ngenyanga, i-membrane i-bursts kunye neqanda elivuthiweyo liphuma kwisisu esiswini. Le nkqubo ibizwa ngokuba yi-ovulation.
