Ngaba kufuneka sazi kakuhle umaleko ophakathi wolusu lwethu, i-dermis?

Ngaba wakha wazibuza ukuba ulusu lwakho lusebenza ngendlela emangalisayo kangakanani? Ulusu lwethu aluyonto nje yokwambathisa umzimba wethu. Lulungu oluntsonkothileyo nolubalulekileyo. Ulusu lwethu lwenziwe ngamaleya amathathu aphambili. Namhlanje siza kuthetha ngeyona laya ibalulekileyo kwezi, umaleko ophakathi. Siwubiza ngokuba yi-dermis . Ngamanye amaxesha ubizwa ngokuba yi-corium , eliligama lesiLatini elithetha "ulusu."

Yintoni idermis? Ngamafutshane...

Ngamafutshane, umaleko ophakathi wolusu lwakho yidermis. Umaleko ongaphezulu ubizwa ngokuba yi-epidermis, kwaye umaleko osezantsi ubizwa ngokuba yi-hypodermis. Ngoko ke idermis iphakathi komaleko ongaphezulu kunye nomaleko osezantsi.

Cinga ngayo njengesandwich. Isilayi esingaphezulu sesonka yi-epidermis, isilayi esisezantsi yi-hypodermis. Isithako esimnandi esiphakathi yi-dermis. Ngaphakathi kwesi dermis, kukho ezinye iileya ezimbini zazo. Masijonge naleyo.

Zithini iileya ezimbini kwidermis?

Ewe, le dermis ayilomaleko mnye. Kukho ezinye iindawo ezimbini ngaphakathi kwayo. Nazi:

1. I-Reticular Dermis - umaleko osezantsi

Le yeyona ndawo ityebileyo yedermis, phantsi kwayo. Ifana nesiseko sendlu. Kungaphakathi kwayo apho kukho izinto ezininzi ezibaluleke kakhulu kulusu lwethu.

• Imithambo yegazi: Le yiyo enika ulusu izondlo ezifunekayo.
• Ii-Glands: Izinto ezifana nee-sweat glands, ii-sebaceous glands (ezivelisa ioyile).
• Iifollicle zeenwele: Kulapho zikhula khona iinwele emzimbeni wethu.
• Iilymphatics: Ezinxulumene nenkqubo yomzimba yokuzikhusela.
• Iimithambo-luvo: Ezi zinika imvakalelo.
• Iiseli zamafutha.

Le dermis ye-reticular ijikelezwe luthungelwano lwe -elastin kunye neefayibha ze-collagen. Cinga ngale ndlela: i-elastin ifana nebhendi yerabha, kwaye i-collagen ifana nomsonto oqinileyo. Ezi zimbini zinika ulusu lwethu amandla kunye nokuguquguquka. Ezi zimbini zisivumela ukuba solule kwaye solule ulusu lwethu.

2. I-Papillary Dermis - Umaleko ophezulu

Olu lolona luhlu luncinci kancinci phezu kwedermis. Lutyebile kunedermis ye-reticular. Lukwanemisebenzi emininzi ebalulekileyo:

• Iifayibha zeCollagen.
• Iiseli zeFibroblast: Ezi ziiseli ezinceda ekwenzeni izinto ezifana ne-collagen.
• Iiseli zamafutha.
• Ii-Capillary loops: Zinceda ukondla i-epidermis.
• Imicu yemithambo-luvo.
• Ii-touch receptors (umz. ii-corpuscles zikaMeissner): zisinceda ukuba siqonde ukuchukumisa.
• Iiseli ezilwa neebhaktheriya (ii-phagocytes): Njengezikhuselo eluswini lwethu.

Le papillary dermis ifikelela kumaleko angaphantsi kwesikhumba sephepha. Ezi layer zimbini zidibene njengeminwe yezandla zethu zidibene . Yingakho kukho unxibelelwano oluqinileyo phakathi komaleko ongaphezulu kunye nomaleko ophakathi.

Ngoko ke yintoni umahluko phakathi kwe-dermis kunye ne-epidermis?

Ngoku ekubeni unembono encinci ngezi layer zimbini, masichaze ngakumbi.

• I-Epidermis: Le yilaphu engaphandle nebhityileyo yolusu lwethu. Ifana neempahla zethu. Igcina imizimba yethu imanzi, yenza iiseli ezintsha zolusu, kwaye isikhusela ekonakaleni kwangaphandle (njengokunqunyulwa, imikrwelo, kunye neentsholongwane). Kulapho i-melanin enika ulusu lwethu umbala wayo yenziwa khona.

• I-Dermis: Le yingqimba ephakathi, etyebileyo yolusu . Ityebile kakhulu kune-epidermis. Iqulethe i-collagen kunye ne-elastin, ezinika ulusu amandla alo, ubukhulu, kunye nolwakhiwo oluxhasayo.

Khawucinge nje, ukuba i-epidermis ifana nophahla lwendlu, i-dermis ziindonga kunye neensika ezibamba olo phahla kunye.

Izicubu ezidityanisiweyo, iziphelo zemithambo-luvo, ii-sweat glands, ii-oil glands, kunye nee-hair follicles eluswini lwethu zonke zifumaneka ngaphakathi kwe-dermis. Oku kuthetha ukuba uninzi "lwabasebenzi" besikhumba lufumaneka apha.

Zeziphi iinkonzo ezibonelelwa yidermis emizimbeni yethu?

Zonke iileya zolusu lwethu zisebenza kunye ukukhusela imizimba yethu. Phakathi kwazo, i-dermis inemisebenzi emininzi ekhethekileyo. Jonga:

• Ixhasa i-Epidermis: I-dermis inika inkxaso entle kumaleko ongaphezulu ngenxa yesakhiwo sayo esomeleleyo kunye nokuthamba kwayo. Kwakhona, imithambo yegazi kwi-dermis ithwala izondlo ezifunekayo kwi-epidermis.
• Isenza sikwazi ukuva iimvakalelo ezahlukeneyo: Iziphelo zemithambo-luvo kwidermis zezona zisivumela ukuba sive izinto ezinje ngoxinzelelo, iintlungu, ubushushu, ukubanda, kunye nokurhawuzelelwa . Cinga ngayo, ukulunywa yingcongconi kuyabuhlungu, iqhekeza lomkhenkce livakala libanda - zonke ezi zimpawu zivela kwidermis.
• Ukubila kuyaveliswa: Ngaba uyabila xa uziva ushushu okanye uxinezelekile? Loo ukubila kuveliswa zii-sweat glands ezikwi-dermis. Xa sibila,Ubushushu bomzimba buyalawulwa (thermoregulation) .
• Igcina ulusu lufumile: I-dermis inee -sebaceous glands . Ezi zikhupha into enamafutha ebizwa ngokuba yi-sebum . Le sebum yiyo egcina ulusu lwethu neenwele zethu zifumile kwaye zikhazimla, ngaphandle kokuzomisa.
• Iinwele ziveliswa: Iinwele ziveliswa ziifollicle zeenwele kwidermis, phantse kuyo yonke indawo emzimbeni ngaphandle kwezandla zethu kunye neenyawo zethu.

I-dermis inceda njani amanye amalungu omzimba?

Kunye nezinye iileya zolusu, i-dermis ikhusela inkqubo yethu yamathambo, amalungu angaphakathi, izihlunu, kunye nezicubu kumonakalo wangaphandle, njengeqokobhe elikhuselayo.

Iphi idermis? Ingakanani? Yenziwe ngantoni?

Njengoko besitshilo ngaphambili, i-dermis lulwaleko oluphakathi kwesikhumba, oluphakathi kwe-epidermis kunye ne-hypodermis.

Ubukhulu bale nto buyahluka ngokweendawo emzimbeni. Umzekelo, incinci kakhulu kwiinkophe, malunga ne-0.6 yeemilimitha . Kodwa ngasemva, ingaba malunga ne-4 yeemilimitha ubukhulu .

I-dermis yenziwe ikakhulu zizicwili ezinemithambo yegazi emininzi. Ikwaqulathe:

• I-Collagen
• I-Elastin
• Ulwelo olucacileyo, olufana nejeli (into esemhlabeni) oluzalisa izithuba eziphakathi kweeseli kunye nemicu.
• Iintlobo ngeentlobo ze-glands ezifana nee-sweat glands kunye ne-sebaceous glands.
• Iifollicle zeenwele .
