Amabele athuthuka ekuqaleni kokuthuthukiswa kombungu, ikakhulukazi ngesonto lesine lesikhathi sokubeletha. Yini eyaziwa ngokuthi imigqa yobisi ivela maduzane ngemuva, ngasekupheleni kwesonto lesithupha lokuthuthukiswa. Lezi zigodi ziphuma phansi emgodini kuya emaceleni zombili zomzimba. Njengoba amabele aqhubeka ethuthuka, le migqa ekugcineni ihlukana, ngokuvamile ngesonto lesishiyagalolunye.
Kodwa-ke, ngezikhathi ezithile, imigqa yobisi izoqhubeka futhi ingaxhunyaniswa nezicubu zesifuba esengeziwe kanye nezinsipho ezingaphezulu.
I-Breast Early Development ingaholela kanjani kuma-Nipples engeziwe?
Ekuthuthukiseni komuntu okuvamile, imigqa yobisi, ingxenye enkulu, iyanyamalala. Kwezinye izimo, kungase kube khona izicubu ezincelisayo ezingaphezulu kwamanye amazwe-ama-nipples engeziwe namabele, okubizwa nangokuthi i-polythelia ne-polymastia, ngokulandelana-okungaba yinkomba yokuthi imigqa yobisi ayizange ihlukane ngokuphelele.
Ama-nipples angeziwe, uma axhunyiwe nama-glands, angakwazi ukukhiqiza ubisi lwebele ngemva kokukhulelwa. Ngezinye izikhathi kuthiwa ama- nipples okutholakala noma ama- nipples wesithathu , ngokuvamile avame ukufana nama-moles noma ama-freckles futhi ahlale engaxhumano namathisamu webele noma amakhekhe ebisi.
Amanye Amagama Ajwayelekile Ngezingxube Ezengeziwe
Ngaphandle kwegama elithi polythelia, ingono yokufinyelela, ne-ingono yesithathu, ungase uzwe okulandelayo:
- Ingono enkulu kakhulu
- Ingono yokufinyelela
- Ingono yesithathu
- I-Vestigial nipple
- Ingwenya yomlingo
Ubani Okungenzeka Kakhulu Ukuthola Ingono Engeziwe?
Bobabili abesilisa nabesifazane bangathuthukisa ingono eyengeziwe. Kuyinto engajwayelekile evamile ukuthi ngezinye izikhathi kwenzeka emindenini kodwa kungenzeka ukuthi ikhule ngokungahleliwe.
U-Anne Boleyn, umkami weNkosi uHenry VIII waseNgilandi, kuthiwa ube nesibindi sesithathu.
I-Scaramanga, i-Bond ye-Bond eyaziwa kakhulu, yayinombono wezinsiza futhi lokhu okwenza kube lula ukuyikhomba. Ososayensi baqamba igoli likaScaramanga emva kwakhe; yilezi zakhi zofuzo ezikhiqiza iphrotheni okuthiwa i-Neuregulin-3 (NRG3), ehlinzeka isignali kuma-embryonic ewazisa ukuba abe ngamaseli asebele.
Ama-Nipples afinyelelekayo, i-Breast Cancer, nezinye izimo
Uma une-nipples eyodwa noma ngaphezulu, ungase uzibuze ukuthi lokhu kwandisa ingozi yomdlavuza webele . Noma yiziphi izicubu zesifuba onayo, kungakhathaliseki ukuthi zivela endaweni evamile noma kwenye indawo, zisengozini ezifweni ezifanayo ezingathinta izicubu zesifuba ezivamile.
Ukutholakala kwama-nipples engeziwe ngezinye izikhathi kuhlangene nokukhubazeka kwenhliziyo nesifo sezinso. Isifo se-Paget se-ingono singase sibonakale endaweni yakho yokulima (ukuphela okuphansi kwemigqa yobisi) lapho kuthiwa i-extramammary isifo se-Paget (EMPD).
Nginakekela Kanjani Ama-Nipples Angeziwe?
Kubantu abaningi, izinsipho ezingaphezulu ziyingozi futhi ngeke ziphawulwe. Kodwa uma uyazi ukuthi une- nipple eyengeziwe , ubone udokotela wakho uma iguqula, ichithe , noma iveza uhla noma ukuqhuma. Uma une-nipple eyengeziwe futhi ikukhathaza, ingasuswa ngokuhlinzwa, njengemvukuzane.
Imigqa yobisi , eyaziwa yi-technical term term ventral epidermal ridges, yizibikezelo ezigulini zezinyosi kanye nezinsipho.
Akuzona zonke izinguquko zezinyosi ezikhombisa umdlavuza webele, kodwa ukwazi ukuthi yiziphi izinguquko ezilindelekile nokuthi izibonakaliso zezifo zibaluleke kangakanani empilweni yakho yebele.
