Usayizi Biparietal.

Ukuze umuntu ngamunye akukho ebaluleke ngaphezu impilo yomkhaya wakhe kanye namalungu ayo. Ngakho-ke, ukunakwa okukhulu ikhokhelwa namuhla nokuhlinzekwa ngokunakekelwa kwezempilo okusezingeni. Ikakhulukazi lo mbuzo uyafaneleka maqondana yokuhlela nokuphatha yokukhulelwa. Bheka intuthuko yayo yenziwa ukuze balondoloze futhi bakhuthaze umthetho impilo kumama nele-fetus.

Namuhla, omningi emhlabeni Esti ngezindlela ezahlukahlukene nezindlela ukuqapha inqubekelaphambili yokukhulelwa. Phakathi kwabo, ngokuvamile ezisetshenziswa ultrasound uphethwe. Ephathelene eyamukelayo Ukusabalala lokuqala ochereds harmlessness isifundo esinjalo nokuphepha yayo ukuze sibe nomzimba ezikhulayo.

Ngezinye US izinkomba ezisemqoka esiswini nasesifubeni ubukhulu amaseli fetus obuphelele kunawo wonke futhi isixazululo biparietal. Lezi zinkomba kukhona ulwazi kakhulu futhi ube njani embungwini kushintsha ophelele.

Kuyini ubukhulu biparietal? Kulinganiselwa imaging amagagasi echo ngehora lesithathu ubuchopho ventricle. BDP ephawula ibanga langempela phakathi kwezindonga ezimbili eziphikisanayo (wabuka elingaphandle parietal amathambo Yekhanda). Lo sayizi isici eqondile Usayizi ikhanda. Isetshenziselwa ukuhlola kungenzeka ukudlula ikhanda ngokusebenzisa emgudwini wokuzala.

Ngaphezu kwalokho, isilinganiso ibanga phakathi wabuka yangaphandle engaphelele kanye occipital ithambo phakathi izindawo zabo akude.

Biparietal fetus nekhanda kunqunywe trimesters sokukhulelwa wesibili nowesithathu. Lolu uphawu olukhulu lokuthi eyinhloko ukuthuthukiswa umbungu. Kungani kusetshenziswa?

Iqiniso ukuthi ubuchopho (ukwandisa ngobukhulu Yekhanda) Kungenzeka ngqo abonisa ukuthuthukiswa evamile noma okungavamile isimiso sezinzwa.

Isici esiphawulekayo lokhu inkomba kuyinto ukubambezela izinguquko esikhathini sokugcwaliseka kwaso umbungu. Ngakho, usayizi biparietal, noma kunalokho izinga yayo kwenyuswa 14-15 ngesonto yokukhulelwa kuyinto amamilimitha angu ezine ngesonto. Lwathi luphela izinga sokukhulelwa ukwanda index ancipha kakhulu futhi 1.3 kuphela mm ngeliviki.

usayizi Biparietal ikhanda fetus abakwazi kuphela ukwahlulela ukuthuthukiswa umbungu, kodwa futhi siyisisekelo ngqo ekutholeni isikhathi yokukhulelwa (ngokungabi bikho ezinye izinketho). Kulokhu, lo BDP kuyinto walandisa ubukhulu Fronto-occipital, futhi kuba sezithonyiwe kwi Inkomba entsha - index ekhanda.

Kumele kukhunjulwe ukuthi ulwazi sokukhulelwa ivumela ilungelo ukuhlola izinguquko kungokwemvelo futhi sokugembula. Phakathi nalokhu kwesibili, kakhulu ngokuvamile - kwesikhathi noma ukukhulelwa perenashivanie.

Biparietal kuchazwe usayizi futhi ukuze ukhethe imodi oyifunayo kwezidingo (isitho sangasese somuntu wesifazane noma ngokungena Ukubeletha). Uma kukhona i-data esekhadini ubukhulu ikhanda wengane kanye nolwazi mayelana nobukhulu nesimo izindlela umama lokuzalwa BakaJehova sikuhlaziye ukuhlanganisa Ubukhulu. Uma emgudwini wokuzala ayisesemikhulu noma ikhanda fetus likhulu kakhulu (elibangela ingozi enkulu yokulimala kokubili umama nengane ngesikhathi sokuzalwa) isinqumo senziwe ekusebenzeni womama.

Kuye ngokuthi yiziphi ubukhulu (ibanga phakathi izingxenye yangaphandle noma kwangaphakathi phakathi amathambo parietal) kuchazwa, zikhona ezinye umehluko nokuchazwa imiphumela.

Ngakho, ukuze sithole kwengane esiswini yomzimba kukhona qualitative, okusheshayo, futhi okubaluleke - inqubo ephephile. Ukunqunywa ubukhulu biparietal ikhanda fetus, kanye nezinye izinkomba namuhla kabanzi lisetshenziswe wokubelethisa nezifo zabesifazane.
