Ubume kweenwele

Ukuqwalasela isakhiwo nonwele lomntu, kukho ezintathu iintlobo uboya :

- imibungu (kwangaphambi);

- vellus;

- intermedia (eziguqukayo);

- ezinoboya kunye elide (terminal).

Vellus kunye lwegciwane akukho mbala. Bona abunjwe nokumithwa. Ngaphambi kokuba ukuzalwa inguqu kuvela iinwele ulwehlo. Ebudeni beminyaka emithathu yokuqala omzimba womntwana alekwe ukukhanya, iinwele vellus ethambileyo. Xa uqeqeshelwa ukuba ngumntu omdala , baba esinzima, iqala ukukhula kungena nasemiphakathweni, amakhwapha, amadoda - umzimba nobuso. Uboya ezinoboya zikhula phezu iinkophe, iintshiyi, womsindo. Ukhakhayi yiyo yonke iintlobo.

Enjengesakhiwo follicle kweenwele kuquka kunye ngentonga. Iingcambu kusuka izihlunu adipose ongama ngokusebenzisa dermis ukuya sangaphandle. Ngelo isanda lokukhula kweenwele oko ibekwe kwi dermis. Ingcambu iqulethe bulb eqinileyo, ibekwe ngaphakathi follicle.

Isakhiwo ikuvumela ukuba zikhule iinwele ngokuqhubekekayo senziwa similise ngekeratini kunye ngokuthe lihamba lwangaphandle ifomu ntambo. Izinga lokukhula ngosuku malunga ukusuka 0.2 ukuya 0.4 mm ngosuku.

Isakhiwo iquka papilla iinwele dermal apho ngamandla avela kwegazi.

Follicle kunye ibhalbhu singaphulukana ngenxa ifuthe emzimbeni, kwaye ifuthe components zinetyhefu, leyo kufika engcanjini ngaphandle kunye imfihlelo, eveliswe amadlala sebaceous.

Liphuma ngaphezu engundoqo esikhumbeni. Ubume luthe unwele esibethweni inxalenye simelwe ngeengcamba ezintathu.

I engaphandle (Ulobuza) inikezela imisebenzi yokhuseleko. Ubume iinwele kulo maleko ubhityileyo iiseli linikwa kwi ngohlobo kukubola, idlulela omnye. Xa nesikali ofanelekileyo ezichanekileyo close, iinwele ethambileyo, silky. Ukuba kukho umonakalo Ulobuza (zeekhemikali okanye ngokwasemzimbeni), bona (Kwaneenwele) aqalile mazingabhidaniswa, zaqina, wolahlekelwa zisakhazimla.

Umaleko eliphakathi ebizwa ezinezikhondo. It iqulathe imicu ngekeratini. Lo maleko kucingelwa ukuba isakhiwo iinwele esisiseko, ekubeni kukho wenza iinkqubo yemichiza (ngenxa wendiza, ukudaya).

Umaleko yesithathu ityhubhu umngxuma. Akukho linegalelo naziphi na iinkqubo elo, oko angekhoyo ngabantu abaninzi.

Umjikelo epheleleyo wokusungula iinwele epheleleyo kubandakanya nezigaba ezithathu: anagen, telogen, catagen.

Ngelo kwinqanaba lokuqala, iyantlukwano cell esebenzayo - inkqubo mitosis. melanin yoko, iiseli ezintsha akhiwa kwizikhondo zeenwele yenziwe (kombala). izakhi ophelileyo, kuquka ngqo isakhiwo, inikeza umbala. Inqanaba lokukhula Active ithatha ukusuka kwiminyaka emibini ukuya esixhenxe.

Kwisigaba esilandelayo (isigaba catagen) uyayeka iyantlukwano iiseli kunye nokukhula iinwele. Kombala ngaloo ndlela igqibezela lasungulwa. Kweli nqanaba follicle iqala ukunciphisa, itswele - ukuba bafudukele sangaphandle. Esi sigaba ithatha iiveki eziliqela.

Yinkalo yokugqibela ukubunjwa ithatha iinyanga ezintathu. Kwisigaba telogen yokukhula iinwele zokumisa ngokupheleleyo, lo follicle ingena kwimo yokuphumla. Kwesi sigaba, uboya zingalula kususwe okanye sifuba nje ukuwa. Xa imvula ukusunduza kwaye ukuyilwa kwento ngomsonto entsha. Ukuqala Ukukhula esebenzayo kwenzeka kwi follicle efanayo. Ukusuka buyakwazi malunga namashumi amabini ukuya kwamathathu iinwele ezintsha.

Zonke izigaba ezichazwe ngasentla kwenzeka mihla le. Xa iinwele abanye abantu bakaThixo bazalwa, sikhulele, ziphume ngokukhawuleza kunezinye. I-avareji yenani zoboya phezu kwentloko yomntu lumalunga ne-100 lamawaka. Ngelo xesha malunga ne-10% kuzo zikwimeko ukuphumla.

Iinwele iqulethe ubukhulu becala ngekeratini. Kwakhona ngoku yaye amanye amanzi, amacandelo izimbiwa, ndikho apha emzimbeni.

Ukugcina iinwele kuphela ishampu ezizodwa ngokwaneleyo ukusebenzisa zikwimeko esempilweni, iimaski okanye balms. Kuba nokudaleka efunekayo zizityebi ngakwicala leeprothini, iivithamini, ayodini, intsimbi, kunye namanye amacandelo ukutya.
