Umsebenzi wesisu - emva kokuba umanyolo ube yindawo lapho umntwana eyokhula khona futhi ahlakulele, ngoba lesi sibeletho singaphezu kwesiguli ngaphezu kwentamo yaso, futhi ukuthola isibeletho esiswini esiswini ngemuva kwamathambo esifuba sikuvikela ekulimazeni okungenzeka.
Uphi isibeletho somfazi?
Lapho i-vagin iphela, umlomo wesibeletho utholakala - lena yingxenye yayo engezansi ngesimo se-cylindrical tube esinomzila omncane ngaphakathi. Lesi siteshi sibizwa ngokuthi umlomo wesibeletho, sinama-oval kunabesifazane abangenalutho futhi sinomumo obunjwayele kulabo ababelethayo. Ngalesi siteshi, i-sperm ingena emgodini we-uterine, iboshelwe ipulaki, elivame ukuvala umsele. Zenza ukukhishwa ngesikhathi sokuya esikhathini.
Ngaphezulu kwesibeletho sitholakala emzimbeni wayo, ngokuvamile ifomu eliphakathi kwe-pear, elitholakala ngemuva kwesigcawu, phambi kwe-rectum esithombeni esincane. Iqukethe izingqimba ezintathu:
- i-endometrium (ungqimba lwama-mucous) - ungqimba lwangaphakathi lwesigamu se-uterine, lapho iqanda elikhuliswe khona linamathele ngesikhathi sokukhulelwa;
- i-myometrium (ungqimba wamascle) - ungqimba ophakathi ohlinzeka ngezingqinamba zobisi;
- i-perimetry (ungqimba lwe-serous) - i-leaflet ye-peritoneum efaka isisu kusuka ngaphandle.
Emzimbeni wesibeletho singaphansi, lapho ukuvuleka kwama-tubespian tubes kuvulwa. Esikhathini sesisu, ama-anterior kanye nama-posterior angaphansi kwe-peritoneum aguquke, lapho i-ligament yesibeletho isungulwa khona, lapho kutholakala khona amashubhu omzimba (emigqeni emikhulu yesibeletho). Ukwengeza, lesi sibeletho sigxilwe yisiguli esiyindilinga nesiguli esiswini. Isibeletho sisezindaweni ze-geometri ye-pelvis encane, ukuhamba kwayo kungenzeka ngezinkinga futhi ngenxa yezinqubo zokuvuvukala ku-pelvis encane.
Izici zesibindi
Kukhona umehluko lapho isisu sikhona khona intombazane kanye nowesifazane, kanye nokukhulelwa. Kubesifazane abangenayo i-nulliparous, ayikho ngaphezu kwethambo le-pubic futhi ubude bayo abuke ngaphezu kuka-8 cm, ububanzi bungaphezu kuka-4 cm, ubukhulu bungaphezu kuka-3 cm.
Ngesikhathi sokukhulelwa, isisu sikhula futhi sikhule ngesayizi. Ngendawo yesikhumba nesisekelo sayo ngesikhathi ukhulelwe, ungakwazi ukunquma isikhathi. Ukuphakama kwesibindi ngamasentimitha cishe kufana nesikhathi sokukhulelwa kowesifazane emasontweni. Ngemuva kwamaviki angu-13-14, lesi sibeletho sikhuphuka ngaphezu kwe-pubis, uma ukuphakama kwesibindi sesimiso ngaphezu kwe-symphysis kuhluke esikhathini sokubeletha okungaphezu kuka-3 cm, khona-ke umuntu angacabanga nge- pathology of pregnancy (isib. Polyhydramnios, FGRS).
Ngemuva kokubeletha, lesi sizalo sineminwe engaphansi kwe-inkaba engama-4, kodwa ngokushesha sehlehla futhi sibuyele esayizi evamile emva kwezinyanga ezingu-1-2.
