Mmene Kuphulika kwa Nyamakazi Kumayambira
Mphuno yamtunduwu ndi matenda aakulu a zozizira za sebaceous . Ngakhale nthawi zina zimawoneka kuti ziphuphu zikuwonekera usiku womwewo, chitukuko cha kutuluka kwa ziphuphu ndizowonjezereka zomwe zimayambira pamaseli a ma selo. Ziphuphu zonse zimayamba ngati kupukuta kwa tsitsi , kapena pore. Kumvetsetsa chifukwa chake kutsekeka kumayambira ndi momwe pimple ikukula potsirizira pake idzakuthandizani kuti muchepetse mankhwala anu.
The Epidermis
Mbali yakunja ya khungu, gawo lomwe mumaliwona tsiku lililonse, limatchedwa epidermis. Epidermis ili ndi zigawo zisanu. Chimake chozama kwambiri cha epidermis ndicho chidziwitso germinativum. Ilo limapangidwa ndi selo limodzi la maselo. Kugawidwa kwa magulu, kapena mitosis, kumachitika mu stratum germinativum.
Maselo atsopano amayamba ulendo wawo kudutsa pa epidermis kupita khungu. Choyamba, iwo amawongolera kupyolera mu chingwe chotchedwa mucosum, ndiye chingwe cha spinosum. Zigawo zitatu (stratum germinativum, mucosum, ndi spinosum) pamodzi zimatchedwa basal wosanjikiza.
Pamene maselo a khungu akupita patsogolo, amafika ku stranuum granulosum. M'kati mwake, maselo amayamba kufa ndi kuumitsa, kuwapatsa mawonekedwe a granular. Pomwe maselo akufika ku strneum corneum, afa.
Chida cha corneum chimapangidwa ndi maselo a khungu amene ali ndi mafupa, omwe amapitirizabe kugwedezeka.
Ntchitoyi imatchedwa kuti dequamation . Zimatengera pafupifupi masiku 28, kuchokera pa selo kubadwa mpaka kusuntha, kuti zichitike.
Chiphunzitso
Dermis ndi gawo lakuya, kapena mkati, la khungu lanu ndipo limapangidwa ndi minofu yolimba. Dermis imadyetsa komanso imapereka magazi kwa epidermis. Chimodzimodzinso chimapangitsa khungu kukhala lokhazikika.
Dermis ndi wochuluka kwambiri kuposa epidermis koma ali ndi zigawo ziwiri zosiyana: mapepala ophimba ndi osanjikiza.
M'mimbayi, mudzapeza zitsulo zamagazi ndi zamagulu, mitsempha, mitsempha yachiwiri ya mitsempha (minofu yomwe imapangitsa tsitsi lanu kuima pamapeto), glands la thukuta (sweat), zofiira (mafuta), ndi tsitsi la tsitsi. Imakhala mkati mwa ubweya wa tsitsi ndi zofiira zomwe zimayamba.
Tsitsi la Tsitsi
Kupaka tsitsi kumakhala kochepa, kotsegula ngati khungu pamphuno pomwe tsitsi ndi sebum zimagwira khungu. Mphunoyi imakhala ndi kutsegula kwa pore, mizu ya tsitsi ndi babu, njira zamadzimadzi, ndi zotsekemera. Ngakhale kuti ili mkati mwa nthendayi, epidermis imayendetsa mkati mwa nsalu ya tsitsi.
Muzomwe zimagwiritsidwa ntchito, maselo osakanikirana amachititsa mafuta, kapena sebum, kukhala pore. Kawirikawiri, maselo a sebum ndi akufa amachotsedwa kuchokera ku chimbudzi cha corneum kutuluka pakhungu pamtunda. Kwa iwo okhala ndi ziphuphu, komabe, ndondomekoyi imapita mofulumira.
Khungu lochepetsedwa ndi mavalasi, sebum ndi maselo a khungu akufa mosavuta amalowa mumsangamsanga. Kusungunuka kwa zinyalala zam'manja ndi zinthu zowonongeka zimapanga pulagi yolimba yomwe imalepheretsa kutsegula kwa pore. Kulepheretsa uku kumatchedwa comedo .
Zikuwoneka ngati zopanda moto kapena mitu yakuda pamphuno.
Propionibacteria Acnes
Propionibacterium acnes (P. acnes) ndi bakiteriya omwe amachititsa kuti ziphuphu zisawonongeke. P. acnes ndi anthu omwe amakhalapo nthawi zonse pamutu wa tsitsi. Kawirikawiri, iwo alibe vuto. Komabe, khungu lopangidwa ndi chifuwa chachikulu cha P. acnes chimakula.
Pamene comedo imatsegula kutseguka kwa pore, imapanga chilengedwe cha anaerobic kapena kusowa kwa mpweya mu follicle. Malo a anaerobic, pamodzi ndi sebum yambiri mkati mwa pore, amapanga malo abwino komwe P. acnes mabakiteriya angapindule.
Pamene follicle imadzazidwa ndi sebum, maselo akufa, ndi mabakiteriya, imayamba kuphulika. Mpanda wamakono umagawanika ndikudumpha m'madzi. Maselo oyera amathamangira kukamenyana ndi mabakiteriya. Kufiira ndi kutupa zimachitika, ndipo pus imapangidwa. Pimple yakhazikitsidwa tsopano.
Ngati kupasuka kwa khoma la follicle kumachitika pafupi, pamwamba pake kawirikawiri ndi wamng'ono ndipo amachiza mwamsanga. Ndi pamene mphuno imapezeka mkatikati mwa nthendayi kuti zilonda zazikulu, monga mitsempha ndi mphutsi , zimakula
