Inhlunu

Ezilwaneni ezincelisayo, isitho sangasese sowesifazane siyingxenye yokunwebeka, yemisipha yegciwane lesitho sangasese sowesifazane. Kubantu, isuka esithweni sangasese iye emgodleni wesibeletho. Ukuvuleka kwangaphandle kwesitho sangasese sowesifazane kuvame ukumbozwa ingxenye ethile yensumpa. Ekugcineni okujulile, umlomo wesibeletho (intamo yesibeletho) ungena ngaphakathi esithweni sangasese. Isitho sangasese sivumela ukuya ocansini nokuzalwa. Ibuye ihambise ukugeleza kokuya esikhathini (menses), okwenzeka kubantu nasezimpungwini ezihlobene eduze njengengxenye yomjikelezo wokuya esikhathini nyangazonke.

Isakhiwo

i-anatomy ephelele

Isitho sowesifazane sangasese somuntu siwumsele onwetshiwe, onemisipha osukela esithweni sangasese somlomo wesitho sangasese sowesifazane uze uye emlonyeni wesibeletho.Ukuvulwa kwesitho sangasese sowesifazane kulele kunxantathu wesibeleko. Unxantathu we-urogenital unxantathu ongaphambili we-perineum futhi uqukethe ukuvuleka komchamo nezingxenye ezihambisanayo zesitho sangasese sangasese. Eduze kwesitho sangasese sangaphezulu, umlomo wesibeletho uphumela ngaphakathi esithweni sangasese sangaphambi kobuso bawo cishe nge-engela engu-90 degree. Ukuvuleka kwesitho sangasese sowesifazane kanye nokuchama kuvikelwe ilebhu.

Uma ungavuswanga ngokocansi, isitho sangasese siyishubhu ewile, kubekwe izindonga zangaphambili nezingemuva ndawonye. Izindonga eziseceleni, ikakhulukazi indawo yazo emaphakathi, ziqinile kakhulu. Ngenxa yalokhu, isitho sangasese sowesifazane esigoqiwe sinesigaba esiphambanweni esimise okwe-H. Ngemuva, isitho sangasese sangasese sangaphakathi sihlukaniswe nengxenyeni yesikhwama se-recto-uterine, isitho sowesifazane esiphakathi nezicubu ezixekethile, kanye nesitho sangasese sangasese ngomzimba ophelele. inkanyiso yesitho sangasese sowesifazane izungeze umlomo wesibeletho sesibeletho, ihlukaniswe izifunda ezine eziqhubekayo (ubufazi besitho sangasese sowesifazane); lawa angama-anterior wangaphambili, ongemuva, ohlangothini olungakwesokudla, nangakwesobunxele.

Ukuxhasa isitho sangasese yimisipha yayo yemigqa ephezulu, emaphakathi, nengaphansi. Ingxenye yesithathu engenhla yimisipha ye-levator ani, kanye nemisipha ye-transcervical, pubocervical, ne-sacrocervical. Isekelwa izingxenye eziphezulu zemigqa yamakhadinali kanye ne-parametrium. Ingxenye yesithathu yesitho sangasese sowesifazane ifaka phakathi i-urogenital diaphragm.Isekelwa yimisipha ye-levator ani nengxenye engezansi yemigudu yamakhadinali.Okungaphansi kwesithathu kusekelwa ngumzimba ophelele, noma i-urogenital ne-pelvic diaphragms. ichazwe njengesekelwa ngumzimba ophelele kanye nengxenye yesikhumba yomsipha we-levator ani.

Ukuvulwa kwesitho sangasese kanye ne-hymen

Ukuvulwa kwesitho sangasese sowesifazane kungasemuva kokuphela kwethala le-vulval, ngemuva kokuvulwa kwe-urethral. Ukuvuleka kwesitho sangasese kuvame ukusitheka nge-labia minora (izindebe zangasese), kepha kungavezwa ngemuva kokubeletha kwesitho sangasese sowesifazane.

I-hymen ulwelwesi lwezicubu oluzungeze noma lumboze kancane ukuvuleka kwesitho sangasese sowesifazane. [10] Imiphumela yocansi nokubeletha kuma-hymen iyahlukahluka. Lapho kwephuke khona, kungaphela ngokuphelele noma izinsalela ezaziwa ngokuthi i-carunculae myrtiformes zingaqhubeka. Ngaphandle kwalokho, ukunwebeka kakhulu, kungabuyela esimweni sayo esejwayelekile.Ngokungeziwe, iculo lingahlushwa izifo, ukulimala, ukuhlolwa kwezokwelapha, ukushaya indlwabu noma ukuvivinya umzimba. Ngalezi zizathu, ubuntombi abunakunqunywa ngokuqinisekile ngokuhlola iculo.

Ukuhluka nosayizi

I-athikili enkulu: Usayizi womuntu wesitho sowesifazane sangasese

Ubude besitho sangasese buyahlukahluka phakathi kwabesifazane abaneminyaka yobudala bokuzala. Ngenxa yobukhona besibeletho odongeni olungaphambili lwesitho sangasese sowesifazane, kunomehluko wobude phakathi kodonga lwangaphambili, cishe u-7.5 cm (2.5 kuya ku-3 in) ubude, nodonga lwangemuva, cishe u-9 cm (3.5 in) ubude Ngesikhathi sokuvuswa kocansi, isitho sangasese sowesifazane siyakhula kokubili ngobude nangobubanzi. Uma owesifazane emi ame mpo, umsele wesitho sangasese sowesifazane ukhomba ohlangothini olubheke phezulu olubuyela emuva bese wenza i-engeli cishe lama-degree angama-45 nesibeletho. Ukuvuleka kwesitho sangasese sowesifazane kanye ne-hymen nakho kuyahluka ngosayizi; ezinganeni, yize iculo livame ukubonakala limise okwenhla, izinhlobo eziningi zingenzeka.
