Isikhumba sethu asisona nje isimbozo, sinjengesihlangu esimangalisayo esivikela konke okungaphakathi emzimbeni wethu. Namuhla, ake sixoxe ngalesi sikhumba esimangalisayo.

Kalula nje, siyini lesi sikhumba?

Isikhumba sethu siyisitho esiyinkimbinkimbi esakhiwe ngokuyinhloko ngamanzi, amaprotheni, amafutha, kanye namaminerali. Njengodonga, isikhumba sethu sivimbela amagciwane ukuthi angangeni emzimbeni.

• I-Hypodermis: Ungqimba olunamafutha olungaphansi.

Manje ake sibheke ngayinye yalezi zingqimba ngokwehlukana.

1. I-Epidermis - ungqimba oluphezulu esilubonayo

Lona umvikeli wesikhumba sethu. Uyabona, lolu ngqimba oluphezulu oluthintayo lwenza umsebenzi omningi. Amaseli akulolu ngqimba enziwe ngeprotheni ekhethekile ebizwa ngokuthi ``Keratin.''

• Isebenza njengesivikelo: Lolu ngqimba luvimbela amagciwane anjengamabhaktheriya namagciwane ukuthi angangeni emzimbeni, ahlangane negazi, futhi abangele izifo. Luphinde luvikele umzimba ezintweni zangaphandle njengemvula nelanga.
• Isikhumba Esisha: Ubuwazi ukuthi isikhumba sakho sizivuselela njalo? Isikhumba sihlala sikhiqiza amangqamuzana esikhumba amasha. Nsuku zonke, imizimba yethu ikhipha amangqamuzana esikhumba amadala angaba ngu-40,000. Lawa maseli amasha ayathathelwa indawo.

• Umbala wesikhumba:Isikhumba sethu, izinwele, namehlo zithola umbala wazo ku-pigment ebizwa ngokuthi ``Melanin``. Lo mbala utholakala ku-epidermis. Uma umzimba womuntu ukhiqiza i-melanin eningi kakhulu, umbala wesikhumba walowo muntu uba mnyama. Yingakho uba mnyama ngokushesha uma ubekwe elangeni.

2. I-Dermis - Ingqimba ebaluleke kakhulu phakathi

Lolu ngqimba oluphakathi lwakha u-90% wobukhulu besikhumba sonke. Eqinisweni, umsebenzi omningi obaluleke kakhulu wesikhumba wenzeka lapha.

• Amandla nokuguquguquka: Izinhlobo ezimbili zamaprotheni ezibizwa ngokuthi `(Collagen)` kanye `(Elastin)` zitholakala kulolu ngqimba. Cabanga nge-collagen njengezinsika zekhonkrithi ezinika isikhumba sethu amandla. I-Elastin ifana namabhande e-elastic phakathi kwalezo zinsika. Kungenxa yale-elastin ukuthi isikhumba sibuyela esimweni saso sokuqala ngemva kokwelulwa.
• Ukukhula kwezinwele: Izimpande zezinwele zethu nomzimba wethu zikulolu ngqimba lwe-dermis.
• Inzwa yokuthinta: Ungazizwa into eshisayo, ebandayo, eklwebhekayo, noma ebushelelezi kakhulu ngenxa yemizwa ekulolu ngqimba. Le mizwa nayo inesibopho sokuzwa ubuhlungu.
• Ukukhiqizwa kwamafutha: Ama-oyela alesi sigaba akhiqiza amafutha adingwa yisikhumba. Lawa mafutha yiwo agcina isikhumba sibushelelezi futhi asivimbele ukuthi some. Futhi yisona sizathu esenza isikhumba sakho singamunci amanzi amaningi uma ugeza noma umanzi emvuleni.
• Ukukhiqizwa kojuju: Izindlala zojuju nazo zitholakala kulolu ngqimba. Ukushisa komzimba kulawulwa lapho ukujujuka kuphuma ebusweni besikhumba.
• Ukuhlinzekwa kwegazi: I-epidermis (ungqimba oluphezulu) ithola izakhamzimba zayo emithanjeni yegazi emincane e-dermis.

3. I-Hypodermis - ungqimba olunamafutha olungaphansi

Lolu ungqimba olungezansi lwesikhumba. Lwakhiwe kakhulu ngamafutha.

• Ukuvikela imisipha namathambo: Zicabange uwa. Amathambo nemisipha yakho kuvikelekile ekulimaleni ngoba lolu ngqimba lwamafutha olungaphansi lusebenza 'njengesithambisi sokushaqeka'.
• Ukuba khona kwezicubu ezixhumene: Isikhumba sixhunywe emisipheni namathambo yizicubu ezixhumene kulolu ngqimba.
• Ukusiza imizwa nemithambo yegazi: Imizwa nemithambo yegazi evela ku-dermis iyanda kulolu ngqimba futhi ixhumane nezinye izingxenye zomzimba.

Yini esingayenza ukuze sigcine isikhumba sethu siphilile?

Njengoba siguga, inani le-`(Collagen)` kanye ne-`(Elastin)` esikhumbeni sethu liyancipha. Lokhu kubangela ukuthi ungqimba oluphakathi lwesikhumba (i-dermis) lube luncane, futhi isikhumba siqale ukugoba nokushwabana. Nakuba singenakukuyeka ukuguga, kunezinto ezimbalwa esingazenza ukuze sigcine isikhumba sethu siphilile futhi sisebasha.
