Ese wigeze wibaza uburyo amaso yacu agenda vuba kandi neza iyo dusoma igitabo, tureba imodoka mu muhanda, cyangwa tuvugana n'umuntu? Ibi byose bibaho nk'ubumaji, tutanabizi. Rero intwari nyamukuru iri inyuma y'iki gikorwa gitangaje ni umutsi wa oculomotor, cyangwa icyo mu buvuzi twita `(Oculomotor Neurve)`. Iyi ni iya gatatu mu mitsi 12 y'ingenzi ifitanye isano n'ubwonko bwacu. Niyo mpamvu tuyita `(CN III)`.
None se akazi k'umutsi wa oculomotor ni akahe?
Mu magambo make, uyu mutsi ugenzura imitsi irindwi ikikije amaso yawe. Nubwo hari imitsi itatu y'ingenzi igira uruhare mu mikorere y'amaso, uyu ni wo ukora akazi kenshi. Ni nk'umuyobozi mukuru mu biro.
Tekereza, amaso yawe ni kamera ebyiri ziri mu mubiri wawe. Izi kamera ebyiri zigomba guhindurwa, gupimwa, no guhindurwa hakurikijwe urumuri. Utubuto twose tujyanye n'icyo gikorwa turi hafi y'uyu mutsi.
Reka turebe imbonerahamwe iri hepfo kugira ngo turebe neza icyo uyu mutsi uhura na cyo.
| Imikorere y'ingenzi | Ibisobanuro byoroshye |
|---|---|
| Kuzamura amaso | Ufungura amaso yawe mu gitondo kandi ukayafungura umunsi wose kubera ibimenyetso biva muri uyu mutsi. |
| Gutembagara amaso hejuru no hasi | Ibi nibyo bigufasha kureba indege iri mu kirere no kureba ikintu cyaguye hasi. |
| Gutembagaza amaso yerekeza ku mazuru | Iyo isazi iguguye ku mazuru, uyu mutsi ureba imbere. |
| Igenzura ry'abanyeshuri | Ni ubwo bucucike bugabanuka iyo bushyizwe ku zuba ryinshi kugira ngo bugabanye urumuri rugera mu jisho, kandi bugakura mu mwijima kugira ngo bubone urumuri rwinshi. |
| Kwibanda ku kintu runaka ugenzura indorerwamo y'ijisho | Iyo urebye ikintu kiri kure hanyuma ugahita ugerageza gusoma igitabo kiri hafi, uyu mutsi uhindura imiterere y'indorerwamo y'ijisho ku buryo ushobora kubona neza intera zombi. |
Ariko ibuka ko uyu mutsi atari wo wonyine ugenzura imikorere yose y'amaso. Hari indi mitsi ibiri ifasha mu mirimo ibiri mito. Ni `(Trochlear nerve / CN IV)`, ifasha ijisho guhindukira imbere no kureba hasi, na `(Abducens nerve / CN VI)`, ifasha ijisho guhindukira inyuma (imbere) .
Ubushobozi bwihariye usibye gukora imyitozo ngororamubiri y'amaso
Uyu mutsi, hamwe n'izindi sisitemu nyinshi, bidufasha gukora ibintu byinshi neza.
- Icumbi: Tekereza umuntu arimo kugutera umupira. Ni ukubera imikorere y'uyu mutsi bituma ukomeza kubona neza umupira, utarimo kuba mwiza uko wegereza.
- Gupima amaso (Saccades): Iyi ni ingendo zihuse zimura amaso yawe kuva ku ijambo rimwe kugeza ku rindi, umurongo ujya ku wundi, iyo usoma ikinyamakuru cyangwa igitabo. Ni kimwe kandi n'iyo ureba abantu mu cyumba rimwe na rimwe.
- Gukurikira mu buryo bworoshye: Ubu bushobozi bugufasha gukurikirana imodoka mu muhanda cyangwa inyoni mu kirere nta kibazo utayikuyemo amaso.
- Vestibulo-ocular reflex: Ibi bigufasha kugumana amaso yawe ahamye nubwo wahindukiza umutwe wawe vuba ibumoso cyangwa iburyo. Bikorana na sisitemu igenzura kuringaniza kwawe.
- Umucyo w’ijisho: Uyu mutsi ugenzura inzira imboni y’ijisho ikora iyo urumuri rwinshi rukubise mu jisho, kandi ikongera kwiyongera iyo urumuri rugabanutse.
Ni izihe ndwara zishobora kugira ingaruka kuri uyu mutsi?
Kimwe n'indi mitsi yose mu mubiri wacu, umutsi wa oculomotor ushobora kwangirika bitewe n'indwara zitandukanye n'impanuka. Indwara iyi mitsi idakora neza yitwa "Oculomotor nerve palsy." Dore zimwe mu mpamvu zishobora gutera.
| Impamvu ishoboka | Ni iki kiri kuba? |
|---|---|
| Ibibazo by'imitsi inyuranamo amaraso | Cyane cyane diyabete idacunzwe neza n'umuvuduko ukabije w'amaraso bishobora kugabanya amaraso anyura mu mitsi. Iyi ndwara yitwa "ischemia." Ibi bishobora kwangiza imitsi no gutuma imitsi ikora nabi. |
| Ibikomere ku mutwe no mu maso | Gukomereka ku mutwe cyangwa agace gakikije ijisho bivuye ku mpanuka bishobora kwangiza uyu mutsi mu buryo butaziguye. |
| Indwara zandurira mu mubiri | Zimwe mu ndwara za bagiteri na virusi, nk'indwara ya Lyme, zishobora guhungabanya imikorere y'imitsi. |
| Indwara z'ubwonko n'iz'imitsi | Uyu mutsi ushobora kandi kwibasirwa n'indwara zigira ingaruka ku mikorere y'ubwonko, nko gucika intege mu bwonko , migraine, no gucika intege. |
| Ububyimbirwe | Hari indwara zimwe na zimwe zitera ubudahangarwa bw’umubiri zishobora gutuma ingirangingo zikikije imitsi zibyimba, nka sclerosis nyinshi (MS). Uku kubyimba gushobora kwangiza imitsi no kubangamira imikorere yayo. |
| Ibibyimba | Uyu mutsi ushobora gukandamizwa no kwangirika bitewe n'ibibyimba cyangwa ibibyimba bisanzwe mu bwonko. |
| Indwara z'ababyeyi | Ni gake cyane, ibibazo bishobora kubaho igihe umwana avuka bitewe n'uko imitsi cyangwa imiterere yayo idakura neza. |
Wamenya ute niba hari ikibazo kuri uyu mutsi? (Ibimenyetso)
Iyo hari intege nke cyangwa kwangirika k'umutsi wa oculomotor, ushobora kugira kimwe cyangwa byinshi muri ibi bikurikira. Ibi bishobora gutangira mu buryo butunguranye.
- Kugwa kw'amaso y'ijisho (ptosis): Indwara aho ijisho rimwe ridashobora gufungura neza kandi rikagaragara nk'aho riguye hasi.
- Strabismus: Indwara aho ijisho rimwe rihindukirira mu cyerekezo gitandukanye, amaso yombi adashobora kwerekeza mu cyerekezo kimwe .
- Kubona ibintu bibiri (diplopia): Kubona ikintu kimwe nk'ibiri.
- Kubona ibintu mu buryo butari bwo: Kubona ibintu neza, kubona ibintu mu buryo butari bwo.
- Kubabara amaso no kuribwa umutwe: Kuribwa umutwe bishobora guterwa n'umuvuduko w'inyongera ku maso.
- Mydriasis: Iso ry'ijisho rimwe ni rinini kurusha irindi kandi ntiryitabira urumuri cyangwa ngo ribyitabire buhoro cyane.
Niba ugize ibimenyetso nk'ibi mu buryo butunguranye, cyane cyane niba ufite umutwe ukomeye hamwe no kubona ibintu bibiri, amaso arembye, n'ibindi, bishobora kuba byihutirwa. Muri icyo gihe, ugomba kujya kwa ETU (Ishami rishinzwe Ubuvuzi bwihutirwa) vuba bishoboka.
Ni iki twakora kugira ngo twirinde ubwo bwoko bw'indwara z'imitsi?
Nk’uko twita ku mubiri wacu wose, tugomba no gutekereza ku buzima bw’uyu mutsi. Ni ingenzi cyane gukurikiza ibi bintu.
- Jya kwisuzumisha kwa muganga no gupimwa amaso buri mwaka. Ibi bishobora gufasha kumenya ibibazo byinshi mbere yuko ibimenyetso bigaragara.
- Irinde kunywa itabi, guhekenya itabi, nibindi byose. Niba usanzwe ubikoresha, saba muganga wawe ubufasha kugira ngo ubireke.
- Irinde gukomereka mu mutwe. Ambara ingofero iyo utwaye amagare na moto. Ambara umukandara w'imodoka iyo utwaye imodoka.
- Niba ufite indwara zidakira nka diyabete cyangwa umuvuduko ukabije w'amaraso, zigenzure neza. Fata umuti wanditswe na muganga ku gihe. Kurikiza amabwiriza nk'uko yatanzwe.
Amaherezo, iyi mitsi ya oculomotor ni igice cy'ingenzi cyane gifasha mu buryo bucece hafi ya byose dukora buri munsi. Niba ubonye impinduka mu mikorere yayo, icyiza wakora si ugutinya cyangwa guhangayika, ahubwo ni ukugisha inama kwa muganga.
Ubutumwa bwo kujyana mu rugo
- Umutsi wa oculomotor ni wo mutsi mukuru ugenzura ingendo nyinshi z'amaso, kuzamura amaso, n'ingano y'ijisho ry'umukara.
- Indwara zisanzwe nka diyabete idagenzurwa neza n'umuvuduko ukabije w'amaraso bishobora kwangiza uyu mutsi.
- Niba ubonye ibimenyetso nko kunama kw'amaso, kureba ibintu bibiri (kubona ibintu bibiri), cyangwa kugorana guhindukiza ijisho rimwe, ni ngombwa guhita ubonana na muganga.
- Dukurikije imibereho myiza no gucunga neza indwara zidakira, dushobora kurinda uturemangingo tw’imitsi yacu yose, harimo n’uyu mutsi.
