Izindaba ezimangalisayo zesikhumba sethu (Isikhumba Somuntu): Masifunde kalula!

Wake wazibuka esibukweni wacabanga, 'Luhlobo luni lwesikhumba lolu? Kungani lubaluleke kangaka kithi?'? Mhlawumbe awuzange ube nesikhathi sokucabanga ngakho. Kodwa, lesi 'sikhumba' esinaso emzimbeni wethu siyisitho esimangalisayo ngempela. Namuhla, ake sixoxe ngesikhumba sethu nezinto ezenzeka kuso, njengokungathi sikhuluma nomngane.

Ngakho-ke, siyini lesi 'sikhumba'?

Kalula nje, isikhumba yisitho esikhulu kunazo zonke emzimbeni wethu. Yebo, ukuzwile lokho kahle, isitho esikhulu kunazo zonke! Cabanga nje, umzimba wethu wonke umbozwe yilesi sikhumba. Kunezigidi zamangqamuzana amancane kuwo wonke amasentimitha esikhumba sakho. Akukhona lokho kuphela, kodwa ngaphakathi kwalesi sikhumba kukhona izindlala zokujuluka, izindlala ezikhiqiza uwoyela, iziphetho zemizwa (njengezimpondo ezincane ezibamba imizwa), kanye nemithambo yegazi eminingi. Konke lokhu kusebenza ndawonye ukwenza isikhumba sisebenze.

Ngakho-ke, yiziphi izinzuzo esinazo lesi sikhumba kithi?

Isikhumba sethu asisona nje isimbozo somzimba wethu. Sisinikeza izinsizakalo eziningi. Ake sibheke ukuthi ziyini.

• Kuvikela izitho ezibalulekile emzimbeni: Cabanga nje, zonke izitho zethu ezibalulekile njengenhliziyo, amaphaphu nezinso zingaphakathi emzimbeni. Isikhumba sifana nesivikelo salezi zinto. Yingakho ngisho nokusikeka okuncane noma ukusikeka kungalimazi ngqo izitho zangaphakathi.
• Isebenza njengesivikelo: Mangaki amakhemikhali ayingozi akhona endaweni esizungezile? Ngenxa yokuthi sinesikhumba, lezi zinto azingeni kalula emzimbeni. Kufana nesembatho esivikelayo esiqinile emizimbeni yethu. Yingakho singaguli ngaso sonke isikhathi.
• Kuvikela ekulimaleni: Uma sigijima, sidlala, siwa, noma sishayisana nento ethile, isikhumba sisiza ukuvikela izicubu ezithambile ngaphakathi ekulimaleni okukhulu. Kufana nomatrasi obamba ukushaqeka .
• Ilawula izinga lokushisa lomzimba: Uma sizizwa sishisa, umjuluko ukhiqizwa yizindlala zokujuluka esikhumbeni. Njengoba umjuluko uphuma, umzimba uyaphola. Futhi, ngezinsuku ezibandayo, isikhumba sisiza ukusigcina sifudumele ngokunciphisa ukulahleka kokushisa komzimba. Akumangalisi lokho?
• Ukulawulwa Kwamanzi: Isikhumba sivimbela amanzi angaphakathi emzimbeni wethu ukuthi angahwamuki. Ngaphandle kwalokho, singaphelelwa amanzi ngokushesha. Futhi, lapho sigeza noma sibhukuda, isikhumba sivimbela amanzi ukuthi angamuncwa emzimbeni. Ngaphandle kwalokho, besizomunca amanzi njengesiponji bese sivuvukala, akunjalo?
• Inikeza imizwa: Sizwa ukushisa, ukubanda, ubuhlungu bento esihlabayo, ukuthinta okuthambile komuntu osithintayo... Konke lokhu kuzwakala ngeziphetho zemizwa ezikhethekile esikhumbeni. Lokhu kufana nezinzwa ezincane ezithumela ulwazi ebuchosheni. Yingakho futhi singabalekela ingozi.

Ngakho-ke, lesi sikhumba sakheka kanjani? Ziyini izingqimba zesikhumba?

Kulungile, manje ake sibheke ukuthi lesi sikhumba esimangalisayo senziwe kanjani. Empeleni kunezingqimba ezintathu zesikhumba. Sifana nekhekhe elingqimba.

1. Isendlalelo esiphezulu: `(Epidermis)`

2. Ingqimba ephakathi: `(Isikhumba)` (Isikhumba)

3.Isendlalelo esingezansi: `(Izicubu ezingaphansi kwesikhumba)`

Lezi zingqimba ezintathu zisebenza ndawonye njengeqembu ukwenza wonke umsebenzi esiwukhulume ngaphambilini. Ake sixoxe ngengxenye ngayinye yalezi zingqimba ngemininingwane ethe xaxa, kulungile?

I-Epidermis - ungqimba oluvikelayo lwesikhumba esilubonayo

I-`(Epidermis)` yingxenye yesikhumba wena, mina, kanye nathi sonke esingayibona. Lena ungqimba oluphezulu, oluvikelayo lwesikhumba. Lufana nodonga olungaphandle lwenqaba. Luncane kakhulu kwezinye izindawo, njengezibuko zethu, isibonelo. Kodwa, ngakolunye uhlangothi, ezindaweni ezidinga ukuvikelwa okwengeziwe, njengezintende zethu nezinyawo zethu, le `(Epidermis)` ikhuluphele.

Kuyamangalisa ukucabanga ukuthi isikhumba sethu sishintsha kanjani kusuka endaweni kuya endaweni kuye ngezidingo zaso!

Enye into ekhethekile ngale `(i-Epidermis)` ukuthi ikhiqiza njalo amaseli amasha. Njengoba amaseli amadala efa futhi ewa, amaseli amasha ayakhuphuka kusukela ongqimbeni olungezansi ukuze awathathe indawo yawo. Le nqubo yonke, okungukuthi, ithatha cishe izinsuku ezingu-28, noma cishe inyanga, ukuthi iseli elisha likhule, likhuphukele phezulu, bese liwa. Ngakho-ke uyazi, uthola isikhumba esisha cishe njalo ngenyanga!

Kunezinhlobo ezintathu eziyinhloko zamaseli ku-epidermis, ngayinye enomsebenzi othize:

• `Ama-Melanocyte` - Lawo anikeza umbala wesikhumba: Lawa maseli akhiqiza umbala ` (Melanin) ` (Melanin). Isikhumba nezinwele zethu zithola umbala wazo ngenxa yalokhu ` (Melanin) . Abanye abantu banesikhumba esimnyama, abanye banesikhumba esikhanyayo, kanti abanye banesikhumba esimhlophe. Isizathu salokho inani ` ( Melanin ) . Labo abanesikhumba esimnyama kakhulu banesikhumba esimnyama, kanti labo abanesikhumba esincane banesikhumba esikhanyayo. Uma siphuma elangeni, lapho sichayeka elangeni, la maseli ` (Melanocyte) ` ayashukunyiswa futhi akhiqize ` (Melanin) amaningi. Yingakho uma siphuma elangeni, isikhumba sethu siba mnyama kancane, noma abanye abantu baba namabala amnyama. Empeleni lokhu kuyinto isikhumba esiyenzayo ukuze sizivikele emisebeni yelanga eyingozi.
• Ama-Keratinocyte - Amandla esikhumba nokuvikelwa: Lawa maseli akhiqiza uhlobo olukhethekile lweprotheyini ebizwa ngokuthi i-Keratin . Izinwele zethu nezinzipho zenziwe ngale protheyini efanayo . Yile protheyini enikeza isikhumba amandla nokuqina, futhi isebenza njengesivikelo sokuvikela isikhumba kumagciwane angaphandle kanye nokulimala okuncane.
• Amaseli eLangerhans - Amasosha omzimba esikhumba: Lawa maseli ayingxenye yesimiso somzimba wethu sokuzivikela. Njengamasosha amancane, asiza ekuboneni nasekulweni nezinto ezithathelwanayo ezizama ukungena emzimbeni ngesikhumba.

I-Dermis - Isikhungo esimatasa sesikhumba

Ngaphansi kwe-epidermis, ungqimba oluphakathi lwesikhumba, kukhona i- dermis . Lokhu kukhulu kune-epidermis. Yilapho iningi lomsebenzi obalulekile wesikhumba lenzeka khona. Kufana nedolobha elimatasa.

Le `(Dermis)` yakhiwe kakhulu ngezinhlobo ezimbili zemicu:

• ` ( I-Collagen): Yilokhu okunikeza isikhumba amandla nokuqina kwaso. Lokhu kubaluleke kakhulu ekugcineni isikhumba sibukeka sisesisha.
• ` (Elastin) ` (Elastin): Lokhu kunikeza isikhumba ukuguquguquka kwaso. Lokho kusho ukuthi uma isikhumba seluliwe futhi sikhululwa, sibuyela esimweni saso sokuqala, futhi yilokho ` (Elastin) ` okusiza ngakho. Kufana nebhande lerabha.

Njengoba siguga, ukukhiqizwa kwe-" Collagen" kanye ne-" Elastin" kuyancipha. Yingakho isikhumba siqala ukushwabana nokuwa njengoba siguga.

Akuzona lezi zindwangu kuphela, kunezinto eziningi ezibaluleke kakhulu ngaphakathi kwe-`(Dermis)`:

• Imithambo yegazi: Le mithambo yegazi inikeza ungqimba olungaphezulu, i-epidermis, izakhamzimba nomoya-mpilo. Lokhu kudla kubalulekile ekukhuleni kwamangqamuzana amasha ku-epidermis. Ngezinye izikhathi, lapho sinamahloni noma sesaba, ubuso bethu buba bomvu ngoba le mithambo yegazi iyavuleka.
• Iziphetho zemizwa: Njengoba sesixoxile kakade, konke esikuzwayo, njengobuhlungu, izinga lokushisa (elishisayo/elibandayo), ingcindezi, ukuthinta, njll., kwenziwa kube nokwenzeka yiziphetho zemizwa ku-`(Dermis)`. Ngaphandle kwalokhu, besingeke sizwe lutho.
• Izindlala zokujuluka: Lezi zindlala zikhiqiza umjuluko, okusiza ekulawuleni izinga lokushisa lomzimba. Uma umjuluko uphuma esikhumbeni, uyapholisa umzimba.
• Ama-follicle ezinwele: Zonke izinwele emzimbeni wethu ziqala ku-follicle encane e-dermis. Impande yezinwele itholakala lapha.
• Izindlala ze-Sebaceous - Abakhiqizi bamafutha esikhumba: Lezi zindlala zikhiqiza into enamafutha ebizwa ngokuthi i-sebum . Le sebum igcina isikhumba sibushelelezi futhi sinomswakama. Iphinde isize ukugcina isikhumba singangeni manzi. Ngezinye izikhathi, i-sebum eningi kakhulu ingabangela induna.

`(Izicubu ezingaphansi kwesikhumba)` (izicubu ezingaphansi kwesikhumba) - ukuvikelwa nokufudumala kwengqimba ejulile

Manje sesifika ongqimbeni olujulile, noma oluphansi, lwesikhumba. Lokhu kubizwa ngokuthi " izicubu ezingaphansi kwesikhumba " noma ngezinye izikhathi "iHypodermis". Ilele ngaphansi "kwe-Dermis", ngqo ngaphezu kwemisipha namathambo.

Lolu ngqimba lwakhiwe kakhulu ngamafutha . Lolu ngqimba olunamafutha lusinikeza izinzuzo eziningana:

• Isivikelo esifana nesicamelo: Uma siwa noma sishayisa okuthile, kuyamunca ukushaqeka ngaphandle kokulimaza ngqo amathambo noma izitho zangaphakathi, kuhlinzeke ngesivikelo njengomatilasi.
• Igcina umzimba ufudumele: Lolu ngqimba lwamafutha lusebenza njenge-'insulator', luvimbela ukushisa komzimba ukuba kuphume, lusisize ekusivikeleni emakhazeni futhi lusigcine sifudumele. Yingakho izilwane emazweni abandayo zinongqimba olukhulu lwamafutha emizimbeni yazo.
• Amandla agcinwa:Amandla agcinwa kulolu ngqimba njengamafutha ukuze asetshenziswe uma kudingeka. Yilapho umzimba uthola khona amandla uma singadli.

Ngakho ungabona ukuthi lezi zingqimba ezintathu zesikhumba zibaluleke kangakanani, nokuthi zihlobene kangakanani nokuthi zisebenzelana kangakanani nemizimba yethu.

Ngakho-ke, uyini umyalezo okufanele siwuthathe ekhaya kulokho esikufundile namuhla?

Isikhumba sethu asiyona nje igobolondo, siyisivikelo esimangalisayo, esisebenza ngezindlela eziningi, isilawuli, kanye nenzwa emzimbeni wethu.

• Kunezingqimba ezintathu eziyinhloko zesikhumba: i-epidermis, i-dermis, kanye nezicubu ezingaphansi kwesikhumba. Ngayinye yalezi zihlukile.
• Ngayinye yalezi zendlalelo ibalulekile ekuvikeleni kwethu, ekulawuleni izinga lokushisa lomzimba, ekuhlinzekeni ngemizwa, nokunye okuningi. Uma ungqimba olulodwa lungasebenzi kahle, singaba nezinkinga eziningi.
• Ukunakekela isikhumba sakho kahle, okusho ukusigcina sihlanzekile, ukusithambisa, nokusivikela emisebeni yelanga eyingozi, kubaluleke kakhulu empilweni yethu iyonke.
