Ulusu Analyzer: isakhiwo, umsebenzi kunye nexabiso. isikhumba nokwakheka

Nge ngqikelelo njengoko "analyzer isikhumba" ezinjalo, asingabo bonke abantu abaye bajamelana. Uninzi baqhele ukubiza i elifutshane lixhaphakile eli gama ngakumbi,. Oko kukuthi, isikhumba. Kodwa, enyanisweni, zombini ingqiqo ibhekisela ilungu enzima, nto leyo ke isigqubuthelo wethu engaphandle. Omnye ezimbalwa emzimbeni wethu, leyo ngokulula iphathwayo ngalo naliphi na ixesha. indawo abadala ulusu lomntu malunga 1.5 - 2.3 square metres. A ubunzima kunye sangaphandle (zangaphandle ibekwe kumphezulu nzulu) yi 16-17% ngokobunzima. Noko ke, konke oku kufuneka ndithi kuni ngakumbi.

sangaphandle

Kuqala kwinto zonke, ethetha malunga analyzer eluswini, kuyimfuneko ukuba kuchaphazela sangaphandle ingqalelo. Nguye umaleko wethu angaphandle. Kodwa ke ukuba ukuthetha ngolwimi olulula. Enyanisweni, sangaphandle - epithelium multilayered lithathwe. Le isikhumba elingqingqwa, okungabandakanywanga ngeenwele, oko kuquka kangangoko 5 zikhabane. Ngamnye kubo ngaphezu dermis. Kwaye bonke yokwenza umsebenzi umqobo.

An caveat ebalulekileyo: sangaphandle kuba yinqobo njalo ukubuyekeza. Kwaye oku edibene nkcukacha yokufuduka nenguqu ekuthiwa keratinocytes. Le - iiseli kwithishyu epithelial. zixhobo zawo thaca protein ngekeratini. Ngaphezu koko, kubalulekile ukuba wazi ukuba sangaphandle iqulathe amacandelo athile yamajoni omzimba.

Isakhiwo sangaphandle

Anatomy of isikhumba sinzima kakhulu. sangaphandle (enye yeencindi) kuphela iquka maleko ezintlanu ezahlukeneyo. Okokuqala - Basal. Okanye, njengokuba kubhaliwe ngokuba, intshule. Eyona nto ibaluleke ngokwenene ukwazi malunga umaleko carcinomas - kukuba luqulethe ebizwa ngokuba yi-melanosomes. Oku granules melanin, leyo kusikhusela impembelelo evela UV eyingozi kuthi.

Umaleko yesibini ekuthiwa nengwane. Kwakhona iquka ubunzima iseli, kodwa "izitena" kakhulu ezibalulekileyo ingqalelo izixhobo tonofibrillyarny. Yeyona ukhuselo engundoqo iiseli ukusuka umonakalo.

Kukho umaleko granular. 1-2 sakhiwa uthotho iiseli evuthelweyo. Oku kuhlelwe kule ezikroziswayo filaggrin keratolinin (iiproteni zezakhiwo). Kwaye ikhuthaza keratinization le epithelium. Oku, koko, yinkqubo kakhulu inzima, apho isikhumba horny amagama ufumana okubuyela kwimo yakhe semvelo kunye namandla.

Umaleko yesine yaziwa tsiklovidny (okanye shiny). Xa zaso akukho organelles okanye nuclei. Kwaye kukhangeleka ngathi ngomvumbo okuqaqambileyo ube bomvu. Lo maleko enhle kwi ngeentende namasundu.

Ke yokugqibela - Horny. Le eluswini, nto zokhuselo. iiseli abahlala kuyo musa. Yintoni akumangalisi, kuba ukhandwa keratinocytes abafileyo. Okanye, njengoko ibizwa, izikali horny. Ubungakanani lo maleko na elingqingqwa, kuxhomekeke umthwalo bafakela esikhumbeni.

dermis

Oku - into elandelayo ekufuneka iqwalaselisisiwe ingqalelo, ukuthetha malunga analyzer esikhumbeni. Ngenxa yokuba dermis na isikhumba ngqo. Kwaye ukuba oko ngolwimi lwezenzululwazi - inxalenye nokuqina kwayo.

Le dermis amanga ngezantsi sangaphandle. Kodwa ngokungqalileyo, kodwa ezahlulwe inwebu Uhlobo Lokuqala. Zibonisa intabalala emithanjeni neefayibha, ngoko dermal kunikwa inkxaso kunye nemisebenzi trophic. Yena, efana sangaphandle yenziwa kwiiseli ezininzi. Noko ke, ngenxa yokuba inani elincinane - kukho amathathu kuphela.

Izinto eziyinxalenye yale dermis

Anatomy of isikhumba inzima kakhulu, kodwa unako ukuqonda oko. Kuphela abathathu umaleko, kwaye yokuqala ufanelwe ingqalelo - papillary. Kutheni bakubiza? Ngenxa yokuba lo maleko wokuqala iqulathe i "papillae 'engena sangaphandle. Oku kuquka inqwaba "amacandelo". Oku basophils zomzimba, macrophage kunye nezinye iiseli ezininzi igalelo ekuphunyezweni zikhusela lwamajoni ethu omzimba.

Umaleko yesibini ubizwa ngokuba enemingxuma. Yenza i izihlunu ashinyeneyo ezinezikhondo nokuqina. Ngokwenene, oku - kwindawo engundoqo ye dermis. Kungenxa kule nwebu enemingxuma iqulethe imicu collagen inamandla igalelo ukuphumeza umsebenzi inkxaso.

Umaleko yokugqibela ibizwa ngokuba sangaphandle. Wada wabiza ezinamanqatha inyama ongama. Sikhoyo ngqo phantsi dermis. Kwaye, njengoko unako iqondwe ukusuka igama, lisekwa okunamafutha kwithishyu. Kungenxa phantsi kwesikhumba luyakha amanzi kunye nezondlo. Ukongeza, le hypodermis kunceda thermoregulation.

Umsebenzi: ukhuseleko zokuhlanjululwa

Ngoko ke, yintoni na analyzer isikhumba ecacileyo. Ngoku ke kunokwenzeka ukuba kunikezelwe wenze imisebenzi yawo.

Lokuqala - i zokhuselo. Njengoko sele kukhankanyiwe, sangaphandle kwimpembelelo ngqo lokusingqongileyo ukhusela luvo, tissue, kunye neempahla. Isikhumba iqulethe namadlala sebaceous. umyalelo lwabo of 300 000. Kwaye ngexesha nyanga kuvelisa umlinganiselo 500-800 grams okunamafutha. It lubricates phezu eluswini, ukukhusela nto leyo ukusuka zonyango ezahlukeneyo.

Umsebenzi wesibini - ukucocwa. Ulusu badla cell xhopho. Ngaloo ndlela ekhulula umzimba ephilayo ukuba nemiphumela emibi izinto ezingena ngaphakathi ngamayeza okanye nokudla. Okubangel 'umdla kukuba, isikhumba malunga 2 million namadlala ukubila.

Ummiselo, esidla nokuphefumla

Oku - Kwakhona imisebenzi analyzer yesikhumba ngokwesiqhelo ilungu engundoqo.

Ke ummiselo. igazi isikhumba xa lobushushu ngaphandle kukuba ngaphantsi oko eziziimpawu umzimba. It has nomkhwezeli kwimeko eyahlukileyo. Ukuba iqondo lobushushu okukufutshane iphezulu kakhulu, izihlunu cutaneous bekhululekile, ukuze iimpahla uvuleke kunye nokusebenza ubushushu linyuke yi ngumzimba. Blood budget nayo olukhawulezileyo. Ngenxa yoko - ukubila ngokugqithiseleyo.

Ukwenza umsebenzi amandla kwakhona ukuba iindawo ezithile analyzer yesikhumba. Kungenxa ikhava kwethu ukungena kuwo umzimba, izilwanyana kunye nemifuno amafutha. Solutions nezithambiso sebenzi ngenxa ubume babo ethile. Yiloo nto ezi arhente izithambiso badla ngokuba "izondlo".

umsebenzi yokuphefumla, isimiso, luphawulwa ezineempawu ezifanayo. Ngenxa kubume aneentunja le nwebu ngesikhumba yabelwa 2% carbon dioxide. Ngokuqinisekileyo ukwazi oko akubantwini bonke ukuba kwiiyure ezingama-24 ibonisa lethu malunga 800 grams umphunga wamanzi!

uxhulumaniso zobuchopho

Ngaphezu kwaba iqashiso wathi ngoko na isikhumba yabantu. Isakhiwo kunye nemisebenzi yayo umdla ethile. Kwaye umntu kodwa kuchaphazela ingqalelo isihloko luvo, leyo "iqokobhe" wethu axhotyiswe kaninzi kunye.

Ukuze wayibeka ngolwimi efikelelekayo, isikhumba - oku yintsimi enkulu, oluphahlwe receptor. Kokuba njalo, njalo, bayaqonda nokushukunyiswa yendalo eyahlukileyo evela ngaphakathi nangaphandle.

luvo kunye nokuvalwa (zombini zicaciswa kakuhle kwaye free) - le nto Okuninzi kuquka nesikhumba somntu. Ulwakhiwo kunye nemisebenzi yazo ethile. luvo akhiwe sangaphandle kunye dermis. Ezi hypodermis ukuba phantse apho. Kuyo ingangena kuphela zemithi luvo bokwakha plexus apho, ukusuka apho imicu kunabela dermis. Ukusuka apho - ukuya zoboya, izihlunu, imithambo yegazi kunye namadlala nokubila.

Le kwalapho amagama abo. Umzekelo, ngenxa neeflaski Krause kwesikhumba uziva ebandayo. A corpuscles Meissner igalelo kwimbono wetatshi. Ngenxa Ruffini corpuscles siziva kufudumele. Uluhlu kungaba elide. Kodwa eyona nto inomdla kakhulu kukuba kwenye sentimitha square zezintsu akhawunti malunga 200 iintlungu, ubushushu 2, 12 no-20 ka receptors abandayo oyivileyo.

igazi

Ngokwendalo, isakhiwo analyzer isikhumba iimpawu zaso, ngenxa apho nokuhamba kwegazi.

Ngoko, kwi hypodermis, ukongeza luvo kunye neziphelo sizizitya ezinkulu. Kukho i umthambo. Bona baphuma ukusuka kuthungelwano esimbaxa ekuthiwa, ibekwe ngasentla nje ifascia. Ndithetha ngabo ekuqaleni.

Ukusuka apho inethiwekhi esimbaxa, efikelela ngakumbi - in nasekudeni esibekwa reticular. Yaye ukusuka apho - ngqo ukuya papillary.

Kubalulekile ukwazi ukuba imaleko ulusu kuphela emithanjeni kunye venules, kunye arterioles, kwaye ngaphezulu. Ngoobani abachaphazeleka ngqo kulo ummiselo bokuxhathisa systemic ezinemigca (total peripheral ukuxhathisa nemithambo). ithoni Arteriolar kubaluleke kakhulu. Emva kuxhomekeke ukuxhathisa peripheral, nto leyo ebonisa uxinzelelo lwegazi kulo. Nalu uphawu le analyzer yesikhumba. Noko ke, akumangalisi. Ngapha koko, sithetha nje, eyodwa yonke, apho ngokupheleleyo yonke into ezihambelanayo.

kuvelana

Lo mxholo Kananjalo kubalulekile ukuba siqaphele ingqalelo. Kukho ikho into uvakalelo ulusu-kwezihlunu. imvelaphi yayo icacile. Ngapha koko, ngokufuthi kwi izihlunu kuchaphazela ezichukumisayo ngaphambili nolusu. Ngokomzekelo, le massage efanayo.

Ke isikhumba uvakalelo okhethekileyo. It iqulathe analyzers ezahlukeneyo. Isivamvo wetatshi, umzekelo - yimvakalelo entsonkothileyo obuvela iimvakalelo zezifundo. njengokungathi lafaka kudlala indima ebalulekileyo apha. Analyzers, ekwazi kwengcinezelo kunye kwebala, sinike ulwazi malunga loxinano lwento, ukumila kwayo, ubushushu, imeko, ubungakanani, kunye nangaphezulu. Ingakumbi receptors ezininzi bakwezolimo lokufumana. Kuxhomekeke kubo uqala i "indlela" libonisa ulwazi idluliselwe ebuchotsheni.

kweemilo

Kuyinto yeentlobo ezimbini. Eyokuqala kuthiwa nokomzimba. Yinkqubo eqhelekileyo, zendalo esibandakanya cell yokuvuselela. ukwenzeka kwayo kuxhomekeka ukutya, impilo ngokwasemzimbeni kunye nezifo zabantu. Oku, kuchaphazela ukuvela kunye nesikhumba obutsha.

A ngokutsha reparative ithetha inshorensi ukubuyiselwa emva umonakalo. Emva kotyando, umzekelo. Le nkqubo inika umdla gqitha. Isigaba sokuqala komtshiso oko kwenzeka - eyeka nokopha, ukudumba kwenzeka, sikuxinile luvo eyethisa. Emva koko, ukwanda iqala. Inxeba izele emithanjeni kunye zomzimba nokuqina - ngaloo collagen. Inqanaba lokugqibela kubandakanya ukuyilwa kwesiva. Oku kugqiba inkqubo yokuzalisa indawo bengaphumelelanga epithelial kwithishyu.

Ezinye iimpawu ingaveliselwa ngonyaka. Kwaye ke ulusu luphawulwa ngokutsha, ngaphandle, azafunyanelwa ndawo umonakalo musa ukudlula. Ngenxa yokuba kuye kufuneka siphathwe ngenkathalo.

anika umdla

Kufuneka ukugqiba ibali oko kukuthi uvakalelo eluswini-kwezihlunu (isakhiwo analyzer kunye umsebenzi wayo, nathi reviewed). Eneneni, ezinye iinyani ezinika umdla, nokuba nabani na omnye kubo kuyaphawuleka:

• Kunzima ukucinga yonke kumphezulu yesikhumba sethu malunga nezigidi ezintlanu boya!
• Xa abadala kwesikhumba kwabantu ngama-60% iqulathe ukufuma. Abantwana - up to 90% (kodwa oku ke ubuninzi).
• Per square isentimitha yesikhumba iwela 100 ngoko.
• Kwi-avareji cover ifikelela 1-2 omise ubukhulu.
• Yeyona eluswini rough kwi ezintendeni. Uninzi angamarhoqorhoqo, neselubala - phezu iinkophe.
• Kubo bonke ubomi bakhe, malunga ne-18 eekhilogram yesikhumba nzima ithathwa indawo entsha.

Kaloku, wena na onokumxelela ezininzi izinto ezinomdla kakhulu malunga inshorensi wethu, isakhiwo sayo kunye neempawu ezithile. Kodwa ke komzimba ezisisiseko izibonelelo ezidweliswe ngasentla, kwaye luncedo ukuba ukukhumbula bonke abantu, kuba isihloko siphathelele sonke ngqo.
