I-cervix iyisitho esixhuma isisu ngesisu futhi senza imisebenzi ethile. Umsebenzi wayo oyinhloko uyisivikelo, ngakho ngenxa ye-yang yangaphandle evaliwe ivimbela ukungena kwezitshalo kusuka kwesifazane ukuya esibelethweni. Umlomo wesibeletho uhlanganisa i-pharynx yangaphakathi neyangaphakathi, kanye nokuvula okuxhuma isibeletho nge-vaginal - umsele womlomo wesibeletho. Ubude obujwayelekile bomlomo wesibeletho ngesikhathi sokukhulelwa kufanele okungenani kube ngu-3 cm, ngokunciphisa ubude bayo, khuluma ngengozi yokukhipha isisu futhi unqume ukuthi uzohamba yini ukwelashwa noma ukwelashwa okwelashwa.
Ubude bomlomo wesibeletho ekukhulelweni
Njengoba sekushiwo kakade, umlomo wesibeletho wenza umsebenzi wokuzivikela, ikakhulukazi ngesikhathi sokukhulelwa. Ezikhathini zokuqala, kuba lukhulu kakhulu, kudala ipulaki elincane, elivimbela ekungeneni kokutheleleka emgodini we-uterine. Ubude bezingxenye ezivaliwe zomlomo wesibeletho ngaphambi kweviki lama-36 lokukhulelwa kufanele okungenani kube ngu-3 cm. Isibeletho sombelevuza singakunqunywa isikhathi esingakanani ngesifo somzimba ngesikhathi sokuhlolwa kwangaphakathi kwe-obstetric kanye nokuhlolwa kwe-ultrasound.
Ubude besibeletho ngesonto
Ucwaningo olwenziwe ngokukhethekile luveze ukuthi kuncike ekutheni ubude bomlomo wesibeletho buyiminyaka engakanani. Ngakho-ke, ubude bomlomo wesibeletho esikhathini samasonto angu-10-14 okujwayelekile buhluka phakathi kwama-35-36 mm. Emasontweni angu-15-19 ubude bomlomo wesibeletho buyi-38-39 mm, emavikini angu-20-24 - 40 mm, nasemasontweni angu-25-29 - 41 mm. Ngemuva kwamasonto angu-29, ubude bomlomo wesibeletho buyancipha futhi emavikini angu-30-34 kakade sekuyi-37 mm, futhi emavikini angu 35-40 - 29 mm. Njengoba ubona, ngemuva kwamasonto angu-29 umlomo wesibeletho uqala ukulungiselela ukuzalwa okuzayo. Ngemuva kwamaviki angama-36 wokubeletha, umlomo wesibeletho uqala ukunciphisa ngaphambi kokuzalwa , ukhululeka, i-pharynx yayo iqala ukuqala futhi idlulise iphuzu lomunwe. Ubude bomlomo wesibeletho ekuzalweni kabusha emasontweni angu-13-14 kufanele kube ngu-36-37 mm.
Ubude bomlomo wesibeletho ngaphambi kokubeletha
Masinyane ngaphambi kokubeletha, i-cervix ivuthwa, ebizwa ngokuthi "ukuvuthwa." Intamo ithambile, igxile (ephakathi nendawo ye-pelvis encane), ubude bayo buyancipha kuya ku-10-15 mm, kanti i-pharynx yangaphakathi ihamba nge-5-10 mm (idlula isihloko somunwe noma umunwe owodwa). Kukhona ukululaza kwengxenye yangaphakathi yentamo, kuba, njengokungathi, isandiso sesigaba esingaphansi kwesibeletho. Ubude bomlomo wesibeletho ngesikhathi sokubeletha buyancipha ngokushesha - buvuleka, ukuze ingane ikwazi ukudlula emgodini wokuzalwa. Ekuqaleni komsebenzi kukhona ubuhlungu obunzima emathunjini, okuthiwa yi-contractions. Ngesikhathi sokuqhekeka, inkontileka ye-muscle fibers futhi ngesikhathi esifanayo umlomo wesibeletho uvula. Lapho ukuvulwa komlomo wesibeletho kufinyelela ku-4 cm, umsebenzi wezomsebenzi usungulwa futhi kuvulwa okulandelayo ku-1 cm ngehora.
Ubude bomlomo wesibeletho uma usongelwa ukukhipha isisu
Ukunciphisa ubude bomlomo wesibeletho ongaphansi kuka-30 mm emasontweni angu-17-20 okukhulelwa kuthathwa njengokungaqiniseki kwesifo somlomo wesibeletho . Ngalesi sifo, ubude bomlomo wesibeletho bunganciphisa kancane kancane, futhi ingane ihlalele ekuphumeni, okuyinto
Sihlolile ukuthi yini okufanele ibe ubude bomlomo wesibeletho ngesikhathi sokukhulelwa nangaphambi kokubeletha. Futhi futhi wazi kangcono nalesi sifo sokuzivikela njenge-istmiko-insufficiency, engasho ukuthi ukunciphisa ubude bomngcwabo womlomo ongaphansi kuka-29 mm.
