Epidermis - He aha ka mea? Ka 'ole o ka epidermis

Skin, e like me na mea he nui dermatologists, o ka luna 'kanaka hui,. Ka mau papa, a me kaʻano o nā hana, hearty pukapuka o na moku koko a me ka pūʻulu o nā aʻalolo receptors hoolako ia nui i loko o ka 'ohana ka palekana o kekahi kanaka, mai? Aneie aʻe. A, o ka ili Radio i ke kūlana communicative, me ka hiki e loaa tactile ike mai ke waho ao nei. E ka luna, ahu iho o na epidermis mea nui wale me he me mechanical ke'ākeʻakeʻa mai, kona waiwai ka nui loa.

General ano o na epidermis

Ahu iho la ka mahele ana, kaʻoihana, e make ana a me kona make koke ana keena o ka epidermis. He aha ka mea? Kēia holoʻokoʻa lole i mea mau papa i keena loko mai o ka ia kumu, akā, hoonohonoho ma kekahi mau pae ke kaumaha ma muli o ka degere o ka maturation. Ke epidermis o ka mua ke'ākeʻakeʻa mai paʻaʻalo ma kekahi palena papaha pilikia no ke kino o ke kaiapuni ololi.

Pona paʻa 'ole: papa o ka ili

pona paʻa 'ole o kaʻili - 3 papa ae hana i kekahi mau hana. Ka loa nui o kēia mau mea i ka dermal ka koko moku, receptors a me nāʻiʻo. ¶ A aia ma ka dermis lauoho. A me kā lākou mau "kupuna", like hoʻi me kui, o ka epidermis. He aha ka mea? Kēia horny, ahu iho ke aupuni 'pono ma luna o ka dermis a Radio he kūlana aiiay,ʻaʻole wale nō i ana ia ia, akā, i ka mea a pau meaola. Littleʻoi dermis Ua emi nui, ahu iho o ka ili -'aʻaʻa, kahi momona accumulates ma adipocytes.

Pona paʻa 'ole o na epidermis

Ka hohonu, ahu iho o ka basal a loa iloko ona i kakauia na aeee hiki o ka māheleʻana. Ma muli o ia ia ma laila mea he hoihoi hou ia ana o ka poino keena a me replenishment o nalowale horny unahi. Ka mānoanoa o ka basal, ahu iho melanocytes ke aupuni 'hookahi loaa substanceʻeleʻele pigment (melanin) koi' ia no ka ultraviolet palekana o ka ili.

Prickly, ahu iho aia ma luna o ka basal, a kūkulu i loko o ka palapala o nā lālani 3-8 o ka hikiʻole, e puunaue ola aeee kāinoa mua. Ka mea, i hui i kekahi i kekahi ma cytoplasmic protrusions e hai aku me mechanical ikaika o ka ili. I mau mea o ka ili malalo i mawaho ololi ana pinepine, i ka helu o ka papa spiny keena, piʻi pū i 8-10 apana. Ma kēia wahi,ʻaʻole nō he hou glands a me ka lauoho: ka wawae a me ka lima. Me ka pinepine poino nā haʻawina o nā papa o nā epidermis pūʻia naʻe i ka hana i ka callus.

Koke ma luna o ka spinous, ahu iho ka granular, a iloko ona i kakauia i ka hapalua make epidermal keena. Lākou mau organelles lilo aku hiki i ka paka ikehu, akā, loaa he nui nui o tonofibrils. Granular, ahu iho haku o wale 1-2 aeea papa aʻo i kaʻoihana ia laua i ka ili ili honua.

Maikaʻi loa, ahu iho kapa aeee loa devoid o organelles. I ko lakou manao - ka me mechanical palekana o ka ili a me ka holo ia'na, hoʻololi iho i ka stratum corneum. I ka la mahope Ua superficial. He he huihui 'ana o ka make scaly keena, a nō ka'ākeʻakeʻa mai nui i ka pathogenic ololi.

Hana o ka epidermal keena

O ka papa kuhikuhi hana o na epidermis o ka hanaia'na o ÿole mechanical, physical, liluwelo a me ka Nine Inch nā pale kaʻa, delimiting mai ka Loaʻaʻia a me maoli pathogens ka maloko kaiapuni. Akā, i ka i nā mea a pau a Ma¯noa i hoʻokaniʻia e nā epidermis. He aha ka mea, a pehea e like wehewehe?

• Mua, o ka ili honua, ahu iho delimits ka papa o ke kino, a me ka waho ao nei, e hoomalu aku i ke kino, a no ka pale kulu o ka nui 'ona a me eiiiiiaiou.
• Ka lua, ua pono ka mea i malama i ka epidermis e ku e ionizing corpuscular a me ka nalu pāhawewe o haʻahaʻa mana, a me i ke kino huli kela la i keia.
• Ekolu, na epidermis o ka ili - he maikai Nine Inch ke'ākeʻakeʻa mai i ka pale aku anal a me ka omo o hydrophilic waiwai. A me ka lipophilic (momona-wailana) ka mea, e pono assimilated.
• A me ka hope ma ka papa inoa, akā,ʻaʻohe emi nui kuleana pili i - liluwelo hoomalu. Aia He He uuku loa nui o koʻohune a me fungi i hiki iho mailoko o kānaka ma ka ili. XIX. Aiiay a Mānoa Ua pâʻani 'o ia ma ka epidermis. He aha ka mea? He He maikai me mechanical ke'ākeʻakeʻa mai i wale, aole e ae, e kiʻi i kekahi mea hoʻomaʻi, koʻohune, fungus a parasite i loko o ke kino, ma o na la li nui ma laila.

Ole melanocytes a me ka make keena o na epidermis mana i ole eeiaeea. Epithelial keena hana me ke ÿano o ke'ākeʻakeʻa mai, a me ka melanocytes -'ōnohi. Kēia 'o ia hoʻi i ka cuticle i malama i ka poino a me ke omoāea o ka wai, a me ka pigment keena - mai ultraviolet pāhawewe. A pau ia i 'ae ke kanaka e ke hakuloli i ka rula e ana i loko o ka maʻamau honua. Ma hope o nā mea a pau, o ka ili i ae i ke kūpono 'ana o ka meaola mai i ke kanaka Hawaiʻi, mai o ka wai a me ka naʻi i ka aina.

Ke kumu nui hiʻona o na epidermis

Nā papa o ka ili phylogenetically Hawaiʻi no ka hoʻolako 'ia kekahi mau hana. Ke epidermis o na dermis ua papahana e hoʻopale ai i ku e me mechanical, physical a me ka Nine Inch 'ole. Ua ua pono e kali i ka poho o ka loli i hiki evaporate mai kona alo aku ma hope o ka secretion o ka hou glands wale. Ua loaʻa kekahi papa hana no ka physiological loli kulu mai i ke kino ma ka ili.

Inā na epidermis mai i ka mea hoʻonani wahi o Hawaii, ua noonoo, me ka maopopo i ka mea kēia 'kūʻiʻo. Keia ili, ahu iho e ole i wrinkles a me scars, eiaʻaʻohe ipu koko. Ua Ua manaʻia e maholahune o 'ona, mai ka ipu koko o na dermis o ka ili. No laila, kona wale mea hoʻonani pilikia i na kēia: hyperkeratosis (ʻia naʻe epidermis papa) a me ka ili kaha onionio. Ka paioʻana i kēia mauʻike manaʻo, a me ka psoriasis, a me ka lapaau pono ai i ka palapala noi o nā mea hoʻonani.

Pathology o na epidermis a me ka melanocyte

Aia i kekahi mau waeʻano o ka maʻi i hiki ae aku i ka epidermis. He aha ka mea a pehea ka ikepili Hawaii i hoikeia mai, heluhelu ma lalo nei. Ka mua waeʻano - mai pili me ka māhuahua multiplication o ka epidermal basal, ahu iho keena. I ka maʻi ua kapaia psoriasis. Aia Ua hoi he congenital ana - ichthyosis, ma i ke kamaiki ua, ua hanau me ka hyperkeratosis a me ka mea ole viable. I ka lua o ka pūʻulu o nā maʻi o na epidermis - kaʻeho. Mai na epidermis ke hoʻomōhala basal halepaahao carcinoma a me ka melanoma. I ka la mahope originates mai melanocytes.
