Kuyini usayizi we-biparietal?
Ubuningi biparietal yekhanda lomntwana (noma i-BDP ye-fetus), itafula lapho noma yimuphi udokotela onguchwepheshe wezocwaningo lwe-ultrasound kufanele azi, ingenye yezinkomba ezinembile kakhulu zomnyaka wokuthoma. Yinqunywa imiphumela ye-ultrasound. Inani eliphakeme lokufundisa le nkhomba liyabonakala emavikini angu-12-28 okukhulelwa.
I-BDP - ibanga eliphakathi kwemikhawulo yangaphakathi neyaphandle yamathambo e-parietal, okungukuthi, umzila oxhuma izingxenyana zangaphandle zamathambo e-parietal. Kumele kudlule i-thalamus. Lona okuthiwa "ububanzi" bekhanda, elilinganiswa kusukela ethempelini kuya ethempelini eduze kwe-axis encane.
Nganoma yisiphi isikhathi sokubeletha, kunenani elithile lezinkomba ezicatshangelwe ngendlela evamile. Njengoba ukukhulelwa kukhula, lesi sibonakaliso sanda futhi, kodwa ekupheleni kwesisu sokukhula kwesilinganiso saso sinciphisa kakhulu. Ukungaphambuki emithethweni yokulinganisa eyamukelekile kuvame ukuholela ekuphambeni kwemiphumela etholakele, ngenxa yokuthi isikhathi sokukhulelwa sinqunywe kahle.
Ithebula le-biparietal usayizi wekhanda lesisu
Ngaphansi kwetafula le-BDP. Ikhombisa izinkomba zenkomba kusukela emavikini angu-11 kuya kwangu-40 okubeletha, ngoba ngalesi sikhathi izazi ze-ultrasound zilinganisa esifundweni ngasinye.
Le nkomba akufanele ilinganiswe ngokuzimela, kodwa kanye nobukhulu obungaphambi kwendawo-occipital. Zilinganiswa ngendiza eyodwa futhi ziyahlukahluka ngokuqondile nesikhathi sokuthuthukiswa kwe-intrauterine. Ukuze uthole ngokunemba okuphelele, ukuzungeza kwesisu nesilinganiso sethanga nakho kulinganiswa.
Ukulinganisa kwe-BDP kuvumela ukukhomba ukukhathazeka okuthile ekuthuthukiseni umntwana, okungukuthi: ukulimala kwe-intrauterine ukukhulelwa, i- hydrocephalus, isisindo esiningi ngokweqile (uma lokhu kudluliwe) noma i- microcephaly (uma engekho). Kulesi simo, imiphumela yezinye izilinganiso zicatshangelwa.
