Zina mwa zinthu zomwe zimakhudza mapangidwe a makwinya pakhungu

Kutanthauzira kwenikweni kwa makhalidwe enieni a minofu ya khungu ndi kapangidwe kathu ka khungu. Kamakhala ndi anthu akabadwa. Kamakhala ndi mipata ya khungu yozungulira ndi ma crests a khungu, omwe nthawi zambiri amakhala ma polygon okhazikika ndipo sasintha kwenikweni. Mukayang'ana khungu lopanda kanthu, mutha kuwona mawonekedwe ovuta komanso osokonezeka, komanso tsitsi lopyapyala lolemera kapena lopepuka. Komabe, pakapita nthawi, anthu amapitirira kukalamba, ndipo khungu limakalamba pang'onopang'ono mwachibadwa. Nthawi yomweyo, khungu lomwe nthawi zambiri limaonekera lidzavutikanso ndi zinthu zakunja monga kuipitsidwa kwa chilengedwe, ndipo likupitiriza kuvulala, ndipo kuchuluka kwa kuwonongeka kwa maselo a stratum corneum kudzasintha. Chiwerengero cha mipata ya khungu ndi mikwingwirima ya khungu chikusintha, ndipo mawonekedwe okhazikika amawonekanso ogwirizana, chiwerengerocho chimachepa, ndipo malo a pamwamba akupitiriza kukula, kotero khungu limakhala lokwinya komanso lolimba.
Kawirikawiri, munthu asanakwanitse zaka 25, pamwamba pa khungu pamakhala posalala, powala, komanso potambasuka. Komabe, pambuyo pake, khungu limayamba kukalamba pang'onopang'ono ndipo zizindikiro za thupi nthawi zambiri zimasintha.
1. Chinyezi pakhungu ndi chotchinga pakhungu
Kafukufuku wambiri pa khungu louma amayang'ana kwambiri ntchito za stratum corneum, monga ntchito ya kusunga madzi ndi ntchito ya chotchinga cha khungu. Monga kuphunzira za chinyezi, zinthu zachilengedwe zonyowetsa, ndi kusintha kwa mafuta pakati pa maselo a stratum corneum. Kutayika kwa chinyezi kumakhala kwakukulu, zomwe zimapangitsa kuti khungu likhale losalimba komanso lopanda tinthu. Kutuluka kwa maselo a epidermal kumasokonekera, zomwe zimapangitsa kuti pakhale dandruff ndi mamba. Kuchuluka kwa chinyezi pakhungu kumagwirizana kwambiri ndi chinyezi, kunyezimira ndi kusalala kwa khungu. Kusalala, madzi ambiri a stratum corneum kumaonekera nthawi zonse kuti apange kuwala kowala, pomwe stratum corneum youma, yokhala ndi mamba imaonekera mwanjira yosadziwika bwino yomwe imapangitsa khungu kuwoneka imvi. Pakhungu lokhala ndi chinyezi chochepa, khungu limakhala louma komanso louma, ndipo khungu limakhala lopanda kanthu.
Khungu lokhala ndi ntchito yochepetsera zotchinga lili ngati ambulera yosweka. Sikuti madzi achilengedwe amangotuluka mosavuta, komanso zinthu zakunja zimakhala zosavuta kulowa, ndipo kutupa kumachitikanso. Monga mavuto a pakhungu okhudzana ndi kutupa: kuyabwa, kuuma, kutsekeka, kuyabwa, kufiira, ndi zina zotero. Mavuto obwerezabwereza a pakhungu omwe amayamba chifukwa cha mtundu wa khungu komanso kutupa kosatha mkati mwa khungu.
Chigoba cha khungu chomwe chimaoneka ngati kuwala kwa dzuwa chinasonyeza kukhuthala kokonzanso pamene kuwonongeka kunali kocheperako, ndi kufooka pamene kuwonongeka kunali kwakukulu. Maselo a basal layer anasinthidwa ndi atypia yodziwikiratu, ndipo panali maselo ambiri a dyskeratotic.
2. Dermis imataya kusinthasintha kwake
Kuuma kwa khungu kumagwirizana kwambiri ndi kuuma kwa khungu. Kuuma kwa khungu kumachepa, kuuma kwa khungu kapena makwinya kumawonekera, ndipo kuuma kwa khungu kumawonjezeka. Ma Fibroblast ndi gawo lofunika kwambiri la maselo mu dermis ya khungu ndipo amachita gawo lofunikira pakupanga ulusi wotulutsa ndi matrix yakunja. Amagwira ntchito yofunika kwambiri pakukonzanso mabala a minofu. Ndi ukalamba, makulidwe a khungu amachepa pamene kuchuluka kwa ulusi wotanuka pakhungu kumachepa pang'onopang'ono. Kukalamba kwa khungu kumaonekera kwambiri, komwe kumatha kuchitika ngati khungu louma komanso losalimba, makwinya owonjezeka komanso ozama, khungu lotayirira, komanso kuchepa kwa kuuma. Ukalamba umayenderana ndi kuchepa kwa kuchuluka kwa mapuloteni a khungu, kusowa kwa kulimba pakhungu, komanso kuchuluka kwa kapangidwe ka khungu komwe kumabweretsa mawonekedwe a makwinya.
Kotero mavuto a pakhungu asanayambe, timakhala ndi zochita zambiri. Mwachitsanzo,chowunikira khungukungatithandize kuchepetsa kapena kuthetsa mavuto a pakhungu mpaka kufika pamlingo winawake mavuto a pakhungu asanayambe kuonekera!
