Yiziphi izinguquko iqanda elibhekene nalo ekujikelezeni kokuya esikhathini?
Njengoba sekuyaziwa, amasondo omzimba wabesifazane asungulwa esigabeni sokuthuthukiswa kwe-intrauterine. Inyanga zonke, lapho kuqala ukukhulelwa, iqanda lishiya i-follicle yokukhulelwa. Ngokuvamile umjikelezo owodwa emgodini wesisu ungahamba kumaqanda amabili.
Ngokuqondene nesakhiwo sangaphandle, i-ovumkazi yesifazane ibukeka njengento encane eyenziwe nge-anatomical form-spherical. Ngaphandle limbozwe igobolondo elikhulu, elivikela okuqukethwe kwangaphakathi kanye nomsuka kusuka emathonyeni angaphandle angalungile.
Uma emzimbeni wesifazane kukhona inqubo enjengokuvuthwa, iqanda likhula kancane futhi libukeka "livuvukale". Lokhu kunciphisa igobolondo langaphandle. Lokhu kuyadingeka ukuze kwandiswe ukuguguleka kwebhubhane lamasilisa amagciwane ngesikhathi sokukhulelwa.
Uma isikhathi socansi sihambisana nokuvuthwa, amathuba okukhulelwa aphezulu. Ngemuva kwalokho, ukubonakala kwesitholi sezesini kuyashintsha. Iqanda elikhulelwe libukeka lifana nanjengaphambili, kodwa i-membrane yangaphandle iphinde ihlanganiswe. Ngesikhathi esifanayo, ngaphakathi kweseli ngokwayo, kungenzeka ukubona i-nuclei engu-2 (1 kusuka ku-spermatozoon) usebenzisa i-microscope ye-electron, ehlanganisa futhi iqale ukwahlukanisa.
Kwenzekani eqanda emva kokuvuthwa?
Uma ukufaka umquba kungenzeki, khona-ke kuthiwa usuku olulodwa ngemva kokukhululwa kweqanda. Wonke ama-organelles ayo, kanye nama-membranes, aphuma, exubana negazi lokuya esikhathini kanye nezinhlayiya ze-endometrium ye-uterine. Ngakho-ke, uma sikhuluma ngendlela iqanda libukeka ngayo njalo ngenyanga, kufanele kuqashelwe ukuthi manje, njengoba kunjalo, akusekho. Kodwa-ke, ngesikhathi esifanayo emaqanda ama-ovari i-germ cell entsha ivuthwa ngaphakathi kwe-follicle, ekhulayo kancane kancane ngobukhulu.
