The ciliary muviri (ciliary muviri): marongerwo uye ushande. Driving meso

Choroid riri kukonzera pekugara, kwadzakabva uye retinal chikafu - hunokosha chaizvo chikamu nemamiriro yeziso. Inoitwa anoverengeka zvikamu, rimwe riri ciliary (ciliary) muviri. It rinoumbwa munhu muzvizhinji hari masero, sechivako chiri maitire wakatsetseka tsandanyama.

Masero aya akarongwa akaturikidzana, chimwe nechimwe chine nhungamiro wayo. Izvi zvinoita kwakakodzera functionality pamusoro ciliary muviri, izvo kuramba dzirambe dziripo warwo tsandanyama fibers uye kuona inogona ziso pfungwa panguva dzakasiyana marefu (pokugara). Chimwe basa rinokosha dzidzo anoonekwa kudzikamisa uye kuramba zvinodiwa kumanikidzwa mukati yeziso.

The nemamiriro ziso anatomi

Saka chii chinonzi inonzi chikamu choroid, uye chii vari mabasa ayo? Kuti tinzwisise, unofanira kufunga sechivako ziso. Anatomy chinosiyanisa kuona nhengo 4 huru zvinoriumba:

1. The peripheral chikamu inonzi ichiri akaziva (zvinosanganisira zvakananga yeziso, ziso dziviriro zviremera, omurume nhengo uye tsandanyama kwava kukonzera sangano yeziso).
2. Makwara raiumbwa optic etsinga, mharadzano uye nzira.
3. Visual nzvimbo iri subcortex.
4. The yepamusorosoro ziso nzvimbo, iyo chiri panzvimbo rwemberi chepfungwa cortex.

Yeziso - chinhu yakaoma chaizvo Manyiminya mudziyo inobvumirana chiripasi ziso.

The chikuru basa mumuviri anonzi vakatendeka kwemashoko mufananidzo wacho optic etsinga. Uye zvinosanganisira zvose zvinoumba yeziso:

• cornea;
• ari Anterior kamuri;
• Obert;
• mboni;
• gogorosi;
• vitreous kusetsa ;
• the retina;
• sclera;
• choroid (chaizvoizvo, chikamu ndicho ciliary mutumbi ziso).

Riri, sezvinoratidzwa dhayagiramu pakati sclera, Iris uye the retina.

The ciliary muviri: marongerwo uye mashandiro

Kubva pfungwa maonero anatomi akatsanangura chikamu yeziso - a namahwindo annular mufananidzo seri Iris, scleral deko maziso. Urongwa hwakadaro, sezvinei, haibvumiri wakananga kuzviongorora ciliary muviri.

Tichitarisa STRUCTURAL yechinangwa dzidzo, yenhengo dzayo mbiri inogona musiyano pakati ciliary uye sandarara.

• First anouya pedyo kumucheto giya, uye yakafara ari kumativi 4 mm.
• Wechipiri, ciliary, vaifanira kufara zviri 2 mm. Zviri pamusoro payo pane chinokosha pezvakaitwa (ciliary kana ciliary), izvo pamwe chete zvinoumba ciliary korona. Ivo dzinoshanda paumbwe mvura mukati ziso. Izvi zvinoitika nokuda ropa filtration ari muzvizhinji rwengarava ropa kuti pinda sezvariri nomumwe pezvakaitwa ane Sezvineiwo, ndiro-kufanana chimiro.

Kufunga ciliary muviri panguva cellular vanochiva tinogona kuona kuti inoitwa maviri akaturikidzana ose mesodermal uye neuroectodermal. Nemamiriro ine mhando mbiri yokutanga zvinyama - connective uye tsandanyama. Asi neuroectodermal kungogumira kuva chete epithelial masero, kuvapo chiri kukonzerwa kupararira ekupedzisira aine marongera of the retina.

Zvachinja kubva layered cake mhando, akaturikidzana zviri kurongwa sezvinotevera (kubva pakadzika)

• tsandanyama rukoko;
• vascular rukoko;
• bhesimendi Kamudzira;
• ruvara epithelium;
• pasina ruvara epithelium rukoko;
• womukati kuparadzana membrane.

Next, tichakurukura chikuru zvinoumba ari ciliary muviri, izvo zvinosanganisira ziso chati.

tsandanyama rukoko

rukoko urwu kunoratidzwa akawanda tsandanyama, achifamba kwakasiyana-siyana: longitudinal, TOUR uye tenderera. Longitudinally yakasiyana tsandanyama fibers rinonzi Bridge tsandanyama, uye kuva chikamu rokunze rukoko. Below vavo radially rinotungamirirwa tsandanyama Ivanova. Zvimiti vari circularly rinotungamirirwa tsandanyama Mukanova.

Chinangwa chikuru chemusha mumwe nomumwe rukoko ndiko kubatanidzwa nedanho ziso anogona kuchenesa muchiratidzo dzakasiyana marefu (pokugara). Izvi zvinoitika sezvinotevera. The menzvimbo ciliary muviri anokurukura kunze izvo (Kamudzira kwayo) Via ciliary bhandi ina muzvizhinji pakati thinnest fibers. The chinhu mamiriro uyu kugadzirisa izvo panzvimbo, uye kubatsira ciliary tsandanyama panguva accommodative kwendangariro.

The fibers of ciliary bhanhire rinonzi zonulyarnymi vachiri rakakamurwa mhando mbiri: mberi neshure. Chokutanga vasiyana ichinaya uye Anterior Kamudzira izvo nzvimbo uye wechipiri kuti ichinaya uye maererano, neshure. Nokunetseka kwavo uye kutandara pamusoro ciliary tsandanyama iri zvitange izvo goko, uye inova woita, kana kupfuura elongate sezvo muitiro kungotarira ziso pane imwe kure.

vascular rukoko

Sechivako rukoko urwu haana kumbosiyana zvikuru kubva nemamiriro choroid, ari kuenderera yaari. The sezvamunoita vascular rukoko zvinosanganisira kunyanya mutsinga kuti hukuru siyana. Izvi imhaka yokuti hombe chikamu ziso tsinga yaiva pedyo choroid, uye, oddly zvakakwana, ari ciliary muviri, asi mune tsandanyama chikamu. Yakanga kubva diki arterial midziyo uye kupinda choroid.

bhesimendi Kamudzira

The kuenderera choroid uye rukoko urwu. On menzvimbo wakafukidzwa nezvemarudzi maviri masero epithelial: amelanotic uye ruvara. Mhando idzi masero hapana kupfuura isiri kushanda the retina. Shure wavo vakaomerwa Kamudzira kuti kwete chete ndeyekupedzisira rukoko ari ciliary muviri, asi anoparadzana kubva vitreous zvinosetsa.

The vasiri rokuva ciliary muviri

wandei inokosha mabasa ose ciliary muviri vangazivikanwa:

• Kuitawo pekugara, pamwe anogona kuchinja pezvakaita izvo Kamudzira kubudikidza tsandanyama rukoko yacho ciliary muviri. pekugara inopiwa yakarurama kugadziridza mukati 5 Diopters.
• Kupa vanoverengeka intraocular mvura yakakwana, nokuti kuti ciliary muviri unotora vakawanda midziyo uye, naizvozvo, ane yakanaka ropa rive. Naizvozvo, achishandisa Urume ichi kunodiwa dzimwe nguva kumanikidzwa zvimwe zvinoumba yeziso.
• Kuramba zvakakodzera kumanikidzwa mukati ziso, inova imwe mamiriro kukumikidza Crisp, chiono chakajeka.
• vascular ezvinhu munyaya kuunza nerubatsiro ciliary muviri, anoupa zvokudya uye the retina.
• Ciliary muviri anoita somunhu anotsigira Iris.

Zvokurwara of ciliary muviri

Mukurapa, dzinounzwa chirwere, riri pasi ciliary muviri:

• Yemaziso. In chirwere ichi vakanetseka zvakanyatsoenzana pakati synthesized intraocular mvura yaro water drainage.
• Iridocyclitis. It kunoratidzwa chitarisiko anogumbura pezvakaitwa ari ciliary muviri.
• The akaderedza kumanikidzwa mukati ziso, nokuderedza bhuku Urume mairi. Izvi zvingaita kuti kuzvimba akaturikidzana ari epithelium.
• Namamota ari ciliary muviri. Mune zvimwe zviitiko, vangave substandard.
• Various pathologies yokusafa hunhu.

At chiratidzo dambudziko rokutanga zvakafanira kupfuura munhu kuongorora chaiyo, vachibvumira kuona ciliary mutumbi ziso, kuti uzive chii pathological urongwa anotanga, uye kurapwa kana zvakakodzera.

mugumisiro

Achiratidza, zvinokosha kutaura zvakare kuti ciliary muviri, kuva chikamu choroid, riri basa dzinoverengeka zvinokosha mashandiro mukati yeziso. Pakati pavo - the normalization zvavaida mukati ziso uye kuramba takatsiga vake, kwetunhu intraocular fluid kwerunyararo zvakajairika ropa riyerere iri dzakapoteredza zvinyama uye, chokwadi, munyaya muitiro akkommodasie. Mumwe kuyeuka kuti zvirwere ciliary muviri achapiwa vakafungisisa mukuru mamiriro ari munhu.
