Hiʻona o ka 'ole o epithelial'aʻaʻa. Characterization o epithelial nā'aʻaʻa

Kēlā me kēiaʻano o ka'aʻaʻa i ka ai iiiaanoaa o ano hiʻona. Ka mea, e moe ana ma nā 'ano o ka' ole, he lākou o functionalities, ke kumu, ka ano o ka IeAIIeXIAaIENʻano papa hana. E emi iho i kēia mau nā'aʻaʻa hiki ia ma luna o kekahi mau ana hoʻohālike, akā, me ka loa, he pono ole hana morfofunktcionalnaja affiliation. Oia ka Mea Maluna o ka'aʻaʻa e leie aku no ka 'oi kelakela, a pili ia i emi iho type kēlā me kēia. Ke kaumaha ma muli o ka morphological a me ka ooieoeiiaeuiuo hiʻona maopopo i ka hahai ana i ke ano o na'aʻaʻa: epithelial (ka uhi), musculoskeletal a me ko mākou hopohopo trophic Muscle.

Oi loa o ka 'ole o ka epithelial'aʻaʻa: mau morphological a me ka ooieoeiiaeuiuo na hoailona

Ua pili ia i ka epithelium o ka pae ana o fabrics, hoʻomano māhele aku i loko o ke kino. Ka mea, ke oko a ma ka molekumu o, oa e hoʻomōhala mai ka ectoderm, mesoderm a endoderm, a hana kekahi mau hana.

A papa inoa o ka pono a me ka morphological ooieoeiiaeuiiai hiʻona ano o epithelial nā'aʻaʻa:

1. Ua ninoieo o aeee kapaia epithelial keena. Ma waena o ia ma laila, ua maalea intermembrane nahā i ma a ole intercellular waiwai. Ia, ma ka huli, he nadmembranny eiiieaena (glycocalyx). Ua mea ma kona mau keena e komo aku ai i ka waiwai, a me ka mea, ma ia loko, mai ka ia halepaahao.

2. keena o epithelial 'aʻaʻa e loa anuanu, i kumu no ka ho okumu ana o papa. Ka mea, o ko lakou alo e leie aku ka'aʻaʻa e hana kona oihana. Aoao o aeee i kekahi i kekahi hiki e okoa: Via desmosomes, nahā i a kokoke hui 'ana.

3. kihi e hui ai me epithelial nā'aʻaʻa, a i hoʻonohonoho kekahi ma luna o ka mea'ē aʻe, i hookaawale ai i ka basalʻili lahilahi oia hoi o nā polokina, a carbohydrates. Kona mānoanoa He 100 HI - 1 micron. Loko epithelia i na moku ke koko, a no ia mea, i ko lakou diffusely mana ma ka hale ilaloʻili lahilahi.

4. No ka mea epithelial keena wehewehe aku ma morphofunctional polarity. Ka mea, i ka basal a me apical pou. Ke nucleus o epithelial aeee aia kokoke i ka basal, a kokoke i ka cytoplasm a pau mea i ka apical. Aia paha ia he mau huhui o cilia a me microvilli.

5. Epithelial nā'aʻaʻa i okoa pono-i ho'ākāka 'hana e regenerate. Ka mea, i wehewehe aku ma ke alo o ke kumu, a me ka differentiated keena cambium.

Kekahi mau hoʻokokoke mai i ka Mea Maluna

Ma hua'ōlelo o ka evolution o ka epithelial aeee i hanaʻia ma mua nā'aʻaʻa keena. ʻO ko lākou iniiaiie kuleana pili i ua i delimitation o ke kino, mai ka mea mawaho kaiapuni. Ma ka keia kahua o evolution o ka epithelial'aʻaʻa i kekahi mau hana i loko o ke kino. E like me ia i kēia hiʻona, hoomaopopo i kēia mauʻano o nā fabrics: integumentary, omo, excretory, a me nā secretory. Mea Maluna o epithelial nā'aʻaʻa morphologically i loko no o ka kinona, a me ka helu o epithelial papa i loko o ke kahua. No laila, līkaia no hookahi a me ka nunui-pona epithelial nā'aʻaʻa.

Ano o ka hookahi-, ahu iho, hookahi epithelia

Ke mall hiʻona o ka epithelial'aʻaʻa, a ua kapaʻia he hookahi-ahu iho la, moe i loko o ka mea ana i ka? Aieeeua ninoieo o ka hookahi ahu iho la ka keena. A hiki i wehewehe aku na keena a pau ma ke kahua o ke ki eki e e e kamailio e pili ana i ka hookahi-ahu iho hookahi-lalani epithelium. Epithelial kiʻekiʻe ke kumu no mahope Mea Maluna, e like me ka mea i hōʻike i ke alo i loko o ke kino pelane, cubic a me ka paukūʻolokaʻa (prismatic) hookahi-lalani hookahi-, ahu iho epithelium.

Single-, ahu iho squamous epithelium o IIeEeAIEUIeXAIIUE wahi o na maʻiʻaʻai i loko o ka naehana (alveoli), uuku ducts glands, testes, waena pepeiao lua, serous membranes (mesothelium). I hana mai i ka mesoderm.

Kekahi kumu IIeEeAIEUAA monolayer i cuboidal epithelium ducts glands a me tubules o nā puʻupaʻa. Ke kiʻekiʻe a me ka laula o ka hola o ia keena, ka nuclei i ua hoʻokōʻia, a ua aia ma ka waena konu o ka halepaahao. Ke me Kinohi paha e okoa.

Kēiaʻano o ka hookahi-, ahu iho hookahi-lalani epithelial'aʻaʻa like me ka paukūʻolokaʻa (columnar) epithelium, Aia i loko o ka gastrointestinal'āpana, ducts o na glands,ʻaʻa puʻuwai o kaʻohiʻana ducts. Ke kiekie o na keena, ua oi aku ia mamua me ka nui loa o ka laula. Ua loaʻa he okoa kumu.

Ano o ka hookahi-ahu iho nunui-lālani ciliated epithelium

Inā he hookahi-ahu iho epithelial'aʻaʻa ano he ahu iho la ka keena o okoa kiekie, a laila mākou e kamaʻilio e pili ana i nunui-lalani ciliated epithelium. Kēia'aʻaʻa laina o ka ili o ka Hawaiian Airlines a me kekahi mau māhele o ka reproductive'ōnaehana (seminal'āpana, a jajtceprovodov) mall hiʻona o epithelial'aʻaʻa type ninoieo i loko o ka mea i kona keena, he o ekolu ano: pōkole intercalary, lōʻihi ciliated a me ka poepoe lā ia. A pau o ia i hoonohonoho i loko o ka hookahi, ahu iho, akā, intercalary aeee mai i hiki i ka luna kae o ka? Aieeeua. I ka ulu ana mai, ka mea, differentiate a lilo ciliated paha poepoe lā ia. A hiʻona o ke alo o ciliated keena ma ka apical kaupoku o ka helu nui o cilia, e hiki i ka paka bitumena poepoe lā ia keena.

Mea Maluna a me ka 'ole o ka stratified epithelium

epithelial keena hiki ke hana mau papa. Ka mea, i aia kekahi ma luna o ka mea 'ē aʻe, no laila, i loko o ka hui' ana me ka hale ilaloʻili lahilahi mea i hiki wale i mea nui e waiho, i ka basal, ahu iho o epithelial keena. Ua loaʻa anei i keena a me cambial. E like me ka mea, differentiate, laila, neʻe waho. Ke ana no ka Mea Maluna o ka wā e hiki mai kinona o na keena. No laila, līkaia stratified squamous keratinizing, stratified squamous epithelium neorogovevayuschy a me ka hoʻololi.

Ano o stratified squamous keratinized epithelium

I hana mai i ka ectoderm. Mai keia'aʻaʻa maupaʻa epidermis, i mea o kaʻilikai o kaʻili, a me ka maʻi hapa o ka rectum. e loaʻa elima papa o aeee hiʻona o ka 'ole o kēia' ano o epithelial'aʻaʻa: ka basal, spinous, granular, ka lā'ī a me ka horny.

Ke basal, ahu iho nei he hookahi lalani loihi paukūʻolokaʻa keena. Ka mea, e paa i ua nakiiia ma i ka hale ilaloʻili lahilahi, a i ka hiki ke paʻi. Ka mānoanoa o ka spinous, ahu iho nei mai ka 4 a hiki i 8 lalani spiny keena. Ma ka granular, ahu iho - 2-3 lālani o aeee. Epithelial aeee i ka flattened kinona, anuanu Kora naʻEsau. Ka lā'ī, ahu iho - ka helu o ka make keena 2-3. Hea ka mea me ka ili o ka stratum corneum, ua haku o ka ai iiiaanoaa o ka lalani (100) 'ano apau loa i ka palahalaha make keena. Kēia horny unahi, i loko o a he mea he keratin keratin.

I ka hana o keia'aʻaʻa mea e hoʻopale ai i ka hohonu nā'aʻaʻa ku mawaho poino.

Mall hiʻona o ka stratified squamous epithelium neorogovevayuschy

I hana mai i ka ectoderm. Ma wahi o IIeEeAIEUAA i ka cornea, ku una lua, esophagus a me ka hapa o ka'ōpū o kekahi holoholona? Ueo. Ua he ekolu mau papa: basal, prickly a me ka palahalaha. Ke basal, ahu iho ma ka hui 'ana me ka hale ilaloʻili lahilahi ninoieo o prismatic keena nona ka nui ka'ololaha nuclei i kekahi mau mea' oni iki i ka apical kaupoku. Ke keena o keia ahu, kaʻana, hoʻomaka ka hoʻokikina mai. Penei, ka mea, e hou i ka hui 'ana me ka hale ilaloʻili lahilahi, a hele aku i loko o ka prickly, ahu iho. He mau papa o keena o ole polygonal kinona, a me ka ka'ololaha nucleus. Prickly ahu iho la i ka ili - i lalo, ahu iho o ka mānoanoa o ka 2-3 keena.

malumalu epithelium

Mea Maluna o epithelial nā'aʻaʻa ua hoakaka no ka ai-kapaia malumalu epithelium i hana mai i ka mesoderm. IIeEeAIEUAA - ʻaʻa puʻuwai pelvis, ureter a me ka bladder. Ekolu papa o aeee (basal, waena, a me ka penaʻana) i loa okoa i ka 'ole. No ka basal, ahu iho wehewehe aku ma ke alo o ka poe liilii, cambial keena o kekahi mau ano e moe ana ma luna o ka basalʻili lahilahi. Ka palapala, ahu iho aeee i ka malamalama, a me ka nui, hiki e okoa ka helu o ka lalani. Ua hilinaʻi nui ma ana i ke kino ua piha. Na ka penaʻana, ahu iho keena i ke ahiahi, nui, ka mea i wehewehe aku e mau Kora naʻEsau, a polyploidy, i hiki hoi ke opa i ka mucus, a ua ālai 'ho okumu ili mai nā palapala hui' ana me mimi.

glandular epithelium

epithelial'aʻaʻa characterization ua kāpili me kekahi hōʻike no ka 'ole a me ka hana ana o ka ai-kapaia glandular epithelium. Kēiaʻano o ka'aʻaʻa ua hoʻomano māhele aku i loko o ke kino, e hiki no i ka paka, a pee kuikawa waiwai kona keena - mea huna. Ke nui, kinona, 'ole glandular aeee ka loa like, e like me ka mea haku mele a me ka mea huna specialization.

Ke kaʻina hana ma i kona wahi hilahila i hana pono luna 'i loaa mai ma kekahi mau kahua o ka hoʻonaʻauao, a ua kapaia secretory pōʻaiapuni.

Hiʻona o ka 'ole o epithelial'aʻaʻa haku o glandular keena, ka hoʻopiʻi kuhikuhi i kona manao. No ka mea, i kēiaʻano o ka lole ua hana kino, i ka papa kuhikuhi hana o ka a, e ia i ka hanauna malu. Mau nā loko kapa glands.
