The ciliary thupi (ciliary thupi): kapangidwe ndi ntchito. maso galimoto

Choroid amene ali ndi udindo kwa malawi, anatengera ndi chakudya retinal - mbali yofunika kwambiri ya dongosolo la mwana wa m'diso la. Amakhala ndi magawo angapo, mmodzi amene ali ciliary (ciliary) thupi. Iwo wapangidwa za kuchuluka kwa ziwiya ndi maselo, kapangidwe ka ndilo khalidwe la minofu yosalala.

Maselo amenewa imakonzedwa mu zigawo, aliyense amene ali malangizo yake. Izi zipangitsa magwiridwe kabwino ka ciliary thupi, ndiko kukhala ndi zizipezeka ulusi yake minofu ndi kuonetsetsa mphamvu diso kuganizira pa mtunda osiyana (malawi). Ntchito inanso yofunika ya maphunziro imatengedwa ziziyenda ndi kukhalabe kuthamanga anakhumba mwa mwana wa m'diso la.

Kapangidwe ka diso thunthu

Nanga otchedwa gawo la choroid, ndipo kodi ntchito zake? Kuti timvetse, muyenera kuganizira kapangidwe ka diso. Kaswili chimasiyanitsa zithunzi limba 4 Gawo:

1. Mbali zotumphukira, wotchedwa komabe anazindikira (amaphatikizapo mwana wa diso mwachindunji, akuluakulu diso chitetezo, ziwalo wamng'ono ndi dongosolo akulu ndi udindo kayendedwe ka mwana wa m'diso la).
2. Njira wopangidwa mwa chamawonedwe mitsempha, mphambano ndi njira.
3. Zooneka malo mu subcortex lapansi.
4. The malo apamwamba zithunzi, zomwe zili pambuyo pawo wa kotekisi ubongo.

Diso - ndi yovuta kwambiri kuwala chipangizo kuti akutsimikiza chithunzi pansipa diso.

Ntchito yaikulu ya thupi amatchedwa kufala okhulupirika a fano mitsempha chamawonedwe. Ndipo ikukhudza zigawo zikuluzikulu zonse za mwana wa m'diso la:

• diso;
• ndi zapambuyo chipinda;
• Iris;
• mwana;
• mandala;
• vitreous nthabwala ;
• diso;
• sclera;
• choroid (zoona, gawo la izo ndi ciliary thupi la diso).

Malowa ali pamtunda, monga momwe chithunzi pakati pa sclera Iris ndi diso.

The ciliary thupi: kapangidwe ndi ntchito

Ku maganizo a thunthu anafotokoza mbali ya mwana wa m'diso la - chatsekedwa annular chithunzi kumbuyo Iris, ndi scleral chipolopolo maso. Kakonzedwe kotero, poyamba salola kudzifufuza mwachindunji kwa ciliary thupi.

Poganizira structural chimango maphunziro, zigawo zake awiri akhoza kuwasiyanitsa: ndi ciliary ndi lathyathyathya.

• Akangofika pafupi m'mphepete mwa zida, ndipo m'lifupi mwake kuzungulira 4 mm.
• The chachiwiri, ciliary, m'lifupi pazipita zili ndi 2 mm. Ndi pa izo pali njira yapadera (ciliary kapena ciliary), amene pamodzi zimapanga ciliary korona. Iwo amagwira ntchito mapangidwe madzimadzi mkati diso. Izi zimachitika chifukwa kusefera magazi mu kuchuluka kwa mitsempha amene angatithandize kwenikweni wina wa njira ndi Zodabwitsa ndizakuti, mawonekedwe mbale ngati.

Poganizira ciliary thupi pa mlingo ma, tikuona kuti tichipeza zigawo ziwiri za mesodermal ndi neuroectodermal. Kapangidwe tichipeza mitundu awiri minofu - connective ndi akulu. Koma neuroectodermal okha kukhala yekha maselo zaminyewa, pamaso lake chifukwa kufala kwa otsiriza ndi wosanjikiza diso.

Likukhalira ngati magawo mkate, zigawo amene anakonza motere (kuchokera zozama)

• akulu wosanjikiza;
• mtima wosanjikiza;
• chapansi nembanemba;
• pigment epithelium;
• popanda pigment epithelium wosanjikiza;
• mkati kulekana Kakhungu.

Kenako, tikambirana za Gawo la ciliary thupi, womwenso diso chithunzi.

akulu wosanjikiza

wosanjikiza Izi amakhala ndi akatumba angapo, kuyenda mu madera osiyana: kotenga, zozungulira ndipo zozungulira. ulusi Longitudinally osiyana minofu otchedwa Brucke minofu, ndi kukhala gawo la wosanjikiza lakunja. Pansipa iwo radially imatsogoleredwa minofu Ivanov. Ndipo kutseka ali circularly imatsogoleredwa minofu Mueller.

Cholinga chachikulu cha aliyense wosanjikiza ndi kutenga nawo mbali mu ndondomeko luso diso adzayeretsa masomphenya pa mtunda osiyana (malawi). Izi zimachitika motere. The gawo lamkati la ciliary thupi amalankhulira ndi kunja kwa disolo (kapisozi ake) kudzera ciliary lamba wopangidwa mwa kuchuluka kwa ulusi thinnest. Chinthu nyumba imeneyi ndi kukonza mandala mu malo, ndi kuthandiza ciliary minofu nthaŵi accommodative.

Ulusi wa ciliary lamba otchedwa zonulyarnymi akadali ogaŵikana mitundu iwiri: kutsogolo ndi kumbuyo. The kumatidwa kuti yamphamvu ndi zapambuyo kapisozi mandala m'dera ndi wachiwiri kwa yamphamvu ndi moyenera, kumbuyo. Chifukwa cha maganizo awo ndi zosangalatsa za minofu ciliary imafalikira mandala chipolopolo, ndipo chinakhala zambiri anamaliza kapena zambiri elongate ngati ndondomeko moganizira diso pa mtunda wina.

mtima wosanjikiza

Kapangidwe ka wosanjikiza izi sasiyana kwambiri kwa kapangidwe ka choroid, ndi kupitiriza limene iye. The zikuchokera mtima wosanjikiza zikuphatikizapo makamaka mitsempha zamitundu yosiyanasiyana. Ichi ndi chifukwa chakuti mbali yaikulu ya diso mtsempha wamagazi ili pafupi choroid, ndipo oddly mokwanira, mu ciliary thupi, koma mu gawo akulu. Zinali kuchokera ang'ono ziwiya wolumikizira ndi kulowa choroid.

chapansi Kakhungu

The kupitiriza kwa choroid ndi wosanjikiza izi. Pa mbali mkati yokutidwa ndi mitundu iwiri ya maselo zaminyewa: amelanotic ndi pigment. Izi mitundu ya maselo ndi kanthu koposa sanali kugwira ntchito kwa diso. Pambuyo pawo ndi kuchepetsa Kakhungu osati ndi wosanjikiza yomaliza ya ciliary thupi, komanso alekanitsa izo kwa nthabwala vitreous.

Udindo thupi la ciliary thupi

ntchito zingapo zofunika za ciliary thupi tingaone:

• Kuthandiza pa malawi, ndi luso kusintha mawonekedwe a disolo kapisozi kudzera minofu wosanjikiza wa ciliary thupi. malawi operekedwa ndi kusintha zolondola mkati 5 Diopters.
• Kupereka okwanira madzimadzi intraocular, chifukwa chakuti ciliary thupi limapangidwa ambiri ziwiya ndipo chotero, ali ndi magazi wabwino kotunga. Kenako, kudzera mwa madzimadzi izi chofunika panthawi ina kuthamanga pa zigawo zina za mwana wa m'diso la.
• Kusunga kuthamanga yake mwa diso, yomwe ndi imodzi mwa zinthu kupulumutsa khirisipi, bwinobwino.
• dongosolo mtima nawo kuonetsetsa kundipatsako kwa ciliary thupi, chakudya ndi diso.
• thupi Ciliary amachita monga kuthandiza a Iris.

Kudwala wa ciliary thupi

Mu mankhwala, allocated matenda, ndilo phunziro kwa ciliary thupi:

• Khungu. Mu matendawa kusokonezedwa mgwirizano pakati pa apanga intraocular madzimadzi ndi outflow ake.
• Iridocyclitis. Iwo amakhala ndi maonekedwe a njira yotupa mu ciliary thupi.
• Yafupika kuthamanga mkati diso, ndi kuchepetsa m'menemo buku la madzimadzi. Zimenezi zingachititse kuti atupa zigawo a epithelium lapansi.
• Zotupa mu ciliary thupi. Nthawi zina, angakhale zabwino.
• pathologies zosiyanasiyana chibadidwe chikhalidwe.

Poyamba chizindikiro cha vuto m'pofunika pochitika kudzifufuza wapadera, kulola kuona ciliary thupi la diso, kupeza zimene pathological njira chikuyambira, ndipo ankachita ngati n'koyenera.

chifukwa

Polongosola mwachidule, m'pofunika kunena kuti ciliary thupi, kukhala gawo la choroid, ndi udindo kwa chiwerengero cha ntchito zofunika mwa mwana wa m'diso la. Pakati pawo - ndi normalization wa kuthamanga mkati diso ndi chingakuthandizeni wake, kaphatikizidwe wa madzimadzi intraocular, yokonza otaya yachibadwa magazi minofu ozungulira ndipo, ndithudi, amene amasamalira wa malawi. Munthuyo ayenera kukumbukira kuti matenda ciliary Thupi zimaonekera pa boma onse a munthu.
