Umthambo womzimba ubizwa nangokuthi i-umbilical cord (Latin funiculus umbilicalis). Umsebenzi wayo ukuxhuma umbungu, bese ubhekana nomzimba womama. Ubude bomthamo womuntu kumuntu ufinyelela ku-50 - 70 cm noma ngaphezulu. Lokhu kuvumela ukuthi ingane ihambe emgodini we-uterine. Emntwaneni osanda kuzalwa, intambo ye-umbilical ingaba ngu-2 cm ubukhulu. Ngaphandle kunamandla, okufana ne-hose yensiza yensiza enezinhlayiya ezibushelelezi nezicwebezelayo.
Uvela kuphi intambo yomzimba?
Intambo yomzimba ihlanganiswe ne-placenta phakathi nendawo noma eceleni. Kwenzeka ukuthi intambo yomzimba ijoyina izitho zangasese, kanti ingafinyeleli i-placenta ngokwayo.
Kuvela nini intambo yomzimba?
Kuyaziwa ukuthi, kusukela emasontweni amabili okukhulelwa, sekuqala ukwakha, futhi ezinyangeni ezingu-2 sekukhule ngokugcwele usayizi ojwayelekile. Kodwa, kukhona "kanatiki" kuphela kufika ku-40 cm ubude, noma ukufinyelela kumamitha angaphezu kwangu-1! Ukungahleleki okunjalo kwendwangu yomzimba kuyimfuneko yokuhlanganisa amafindo nezinye izinkinga.
Ama-anomalies ombilical
Okubaluleke nakakhulu yi-anomalies embilical ehambisana nokungahambisani nobude bayo: intambo ende noma emfushane kakhulu, izizathu zokubonakala kwezimpikiswano ezinjalo aziwazi kahle.
Ngomumo omude omude (70-80 cm), okwenzeka kaningi kakhulu, ukubeletha kungahamba ngaphandle kwezinkinga. Noma kunjalo, kungenzeka ukuthi ihlanganiswe izingxenye ezahlukene ze-fetus, engenzeka ngenxa yokunyakaza okusebenzayo kwengane. Ukumangalelwa kungaba okukodwa kanye nokuningi. Kukhona nesichazamazwi esiqinile-netgo. Wonke amacala kufanele abe ngaphansi kokuqondiswa okudokotela kadokotela wakho.
Intambo encane ye-umbilical, ngaphansi kuka-40 cm, engavamile ukuba ngu-10-20 cm, ingabangela ukubonakala kwesimo esingalungile se-fetal. Ngesikhathi sokubeletha, i-pathology efana ne-short umbilical cord ngokuvamile iyisizathu sokuthi kungani ingane ihamba kancane kancane emgodini wokuzalwa, futhi i-placenta iqhubekela phambili ngaphambi kwesikhathi.
Intambo encane yomzimba ingabangela ukuphulukiswa okuqhubekayo kwilonda elimnyama. Ngakho-ke, kufanele uyiqaphelisise.
Kuphi emva kokuzalwa kuyi-cord umbilical?
Ngokuvamile, intambo yomntwana osanda kuzalwa ingokwalabhulali ekhethekile lapho kucwaningwa khona ucwaningo. Manje sekuye kwaba yindabuko ukunikeza isikhungo somzimba ezindaweni zokugcina zesitokisi se-stem, lapho lawa maseli akhishwa khona emthonjeni futhi agcinwa kulo lonke ukuphila komuntu. Ezimweni ezijwayelekile, intambo yomzimba ilahlwa esibhedlela.
