Uphuhliso ngamnye eziphilayo. inkqubo Iimpawu

uphuhliso ngamnye eziphilayo - iseti lweenkqubo zebhayoloji ezikhokelela ekubeni ukukhula kunye notshintsho iiseli ngexesha lonke lobukho babo. eyamkelekileyo igama lwenzululwazi - ontogeny. umsebenzi wayo ophambili kukuba iliso, nokuchonga amanyathelo eziphambili neempawu sethuba ngalinye, ukuchongwa iiphatheni, kwakunye uhlalutyo kunye ubhaqo yeenguqu ezenza ukuba kunokubangela olu tshintsho.

uphuhliso ngamnye eziphilayo hayi nje abantu kodwa zonke izidalwa eziphilayo nezityalo. Izigaba ezingundoqo zophuhliso zezi:

• Uphuhliso Predzarodyshevoe (umgca intsholongwane).
• ixesha siswini yophuhliso (uphuhliso umbungu efanelekileyo, embryogenesis).
• Kokubeleka (emva uphuhliso kokuzalwa: ukukhula, inzuzo ubunzima, ngokutsha, iyantlukwano).
• ixesha nokuguga (nokuguga).
• (Akukho bodwa ube liqonga eyahlukileyo kwi ontogeny ukufa, kodwa naluphi na uphuhliso ngamnye na isiphelo yayilusuku lwakhe) kokufa komzimba.

Cinga uphuhliso ngamnye nezityalo eziphilayo kweli nqaku encinane ngeke, yaye iya kugxininisa kuphuhliso kufutshane yabantu zehlabathi isilwanyana. Izigaba zophuhliso, njengokuba sele kukhankanyiwe, umntu musa ukutshintsha kwaye ziyahambelana nezo sele ikhankanyiwe apha ngasentla.

Gametogenesis abantu iqulathe amacandelo amabini: spermatogenesis (ekukhuleni iiseli lwegciwane oyindoda - amadlozi) kunye oogenesis (ekukhuleni gametes obhinqileyo - amaqanda). Ukuchumisa kunokwenzeka kuphela phantsi imeko iiseli zesini oqolileyo kwi mpuku inkunzi nemazi. Xa kuthe ezingaqhelekanga in inokuba kuyilwa eziphilayo - chimeras, ezinye zazo kakhulu ebonakalayo.

Embryogenesis mntu - enye izigaba ezibalulekileyo. It lahlulahlulwe isanda (0 - kwiveki 1 emva kokukhulelwa), eneneni Isigaba intsholongwane (2 - 8 iiveki) kunye eqongeni ezingekazalwa okanye ukukhubazeka (9 ngeveki - ukuzalwa). Yilaa amalungu ebalulekileyo kwakheka ngeli xesha, umzimba ezikhutshiweyo, ngazo ngokwabo okanye ezinye ukungaqheleki yemfuza.

Uphuhliso ngamnye eziphilayo kwixesha kokubeleka kukuba ukuqhubela phambili uphuhliso amalungu, ukwandisa ubukhulu kunye nobunzima, ukufumana imisebenzi emitsha yengqondo, utshintsho kumsebenzi motor kunye nophuhliso yayo iintlobo ezintsha. ixesha kokubeleka - eyona nto ibalulekileyo kuphuhliso yomntu omtsha. Ubude bayo neminyaka eyi-17 (ukususela ekuzalweni ukuya elivisayo). Kwi uphuhliso ngamnye eziphilayo ngeli xesha asichaphazeli nje iimpawu ezibangelwa imfuza, kodwa izinto zengqondo kunye nezentlalo. isazela kwakhiwa, intetho, iingcinga kunye nezinye iinkqubo ze umsebenzi ngaphezulu luvo. Ekupheleni kwale xesha, abantu abatsha, iyathanda ukuba eze gametogenesis epheleleyo.

Ukuguga - isigaba lokubola, kwamanani ubuncwane zomzimba. ukuphazamiseka ayibuyiseki umva eziseleni luvo, inwebu myelin, kunciphisa umgangatho umbono nokuva, "ziguge" amalungu abalulekileyo, utshintsho ulusu, baphulukana umsebenzi yokuzala kunye inyama ngokutsha lingancipha kabukhali, njl
