Ubume umzimba obhinqileyo: iimpawu yokwakheka kunye nokomzimba

Morfoanatomicheskoe umahluko phakathi ngokwesini ezimbini unalo igama elithile. Eziphilayo, le nto kuthiwa dimorphism ngesondo. Ngaloo ndlela yokwakheka kunye nokomzimba iiyantlukwano amadoda nabafazi ngendlela ebanzi, ngenxa umbandela yemfuza, ingakumbi, ukuba amabini X-zofuzo uhlobo ngokwesini. Olu phawu lowo wokuqala, sele kubonakala kwiqondo elilodwa. Enyanisweni, oku kuthetha ukuba kwinqanaba kwiseli enye apho umbungu okhula kamva, kusenokwenzeka ukuba agwebe umahluko ngokwesini. Noko ke, kubonakala kuphela kwinqanaba le-genetic material.

Isakhiwo yokwakheka komzimba nemazi

Indima begazi yamabhinqa kubantu - umithi nomntwana kunye osikwa yinimba. Ngokungqinelana nale nkqubo amalungu abasetyhini kakhulu apha naphaya ukuphumeza inkqubo. Kufuneka bonisa esini kubume yokwakheka. Ngenxa umahluko kubume amalungu we nokusebenza imigangatho ayifani.

Phakathi nobufazi kukho qheke kwi umphandle nomphakathi. Le organocomplexes yangaphakathi ziquka gonads, tubes, wesibeleko, lobufazi. Owokuqala yentsimbi na uhlobo olungumxube secretion, njengoko nokulungelelanisa kunye neeseli eyintsholongwane hormone okuziphatha nefuthe komzimba emzimbeni yonke yabafazi. Isibeleko, lelona candelo apho umbungu lonke ixesha. ixesha elithile emva kokukhulelwa kwi ampoule Imibhobho ityhubhu iqanda lihlala kwisisu yayo. Ukulibaziseka izakheko yokwakheka kukhokelela pregnancy, ebizwa apho isakhiwo umzimba yomfazi ayinikezi. Ngoko ke, xa ingxaki enjalo ukukhulelwa kuyacetyiswa okanye ukupheliswa okanye umbungu ukudlulisa yayo, nangona lo msebenzi ezintsonkothileyo.

Isibeleko na ilungu dystrophy, ngokubonakalayo banabileyo ngexesha yokumitha. Kuye isethi umzimba kunye entanyeni, uyila iphecana zangasese. Ngokutsho kwakhe iiseli zesini samadoda ahlasele tshintsho bokuhlala ityhubhu Imibhobho, apho iqanda.

isakhiwo umzimba A yomfazi luxhomekeke ebalulekileyo inkqubo eziphilayo, apho indalo inikeza onke amathuba ophuhliso yosana olungekazalwa, ngokunjalo lonikezelo. isakhiwo Main zomzimba, ngempumelelo Ulobumba umsele wokuzalwa lobufazi. Lo mzimba ezibuhlazarha ise isinqe, nodonga lwawo kokuthintela nokushukumisa intloko ezingekazalwa ekuzalweni.

Ubume umzimba nemazi: womntu obhinqileyo

Yi zangaphandle esini ekubhekiselwe andihlangabeze amabele, kwiLibia ezinkulu nezincinane. Ingqiqo endalo, uMenzi isakhiwo yamabhinqa inkqubo phylogenesis, nayo ilele ngethuba ekondleni usana olusanda kuzalwa kunye nemveliso amandla ophezulu, nto leyo imfihlelo lwebele - ubisi kwabantu. Inkqubo yokukhethwa kuxhomekeke utshintsho komzimba emzimbeni yabafazi. Ngexesha kwamadlala ukukhulelwa ukuphuhlisa, kwaye ukusuka kumasebe secretory baqale ukwakha imibhobho ukuba idibane mmandla kwingono. Oku kulawulwa yinkqubo hypothalamic-yebhinqa kunye prolactin hormone. Xa umfazi uvelisa umntwana ehlabathini, uqhuba inkqubo zisanyisa, okt ukwahlulwa ubisi. Kuphela ngenxa umntwana wakhe bangondliwa kangangeenyanga eziliqela, yaye ngoko ke kufuneka uqale ukusebenzisa instantons okuziinkozo ukudla kwakhe.

Ubume komzimba imazi ikwaquka umthondo abancedisayo ibekwe ngaphandle. Yinto kwiLibia. umsebenzi wabo kukukhusela kwevaranda evela kwii kwamagciwane. Kulo mzekelo, imilebe kwiLibia ezi amadlala exocrine ezikhethekileyo. Bona cell imfihlo enuka kamnandi. imfuneko lwakhe iimeko zentlalo mihla azithathelwa ngqalelo, ekubeni uphuhliso lifumene inkqubo uphawu yesibini womntu. Ngaphambili, imfihlelo ezi amadlala bakhonza uphawu ukulungela ngomlomo ukuba zizale. Kuyaphawuleka ukuba isakhiwo umzimba elithokazi kuphela esini ezahlukeneyo, yaye uneempawu zawo kumgaqo-siseko, wacinga iipateni, umlinganiswa.
