Zosangalatsa zokhudzana ndi amuna

Choyamba, mfundo zokhudzana ndi majini. Zimatsimikiziridwa ndi sayansi kuti akazi ndi ovuta kwambiri kuposa amuna. Zonsezi ndi za chromosomes. Matenda a munthu amene amachokera ku X chromosome kuchokera kwa mayi ndi Y chromosome kuchokera kwa bambo. Kwa milungu isanu ndi umodzi mutatha kutenga mimba, mazira onse a munthu amayamba (mwachisawawa), ngati atsikana, potenga ma jini kuchokera ku DNA ya mayi. Pambuyo pa sabata lachisanu ndi chimodzi la chitukuko, ngati ndi mimba yamphongo, jeni ya SRY yomwe imapezeka pa Y y chromosome imayamba kutenga nawo mbali zina za androgens (makamaka zochepa za estrogens), makamaka testosterone, zomwe zimalimbikitsa chitukuko cha ziwalo zamwamuna.

Kusiyanasiyana kwa kugonana kwachilombo ndiko makamaka chifukwa cha kusiyana kwa thupi pakati pa abambo ndi amai. Malamulo achibadwa ndipo, motero, zinthu zomwe zimakhalapo kwa amuna, ziri mu Y-chromosome iyi, yomwe ilipo pafupifupi majini 200. Kumbali ina, mayi amakhala ndi malangizo oposa makumi awiri omwe amachokera ku ma X chromosomes (pali majeremusi 1,100 pa X chromosome).

Chisamaliro cha anthu nthawi zonse chimaganizira kwambiri za chikhalidwe, nzeru, kusiyana pakati pa amuna ndi akazi. Koma n'zovuta kuti apereke yankho lililonse malinga ndi zifukwa zosiyanasiyana. Ndipo umuna, monga tanenera pamwambapa, umachokera ku majini. Mwina, izi ndizo zochititsa chidwi kwambiri za amuna. Ngakhale chikhalidwe chimaimira mosiyanasiyana mmalo osiyanasiyana, pali mbali zambiri za tanthauzo lake.

Amuna (kapena mphamvu zamuna, kapena mphamvu zamphongo) ndi imodzi mwa mitundu ya chikhalidwe cha amuna. Zitha kukhala ndi zifukwa monga kudzidalira, udindo, kudzipatulira, kukwanitsa kuimirira ufulu, chikhalidwe chofanana, chikhulupiliro, ulemu.

Zoonadi, pali zinthu zovuta komanso zosadabwitsa zomwe zimadabwitsa amuna omwe amadabwa komanso nthawi zina iwo sakudziwa.

Nazi mfundo zenizeni zokhuza amuna. Mwachitsanzo, ubongo wa mwamuna wamwamuna wamkulu ndi pafupifupi 10% kuposa kukula kwa ubongo wa mkazi. Amuna amakonda kukhala wamtali, amakhala ndi minofu yambiri, ubongo wawo umakhala ndi neurons yambiri kuti mulamulire thupi. Asayansi adapeza kuti ubongo wamwamuna ndi ubongo wazimayi amagwira ntchito mosiyana. Munthu akamayesetsa kuthana ndi vuto, mbali imodzi yokha ya ubongo imakhala yogwira ntchito, koma chidwi chonse chimayambira. Azimayi amagwiritsira ntchito hemispheres, zomwe zimapangitsa iwo, motero, aluso kwambiri, omwe angathe kuthetsa mavuto angapo panthawi imodzi.

Mosakayikira, amayi ambiri amafuna kudziwa chilichonse chokhudza amuna, koma choyamba, sikoyenera kuimbidwa mlandu wa theka la umunthu chifukwa cholephera kumvetsera. Pali chitsimikizo cha sayansi pa izi. Chowonadi ndi chakuti liwu lachikazi liri ndi maulendo ambiri kuposa amuna, motero, ubongo wazimayi amangogwira ntchito zovuta kwambiri kufufuza maulendo omveka ndi kuzindikira tanthauzo lake.

Amuna omwe ali olemera kwambiri amakhala osangalala kwambiri kuposa amuna ochepa, pamene akazi amachita zosiyana.

Kutentha kwa thupi lachimuna ndikutsika pang'ono kuposa kwa thupi lachikazi.

Zosangalatsa zokhudzana ndi amuna, mwinamwake zidzawoneka zopanda pake, koma osadzudzula konse.

Mawu akuti "tikuyenera kukambirana za ubale wathu" akhoza kuopseza ngakhale munthu wamphamvu kwambiri.

Ngati munthu akunena "Ndikuitana", koma satero, sanatenge nambala ya foni, palibe chomwe chinachitika - iye anaiwala kuti achite izo chifukwa china.

Amuna ambiri amadana ndi kugula. Ndichifukwa chake dipatimenti ya zovala za amuna, monga lamulo, ili pa malo oyambirira a sitolo ya dipatimenti, pafupi ndi khomo.

Amuna ndi opusa komanso omvera kuposa akazi, koma osachepera. Amaseka kwambiri, motalika komanso mobwerezabwereza, koma akhoza kukhumudwa chifukwa chachinthu chilichonse. Ndipo iwo amakonda maphokozero, ngakhale kuposa akazi. Anyamata sangathe kusunga zinsinsi zomwe atsikana amawakhulupirira. Zoonadi, izi siziri zokhazokha zokhudzana ndi amuna, koma zimakhala zosangalatsa kwambiri.
