Ingabe kufanele sazi kahle ungqimba oluphakathi lwesikhumba sethu, i-dermis?

Wake wazibuza ukuthi isikhumba sakho sisebenza kahle kangakanani? Isikhumba sethu asisona nje isembozo somzimba wethu. Siyisitho esiyinkimbinkimbi nesibalulekile. Isikhumba sethu sakhiwe ngezingqimba ezintathu eziyinhloko. Namuhla sizokhuluma ngezingqimba ezibaluleke kakhulu kulezi, ungqimba oluphakathi. Silubiza ngokuthi i-dermis . Ngezinye izikhathi lubizwa ngokuthi i-corium , okuyigama lesiLatini elisho "isikhumba."

Iyini i-dermis? Kalula nje...

Kalula nje, ungqimba oluphakathi lwesikhumba sakho yi-dermis. Ungqimba oluphezulu lubizwa ngokuthi i-epidermis, kanti ungqimba olungezansi lubizwa ngokuthi i-hypodermis. Ngakho-ke i-dermis itholakala phakathi kongqimba oluphezulu nongqimba olungezansi.

Cabanga ngakho njengesandwich. Ucezu oluphezulu lwesinkwa luyi-epidermis, ucezu olungezansi luyi-hypodermis. Ukugcwalisa okumnandi phakathi yi-dermis. Ngaphakathi kwale dermis, kunezinye izendlalelo ezimbili zazo. Ake sibheke nalokho futhi.

Yiziphi izingqimba ezimbili eziku-dermis?

Yebo, le dermis ayilona ungqimba olulodwa. Kunezinye izingxenye ezimbili ngaphakathi kwayo. Yilezi:

1. I-Reticular Dermis - ungqimba olungezansi

Lena ingxenye ejiyile kakhulu ye-dermis, ngaphansi kwayo. Kufana nesisekelo sendlu. Kungaphakathi kwalokhu lapho kutholakala khona izinto eziningi ezibaluleke kakhulu esikhumbeni sethu.

• Imithambo yegazi: Yilokhu okuletha ukudla okudingekile esikhumbeni.
• Izindlala: Izinto ezifana nezindlala zokujuluka, izindlala ze-sebaceous (ezikhiqiza uwoyela).
• Izinwele ezinde: Yilapho izinwele emzimbeni wethu zikhula khona.
• Ama-lymphatics: Ahlobene nesimiso somzimba sokuzivikela.
• Imizwa: Lokhu kunikeza umuzwa.
• Amaseli amafutha.

Le dermis ye-reticular izungezwe inethiwekhi ye -elastin kanye ne-collagen fibers. Cabanga ngale ndlela: i-elastin ifana nebhande lerabha, kanti i-collagen ifana nentambo eqinile. Lezi ezimbili zinika isikhumba sethu amandla nokuguquguquka kwaso. Lezi ezimbili zisivumela ukuthi selule futhi selule isikhumba sethu.

2. I-Papillary Dermis - Isendlalelo esiphezulu

Lolu ungqimba oluncane kancane phezu kwe-dermis. Lukhulu kune-dermis ye-reticular. Lunemisebenzi eminingana ebalulekile:

• Imicu ye-Collagen.
• Amaseli e-Fibroblast: Lawa amaseli asiza ekwenzeni izinto ezifana ne-collagen.
• Amaseli amafutha.
• Ama-capillary loops: Asiza ukondla i-epidermis.
• Imicu yezinzwa.
• Ama-touch receptors (isib. ama-corpuscle kaMeissner): asisize sizizwe ukuthinta.
• Amaseli alwa namagciwane (ama-phagocyte): Njengabalindi esikhumbeni sethu.

Le dermis ye-papillary ifinyelela engqimbeni engaphansi ye-epidermis. Lezi zingqimba ezimbili zixhumene njengeminwe yezandla zethu ihlangene . Yingakho kukhona isibopho esiqinile phakathi kwengqimba ephezulu nengqimba ephakathi.

Ngakho-ke umehluko phakathi kwe-dermis ne-epidermis uyini?

Manje njengoba usunomqondo omncane ngalezi zingqimba ezimbili, ake sichaze kabanzi.

• I-Epidermis: Lena ungqimba olungaphandle noluncane kakhulu lwesikhumba sethu. Lufana nezingubo zethu. Lugcina imizimba yethu inamanzi, lwenza amangqamuzana esikhumba amasha, futhi lusivikele ekulimaleni kwangaphandle (njengokusikeka, imihuzuko, namagciwane). Yilapho futhi kwenziwa khona i-melanin enikeza isikhumba sethu umbala wayo.

• I-Dermis: Lena ungqimba oluphakathi nolukhulu kakhulu lwesikhumba . Lukhulu kakhulu kune-epidermis. Luqukethe i-collagen ne-elastin, okunikeza isikhumba amandla aso, ukujiya, kanye nesakhiwo sokusekela.

Cabanga nje, uma i-epidermis ifana nophahla lwendlu, i-dermis iyizindonga nezinsika ezibamba lolo phahla ndawonye.

Izicubu ezixhumeneyo, iziphetho zemizwa, izindlala zokujuluka, izindlala zamafutha, kanye nezimbotshana zezinwele esikhumbeni sethu konke kutholakala ngaphakathi kwesikhumba. Lokhu kusho ukuthi iningi "labasebenzi" besikhumba litholakala lapha.

Yiziphi izinsizakalo ezinikezwa yi-dermis emizimbeni yethu?

Zonke izingqimba zesikhumba sethu zisebenza ndawonye ukuvikela imizimba yethu. Phakathi kwazo, i-dermis inemisebenzi eminingi ekhethekile. Bheka:

• Isekela i-Epidermis: I-dermis inikeza ukwesekwa okuhle kwengqimba ephezulu ngenxa yesakhiwo sayo esiqinile kanye nokunwebeka kwayo. Futhi, imithambo yegazi e-dermis ithwala izakhamzimba ezidingekayo iye e-epidermis.
• Kusenza sikwazi ukuzwa imizwa ehlukahlukene: Iziphetho zemizwa ku-dermis yizo ezisenza sikwazi ukuzwa izinto ezifana nokucindezeleka, ubuhlungu, ukushisa, ukubanda, kanye nokulunywa . Cabanga ngakho, ukulunywa umiyane kuyabuhlungu, i-ice cube izwakala ibanda - zonke lezi zimpawu zivela ku-dermis.
• Ukujuluka kuyavela: Ingabe uyajuluka uma uzizwa ushisa noma ucindezelekile? Lokho kujuluka kukhiqizwa yizindlala zokujuluka eziku-dermis. Uma sijuluka,Izinga lokushisa lomzimba liyalawulwa (ukushisa komzimba) .
• Igcina isikhumba simanzi: I-dermis iqukethe izindlala ze-sebaceous . Lezi zikhipha into enamafutha ebizwa ngokuthi i-sebum . Le sebum yiyo egcina isikhumba nezinwele zethu zimanzi futhi zicwebezela, ngaphandle kokuzomisa.
• Izinwele ziyakhiqizwa: Izinwele zikhiqizwa ngama -follicle ezinwele ku-dermis, cishe yonke indawo emzimbeni ngaphandle kwezintende zezandla zethu kanye nezinyawo zethu.

I-dermis izisiza kanjani ezinye izitho zomzimba?

Kanye nezinye izendlalelo zesikhumba, i-dermis ivikela uhlelo lwethu lwamathambo, izitho zangaphakathi, imisipha, kanye nezicubu ekulimaleni kwangaphandle, njengegobolondo elivikelayo.

Ikuphi i-dermis? Ingakanani? Yenziwe ngani?

Njengoba sishilo ngaphambili, i-dermis iwungqimba oluphakathi kwesikhumba, olutholakala phakathi kwe-epidermis kanye ne-hypodermis.

Ubukhulu balokhu buyahlukahluka kuye ngendawo emzimbeni. Isibonelo, buncane kakhulu ezinkopheni, cishe bungamamilimitha angu-0.6 . Kodwa ngemuva, bungaba ngamamilimitha angu-4 ubukhulu .

I-dermis yakhiwe kakhulu ngezicubu ezinemithambo yegazi eminingi. Iphinde iqukethwe:

• I-Collagen
• I-Elastin
• Uketshezi olucacile, olufana nejeli (into egayiwe) olugcwalisa izikhala phakathi kwamaseli nemicu.
• Izindlala ezahlukahlukene ezifana nezindlala zokujuluka kanye nezindlala ze-sebaceous.
• Izinwele ezinde .

Zikhona yini izifo ezithinta i-dermis?

Yebo, impela. Kunezimo eziningi ezahlukene kanye nezinkinga ezingathinta i-dermis. Nazi izibonelo ezimbalwa:

• I-Ehlers-Danlos syndrome: Lesi yisimo sofuzo esithinta isikhumba, amalunga, kanye nemithambo yegazi.
• I-Urticaria / Amaqhubu: Isimo lapho kuvela khona ukuqubuka kwamaqhubu abomvu, abomvu, aphakanyisiwe esikhumbeni ngokuzumayo.
• I-Marfan syndrome: Lesi futhi yisimo sofuzo esithinta izicubu ezixhumeneyo.
• I-melanoma yesikhumba eyinhloko: Uhlobo oluyingozi lomdlavuza wesikhumba.
• I-Solar elastosis: Ukulimala kwesikhumba okubangelwa ukuchayeka elangeni isikhathi eside.
• I-Systemic sclerosis (scleroderma): Isifo lapho isikhumba siba lukhuni futhi siqine khona.
• Amaqhubu: Kunezinhlobo ezahlukene zamaqhubu angavela esikhumbeni.

Yiziphi izici ezivamile zalezi zinhlobo zezinkinga ze-dermis?

Nazi ezinye izimpawu ezivamile ezingase zivele ezimweni ezithinta i-dermis:

• Ukukhipha igazi noma olunye uketshezi oluvela emithanjeni noma emaphashini lungena ezicutshini .
• Izinguquko emathanjeni, emehlweni, emaphashini, esikhumbeni, enhliziyweni, nasemithanjeni yegazi .
• Amabala amnyama, alumayo esikhumbeni.
• Ngokungavamile, kulula ukugwazwa .
• Ukunyakaza okukhulu kwamalunga .
• Isikhumba sibushelelezi kakhulu, sincane, futhi sinwebeka kakhulu kunokujwayelekile .
• Ukuvuvukala kwezicubu .
• Amabala afana ne-eczema (ama-Welts) .

Uma unalezi zimpawu, kungcono ukufuna iseluleko sikadokotela.

Yiziphi izivivinyo ezenziwayo ukuhlola impilo yesikhumba?

Odokotela benza izivivinyo ezahlukene ukuze bathole ukuthi kunenkinga yini ngesikhumba. Ezinye zazo zifaka:

• Ukuhlolwa kofuzo: Lokhu kungasiza ekuxilongeni izimo ezithile (isib. i-Ehlers-Danlos syndrome).
• I-biopsy yesikhumba: Kuthathwa ingxenye encane yesikhumba bese ihlolwa ngaphansi kwe-microscope ukuze kuhlolwe isifo, ukutheleleka, noma umdlavuza.
• Isikeni se-Magnetic Resonance Imaging (MRI): Singasetshenziswa ukuhlola izimila ezinomdlavuza, njenge-melanoma, ebuchosheni noma emgogodleni.
• Ukuskena kwe-Positron Emission Tomography (PET): Lokhu kusiza ukubona ukuthi umdlavuza ususakazekele yini kuma-lymph node noma kwezinye izingxenye zomzimba ezikude nendawo yokuqala.

Yiziphi izindlela zokwelapha izifo zesikhumba?

Nazi ezinye izindlela zokwelapha izimo ezithinta i-dermis:

• Ama-Corticosteroids: Lawa uhlobo lomuthi onciphisa ukuvuvukala kanye nokulimala kwezicubu. Anganikezwa njengokhilimu noma amaphilisi.
• Ukufakelwa kwesikhumba: Le nqubo isetshenziselwa ukwelapha isikhumba esonakele esingakwazi ukupholisa ngokwaso. Ingasiza abantu abanomonakalo omkhulu wesikhumba ngenxa yezinto ezifana nokusha, izifo ezinzima, kanye nezilonda.
• Izinto ezithatha indawo yesikhumba: Lokhu kufaka phakathi ama-allograft, ama-xenograft, noma isikhumba esenziwe ngama-molecule angewona awezinto eziphilayo kanye nama-polymer. Lokhu kuwusizo kubantu abanezilonda zesikhumba ezijulile, ukusha, kanye nezifo.

Izinto ezilula esingazenza ukuze sigcine i-dermis iphilile: Lokho esingakwenza!

Manje usuyazi ukuthi i-dermis ibaluleke kangakanani. Ngakho-ke sidinga ukusebenza kanzima ukuze siyigcine iphilile. Nazi ezinye izinto ezilula ongazenza:

• Yakha imikhuba emihle yokunakekela isikhumba:
• Phuza okungenani izingilazi zamanzi ezingu-8 ngosuku. Kubaluleke kakhulu ukumanzisa umzimba ngaphakathi.
• Sebenzisa insipho ethambile kanye nezihlanzi ezingalimazi isikhumba.
