Yintoni umthi weenwele? Makhe sijonge ngaphakathi!

Ngamafutshane, umngxuma weenwele luhlobo lwefayibha yeproteni eqinileyo epakishwe ngeeleya phezu komnye nomnye. Umngxuma weenwele esiwubonayo wenziwe ziinxalenye eziphambili ezininzi.

Iileya zeStrand yeenwele

Ukuba sinqumla umsonto weenwele, singabona iileya ezintathu eziphambili.

• Isikhumba:Le yilaphu engaphandle neyomeleleyo kakhulu yokukhusela yeshaft yeenwele. Yenziwe ziiseli ezigobeneyo phezu kwezinye njengeethayile ezincinci. Le "cuticle" ikhusela iindawo ezibuthathaka ngaphakathi kweshaft yeenwele ekonakalisweni. Nokuba iinwele zakho ziyakhazimla okanye azicacanga kuxhomekeke kwimpilo yale "cuticle".
• I-Cortex: I -cortex lulwaleko olungaphakathi kwe-cuticle olugubungela uninzi lwe-shaft yeenwele. Kukule nxalenye ye-shaft yeenwele apho uninzi lwe-melanin, olunoxanduva lokuqina nokuguquguquka kwe-shaft yeenwele, kunye nombala weenwele, lufakwa khona.
• IMedulla: Umaleko osembindini we-hair shaft, eyona maleko ingaphakathi, ubizwa ngokuba yi-medulla. Nangona kunjalo, le ndawo ibizwa ngokuba yi-medulla ayibonakali ngokucacileyo kuyo yonke i-hair shaft. Isenokungabonakali, ingakumbi kwi-hair shafts ezincinci kakhulu nezincinci. Oogqirha kunye noososayensi basaphanda umsebenzi wayo ngqo.

Umzi-mveliso weenwele: I-Follicle

Uboya ngabunye bukhula buvela kwisakhiwo esincinci esifana nengxowa eluswini, ngaphantsi nje komphezulu wesikhumba. Oku sikubiza ngokuba yi-'follicle'. Kanye njengokuba isityalo sikhula embizeni, iinwele zikhula ngaphakathi kweli 'follicle'. Emazantsi ale 'follicle' kukho inxalenye ekhethekileyo ebizwa ngokuba yi-'papilla' . Kulapho ukukhula kweenwele kwenzeka khona. Ingcambu yeenwele, oko kukuthi, inxalenye ethambileyo efana nebhalbhu ezantsi kweenwele, ingaphakathi kweli 'follicle'. Inxalenye ephuma kumphezulu wesikhumba kwaye siyibonayo ibizwa ngokuba yi-hair shaft .

Ii-oyile Glands nazo zidibene!

I-follicle nganye yeenwele iqhagamshelwe kwenye i-gland encinci. Oku kubizwa ngokuba yi-sebaceous gland . I-oyile ekhutshwa zezi gland (ebizwa ngokuba yi-sebum) iphuma kwi-hair shaft ize ithintele iinwele zethu kunye nolusu ukuba lungatshi. Le oyile yiyo enika iinwele zethu ukukhanya kwayo kwaye igcine ulusu lwethu luthambile.

Iinwele zikhula njani? Yinkqubo emangalisayo kakhulu le!

Ukukhula kwe-hair shaft yinkqubo entsonkothileyo kakhulu, kodwa emangalisayo. Uyakhumbula indawo ebizwa ngokuba yi-'Papilla' ezantsi kwe-'Follicle' esithethe ngayo ngaphambili? Kulapho iqala khona yonke into. I-'Papilla' ifumana ukondla kwayo kwimithambo yegazi engaphantsi kwayo. Ngokusebenzisa olu kondla, iiseli ezikwi-'Papilla' ziqala ukukhula ezintsha. Ezi seli zintsha zeenwele ziyakhula kancinci kancinci, emva koko ziyafa, kwaye ziqine. Le nkqubo yokuqina ibizwa ngokuba yi -'Keratinization'.I-Keratin yiproteni ephambili efumaneka kwizinto ezifana neenwele zethu kunye neenzipho. Ngoko ke, njengoko iiseli ezintsha ziqhubeka zenzeka ngaphantsi kwe-papilla, iiseli ezindala, ezifakwe i-keratin ziyanyuswa. Oku kutyhala nokutyhala ekugqibeleni kubangela ukuba umngxuma weenwele uphume kumphezulu wesikhumba. Kufana nomzi-mveliso owenza imveliso uze uyikhulule.

Ukukhula kweenwele akupheli. Xa iinwele ziphuma, kuvela i-follicle entsha yeenwele (nangona oku kunokutshintsha kwezinye iimeko zonyango, kodwa le yimeko eqhelekileyo).

Yenziwa njani umbala kunye nokwakheka kweenwele? Oku kukwanomdla kakhulu!

Azifani zonke iinwele zethu. Ezinye zineenwele ezimnyama, ezinye zineenwele ezimdaka, kwaye ezinye zineenwele ezibomvu. Ngokufanayo, ezinye zineenwele ezigudileyo nezithe tye. Ezinye zineenwele ezigobileyo okanye ezigobileyo. Makhe sijonge izizathu zale mahluko.

Isizathu Sombala Weenwele

Iinwele zifumana umbala wazo kwi-pigment ekhethekileyo ebizwa ngokuba yi -'Melanin' . Kukho iintlobo ezimbini eziphambili ze-'Melanin' kwiinwele zethu: 1. `Eumelanin` 2. `Pheomelanin` Umbala weenwele zakho umiselwa bubungakanani bezi ntlobo zimbini ze-'Melanin` kwiinwele zakho.

• Abantu abane- eumelanin eninzi baneenwele ezimnyama (ezimdaka okanye ezimnyama).

• Abantu abanamanqanaba aphantsi e -`Eumelanin` kunye ne-`Pheomelanin` baneenwele ezikhanyayo (iinwele ezimthubi) .

Usenokuba uqaphele ukuba iinwele zabantu abaninzi ziba ngwevu okanye zibe mhlophe njengoko bekhula. Isizathu soku kukuba njengoko sikhula, iifollicle zethu zeenwele azisakwazi ukuvelisa i-melanin ngokulula njengoko zazisenza xa sasisebancinci. Xa imveliso ye-melanin incipha, umngxuma weenwele ulahlekelwa ngumbala wawo, oko kuthetha ukuba ujika ube mhlophe.

Ubume beenwele

Uhlobo lweenwele, nokuba zithe tye, zigobile, ziqinile, okanye zincinci, lumiselwa yindlela ezimile ngayo iinwele.

• Kwakhona, nangona ezinye iifollicles zivelisa iinwele ezityebileyo, ezinye zivelisa iinwele ezibhityileyo.

Zonke ezi zinto zizinto esizizuz’ ilifa ngokwemfuza.
