Pafupifupi, voliyumu ya ubongo wamwamuna ndi yayikulu 8-13% ndi magalamu 150 kulemera kuposa mkazi. Kuphatikiza apo, mwa amuna, hippocampus ndi wamkulu - gawo laubongo lomwe limayang'anira kukumbukira ndikuwonetsetsa.

Komabe, ndi voliyumu yaying'ono yaubongo, azimayi amagwiritsa ntchito bwino kwambiri chifukwa cha kulumikizana kopitilira pakati pa ma neuron. Chifukwa chake, mkazi amakhala ndi mgwirizano wamphamvu pakati pa ma hemispheres, omwe amamulola kuchita zinthu zingapo nthawi imodzi. Chifukwa chake, kuyankhula ndikuyendetsa galimoto ndichinthu chachilendo kwa mkazi. Koma kwa bambo, ayi - amatha kuyang'ana pa chinthu chimodzi.

Ngakhale abambo ndi amayi amagona mosiyanasiyana: mwa amuna, ntchito zamagetsi m'maloto zitha kugweratu ndi 70% (iye ndi mlenje, ndipo akafika kunyumba, ayenera kupuma bwino), ndipo mwa akazi - pokhapokha 10%, chifukwa nthawi zonse amayang'anira »Kunyumba ndi ana.

Ndipo zikomo zonse chifukwa cha kuchuluka kwa testosterone, komwe kumakhudza ntchito ya ma toni - gawo laubongo lomwe limayendetsa mtima. Izi zimagwira makamaka kwa amuna azaka za 17 mpaka 28, pomwe kuchuluka kwa testosterone m'magazi kumafika pazambiri. Kuphatikiza apo, kafukufuku waposachedwa awonetsa kuti kuchuluka kwa testosterone kumakhudzanso umunthu ndi machitidwe - mwachitsanzo, anthu omwe ali ndi kuchuluka kwa mahomoni awa amakhala ochezeka, opanda chidwi komanso odzidalira. Amakonda kutchuka komanso kudzilankhulitsa kuposa anzawo omwe ali ndi gawo lotsika la mahomoni awa.

Komabe, makinawo amagwira ntchito komanso mosemphanitsa. Asayansi ochokera ku Yunivesite ya Nypissing, Canada apeza kuti zochita zankhanza zimachulukitsa kuchuluka kwa testosterone m'mwazi.

Zodabwitsa ndizakuti, mahomoni omwe amapangitsa amuna kukhala olimba mtima amatsogolera kudula, pomwe akufulumizitsa kukula kwa tsitsi kumapuma thupi lonse - chifuwa, zikondwerero, kumbuyo. Molondola, chifukwa chachikulu sichinthucho chimakhala chokha, koma kusinthika kwawo kukhala dihydrotestosterone. Zotsirizirazi zimapangidwa mu Prostate, gland wa adrenal ndi scalp. Kuchepa kwake kumachepetsa tsitsi, lomwe limatha kufa kapena kuzimiririka ndi kukula kwamwana. Kupsinjika kukuthandizira kufulumizitsa njirayi, chifukwa imayambitsa kupanga adrenaline - banja lomwelo la testosterone.

Chiwopsezo cha amuna

Chosadabwitsa kuti, thupi laimuna limathanso kupanga mkaka. Prolactin ya mahomoni, yomwe imasungidwa kwambiri nthawi yapakati ndi amayi, imadziwika kuti ndiyo yoyamwitsa. Komanso sizachilendo kwa thupi laimuna, koma nthawi zambiri sizimafika pamlingo wofunikira kuti maonekedwe amkaka akhale mkaka. Koma malinga ndi kafukufuku yemwe katswiri wothandizira wa masewera olimbitsa thupi a Jade Diamond, adasindikiza mu 1995 m'magazini ya Discovery, kuchuluka kwa prolactin kumatha kuwonjezeka ndi kusokonekera kwa mahomoni, kufa ndi njala, kapena kukondoweza kosalekeza kwa nipple. M'mawu akuti, thupi laimuna limasinthidwanso kukhathamira, kuwonjezera apo, pali milandu yambiri ya abambo. Mu 1896, m'bukhu la The Anomalies and Curiosities of Medicine, George Gould ndi Walter Pyle adatchulapo zochitika zingapo zodyetsa mwana ndi amuna ochokera kwa nzika zaku South America. Mu 2002, Francepress adasindikiza lipoti la mayi wazaka 38 wa ku Sri Lanka, yemwe adalera ana ake awiri ali wakhanda mkazi wake atamwalira pobereka.

Magazi

Chimodzi mwazinthu zomwe zimapangitsa abambo kukhala osagwirizana ndi kupsinjika kwa thupi ndizovuta zakechitika pakubwera kwa magazi. Kuchuluka kwa magazi mwa amuna ndi, pafupifupi, malita 5-6, pomwe mwa akazi ndi malita 4-4,5 okha. Magazi amphongo amalemera kwambiri mu hemoglobin ndi maselo ofiira a m'magazi, omwe amasintha kayendedwe ka okosijeni. Chifukwa chake, kusamutsa kwa lita imodzi ya oksijeni kwa mkazi kumafuna pafupifupi malita 7 a magazi, bambo 6.

Chitetezo chofooka

Popeza ndiye "ogonana mwamphamvu", abambo amatenga matenda opatsirana kuposa azimayi. Ndipo ine ndinamutsutsa iye pa testosterone yemweyo yomwe chilengedwe chimapatsa mphamvu yoletsa kutupa. Testosterone imathandizira ntchito zamtundu zomwe zimachepetsa kutupa, zomwe zimapangitsa kuti thupi lipange ma antibodies ochepa. Zotsatira zake, abambo samangokhala ndi chitetezo chofooka, komanso amalolera katemera kukhala woipa kwambiri. Izi zidanenedwa mu kafukufuku wake ndi Dr. Mark Davidson wa Stanford University School of Medicine. Poyerekeza kusanthula kwa azimayi 53 ndi amuna 34 asanafike komanso pambuyo pa chimfine, asayansi anapeza kuti azimayi amapanga ma antibodies ambiri poyankha katemerayu kuposa amuna, ndipo panali mapuloteni otupa kwambiri m'magazi awo asanafike katemera.

Kukana kukalamba

Kafukufuku waposachedwa awonetsa kuti abambo amakula pang'onopang'ono kuposa azimayi. Chaka chilichonse amataya collagen ochepera kuposa kugonana koyenera, makamaka atasiya kusamba. Khungu lawo limakhala losalala ndipo limalimbana ndi makwinya. Koma popeza sichizolowezi kuti amuna azilabadira khungu, zomwe zimadwalanso nthawi zonse chifukwa kudula, zotsatira za izi sizikuwoneka.

Masomphenya adziko lapansi

Pafupifupi mamiliyoni asanu ndi awiri, omwe ali ndi vuto lautoto, ali pamaso a munthu. Ma chromosome a X ndi omwe amawachititsa kuchitapo kanthu. Amayi ali ndi ziwiri za izo, ndipo phale la mitundu lomwe amawona ndilofalikira. Chifukwa chake, pokambirana iwo amakhala ndi mithunzi: "aquamarine", "mchenga", "khofi wopepuka". Amuna amalankhula za mitundu yofunika: ofiira, oyera, amtambo.

Akazi apanga mawonekedwe owonekera. Mwa zina mwa izo, zimafika pa 180º, ndichifukwa chake azimayi samayendetsa galimoto mosavutikira poyendetsa galimoto ndipo amatha kuyang'ana mwana osatembenuza mitu yawo. Ubongo wa mwamunayo umawonetsera masanjidwe, iye "amatsogolera" chandamale, amawona zomwe zili patsogolo pake, osasokonezedwa ndi zinyengo. Asayansi akukhulupirira kuti izi ndi chifukwa cha chisinthiko - bambo yemwe amasaka mlengalenga, ndipo mzimayi amatenga nawo mbali, zomwe zikufunika kusiyanitsa zazing'ono.

1. Tsitsi la thupi limayamba kukula m'mimba

10. Kukopa zogonana kumabwera kuchokera ku tsitsi la thupi

Ndi tsitsi pa thupi, osati pamutu, lomwe limagwira ntchito ngati njira yokopa anyamata kapena atsikana. Chifukwa chake tsitsi ndi tsitsi la kumbuyo zimagwira ndikuthandizira kuti ziume ma mahomoni apadera omwe amatulutsidwa ndi matupi athu, kotero kuti amawuluka mlengalenga ndikufikira pakumva fungo la anyamata kapena akazi.

Tsitsi laumunthu wamwamuna m'dera lumbar ndi mapewa: mfundo zazing'ono 10 zosadziwika

Oimira abambo achimuna amakhala ndi tsitsi lowonda - mumkhalidwe wofananawo, tsitsi lochuluka limapangidwa pa thupi la mwamuna. Oyimira ena ogonana mwamphamvu amakhala ndi tsitsi lambiri lamthupi ndipo amanyadira nalo. Achinyamata ena, mmalo mwake, amachepetsa kutsuka kwa thupi - nthawi zambiri, nthawi yotentha. Malinga ndi ziwerengero, achinyamata omwe ali ndi zaka 16 mpaka 24 ndi omatira a tsitsi kumachotsa thupi: 58% ya achinyamata ameta tsitsi lawo lonse. Amuna omwe ali ndi zaka 50-65, m'malo mwake, amanyadira tsitsi lawo - 22% yokha, malinga ndi kafukufuku, amachotsa tsitsi lonse.

Tsitsi la thupi limagwira ntchito yoteteza khungu

Nthawi zambiri, anyamata amakono amafuna kukhala ndi khungu losalala, mosiyana ndi abambo awo ndi agogo awo. Malinga ndi kafukufuku, 60% ya anyamata achichepere amamva kufunika kometa tsitsi lonse matupi awo.

Kuphatikiza apo, pazophimba za magazini onyezimira, amuna ambiri amakhala ndi chifuwa chosalala. Nkhaniyi ikufotokozera zazidziwitso zazing'ono zokhudzana ndi tsitsi laimphongo, komanso kuyankha funso la momwe mungachotsere tsitsi kumbuyo.

Tsitsi pa thupi laimuna: zimayambitsa kukula kwa tsitsi m'mimba ndi zina zazing'ono zomwe sizidziwika

Sikuti anyamata onse amadziwa kuti tsitsi limayamba kukula lisanabadwe. Poyang'ana koyamba, palibe tsitsi pa mwana. Komabe, asanabadwe mwana wamwamuna amadzimenya tsitsi lake loyamba - lanugo.

Lanugos amadziwika kuti ndi tsitsi loonda lomwe limapangidwa mthupi la mwana.

Komanso pakubadwa, khanda lisanafike limakutidwa ndi tsitsi la fluff. Komabe, posachedwa tsitsi lotere limadzitengera lokha - ndipo khungu la mwana limayamba kusalala.

Mitundu itatu ya tsitsi la thupi

Lanugo amadziwika ngati mtundu woyamba wa tsitsi. Pambuyo pa kuwonekera kwa lanugo pamatanda a mwana, mawonekedwe a tsitsi la cannon. Sizimapanga tiziwalo ta sebaceous - pansi pa makhoma ndi malo ena.

Pambuyo powoneka ngati tsitsi loterolo mwa achinyamata, tsitsi la ndodo limayamba kukula. Ndizolimba kwambiri, zimakula pakhungu la pakhungu komanso pakhungu la sebaceous - pamphepete ndi malo ena. Zotsatira zake, mnyamatayo amakhala ndi fungo lamthupi.

Atsikana ambiri amakonda tsitsi lachilengedwe komanso loyera

Kodi atsikana amaganiza bwanji za ubweya wa anyamata? Kuyambira kalekale, atsikana anali ndi lingaliro losiyana ndi kutsitsi la amuna - tsitsi lamnyamata limawonedwa kuti ndilovomerezeka pagulu.

Pakadali pano, anyamatawa amafuna kuti atsikanayo azikhala ndi khungu losalala lopanda mawonekedwe - zomela zilizonse pa thupi la mkazi ndizosavomerezeka.

Nthawi yomweyo, malinga ndi zotsatira za kafukufuku wina wosiyanasiyana, atsikanawa amafuna kuti anyamatawa azisamalira matupi awo ndikuchotsa tsitsi lowonjezera - ngakhale nthawi zambiri zofuna za azimayi pankhaniyi zimakhala zochepetsetsa kuposa zachimuna.

Malinga ndi madotolo, kuchotsa tsitsi pamiyendo, mkono ndi pansi pazingwe ndi ntchito yowopsa. Amuna onse amakhala ndi tsitsi pachifuwa chawo. Momwemonso, pali malingaliro 2 achikazi:

Komanso, amuna ena amakhala ndi tsitsi kumbuyo - azimayi ambiri satsutsana nazo. Komabe, momwemonso, ngati munthu aziyang'anira thupi lake, ndiye kuti amachotsa tsitsi lowonjezera kumbuyoku.

Tsitsi la amuna limakhala ndi chitetezo chodalirika

Mwa anyamata achichepere, tsitsi la cannon lasiya kukula - m'malo mwa iwo, tsitsi la ndodo limayamba kukula. Tsitsi la ndodo limapangidwa ndi timinyewa ta sebaceous. Amaletsa mabakiteriya ndi mabakiteriya kuti asalowe pakhungu ndi tsitsi. Izi ndizophatikiza.

Komabe, mabakiteriya amawola, omwe amachititsa fungo losasangalatsa pansi pa manja ndi kwina kulikonse.

Kusintha tsitsi lakumaso ndi mafuta

Pakadali pano, olemba mbiri ena amakhulupirira kuti mawonekedwe a tsitsi pamthupi la munthu adalumikizidwa ndi kuchepa kwamafuta komanso mosemphanitsa.

Mukakhala pafupi ndi nyanja, anthu adayamba kukhala opanda tsitsi. Tsitsi locheperachepera limakula pa thupi laimuna, zinali zosavuta kuti munthu asambe ndikusodza. Mafuta ambiri amapangidwira kuchepa kwa thupi.

Chiyanjano cha kuchuluka kwa tsitsi la thupi ndi luntha laumunthu

Malinga ndi katswiri wazamisala wina waku United States, Aikarakudi Alias, tsitsi laimuna limaphatikizidwa ndi luntha laumunthu. Mu 1996, adotolo adachita kafukufuku ndipo adazindikira kuti tsitsi lomwe limakhala pachifuwa mwa amuna nthawi zambiri limakula mwa anthu otere:

Pophunzira za kutsuka kwa ophunzira, dotolo adazindikira kuti anyamata omwe ali ndi masamba obiriwira tsitsi pachifuwa kapena kumbuyo amalandila mayeso apamwamba kwambiri. Komabe, amuna omwe ali ndi khungu losalala sangataye mtima - pali anyamata anzeru pakati pa osakhala aubweya (mwachitsanzo, Albert Einstein).

Tsitsi pa thupi lili ndi minofu

Tsitsi pa thupi laimuna limakhala ndi maselo amisempha. Minofu ya tsitsi imadzipangitsa kumva ngati munthu ali ndi zotupa kapena zotupa za pakhungu.

Minofu ya tsitsi pamgwirizano wamunthu wamwamuna ndipo tsitsi limadzuka lokha pazinthu zina - makamaka, polumikizana ndi kuzizira, mawonekedwe a mantha komanso nthawi zina.

M'miyezi yotentha, kukula kwa tsitsi la thupi kumathandizira

Malinga ndi kafukufuku wa Brian Thompson, katswiri pa matenda a tsitsi kuchokera ku USA, tsitsi la thupi limakula mwachangu nyengo yotentha (masika, chilimwe) kuposa kuzizira (nthawi yophukira, chisanu).

Malinga ndi dotolo waku America, nthawi ya kasupe ndi chilimwe mu tsitsi zimapangidwira, zomwe zimatsogolera ku kukula kwawo. Komabe, kukula kolimbitsa thupi kumawonedwa kokha pakhungu ndi tsitsi la pubic.

Momwe mungachotsere tsitsi lowonjezera: kuchotsa tsitsi laser ndi njira zina zochotsera tsitsi

Mothandizidwa ndi laser, akatswiri pankhaniyi amachotsa tsitsi kwa amuna pamthupi - tsitsi kumunsi kumbuyo kwa amuna, tsitsi pamapewa a munthu ndi chifuwa.

Kuphatikiza apo, cosmetologists amachotsa tsitsi la laser m'manja mwa amuna. Kutalika kwa tsitsi la laser ndi mphindi 30, chiwerengero cha magawo ndi 8. Zotsatira za kuchotsa tsitsi la laser zimasungidwa kwanthawi yayitali.

Pambuyo popita nthawi yonse yochotsa tsitsi la laser, bambo sangapite ku salon kwa miyezi 6 - panthawiyi, tsitsi silikula konse m'malo omwe amathandizidwa ndi chipangizocho.

Kusintha kwa msana - kuchotsa tsitsi lochulukirapo

Chotupa choterocho chimakhala ndi masamba a 1.5 inchi, ndipo chimagwira. Mothandizidwa ndi lumozi, ambuye amachotsa tsitsi kumbuyo kwa munthu, mapewa ndi matako ndi tsitsi kumapazi a amuna.

Kutalika kwa njirayi ndi mphindi zosachepera 20. Komabe, patatha masiku angapo, tsitsili limakumananso pamalo amodzi.

Pali lumo wapadera wa malo ovuta kufikira thupi

Zotsatira zake, kuti muchotse tsitsi kwathunthu, ndibwino kufunsa katswiri pankhaniyi ndikuchotsa tsitsi la laser.
