Zygote ces undergoes cleavage division. Lub cleavage tshwm sim nyob rau hauv qhov nce ntawm tus naj npawb ntawm hlwb tab sis qhov loj tseem zoo ib yam li cov qe fertilized. Morula nrog 16 cell faib mitotically thiab ua 32 cev . 32 celled theem yog hu ua blastula thiab tag nrho cov hlwb hauv blastula yog tib qhov loj li zygote.

Kuj nug, lub npe ntawm zygote nrog 32 hlwb yog dab tsi?

Thaum lub zygote ua muaj 16to 32 blastomeres nws yog hu ua "morula." Cov no yog cov theem ua ntej hauv lub embryo pib tsim. Thaum qhov no pib, microtubules nyob rau hauv lub morula's cytosolic khoom nyob rau hauv lub blastomere. hlwb tuaj yeem txhim kho ua haujlwm tseem ceeb hauv daim nyias nyias, xws li cov twj sodium.

Ib tug kuj nug, puas yog ib lub pob ntawm 32 hlwb tom qab cleavage tshwm sim? Lo lus teb raug rau qhov sau rau hauv qhov khoob yog "morula." Qhov no yog qhov tshwm sim ntawm lub cleavage thiab forms a pob ua 8to 32 cev . Cleavage tshwm sim thaum thawj theem ntawm kev loj hlob ntawm lub embryo thaum lub zygote tawg mus rau ntau tus neeg me hlwb los ntawm cov txheej txheem ntawm cell kev faib.

Kuj Paub, muaj pes tsawg lub hlwb nyob hauv Blastula?

100 cell

8 cell theem yog dab tsi?

8 - Cell Embryo (Mrl) Lub 8 cell theem (Qhov tseeb suav nrog 6-12 hlwb ) tsim los ntawm hnub 3 ntawm tib neeg embryonic kev loj hlob, thiab suav nrog kev txuas ntxiv ntawm cov txheej txheem ntawm embryonic genome activation (uas yog pib ntawm 4- 8 - cell theem ntawm tib neeg embryo), ua rau lub morula.
