Inqindi yesetyhi yesetyhini

Isalathisi sokuzala, esibizwa ngokuba yiqanda, siyilo elincinci elincinci, apho i-uniforms distribution of incellations inclusions iphawulwe. Ngaphandle, iseli lesithwathwa sowesetyana, ibhola elifanayo, lihlanganiswe ngegobolondo elimnyama kwaye lijikelezwe ngqongqelo lweeseli ezilandelwayo ezenza umsebenzi wesondlo. Ukongeza koko, badlala indima yoluhlobo lwesithintelo, ngoko bahlala besenza umsebenzi wokuzikhusela.

Ziziphi iimpawu zenkqubo yokwakhiwa kweeseli zesini zesini?

Iqanda, elingaphantsi komjikelezo, libizwa ngokuba yi-oocyte. Zonke iiseli zesini zahlula ngo-meiosis. Kufuneka kuqatshelwe ukuba kwinqanaba lesahlulo kwiiseli zesini kukho ezinye iinkalo. Ngoko ngokukodwa kwinqanaba lokuqala lokwahlukana iqanda lilibazisekile ekuphuhliseni, ngelixa likhula ngokukhulu.

Kuyabasetyhini, kwinqanaba lokuphuhliswa kwe-intrauterine, ukusuka kwi-oogonia - zeseli zesini eziphambili, ii-oocytes eziliqela. Kubalulekile ukuba uqaphele ukuba ixesha elithile ngaphambi kokuzalwa kwamantombazana ama-oocyte aguqulwa abe yintollicle, i. ezizungezile zenziwa igobolondo, ekhankanywe ngasentla.

Zonke iifolli eziphuhlisayo ziyaqhubeka zikhula kwaye ekugqibeleni ziyoncipha okanye zikhulule ii-oocytes eziphakathi kwazo. Kufuneka kuqatshelwe ukuba kumntu ovuthwa ngayo i-oocyte kwenzeka kuphela ekuqaleni kokutshatyalaliswa. Ngaloo ndlela, kunokuthiwa iiseli zokuzalana zentombi zivuthiwe kwii-ovari, okanye kunokuba zilandele iifollicle.

Ziziphi iimpawu zenkqubo yokuhluthwa kweeseli zesini zesini?

Ngethuba lokuvuthwa, i-oocyte eyinhloko iphantsi kwesahlulo se-meiosis, esiphumela ekubunjweni kwe-oocyte yesibini, eyona idlule ngaphezu kweyokuqala. Kule meko, le selinye ine-haploid, i.e. isiqingatha sezinto ze-chromosomal, kunye ne-yolk ngaphezulu kune-oocyte eyona nto.

Emva kokuba ukuvuthwa kweeseli zesini zesini sele kugqityiwe, i-vial, ehambelana ngqo ne-epithelium ye-gland ngokwayo, i-ovary, iphukile. Emva koko, i-oocyte yesibili ishiya ngqo ngaphakathi kwisisu esiswini (inqubo ye-ovulatory), apho ithathwa yi-cilia efumaneka kwiibhulo zomzimba, ingena kwi-tube fallopian.

Ziziphi izinto eziphambili zeeseli zesini zesini?

Xa sele sisebenzisana negama lesini sesini, sele sihlolisise isakhiwo sayo, kubalulekile ukuthetha ngokubaluleka kwayo. Ngoko, phakathi komsebenzi wamaqanda, kuyimfuneko ukubizwa igama:

• ukuzala - umntwana uvela kwiqanda elikhulelweyo;
• ukugcinwa nokudluliselwa kolwazi lwezofuzo.
