Layered mamiriro: akaturikidzana ganda

layered nemamiriro ganda - 3 akaturikidzana kuita zvakasiyana mabasa. Anokosha aya ndiwo dermal ane ropa midziyo, receptors uye tsandanyama. Also riri dermis bvudzi. Uye "tateguru" yavo, uyewo zvipikiri, ndiyo Epiderme e. Chii? Izvi rukoko horny iri chete pamusoro dermis uye kunokosha rwokudzivirira basa, kwete chete pazvinhu pazviri, asiwo yose muviri. Little zvakadzika dermis hazvinyanyi kukosha rukoko ganda - zvinyama, apo mafuta rinoungana mu adipocytes.

Gobvu rukoko ndiyo basal izvo wose ine masero anokwanisa kuparadzanise. Nokuda kwavari pane kudzorerwa zvaparadzwa masero uye replenishment kurasika horny pachiyero. Pakukora ari basal rukoko melanocytes riri benyu kuunganidza fuma dema ruvara (rwe-melanin) zvinodiwa ultraviolet pakudzivirira ganda.

Prickly rukoko yaiva pamusoro basal uye kuvakwa muchimiro mitsara 3-8 kurarama nechekare masero vasingakwanisi kugovera. Vari machira mumwe kuburikidza cytoplasmic miganhu yokupa simba zvemaziso dzematehwe. Munzvimbo ganda pasi Kufurirwa nevamwe kuitika kakawanda, nhamba akaturikidzana spiny masero kunowedzera kusvika 8-10 zvidimbu. Munzvimbo idzi hapana ziya omumuviri uye bvudzi: tsoka uye ruoko. With kakawanda kukuvara zvimwe zvikamu akaturikidzana pakati Epiderme e uyewo thickened kuti vaumbe callus.

Pakarepo pamusoro spinous wokutanga ndiye granular, iro rine hafu akafa epidermal masero. organelles dzavo vanorasikirwa kugona kubereka simba, asi kuunganidza inokosha mari tonofibrils. Granular rukoko anoumbwa muchitokisi akaturikidzana 1-2 chete akatarisa akaererana ganda pamusoro.

Brilliant rukoko akadana masero zvachose kuine organelles. chinangwa chavo - the zvokuimba pakudzivirira ganda uye zvishoma nezvishoma kutsakatika, kudzikisirana kuti stratum corneum.

Izvi zvinoreva kuti cuticle kunodzivirira zvakakanganisika kwemvura nemvura, uye ruvara masero - kubva ultraviolet nemwaranzi. Izvi zvose akabvumira murume kuchinja mamiriro ezvinhu kuti kuitika munyika dzose munyika. Pashure pezvose, ganda akabvumira kukura nhengo iyo murume kumhuka, kubva mumvura uye kukunda nyika.

The chikuru zviri Epiderme e

akaturikidzana All ganda phylogenetically rakavapo nokuda kupa mamwe mabasa. The Epiderme e ndiyo dermis akagadzirirwa kudzivirira pamusoro zvemaziso, panyama uye makemikari nemigumisiro. It unodiwa kushomeka kurasikirwa Urume zvinogona sasana kubva ayo panyika chete pashure secretion kuti ziya mumasero. Chimwe nzira nokuti vasiri mvura leakage kubva mumuviri kuburikidza ganda iripo.

Kana isu funga Epiderme e kubva zvizorwa nemaonero, zviri pachena ndivo dzinotevera. Izvi ganda rukoko irege kuva wrinkles uye mavanga, hakuna midziyo ropa. Zvinonzi dzinofambiswa nokuda diffusion pakati zvinhu kubva ropa midziyo dermis ganda. Naizvozvo matambudziko aro zvizorwa chete ndedzinotevera: hyperkeratosis (thickened Epiderme e akaturikidzana) uye ganda peeling. Chinorwisa izvi zviitiko, uye psoriasis, uye kurapwa kunoda kushanda zvizoro.
