Oculomotor minofu: zoyimira ndi ntchito. Minofu nawo ngodya diso

Oculomotor minofu kuthandiza kugwira kayendedwe mgwirizano pakati eyeballs, ndi yomweyi, iwo kupereka apamwamba maganizo. Kusangalala atatu azithunzi omwe tikunena chifanizo cha dziko, muyenera zonse kuchititsa maphunziro a minofu minofu. Kodi wokhulupirira kuchita, uzani katswiri pambuyo bwinobwino. Nthawi iliyonse m'pofunika wokonzeka kuthana ndi kudzikonda mankhwala.

zambiri

Diso minofu ndi mitundu isanu ndi umodzi, ndi anai a iwo molunjika ndi awiri oblique. Iwo choncho chifukwa chikhalidwe kumene mu M'mimbamo ndi (kanjira), yomwe ili, komanso chifukwa cha ubwenzi limba la masomphenya. ntchito lawo lili m'manja mwa mathero mitsempha kuti zili bokosi craniocerebral, monga:

1. Oculomotor.
2. Awatulutsira.
3. Block.

Diso minofu ndi zambiri misempha, amene angathe kupereka zikumveka molondola pamene kusuntha maso anu.

zoyenda

Eyeballs deta kudzera ulusi ambiri ingagwire kuyenda monga unidirectional kapena multidirectional. Pakuti kasinthasintha unidirectional akwana, pansi, anachoka, ndi ena, kuti multidirectional - kuchepetsa diso pa nthawi ina. magulu amenewa amathandiza kugwira ntchito mogwirizana ndi zimakhala ndi chimodzimodzi munthu m'chifanizo, chifukwa kugunda wake mbali imodzimodziyo kwa diso.

Minofu angapereke kayendedwe ka maso onse nthawi yomweyo kukwaniritsa ntchito zofunika:

1. Kayendedwe mbali imodzi. Njirayi imatchedwa verzionnym.
2. Kayendedwe mu madera osiyana. Njirayi imatchedwa vergence (mgwirizano, kusinthako).

mbali Kodi structural?

Monga tanena kale, oculomotor minofu ndi:

1. Molunjika. Ndi patsogolo malangizo.
2. Obliques ndi m'goli sitiroko mtundu ndi Ufumuyo thupi la nsalu chapamwamba ndipo m'munsi.

minofu onsewa diso kuyamba wandiweyani polumikiza mphete zomwe lozungulira akunja kutsegula chamawonedwe njira. Imeneyi, kupatulapo ali pa oblique m'munsi. Onse asanu ulusi minofu pamene n'kupanga nyuzi, amene ali misempha mkati, kuphatikizapo diso lalikulu, ndi ziwiya.

Ngati zakuya, adzakhululukidwa waona mmene oblique anapanduka m'mwamba mkati, motero kulenga unit. Komanso m'dera limeneli pali kusintha kwa ulusi mu tendon ndi, oponyedwa kupyolera kuzungulira wapadera, ndipo mu nkhani iyi pali kusintha malangizo ake kwa skew lapansi. Ndiye pali kuphatikana ake ku nusu chapamwamba kunja kwa thupi pansipa nsalu mtundu chapamwamba mwachindunji.

Features wa otsika oblique minofu ndi mkati

Koma wosakoma minofu oblique, izo zimachokera m'mphepete lamkati la limene lili m'munsimu zitsulo diso ndipo amawachitira kumalire kunja kwa minofu m'munsi kumbuyo ndi mtundu mwachindunji. Oculomotor minofu kuyandikira apulo, m'pamenenso atazunguliridwa ndi kapisolo ulusi wandiweyani, mwachitsanzo mthunzi chipolopolo, kenako pali kugwirizana awo sclera, koma osati pa mtunda wofanana ku limbus lapansi.

Mwachangu ambiri a ulusi ndi Lamulo la oculomotor mitsempha. Imeneyi, kupatulapo rectus ankaona akunja, kuonetsetsa ake chinkhoswe abducens, ndi oblique aakulu, omwe amaperekedwa ndi zikhumbo mitsempha ku chipika mitsempha. Internal minofu diso ili pafupi limbus, ndipo pamwamba mwachindunji ndi oblique vseredine Ufumuyo limba la masomphenya.

Mbali yaikulu ya innervation - mota mitsempha nthambi oyang'anira thanzi la pang'ono minofu, choncho palibe pazipita molondola pamene kusuntha maso athu.

mbali kandalama a minofu chapamwamba ndipo m'munsi molunjika ndi oblique

Mmene Ufumuyo oculomotor minofu, kudzadalira kayendedwe ka apulo. The mkati ndi kunja ulusi molunjika imakonzedwa horizontally wachibale ndege ya thupi, kotero munthu angathe kuwalimbikitsa horizontally. Minofu awiriwa zikugwira kupereka ofukula apaulendo.

Tsopano tiyeni tione kapangidwe ka minofu diso oblique mtundu. Iwo amatha kuchepetsa choyambitsa zochita zina. Izo zikhoza kugwirizana ndi ena mbali ya malo ndi ubwenzi sclera lapansi. Oblique minofu, amene ali pamwamba, zimathandiza thupi la adatchithisira ndipo zimayenda kunja, ndipo m'munsi - Kukwera komanso akatulutsidwa kunja.

M'pofunika kuganizira mbali ina imagwira chapamwamba ndipo m'munsi molunjika ndi oblique minofu - iwo ndi lamulo kwambiri kwa zikhumbo za mitsempha, pali ntchito bwino mgwirizano pakati minofu minofu ya mwana wa diso, ndipo munthu amatha kuchita kayendedwe lovuta madera osiyana. Choncho anthu mutha kuona chithunzichi atatu azithunzi omwe tikunena, fano khalidwe ndi kuchita bwino, limene anatumizidwa ku ubongo.

minofu wothandiza

Kuwonjezera ulusi izi pa ntchito ndi kuyenda kwa mwana wa m'diso la amatanganidwa ndi zina zimakhala yozungulira diso kudula. Pankhaniyi, zofunika kwambiri imatengedwa minofu zozungulira. Iwo ali dongosolo lapadera, amene akuimira mu magawo angapo - yozungulira, ndi zaka lacrimal.

Choncho, kuchepetsa:

• ophthalmic gawo kumachitika chifukwa kuwongola a makutu yopingasa amene anakonza m'dera kutsogolo, komanso kudzera mwa kutsitsa brows diso ndi kuchepetsa kusiyana ndi;
• gawo yakale kumachitika mwa clamping diso kudula;
• kung'ambikako gawo likuvutika kukula sac lacrimal.

Onse zigawo zitatu, amene minofu zozungulira, zili padziko lonse lapansi. Chiyambi cha ntchito zawo pa mbali medial pamaziko a mafupa. Innervation kumachitika chifukwa nthambi ka mitsempha nkhope. Iwo ayenera kumvetsa kuti chiwerengerocho voteji kapena mtundu uliwonse wa minofu diso zimachitika ntchito misempha.

Other wothandiza minofu minofu

Palinso ulusi sekondale Udindo unitary, multiunitarnye nsalu kuti yosalala mtundu. Multiunitarnye - ndi ciliary minofu minofu ya Iris lapansi. CHIKWANGWANI Unitary ili pafupi ndi mandala, ndi kapangidwe ndi kupezera malawi. Ngati inu kumasuka minofu imeneyi, n'zotheka kusamutsa fano kumtunda diso, ndipo ngati pali kuchepetsa ake, tidzapeza ndi protrusion kwambiri ya mandala, ndi zinthu zimene ali pafupi, mungathe kuwona kwambiri bwino.

mbali zinchito

Ntchito ndi thunthu minofu diso zogwirizana. Kuyambira dongosolo la ataperekedwa kale kulingalira mosamalitsa, tsopano zambiri mwatsatanetsatane yosanthula ntchito ya mtundu wa minofu minofu, popanda munthu sangathe kuzindikira m'dzikoli.

Waukulu zinchito Mbali - luso kupereka zonse zoyenda diso mu madera osiyana :

• Kubweretsa ina kuti pali gulu, mwachitsanzo, kwa mphuno. Mbali imeneyi amaperekedwa mkati chapamwamba patsogolo ndi zina otsika rectus minofu minofu.
• Atigwira, mwachitsanzo pali gulu m'dera mwakanthawi. Mbali imeneyi amaperekedwa ndi mzere lakunja patsogolo chapamwamba ndipo m'munsi oblique minofu zimakhala.
• Kayendedwe m'mwamba ndi chifukwa chamoyo olondola a chapamwamba ndipo m'munsi molunjika oblique mtundu minofu.
• Kunsi kayendedwe ndi chifukwa kugwira ntchito molondola za rectus otsika abwana oblique minofu.

magulu onse zovuta ndi mzake mogwirizana.

akamachita maphunziro

Nthawi iliyonse, kuphwanya kwa diso kayendedwe kumachitika, pamene zizindikiro woyamba wa kupatuka ndi kukaonana ndi katswiri amene ndikatha kumfunsafunsa mosamala angathe mankhwala ndi mankhwala. Nthawi zambiri ndi minofu minofu kudwala inathetsedwa opaleshoni. Kupewa mavuto alionse zikunena, ntchito zonse minofu diso ziyenera kuperekedwa.

zitsanzo

• Chitani 1 - kunja minofu. Kuti asangalale osati minofu minofu, komanso maso, muyenera mofulumira zimaphethira kwa theka miniti. Ndiye kupuma Bwerezani kukambiranako atasinthana maudindowo kachiwiri. Amathandiza pambuyo ntchito ndipo wakhala nthawi yaitali pa kompyuta.
• Chitani 2 - kwa minofu mkati. Pamaso pa mtunda wa 0,3 mamita ayenera kuyikidwa chala mosamala kuyang'ana pa izo masekondi angapo. Ndiye salabadira, koma kupitiriza kuyang'ana pa iye. Ndiye taganizirani pa msonga ya chala chanu masekondi 3-5.
• Chitani 3 - kulimbitsa nsalu zofunika. Thupi ndi mutu ayenera atathana. Maso ayenera kusuntha lamanja ndi lamanzere. Tsogolerani pambali akhale pazipita. Amachita masewera olimbitsa thupi ayenera nthawi zosachepera 9-11.
