Uphuhliso lwe-Post-embryonic

Ixesha elibelwe isiphila esiphilayo sokufezekiswa kweprogram yayo yemfuza ngokuqhelekileyo kuthiwa yi-postembryonic okanye emva kokuzalwa (kumntu) ixesha lokuphuhliswa. Iqala ngethuba lokuzalwa kwaye liphela ngokufa, kwaye ixesha lixhomekeka kwiimpawu zendalo, indlela yokuphila, iimeko zangaphandle kunye nezinye izinto.

Kwabancinci abazalwana kunye nabantu, ixesha lokuphuhlisa i-postembryonic liqukethe amanyathelo amathathu:

1. I intsana. Leli nqanaba lokuqala - linqunywe lixesha ukususela ekuzalweni ukuya ekuphumeni, kuhamba kunye nokukhula okusebenzayo, ukubunjwa kokugqibela kwazo zonke izitho kunye neenkqubo, kwaye ziqhubeke ngeendlela ezahlukeneyo. Ngokukodwa, iintlobo ezimbini zokuphuhliswa kwe-postembryonic ziyahlukana: ezichanekileyo kunye ezingekho ngqo. Ukuba umntu osandul 'ukuzalwa ufana nomntu omdala kunye neempawu zangaphandle kunye neempawu zentlangano yeenkqubo zemizimba, ke oku kuphuhliso lwe-postembryonic ngqo. Kwimeko yokuphuhliswa ngqo, i-organic is subject to metamorphosis.
2. Ubusuku, okanye ixesha lokusuka. Le ngenye yezona zigaba ezide kakhulu zokuphuhlisa i-postembryonic, xa umzimba unako ukuvelisa.
3. Ukuguga. Isigaba sokugqibela sokuphila komjikelezo wobomi, ophelisa ukufa okanye ukunyanzelwa ukufa.

Iimpawu zenkxaso ye-postembryonic yophuhliso loluntu

Izitho kunye neenkqubo zendoda encinci zenziwa kwisibeleko somama, apha umntwana ufumana izinto eziphathekayo zofuzo, nto leyo eyona nto ibalulekileyo ekuphuhlisweni kwayo. Ixesha le-intrauterine linamanyathelo alo, ngalinye elo libonakaliswe ngenguqu eguqukileyo.

Ngokomzekelo, ngenyanga yesibini yokukhulelwa i-embryo iba njengomntu omdala, nangona ubukhulu bayo abugqithanga ngaphezu kwe-3 mm, kwaye ukuhlala ngaphandle komzimba kamama akunakwenzeka. Ngethuba lokuzalwa ubunzima bomntwana bufikelela kuma-3-4 kg, ubude buyi-45-55 cm, kunye neenkqubo eziqinisekisa ukuba umsebenzi obalulekileyo womzimba sele ulungele ukusebenza ngokuzimeleyo.

Xa ubona umntwana osanda kuzalwa, kuyacaca ukuba indlela yokuphuhliswa kwe-post-embryonic iya kubakho ngqo. Ekubeni umntu omdala uhluke kumntu omdala kuphela ngokobukhulu bomzimba kunye nokungahlanjululwa kwezinye iinkqubo.

Isikhathi sokubeleka sokuphuhliswa komntu, njengento yokuqonda, sele sifunde ngokufanelekileyo, kwaye ihlulwe ngo:

1. Ixesha elisandul 'ukuzalwa lintsuku elishumi emva kokuzalwa. Ngelo xesha, umntwana usechitha ixesha elininzi ephupheni, kwaye ukukhula okupheleleyo nophuhliso ufuna ubisi lwebele.
2. Ixesha lesifuba - ukusuka kwiintsuku ezili-10 ukuya kunyaka. Ngelo xesha, i-crumb yenza inqabana enkulu ekuphuhliseni kwengqondo nokuziphathekayo. Ekupheleni konyaka wokuqala wobomi, ininzi yabantwana sele isele imile ngeenyawo zabo, idla ukutya okuhlukahlukeneyo, iibllabha zokuqala zithetha.
3. Ubuntwana beminyaka yokuqala engama-1-3. Kubantwana, ukulungelelaniswa kwezinto zihamba kakuhle, banako ukucacisa ngokucacileyo nangokuqhubekayo iingcamango neemfuno, bazalise rhoqo isigama, banomdla kwihlabathi elijikelezile.
4. Ubuntwana bokuqala buyiminyaka engama-4-7. "I-Radio Kryuchochki" isasaza ngekhefu - umntwana akayi kuphumla ade athathe impendulo kumbuzo oceliwe, kwaye okokugqibela kuvela kakhulu.
5. Umntwana wesibini uneminyaka eyi-8-12. Abantwana kule minyaka bafanela ukuguqula umfanekiso wehlabathi, kubakho ukusekwa kokugqibela kwemisebenzi yomqhubi.
6. Ixesha leshumi elivisayo liyiminyaka eyi-13-16. Ama-hormone esini aqala ukuveliswa, ngokubhekiselele kuwo, kukho utshintsho olubalulekileyo emzimbeni womntwana, kokubili ngokomzimba nangokwengqondo kwengqondo.
7. Ulutsha luyiminyaka eyi-17-21. Imeko yomzimba omncinci uphelele ngokufanayo nomntu omdala.
8. Ixesha elivuthiweyo liyiminyaka engama-22-60. Kulo nyaka, zonke iinkqubo zenziwa, ukukhula kwekhasi, kwaye umntu ekugqibeleni ungene kwisigaba sokuzala.
9. Ubudala buyiminyaka engama-61-74. Iimpawu ezinobungakanani beempawu zangaphandle ezibonisa ukutshiswa komzimba.
10. Ixesha elidlulileyo liyiminyaka engama-75 ukuya kwe-90.
11. Ixesha elide- ngaphezu kweminyaka engama-90.
