Ko te tinana ciliary (tinana ciliary): hanganga me te mahi. Driving kanohi

Kamo i te kawenga mō te noho, urutaunga me te kai tuaroa - he wahi tino nui o te hanganga o te 'Afio. Kei a ia ko te maha wahi, tetahi o i te ciliary tinana (ciliary). Kei te tito te reira o te plurality o oko me ngā pūtau, he āhuatanga o te uaua maeneene te hanganga o nei.

E whakaritea ana ēnei pūtau i roto i te papa, i ia o nei he ona ake aronga. Ka āta whakarite tēnei taumahinga tika o te tinana ciliary, i te mea ki te mau tonu i te supply tonu o ona ake weu uaua, me te whakarite i te kaha o te kanohi ki te arotahi i tawhiti rerekē (noho). whakaaro tētahi atu mahi nui o te mātauranga kei te ki te ū me te mau tonu i te pēhanga e hiahiatia ana i roto i te 'Afio.

Ko te hanganga o te anatomy kanohi

Na he aha te mea he i huaina wahi o te kamo, me aha e ona mahi? Hei matau, e hiahia ana koe ki te whakaaro i te hanganga o te kanohi. Anatomy titore te ataata okana 4 wāhanga matua:

1. Te wahi piringa, ka karanga kite a tonu (ngā reira 'Afio tika, mana tiaki kanohi, whekau awhenga, me te pūnaha uaua te kawenga mō te kaupapa o te' Afio).
2. Huarahi arā, o te io whatu, pūtahitanga me te ara.
3. pokapū Ataata i roto i te subcortex.
4. Ko te pokapū ataata teitei, e kua kei i te muri o te uho kaka.

Ko te 'Afio - ko te whakaaro whatu rawa uaua e haapapu te hoahoa i raro nei te kanohi.

huaina te mahi matua o te tinana kei te te tuku pono o te whakapakoko te faatae te. A tā reira nga wāhanga katoa o te 'Afio:

• kirikanohi;
• te ruma mārōrō,;
• iris;
• te whatupango;
• arotahi;
• tangiwai ;
• etine;
• teatea;
• kamo (i roto i te meka, he wahi o reira te tinana ciliary o te kanohi).

Kei te tū te reira, e whakaaturia ana e te hoahoa i waenganui i te teatea, iris me etine.

Ko te tinana ciliary: hanganga me te mahi

Mai i te wāhi o te tirohanga o te anatomy whakaahuatia wahi o te 'Afio - he ahua annular kati i muri nga iris, he kanohi anga scleral. he whakaritenga taua, rokohanga, e kore e tukua te whakamātautau tika o te tinana ciliary.

Whakaaro i te anga hanganga o te mātauranga, e taea te kitea ona wāhanga e rua: te ciliary me flat.

• Tuatahi mai tata ki te mata o te taputapu, me tona whanui, ko te a tawhio 4 mm.
• Ko te tuarua, ciliary, he ki runga ki te 2 mm te whanui mōrahi. Ko runga reira i reira he tukanga motuhake (ciliary ciliary ranei), e tahi kėia te karauna ciliary. E whai wāhi tika ratou i roto i te hanganga o te wai i roto i te kanohi. tupu tenei e tika ana ki te filtration toto i roto i te plurality o oko toto e tomo mooni ia o ngā tukanga ka Ratau, āhua pereti-rite.

Whakaaro i te tinana ciliary i te taumata pūtau, e taea kite tatou e ngā reira o rua paparanga o mesodermal me neuroectodermal. Kei te hanganga o nga momo tuatahi e rua o te kiko - tūhonohono, me te uaua. Ko neuroectodermal iti ki ia i te pūtau epithelial anake, te aroaro o te mea e tika ana ki te horapa o te muri ki te apa o te etine.

Huri i te reira i roto i te ahua o te keke paparanga, paparanga e kua whakaritea e whai ake (i te rire)

• paparanga uaua;
• paparanga iaia;
• whawhe membrane;
• epithelium te ngarahu;
• kahore apa ngarahu epithelium;
• membrane wehenga ā-.

Next, ka aparau i tatou nga wāhanga matua o te tinana ciliary, e ngā hoahoa kanohi.

paparanga uaua

āhuatanga tēnei apa e rave rahi uaua, e haere ana i roto i ngā tohutohu rerekē: ahopou, toropā, me te porohita. Ōna rerekē muka uaua huaina uaua Brücke, me te wahi o te paparanga o waho. Kei raro ratou e radially whakahaua uaua Ivanov. Na kei te circularly whakahaua katia te uaua Mueller.

Ko te whāinga matua o ia paparanga, ko te ki te whai wāhi i roto i te tukanga o te kaha te kanohi o ki te ūkui kite i tawhiti rerekē (noho). Tenei tupu e whai ake. Ko te roto rawa o te tinana ciliary fetu'utaki ki te waho o te arotahi (tona capsule) mā whitiki ciliary arā, o te plurality o te muka thinnest. Ko te ahanoa o tenei hanganga ko ki te whakatika i te arotahi i roto i te tūranga, me te āwhina i te uaua ciliary i roto i ngā tukanga accommodative.

wehea tonu nga muka o te whitiki ciliary huaina zonulyarnymi ki e rua ngā momo: te mua, a muri. Ko te piri ki te rohe capsule arotahi weheruatanga ao, me te mārōrō tuatahi, me te tuarua ki te weheruatanga ao, me te i runga i, te tuarongo. Nā ki to ratou mānukanuka me te whakangā o te uaua ciliary tuku te anga arotahi, a ka riro te reira i te atu porotaka, ranei atu elongate rite te tukanga o arotahi te kanohi i te tetahi tawhiti.

paparanga iaia

E kore e te hanganga o tenei paparanga rerekē nui i te hanganga o te kamo, ko te hokohoko atu o nei ko ia. Ko te apa hanganga iaia ngā nuinga uaua o ngā rahi. Ko tenei e tika ana ki te meka i te wahi nui o te iatuku kanohi kei tata te kamo, ka, piro nui, i roto i te tinana ciliary, engari i roto i te wahi uaua. Ko reira i te oko iti matua, me te tomo i te kamo.

membrane basement

Ko te haere tonu o te kamo, me te ko tenei apa. I runga i te wahi i roto rawa taupokina te ki e rua ngā momo o ngā pūtau epithelial: amelanotic me te ngarahu. Enei momo o pūtau he kahore neke atu i te mahi-kore o te etine. Muri ratou ko te membrane whāiti e kore anake ko te kahu whakamutunga o te tinana ciliary, engari wehe ano hoki reira i te tangiwai.

Ko te tūranga whaiaroaro o te tinana ciliary

Ka taea te tāutuhia te maha o ngā mahi taketake o te tinana ciliary:

• Whai wāhi i roto i te noho, me te kaha ki te huri i te āhua o te capsule arotahi i roto i te kahu uaua o te tinana ciliary. noho whakaratohia e whakatikatika tika i roto i 5 Diopters.
• Whakarato i te maha rawaka o inu intraocular, e tika ana ki te meka i te tinana ciliary Kei te maha nui o oko, me te, no reira, kua he supply toto pai. I muri, i te tikanga o tenei wai e hiahiatia ana te i etahi wāhi te pēhanga ki runga i ētahi atu wāhanga o te 'Afio.
• Te whakaū i te pēhanga tika i roto i te kanohi, i te mea tetahi o nga tikanga ki te whakaora e hōu, kite mārama.
• pūnaha iaia wāhi i roto i te whakarite i te supply o te ciliary tinana, atawhai, me te etine.
• mahi tinana Ciliary rite te tautoko mo nga iris.

Māuiuitanga o te tinana ciliary

I roto i te rongoā, tohaina te mate, i te mea i raro ki te tinana ciliary:

• Papahewa. I roto i tenei mate ohorere taurite i waenganui i te inu intraocular synthesized me tona matamua.
• Iridocyclitis. Kei te āhuatanga i te reira e te ahua o ngā tukanga inflammatory i roto i te tinana ciliary.
• Ko te pēhanga iti roto te kanohi, i te whakaiti i te rōrahi o te wai ki reira. Tenei e taea e arahi ki huamo o te paparanga o te epithelium.
• Pukupuku i roto i te tinana ciliary. I roto i ētahi wā, kia waiho ratou hë.
• Various pathologies āhua tūturu.

I te tohu tuatahi o te raruraru, ko te mea e tika ana ki te tika i te whakamātautau motuhake, tuku ki te kite i te tinana ciliary o te kanohi, ki te kitea i roto i te mea tukanga pathological tīmata reira, a ka tukinotia ki te tika.

hua

Komititanga ake, he mea e tika ana ki te ano te mea e te tinana ciliary, he wahi o te kamo, ko te kawenga hoki te maha o ngā mahi nui i roto i te 'Afio. I roto ia ratou - te māori o te pēhanga i roto i te kanohi, me te tiaki i tona toenga, te ariā o te inu intraocular, tiaki o te rere toto tonu i roto i te kikokiko e karapoti ana me, o te akoranga, whai wāhi i roto i te tukanga o te noho. kia mahara tetahi e ka kia kitea mate tinana ciliary i runga i te āhua whānui o te tangata.
