The 8-Week Embryo

Chapter 30   8 Weeks: Brain Development

Usbuuca 8da maskaxdu aad bay u horumarsan tahay waxayna tahay ku dhawaad miisaanka dhan ee jirka embriyaha barkiis.

Koriimadu waxay ku socotaa xawli xad-dhaaf ah.

Chapter 31   Right- and Left-Handedness

Usbuuca 8da, 75% embriyeyaasha waxa ka muuqda awood dheerada ee gacan-midigle. Waxa haray waxay ugu qaybsan yihiin si isle'eg awood dheerada ee gacan-bidxle iyo kala doorbidid la'aan. Tan waa daliisha ugu horreysa ee dhaqan gacan ku midigle ama bidixle ahaansho.

Chapter 32   Rolling Over

Buugaagta takhtaridda carruurta waxay tilmaamayaan karti "is-gaddin" inay muuqato 10 ama 20 usbuuca dhalashada kadib. Laakiin, isku-duwiddaan cajiibka ah waxay ku muuqataa xilli sii hore bii'adda leh quwad-jiidasho dhul oo hooseysa ee koleyga amniyon-ka dareeruhu-ka-buuxo la'aanshaha awoodda loogu baahan yahay oo kaliya si looga guuleysto quwad-jiidashada dhulka sarreysa ee minka dibeddiisa ayaa ka horistaageysa dhallaanka inuu is-geddiyo.

Embriyuhu wuxu noqonayaa mid sii firficoon jismi ahaan xilligaan gudahiisa.

Dhaqaaqu wuxu noqon karayaa aayar ama dhaqsi, fardi ama soo-noqnoqod, fal iska dhaca ama ka jawab-celin automaatik ah.

Madax warejin, qoor taagid, iyo ku taabasho gacanta wajiga waxay dhacaan marar ka sii badan.

Taabashada embriyaha waxay keeneysaa indho dabid, dhaqdhaqaaq qalka, dhaqaaq qabsasho, iyo suul fiiqid.

Chapter 33   Eyelid Fusion

Usbuuca 7da iyo 8da dhexdooda, baalalka isha ee kore hoose si dhaqsi ah bay ugu koraan indhaha korkooda dhan ahaan bayna isqabsadaan.

Chapter 34   "Breathing" Motion and Urination

Inkastoo uusan minku lahayn hawo embriyuhu wuxu muujinayaa dhaqaaq neefsasho kala go'aysa usbuuca 8da.

Xilligan, kelyuhu waxay sameynayaan kaadi oo lagu sii deynayo dareeraha amniyon-ka.

Embriyaha labka ah, xiniinyaha koraya waxay bilaabayaan inay sameeyaan siina-daayan testosteroon.

Chapter 35   The Limbs and Skin

Lafaha, kala-goysyada, muruqyada, dareemeyaasha, iyo xididdada dhiigga ee addimmada waxay aad ugu eg-yihiin kuwa qaangaarka.

Usbuuca 8da epidermis, ama maqaarka sare, wuxu noqonayaa xuub lakbyo badan, oo lumiya khafiifnimadiisa layska arkayo badankeeda.

Sunniyadu waxay soo baxaan islamarka ay timo ka soo muuqanayaan afka wareeggiisa.

Chapter 36   Summary of the First 8 Weeks

Siddeeda usbuuca ah wuxu calaamad u tahay dhammaadka xilligii embriyaha.

Waqtigaan gudihiisa, embriyaha benii aadamku wuxu koray min hal unug illaa ku dhawaad 1 bilyan unugyo oo sameeya 4,000 qaab dhisme-jireed kala duwan.

Embriyuhu wuxu haatan leeyahay ka badan 90% qaabab laga helo qaangaarka.
