Secondary futhi eyinhloko ubulili izici zamadoda nabesifazane

Kunezindlela eziningana umehluko isakhiwo nemisebenzi kwezitho zomzimba, okuyinto ukunquma isimo zonke izinto eziphilayo ukuze eyodwa noma nezinye ocansini. Primary kanye nezici ngokobulili yesibili ukusiza ukuhlukanisa abesilisa kusukela kwabanenyanga zesifazane, futhi insikazi yomhlambi wesilisa, naphezu kweqiniso lokuthi bazimisele nge izakhi zofuzo ezifanayo ukuthi kukhona ngaphansi kwethonya hormone ekhethekile kungase ukuzibonakalisa e Ngezinga elikhulu noma elincane. Hypoplasia noma izinguquko sokugembula e ezikhiqiza amaqanda ngokuvamile kakhulu buthaka umphumela le-hormone zesifazane, okuholela ukubonakaliswa izici yesibili ezingabantu. umzimba zokugcina lona lingabhalela futhi afakazele kuye ushintsho extrinsic, futhi ngokuvamile kuba khona isizathu salokhu nokucindezela ukusebenza evamile ye testes. It lingahunyushwa baphetha ukuthi izinhlamvu ngokobulili eyinhloko kufaka umzimba ukuthi unesibopho kokukhulelwa nokuthuthukiswa umbungu. Uhlelo okuzala ka umzimba ingenye ezibaluleke kakhulu, ngakho impilo yakhe kufanele kugcinwe isikhathi eside ngangokunokwenzeka.

izici ngokobulili Primary

- I umthondo, wesinye amasende ezingabantu.

- I sangasese, kwesibeletho futhi ezikhiqiza amaqanda e abesifazane.

Nokho, izimpawu Secondary yentuthuko socansi ebonwe kwabesifazane nabesilisa, ziyabonakala degrees obuhlukahlukene.

Izimpawu yesibili nokuvuthwa zocansi

izinwele umzimba ezingabantu kubonakala ubuso, esiswini, esifubeni, emikhawulweni emuva, engenhla nengezansi, kanye endaweni pubic. Ngo abesifazane, into enjalo kule ukulinganisela ebonwe emakhwapheni, endaweni bikini nasemilenzeni. Ngaphezu kwalokho, kukhona umehluko ku skeleton kanye ezicutshini: esifubeni besilisa emahlombe ebanzi, nemilenze eside, ukhalo kakade, futhi muscle and bone mass mkhulu. izicubu Ongama kuyinto esithuthuke kabanzana lapho esiswini, ngenkathi abesifazane ke itholakala emathangeni nezinqe. izintambo Vocal mkhulu izwi rougher besilisa, kanye apula akhe Adamu ngensimbi. nezindlala mammary ngokuvamile athuthukile futhi ayikwazi lokukhululwa ubisi lwebele ekunikezeni ukudla yenzalo. Uma izinhlamvu ngokobulili eyinhloko zinezikhathi isakhiwo ethile, secondary babelemisebenzi eminye umehluko kusuka abamele bobulili obufanayo.

Izici ukuthuthukisa izici ngokocansi

ukuthuthukiswa ngokocansi e kwabesilisa nabesifazane kwenzeka ngesikhathi ezahlukene: iqanda, isibonelo, kwakhiwa kudala njengoba ngesikhathi embryonic ukuthuthukiswa, kodwa eqala ukukhula kuphela kweminyaka eyi 8-12. isidoda samadoda ikhiqizwa amaqanda kwaze kwaba kamuva, ngemva kweminyaka engaba ngu-13. izici ngokobulili Primary, kanye yesibili, kwakheka ngenxa imiphumela yama-hormone athile e kwabesifazane progesterone futhi i-estrogen, ezilungiselela umzimba ukukhulelwa, futhi amadoda - testosterone.

Kunezikhathi lapho ingenye kwezinhlobo Ingase ithanyelwe, nowesifazane, indlala besilisa kanyekanye. Lesi senzakalo ngokuthi hermaphroditism futhi kwenzeka ngenxa ukuthuthukiswa okungavamile kwesimiso sokuzala. Uma izici ngokobulili eyinhloko ziyabonakala ekuseni, yesibili imiswe phakathi ukukhula umzimba. Ekugcineni, lo muntu esefinyelele ukuvuthwa yezinto eziphilayo, kuhlanganise ocansini, lapho iza ngemuva kokuphothulwa ukuthuthukiswa bokuphila morphological. Kusukela leli phuzu umzimba uyakwazi nokuzala inzalo egcwele enempilo.
