Ngokwesilinganiso, ivolumu yengqondo yendoda ikhulu ngo-8-13% namagremu ayi-150 asindayo kunowesifazane. Ngaphezu kwalokho, emadodeni, i-hippocampus inkulu - ingxenye yobuchopho ebhekele inkumbulo nokunakwa.
Kodwa-ke, ngevolumu encane yobuchopho, abesifazane bayisebenzisa kahle kakhulu ngenxa yokuxhumana okwengeziwe okuthuthukile phakathi kwama-neurons. Ngakho-ke, owesifazane unokuxhumana okuqinile phakathi kwama-hemispheres, okumvumela ukuba enze izinto eziningana ngasikhathi sinye. Ngakho-ke, ukukhuluma nokushayela imoto kuyinto evamile kowesifazane. Kepha kumuntu, cha - angagxila entweni eyodwa kuphela.
Ngisho nabesilisa nabesifazane balale ngezindlela ezihlukile: emadodeni, umsebenzi kagesi wobuchopho ephusheni uzokwehla ngo-70% (ungumzingeli, futhi lapho efika ekhaya, kufanele aphumule kahle), futhi nakwabesifazane - kuphela ngo-10%, ngoba uhlala egada »Ikhaya nezingane.
Futhi konke ukubonga ezingeni eliphakeme le-testosterone, okuthinta umsebenzi wamathoni - ingxenye yobuchopho obhekene nemizwelo. Lokhu kusebenza ikakhulukazi kwabesilisa abaneminyaka engu-17 kuya kwengama-28, lapho ukugcwala kwe-testosterone esegazini kufinyelela ezingeni eliphakeme. Ngaphezu kwalokho, ucwaningo lwakamuva luye lwabonisa ukuthi amazinga e-testosterone athinta izici zomuntu siqu nokuziphatha - ngokwesibonelo, abantu abanezinga eliphakeme laleli hormone banokuhlalisana okuhle, abangenasimilo nokuzethemba. Zithambekele kakhulu ekubuseni nasekuzibonakaliseni kunontanga bazo abanezinga eliphansi laleli-hormone.
Noma kunjalo, lo mshini uyasebenza futhi okuphambene nalokho. Ososayensi abavela eNyuvesi yaseNypissing, eCanada bathole ukuthi izenzo ezinolaka zenyusa izinga le-testosterone egazini.
Kuyamangaza ukuthi i-hormone elenza amadoda abe nesibindi iholele ekugqungeni, kuyilapho esheshisa ukukhula kwezinwele kulo lonke umzimba - isifuba, izindwani, emuva. Ngokuqondile, isizathu esiyinhloko akuyona i-hormone ngokwayo, kodwa ukuguqulwa kwayo kube yi-dihydrotestosterone. Kamuva kukhiqizwa indlala yesibindi, i-adrenal glands kanye nesikhumba. Ukweqisa kwayo kwenza buthaka izinhlobo zezinwele, ezingase zife noma zinciphe ngosayizi obonwa ezinganeni ezisanda kuzalwa. Ukucindezela kuzosiza ukusheshisa inqubo, ngoba kusebenze ukukhiqizwa kwe-adrenaline - umndeni ofanayo we-testosterone.
Isibeletho sowesilisa
Ngokudabukisayo, umzimba wesilisa uyakwazi nokukhiqiza ubisi. I-hormone prolactin, efihlwa ngokweqile ngesikhathi sokukhulelwa ngabesifazane, yaziwa ukuthi inecala lokuncelisa ibele. Akuyona futhi isihambi emzimbeni wesilisa, kepha imvamisa ayifiki ezingeni elidingekayo ekubonakala kobisi. Kodwa ngokuya ocwaningweni okwenziwe yisazi sokuzivocavoca umzimba uJade Diamond, eshicilelwe ngonyaka ka-1995 kumagazini i-Discovery, amazinga we-prolactin angakhushulwa ukuphazamiseka kwe-hormonal, ukubulawa yindlala, noma ukukhuthaza okungapheli kwengono. Ngamagama nje, umzimba wesilisa nawo uhunyushwa u-lactation, ngaphezu kwalokho, maningi amacala okudla kwabesilisa. Ngo-1896, kuyi-The Anomalies and Curiosities of Medicine, uGeorge Gould noWalter Pyle bakhuluma ngamacala amaningana okuzibonela okondla ingane ngamadoda avela emadolobheni aseNingizimu Melika. Ngo-2002, abakwaFrancepress bashicilela umbiko ngowesifazane waseSri Lanka oneminyaka engama-38, owayondla izingane zakhe ezimbili ebuntwaneni ngemuva kokushona kukankosikazi wakhe ebeletha.
Ukujikeleza kwegazi
Enye yezizathu ezenza abesilisa bamelane kakhulu nokuxineka ngokomzimba yizingxaki zokuhamba kwegazi. Umthamo wegazi kwabesilisa, ngokwesilinganiso, unamalitha angama-5-6, kuyilapho kwabesifazane kuphela unamalitha angama-4-4,5. Igazi labesilisa licebile kakhulu ku-hemoglobin nasemangqamuzaneni abomvu egazi, athuthukisa ukuhamba kwe-oxygen. Ngakho-ke, ukudluliselwa kwelitha elilodwa le-oksijini kowesifazane kudinga amalitha ayi-7 egazi, indoda eyi-6.
Ukuzivikela kokuzivikela
Ukuba “ngocansi oluqine kakhulu”, amadoda atheleka kakhulu ezifweni ezithathelwanayo kunabesifazane. Futhi ngimsola ku-testosterone efanayo leyo mvelo eyabeka ngayo ngokulwa nokuvuvukala. I-testosterone ithuthukisa umsebenzi wezakhi zofuzo ezinciphisa ukuvuvukala, okwenza umzimba ukhiqize ama-antibodies ambalwa. Ngenxa yalokhu, amadoda awagcini ngokuba nokuvikelwa okungatheni amandla, kepha futhi abekezelela nokugoma okukubi kakhulu. Lokhu kuvezwe esifundweni sakhe uDkt. Mark Davidson weStanford University School of Medicine. Ngokuqhathanisa ukuhlaziya kwabesifazane abangama-53 nabesilisa abangama-34 ngaphambi nangemva kokuqothulwa komkhuhlane, usosayensi uthole ukuthi abesifazane bakhiqiza ama-antibodies amaningi kakhulu ekuphenduleni umjovo kunowesilisa, futhi kunamaprotheni amaningi okuvuvukala egazini labo ngaphambi kokugonywa.
Ukumelana nokuguga
Ucwaningo lwakamuva luveze ukuthi amadoda akhula kancane kancane kunabesifazane. Unyaka nonyaka alahlekelwa yi-collagen engaphansi kunobulili obuhle, ikakhulukazi ngemuva kokuya esikhathini. Isikhumba sabo sigcina ukuqina futhi simelana nemibimbi kakhulu. Kodwa njengoba akuyona inkambiso endaweni yabesilisa ukunaka kakhulu esikhunjeni, futhi esihlala sihlushwa ukusikeka ngenxa yokushefa, imiphumela yalesi sici cishe ayibonakali.
Umbono womhlaba
Cishe izigidi eziyisikhombisa zama-cone receptors, abhekele ukubonwa kombala, zitholakala kwi-retina yeso lomuntu. I-chromosome engu-X inesibopho sesenzo sabo. Abesifazane banemibili yabo, kanti iphalethi lemibala abalibonayo libanzi. Ngakho-ke, engxoxweni basebenza ngama-shades: "aquamarine", "sand", "coffee light". Amadoda akhuluma ngemibala eyisisekelo: obomvu, omhlophe, oluhlaza okwesibhakabhaka.
Abesifazane bathuthukise umbono ophelele. Kwezinye zazo, ifinyelela ku-180º, yingakho abesifazane bengavami ukushayela imithelela eseceleni lapho beshayela imoto futhi bebuka ingane ngaphandle kokuguqula amakhanda. Ubuchopho bendoda buhlinzeka ngombono womhubhe, "uhola" ilitshe, ibona kuphela okuphambi kwakhe, futhi kayiphazanyiswa iziphikiso. Ososayensi bakholelwa ukuthi lo ngumphumela wokuziphendukela kwemvelo - owesilisa ekuzingeleni wazingela ilitshe, nowesifazane ohlanganyela ekubuthaneni, lapho kudingekile khona ukuhlukanisa imininingwane emincane.
1. Izinwele zomzimba ziqala ukukhula esibelethweni
Into yokuqala amadoda okufanele ayazi ngezinwele zomzimba ukuthi aqala ukukhula ngisho nangaphambi kokuzalwa. Kuyiqiniso, kunzima impela ukucabanga indoda enhle enoboya esibelethweni, kepha ngesikhathi umntwana ezalwa, ulahlekelwa ezinye zezinwele zakhe zokuqala zomzimba, ezibizwa ngokuthi yi-lanugo. Lezi zinwele ezincane nezincane kakhulu zimboza cishe wonke umzimba wengane. Kwezinye izingane ezizalwa ngaphambi kwesikhathi, ungabona ukuthi i-fluff isimboza kanjani umzimba wayo wonke, kepha ungakhathazeki, ngoba ekugcineni iyanyamalala.
2. Kunezinhlobo ezintathu ezihlukene zezinwele zomzimba
ILanugo luhlobo lokuqala lwezinwele oluvelayo, ngemuva kwalo kukhona izinwele ezithambile, ezinciphile, ezingenamibala ezibizwa ngokuthi izinwele ezifudumele. Izinwele zeCannon azinamathiswanga nezicubu ezi-subcutaneous noma i-sebaceous gland. Zihluke ngokuphelele kolunye uhlobo lwezinwele - izinwele eziyisisekelo, ezibonakala ngesikhathi sokukhula kobusha. Zithinta kakhulu, zinamathele ezicutshini ezingaphansi kanye nezindlala ze-sebaceous, okunomthelela ekubonakala kwephunga lomzimba.
3. Abesifazane abaningi bakhetha ngokwemvelo kodwa ngobumnene
Ngabe abesifazane bacabangani ngezinwele ezisemzimbeni wesilisa? Ngezikhathi ezahlukahlukene, abesifazane babephatha izinwele zobuntu ngamadoda ngokwehlukile, kodwa lokhu kwakuhlala kubhekwa njengokumukeleka emphakathini.
Ngokwesiko laseNtshonalanga, abesifazane uqobo kulindeleke ukuthi babe bushelelezi ngokungenaphutha uma kufikwa kunoma iyiphi imifino emzimbeni. Kodwa-ke, ucwaningo lwabesifazane luveze ukuthi abaningi ngeke banake ukuthi amadoda nawo azibeka ethubeni, yize ezimweni eziningi izidingo zawo zinesizotha kakhulu. Singasho ukuthi ukushefa izinwele emilenzeni, ezingalweni nasempangeni kuyingozi kakhulu. Ngokuphathelene nezinwele esifubeni, abesifazane bahlukaniswe ngamakamu amabili ahlukene: kwabanye baphenduka kakhulu, kanti abanye bathanda amabele abushelelezi. Ngokuqondene nezinwele ezingemuva, yize abesifazane bekulungele ukubekezelela, abanangqondo yokubona okungenani imizamo yokuqinisa izinwele ngokweqile.
4. Unwele ngalunye luvikelwe yizinsini ezincane kunazo zonke
Njengoba kushiwo, ekuqaleni kobusha, amadoda alahlekelwa iningi lezinwele zawo ze-canon, futhi esikhundleni sawo anezinduku zezinwele. Lezi zinwele ezigqinsiwe zivikelwe yi-sebaceous gland noma izindlala ezikhiqiza i-sebum. Kuvikela isikhumba nezinwele zezinwele kusuka kumagciwane. Lolu uhlangothi oluhle. Kodwa-ke, amagciwane abola, obangela iphunga lomzimba.
5. Sishintshana ngezinwele zomzimba sibe ngamafutha
Kunomqondo ohehayo othinta ubudlelwano phakathi kwezinwele zomzimba namafutha omzimba. Abantu baqala ukulahlekelwa boya babo njengoba beqhakambisa nokuhlala eduze nolwandle. Izinwele ezincane zazisemzimbeni womuntu, kwakulula kuye ukubhukuda nokudoba, futhi inqwaba yezicubu ze-adipose isize ekunciphiseni ukulahleka kokushisa okuvikelayo.
6. Izinwele zomzimba zidlala izindima ezimbili eziyinhloko
Esikhathini esiningi, abantu bavele ngendlela yokuthi abadingi izinwele zomzimba ukuze baphile, kepha basenemisebenzi eminingana eyisisekelo. Esikhathini sezulu esibandayo, izinwele ezisemzimbeni zisiza ukugcina ukushisa, futhi ngezikhathi ezishisayo, njengoba sifunga, izinwele ezisemzimbeni zisiza ukuthola umswakama osuka esikhunjeni, zisipholise.
7. Inani lezinwele zomzimba elihlotshaniswa nobuhlakani
Ngokusho kwesinye isazi sokusebenza kwengqondo saseMelika, izinwele eziningi ozinazo emzimbeni wakho, ungumuntu onobuhlakani. Ngo-1996, esifundweni sakhe, uDkt Aikarakudy Alias wathi izinwele zesifuba zivame kakhulu phakathi kodokotela nabantu abafundile kakhulu. Lapho beqhathanisa impumelelo yabafundi ezifundweni, bathola ukuthi amadoda anoboya anamamaki aphezulu, kanti amanye amadoda ahlakaniphe kakhulu nawo anotshani obukhulu emhlane. Kodwa-ke, wonke umuntu owazalwa enamabele abushelelezi akufanele acasuke, ngoba phakathi kwamadoda ahlakaniphile kukhona amaningi “angenazinwele”, kufaka phakathi u-Albert Einstein.
8. Izinwele zomzimba zinemisipha
Izinwele zakho zomzimba empeleni zinamaseli emisipha. Ungakubona lokhu lapho imiphumela yokuqubuka kwama-goose noma ama-goosebumps aphuma esikhunjeni kwenzeka. Imisipha ebushelelezi yezinhlamvu zezinwele zisebenza ngaphansi kwezimo ezithile, njengokuchayelwa amakhaza, ukwesaba noma injabulo, izinwele ziphakama. Le reflex ibizwa ngokuthi i-piloerection.
9. Ehlobo, izinwele zomzimba zikhula ngokushesha
NgokukaBrian Thompson, uchwepheshe wezinwele waseMelika, izinwele zomzimba empeleni zikhula ngokushesha entwasahlobo nasehlobo. Kungani lokhu kwenzeka? Kuneziphakamiso zokuthi lokhu kungenxa yokugula okusheshayo kulezi zinyanga. Kunoma ikuphi, ukukhathazeka okukhula ngokushesha kwe-androgenic, okungukuthi, izinwele ekhanda nezinwele ezithinteka ngama-hormone.
10. Ukukhangwa ngocansi kuvela ezinweleni zomzimba
Yizinwele emzimbeni, hhayi ekhanda, ezisebenza njengendlela yokuheha abobulili obuhlukile. Ngakho-ke izinwele nezinwele ze-pubic ku-armpit zibambe futhi zifake isandla ekomiseni kwama-hormone akhethekile atholwe ngumzimba wethu, aze akhuphukele emoyeni futhi afinyelele umqondo wokuhogela ubulili obuhlukile.
Izinwele zomzimba wesilisa esifundeni se-lumbar namahlombe: amaqiniso ayi-10 angaziwa
Abamele ubulili besilisa banobunwele obukhulu - kulesi simo, kwakhiwa izinwele eziningi emzimbeni wowesilisa. Abanye abamele ubulili obunamandla banezinwele eziningi zomzimba futhi bayaziqhenya ngalo. Enye intsha, kunalokho, yehlisa ukuba izinwele zomzimba - kaningi, ehlobo. Ngokwezibalo, abantu abasha abaneminyaka engu-16- 24 ubudala ngabalandeli bokukhishwa kwezinwele emzimbeni: u-58% wabantu abasha uphuca izinwele zomzimba wabo wonke. Abesilisa abaneminyaka engama-50-65 ubudala, kunalokho, bayaziqhenya ngokuba izinwele zabo - bangama-22% kuphela, ngokusho kwezifundo, abasusa izinwele zomzimba wabo wonke.
Izinwele zomzimba zenza umsebenzi wokuvikela isikhumba
Ezimweni eziningi, abafana banamuhla bafuna ukuba nesikhumba esibushelelezi, ngokungafani noyise nokhokho babo. Ngokusho kocwaningo, ama-60% ezinsizwa azizwa enesidingo sokususa izinwele kuyo yonke imizimba yazo.
Ngaphezu kwalokho, embozweni kamagazini acwebezelayo, amadoda amaningi anezifuba ezibushelelezi. Lo mbhalo udingida amaqiniso amancane angaziwa ngobuhlakani besilisa, futhi uphendula futhi nombuzo wokuthi uzisusa kanjani izinwele ezingemuva.
Izinwele emzimbeni wesilisa: izimbangela zokukhula kwezinwele esibelethweni namanye amaqiniso angaziwa
Akubona bonke abafana abazi ukuthi izinwele ziqala ukukhula ngaphambi kokuba zizalwe. Ngokuqala kokuqala, akukho zinwele ezinganeni. Kodwa-ke, ngaphambi kokuzalwa kwengane yesilisa ilahlekelwa izinwele zayo zokuqala - i-lanugo.
AmaLanugos abhekwa njengezinwele ezondile ezakha emzimbeni wengane.
Futhi ngesikhathi sokuzalwa, ingane engakazalwa imbozwe nge-fluff yezinwele. Kodwa-ke, ngokushesha izinwele ezinjalo ziba zodwa - isikhumba sengane siba bushelelezi ngokuphelele.
Izinhlobo ezi-3 ezihlukene zezinwele zomzimba
ULanugo ubhekwa njengohlobo lokuqala lwezinwele. Ngemuva kokuvela kwe-lanugo emzimbeni wengane, ifomu lezinwele le-cannon. Azihlanganisi kwizindlala ze-sebaceous - ngaphansi kwamalambu nezinye izindawo.
Ngemuva kokuvela kovalo olunjalo ezinweleni zobusha, izinwele zezinduku ziqala ukukhula. Ziyakwazi eziqine, zikhule ezicutshini zesikhumba nasezindongeni ze-sebaceous - emaphethelweni nakwezinye izindawo. Ngenxa yalokho, le nsizwa inephunga lomzimba.
Amantombazane amaningi akhetha ubuhlakani bendoda obucocekile nobudingekayo
Ngabe amantombazane acabangani ngokuba izinwele zabafana? Kusukela ezikhumbuzweni zesikhathi esedlule, amantombazane abenombono ohlukile kobunyoninco besilisa - ubunwele bensizwa babubhekwa njengokwamukeleka emphakathini.
Okwamanje, abafana bafuna ukuthi amantombazane abe nesikhumba esibushelelezi esingenasici - noma yiluphi uhlaza emzimbeni wesifazane alwamukeleki.
Ngasikhathi sinye, ngokusho kwemiphumela yocwaningo oluhlukahlukene, amantombazane nawo afuna ukuthi laba bafana banakekele imizimba yabo futhi basuse izinwele ngokweqile - yize imvamisa yabesifazane kulolu daba inesizotha kakhulu kunaleyabesilisa.
Ngokusho kodokotela, ukususa u-hairness emlenzeni, ezingalweni nangaphansi kwemikhono kuwumsebenzi oyingozi. Wonke amadoda anezinwele ezifubeni zawo. Esimweni esifanayo, kunamaphoyinti amabili wokubukwa:
Futhi, amanye amadoda anezinwele emhlane - abesifazane abaningi abaphikisana nalokhu. Kodwa-ke, esimweni esifanayo, uma umfana ebheka umzimba wakhe, khona-ke ususa izinwele ngokweqile ngemuva.
Izinwele zamadoda zinokuvikelwa okuthembekile
Ebafaneni abasebasha, izinwele ze-cannon ziyayeka ukukhula - esikhundleni sazo, izinwele zezinduku ziqala ukukhula. Izinwele ze-Rod zakhiwa izindlala ze-sebaceous. Zivimbela amagciwane namagciwane ukuthi angangeni esikhunjeni nasolangeni. Lokhu kuhlanganiswa.
Kodwa-ke, amagciwane abola, okuholela ekutheni kube nephunga elingathandeki ngaphansi kwezingalo nakwezinye izindawo.
Esikhundleni sezinwele zomzimba esikhundleni samafutha
Njengamanje, ezinye izazi-mlando zikholelwa ukuthi ukubukeka kwezinwele emzimbeni womuntu kuhlotshaniswa nokwehla kwamafutha nokuphikisana nalokho.
Lapho behlala eduze nolwandle, abantu baba nezinwele ezimbalwa. Izinwele ezingatheni zikhula emzimbeni wesilisa, kwakulula ukuba indoda ibhukude futhi inhlanzi. Amafutha amaningi enzelwa ukulahlekelwa ukushisa komzimba.
Ubudlelwano benani lezinwele zomzimba namakhono endoda endoda
Ngokusho kwesinye isazi sokusebenza kwengqondo esivela e-United States, u-Aikarakudi Alias, ukuba izinwele kwabantu besilisa kuhlotshaniswa nobuhlakani bomuntu. Ngo-1996, udokotela wenza ucwaningo futhi wafinyelela esiphethweni sokuthi izinwele ezisefubeni emadodeni zivame ukukhula kubantu abanjalo:
Lapho etadisha ubunwele babafundi, udokotela waphetha ngokuthi abafana abanezimila ezinwele eziminyene esifubeni noma emuva bathola amamaki aphezulu kakhulu. Kodwa-ke, amadoda anesikhumba esibushelelezi awadikibali - kukhona abantu abakhaliphile phakathi kwabangenazinwele (ngokwesibonelo, u-Albert Einstein).
Izinwele emzimbeni zinemisipha
Izinwele ezisemzimbeni wesilisa zakhiwa amaseli emisipha. Imisipha yezinwele izenza zizizwe lapho umfana enamaqhubu noma amaqhubu esikhumba.
Imisipha yezinwele kwisivumelwano somzimba wesilisa nezinwele zikhuphuka zodwa ngaphansi kwezimo ezithile - ikakhulukazi, ekuxhumaneni namakhaza, ngokubonakala kokwesaba nakwezinye izimo.
Ezinyangeni ezifudumele, ukukhula kwezinwele zomzimba kuyasheshiswa
Ngokucwaninga kukaBrian Thompson, uchwepheshe wezifo zezinwele ezivela e-USA, izinwele ezisemzimbeni zikhula ngokushesha ngenkathi efudumele (entwasahlobo, ehlobo) kunasemakhazeni (ekwindla, ebusika).
Ngokusho kukadokotela waseMelika, entwasahlobo nasehlobo ezinweleni i-metabolism isheshisiwe, okuholela ekutheni kusebenze ukukhula kwawo. Kodwa-ke, ukukhula okusheshayo kubhekwa kuphela esikhumbeni nasenweleni le-pubic.
Ungasusa kanjani ngokuphelele izinwele ngokweqile: ukususwa kwezinwele ze-laser kanye nezinye izindlela zokususa izinwele
Ngosizo lwe-laser, ochwepheshe kuleli cala basusa izinwele emadodeni emzimbeni - izinwele ezingemuva elingaphansi emadodeni, izinwele emahlombe endoda nesifuba.
Ngaphezu kwalokho, ama-cosmetologists asusa izinwele ze-laser ezandleni zamadoda. Isikhathi sokususwa kwezinwele ze-laser yimizuzu engama-30, inani lamaseshini liyi-8. Imiphumela yokususwa kwezinwele ze-laser igcinwa isikhathi eside.
Ngemuva kokudlula kuzo zonke izikhathi zokususwa kwezinwele ze-laser, indoda kungenzeka ingayi salon izinyanga eziyisithupha - ngalesi sikhathi, izinwele azikhuli nhlobo ezindaweni eziphathwe ngedivayisi.
Razor for the back - ukususwa kwezinwele eziningi
Imisebe enjalo inama-1.5 intshi ama-blade, futhi isibambo eside. Ngosizo lwejazi elinjalo, amakhosi asusa izinwele ngemuva kwendoda, emahlombe nakumaqhubu nezinwele ezisemilenzeni yamadoda.
Isikhathi senqubo enjalo okungenani imizuzu engama-20. Kodwa-ke, ngemuva kwezinsuku ezimbalwa, izinwele ziphinde zivele endaweni efanayo.
Kukhona insingo ekhethekile yezindawo okulula ukufinyelela kuzo emzimbeni
Ngenxa yalokhu, ukuze ususe izinwele ngokuphelele, kungcono ukubonana nochwepheshe kule ndaba futhi ususe izinwele ze-laser.
