Kuyini isidoda? Izici Ezihilelekile Kule gamete besilisa

Medicine amumethe ezihlukahlukene imigomo. Ezinye zazo yilezi elula liqondwe abantu abavamile. Ezinye zidinga ukuchazwa. Lesi sihloko uzokutshela ukuthi isidoda enjalo. Uzofunda mayelana izici isakhiwo esitokisini. Wena uzokwazi ukuthola isidoda eziningi kanjani bukhoma ngaphandle isidumbu somuntu. It kufanele licaciswe futhi imisebenzi eyisisekelo gametes.

Kuyini isidoda?

Lokhu cell likhona emzimbeni besilisa zinhlobo ezahlukene. Nokho, njalo kunazo wafunda e gamete womuntu. Uma unombuzo, yini isidoda ke lesi sihloko uzokutshela ngakho.

Isidoda - iseli zokuzala, ngaphandle okuyinto akunakwenzeka ukuzala. Kumiswa It is in the testes of DUNA ezikhishwe phakathi ejaculation. On isidoda ukukhiqizwa kuthintwa izinto eziningi. Ngakho-ke kuwumsebenzi kohlelo kwama-hormone ngesikhathi indoda, indlela yakhe yokuphila, ngokomzwelo futhi isimo somzimba. Isakhiwo gametes ithakazelisa kakhulu. Kuyini isidoda? Lokhu cell, okuyinto has a ikhanda umzimba omkhulu futhi umsila. Gametes ifa isivinini kahle eliphezulu. It ivumela ukukhiqiza kokukhulelwa. Lawo mangqamuzana angaba ngu okuyinto ungenayo ingxenye, noma ukuhamba ngendlela efanele, ovame ukubizwa ngokuthi isidoda. Kuthiwa ukuthi isidoda inquma ubulili wengane ongakazalwa. Leli qiniso kuncike okuqukethwe wama-chromosomes ezithile ku gametes. Le kit lingaba nalokhu X noma Y-chromosome. Ngakho, aba khona uma uphonsa ebamba isisu is umbungu ukuthi ungowesifazane noma owesilisa.

iseli isakhiwo

Njengoba usuvele uyazi, spermatozoon ziyahlangana siqukethe ikhanda, umzimba kanye nomsila. Lezi zingxenye, esikhundleni salokho, kufanele izici zabo. Ake sihlole kubo.

• Shona. Le ngxenye equkethe umongo kokuba ezithile zofuzo. Kubalulekile kakhulu ukuze sithele. Ngaphezu kwalokho, kukhona acrosome. Le into akusho iqhaza ekwakhekeni zygote. Nokho, ikuvumela ukuncibilikisa igobolondo amaqanda bese uthole ngaphakathi. Centrosome - lena umniningwane obalulekile evumela ukuhamba ngendlela efanele umsila.
• Umzimba. Azikho izingxenye kubalulekile insemination yokufakelwa. Nokho, emzimbeni isidoda iyona cytoskeleton. Le ngxenye kusiza cell ukuba abashukumise futhi bafinyelele umgomo wabo.
• Ponytail. Le ngxenye ongaqhubeki-chromosome. Kodwa kuwufanele ethi ngaphandle gamete wakhe wesilisa nje awukwazi ukususa. umsila ngoMthetho centrosome, esemgwaqweni ekhanda cell. Kukhona esinye isici. Uma amangqamuzana besilisa abanalo imisila, lo sokukhulelwa singenzeka ngokusebenzisa tube.

Isakhiwo efanele isidoda kubaluleke kakhulu ukuze sithele. Yingakho odokotela ukukhokhela ukunakekelwa okukhethekile ukuze leli phuzu.

imisebenzi esemqoka

Kuyini isidoda, usuwazi. Ukuze okudingayo kule seli kancane emzimbeni wesilisa? Isici esiyinhloko we gametes ukuthi kungaba mnandi kanjani ngaphandle komzimba umninikhaya sika. Ngesikhathi esifanayo endaweni bangisekela imvelo isidoda ukuphila ngokuvumelana izinsuku eziyishumi.

Umsebenzi oyinhloko we-gamete wesilisa avundiswa. Kungaba khona ngokwemvelo noma okwenziwe. Amaseli ufake umzimba wobulili bubuhle, unqobe umsele wesibeletho. Kufanele kuqashelwe ukuthi kuseli eyodwa ngesikhathi esisodwa ngeke kwanele. Naphezu kweqiniso lokuthi ngesikhathi sokuhlala kwesisu iyahlanganiswa isidoda olulodwa neqanda, ngoba ukuhamba gametes wesilisa kumele kube amaningi anjalo.

Ngemva sokunqoba zesifazane izitho zangasese isidoda ingena iqanda. Kube sekuqala division okuqhubekayo. I zygote ehamba amashubhu fallopian kanye esibelethweni. Sekuvele kukhona izidakamizwa kwakhiwa okuthiwa Iqanda fetus.

izinkinga ezingase zibe khona

isidoda Male akusho ngaso sonke isikhathi isakhiwo efanele. Ngokuvamile nabobulili namandla ube ukubhekana nezinkinga. Kutholwe zokugula ukuhlaziywa ngemva ngokuthi spermogram.

Ngokwesibonelo, amanye amaseli kungase kudingeke isakhiwo noma womgwaqo ukwephulwa okungalungile. Ngezinye izikhathi kukhona umonakalo ngokwengxenye wenziwe yinhloko noma umsila we isidoda. Kwezokwelapha, kukhona nezindinganiso ezithile okufanele zifinyelelwe gametes besilisa. Ngezinye isiphithiphithi uphazamise nezimoto pathologies labetibambile ukulungiswa. Ukwelashwa Ungakwazi ukubuyisela impilo isidoda nokuthuthukisa owesilisa umsebenzi zokuzala.

Efingqa

Manje sibona ukuthi isidoda enjalo. Lokhu cell luncane emzimbeni lomuntu, kodwa wenza umsebenzi obaluleke kakhulu. Gamete futhi has izici zayo siqu ngabanye. Lokho isidoda evumela ukuba umuntu aqhubeke nemindeni yabo futhi ezala inzalo. Kufanele kuqashelwe ukuthi isakhiwo kanye nemisebenzi amaseli kufundvwe ngisho yezifundo zezikole. Wonke umuntu, ikakhulukazi indoda, kufanele wazi ukuthi lokhu isidoda. Hlola izinga ngokuhlangana kwamaseli abo enzalo. Ngikufisela inhlahla!
