ʻEpekema lapaʻau Ke kumu hoʻohālike anatomical hāpai ʻana o ka fetal Kaʻina hana hoʻomohala Embryo 10-ʻāpana set keʻena hoʻokolohua haukapila

Ua hoʻonohonoho ʻia nā hiʻohiʻona 10 e hōʻike i ka pilina ma waena o ke kaʻina hana hoʻomohala o ka fetus a me ka uterus i ka hāpai ʻana o ʻOkakopa. Ua kapa ʻia ka hua he hāpai a i ʻole i hoʻoulu ʻia i loko o 2 mau pule ma hope o ka hoʻoulu ʻana; ʻO nā pule 3-8 ma hope o ka hoʻoulu ʻana ua kapa ʻia he embryos; Mai ka hopena o ka pule 8, ua kapa ʻia ʻo ia he fetus; 8 pule; ʻO ka embryo ma kahi o 3cm ka lōʻihi a ua hoʻomaka e lawe i ke ʻano kanaka, me ke poʻo nui loa, nā maka i ʻike ʻia, nā pepeiao, ka ihu a me ka waha. Hiki ke ʻike ʻia ka hoʻokumu mua ʻana o ka puʻuwai a me ka pulsation e ka nānā ʻana o ka ultrasound. I nā pule 12, ʻo ka fetus he 7 ~ 9cm ka lōʻihi a he 20g ke kaumaha. Ua hana ʻia ka orthogonia exogenous, aia ka hana nāwaliwali i nā lālā, a ua ʻike ʻia nā kikowaena ossification i ka hapa nui o nā iwi. I nā pule 16, ʻo ka fetus ma kahi o 10 a 17cm ka lōʻihi a he 100 a 120g ke kaumaha. He ʻili ʻulaʻula, laumania a moakaka hoʻi me kahi liʻiliʻi o ka lauoho vellus. ʻO ka hoʻomohala iwi hou aʻe, hiki i ka nānā ʻana o X-ray ke ʻike i ke aka o ka iwi, hiki i ka mea hoʻopololei waho ke hoʻokaʻawale i ke kāne a me ka wahine. Hiki i ka nānā ʻana o ka ʻōpū ke lohe i ke kani o ka puʻuwai o ka pēpē, hiki i nā wahine hāpai ke manaʻo i ka neʻe ʻana o ka pēpē. I nā pule 20, he 18 ~ 27cm ka lōʻihi o ke pēpē, he 280 ~ 300g ke kaumaha, he ʻulaʻula ʻeleʻele ka ʻili, ua emi ka mālamalama, he momona ko ke kino o ka pēpē, ʻo ke poʻo o ka pēpē he 1/3 o ke kino, ulu ka lauoho, a hoʻomaka ka hana ale. 24 pule ʻo ka lōʻihi o ke kino o ka pēpē he 28 ~ 34cm, kaumaha 600 ~ 700g, hoʻomaka ka momona subcutaneous e waiho, nā wrinkles o ka ʻili. I nā pule 28, he 35 ~ 38cm ka lōʻihi o ke pēpē a he 100 ~ 1200g ke kaumaha. He lahilahi ke kino holoʻokoʻa, he ʻulaʻula ka ʻili, aia ka momona o ka pēpē ma ka manamana lima (manamana wāwae) ʻaʻole hiki i ka manamana lima (manamana wāwae) ka hopena. I nā wahine, aia ka labia majora i ka labia minora a me ka clitoris, a i nā kāne, ua iho nā testicles i ka scrotum. Ma muli o ka emi ʻana o ka momona subcutaneous, nā wrinkles o ka maka, e like me ke kanaka ʻelemakule. Inā hānau ʻia, hiki iā lākou ke uē, ale, a hoʻoneʻe i ko lākou mau lālā, akā ua nāwaliwali lākou a pono ke mālama kūikawā e ola ai. ʻO ka pēpē 32-pule he 40cm ka lōʻihi, he 1500 ~ 1700g ke kaumaha, he ʻulaʻula ʻeleʻele ka ʻili, ua hāʻule ka lauoho maka, a hiki ke ola ma hope o ka mālama pono ʻana. I nā pule 36, he 45 ~ 46cm ka lōʻihi o ka pēpē a he 2500g ke kaumaha. ʻO ka momona subcutaneous, nalowale nā ​​wrinkles maka, ua hiki ke kui manamana lima (manamana wāwae) i ka manamana lima (manamana wāwae). Ma hope o ka hānau ʻana, he manawa kūpono ke ola ʻana o ka ʻūlū ʻana a me ka omo ʻana. Ua oʻo ka pēpē i nā pule 40, me ka lōʻihi ma kahi o 50cm a me ke kaumaha ma kahi o 3000 ~ 3300g. He poni ka ʻili, ua ulu maikaʻi ka momona subcutaneous, ua emi ka hapa nui o ka pēpē, a he 2 ~ 3cm ka lōʻihi o ka lauoho. Ua hala ke kui o ka manamana lima ma luna o ka piko o ka manamana lima. Neʻe ikaika nā lālā, ʻūlū nui, reflex omo ikaika. Hoʻonui mālie ka lōʻihi a me ke kaumaha o ke kino o ka pēpē me ka malama hāpai, i mea e maʻalahi ai ka hoʻomanaʻo, hoʻohana pinepine ʻia ke ʻano hana e helu ai: ma mua o 20 pule o ka lōʻihi o ka hāpai = ka huinahā o ka helu o nā mahina hāpai (cm), ma hope o 20 pule o ka lōʻihi o ka hāpai = ka helu o nā mahina hāpai ×5 (cm).
