Masifunde ngomhlobo wethu (i-Oculomotor Nerve - CN III) osinceda sishukumise amehlo ethu!

Ngaba wakha wazibuza ukuba zingaphi izinto amehlo akho ahambahamba ngazo, phezulu nasezantsi? Xa sifunda incwadi, xa sihamba esitalatweni, xa umntu ethetha, amehlo ethu asebenza ngendlela emangalisayo. Ngoko ke, namhlanje siza kuthetha ngomnye wemithambo-luvo ephambili eshukumisa la mehlo kwaye isinceda sibone ihlabathi. Ifana nomphathi omncinci onika imiyalelo emehlweni ethu.

Yintoni le mithambo-luvo ye-oculomotor?

Ngamafutshane, le mithambo-luvo ye-oculomotor, okanye into esiyibiza ngokuba yiyo ngesiNgesi, yiyo elawula izinto ezininzi ezifana nokuhambisa amehlo akho, ukujonga phezulu, ukujonga ezantsi, nokuphakamisa amehlo akho. Kufana nentambo evela engqondweni yakho exelela izihlunu zamehlo akho ukuba 'zenze oku'.

Nangona eneneni inegama elifana nomthambo omnye, eneneni yimithambo-luvo emibini. Oko kukuthi, enye yeliso lasekunene, enye yeliso lasekhohlo. Le yeyesithathu kwizibini ezili-12 zemithambo-luvo ebizwa ngokuba yi-"Cranial nerves" ezidibana ngqo nengqondo yethu. Yiyo loo nto oogqirha beyibiza ngokuba yi-"CN III" (C.N. Three). Khawucinge ukuba besiya kuphoswa kangakanani ngaphandle kwezi mithambo-luvo zimbini zincinci!

Ngoko ke yintoni umsebenzi oyintloko we-oculomotor nerve?

Kulungile, ngoku masibone ukuba yintoni kanye kanye le 'mphathi' wamehlo ethu ayenzayo. Nangona kukho imithambo-luvo emithathu ebandakanyekayo ekushukumeni kwamehlo, le (i-Oculomotor Nerve) yeyona isebenza kakhulu. Yile ithumela imiqondiso kwizihlunu ezimalunga nesixhenxe ezijikeleze iliso. Jonga into eyenzayo:

• Inceda ukuvula amehlo akho: Oku kukunceda uvule amehlo akho kwangoko xa uvuka kusasa.
• Jika amehlo akho phezulu nasezantsi: Oku kukunceda ukuba ujonge intaka esibhakabhakeni kwaye ubone into ewile phantsi.
• Jikela amehlo omabini ngaphakathi (ngaphakathi): Oku kukwabangela ukuba xa sijonga into ekufutshane nathi, amehlo ethu ajike kancinci ngaphakathi.
• Xa iliso lakho lijonge ngaphakathi, liphakamise: Le yintshukumo enzima kancinci, kodwa ikwanceda.
• Isinceda sibone izinto ezikufutshane nezicacileyo: Oku kwenziwa ngokulawula "isihlunu se-Ciliary" ngaphakathi kwamehlo ethu nokutshintsha imilo yelensi yeliso. Kanye ``ukugxila`` kwikhamera.
• Yandisa umfundi: Oku kukulawula ubungakanani bokukhanya okungena elisweni ngokubangela umfundi ukuba afinyele ekukhanyeni okuqaqambileyo aze akhule ebumnyameni.

Ngoko uyabona, akunjalo? Hayi indlela obaluleke ngayo umsebenzi owenziwa yile ngqondo incinci!

Nangona kunjalo, kukho iintshukumo ezimbini zamehlo ezingalawulwa yile `(Oculomotor Nerve)`. Masifumanise ukuba zeziphi:

• Xa iliso lijikwa lijonge ngaphakathi (lijonge empumlweni), iliso lijikwa lijonge ezantsi. Oku kunceda yi -`(Trochlear nerve)`, i-`CN IV` nerve.
• Ukujika iliso liphume ngaphandle (ngaphandle). Oku kuncediswa yi-"CN VI" nerve, eyaziwa ngokuba yi-"Abducens nerve" .

Zeziphi ezinye izakhono esizifumanayo kule mithambo-luvo?

Umbono wethu yinto enzima kakhulu. Ngoko ke le `(Oculomotor Nerve)` isebenza kunye nezinye iinkqubo ezininzi ukusinika umbono olungileyo. Masibone ukuba zeziphi:

• Indawo yokuhlala: Oku kukukwazi ukugcina umbono ocacileyo wento eza kuwe okanye ehamba kude nawe. Umzekelo, xa ibhola ifika kuwe, ayifiphali ngenxa yale khono.
• IiSaccades: Oku kubhekisa ekushukumeni ngokukhawuleza kwamehlo xa sijonga ngasemva nangaphambili. Kufana nokuskena. Ezi ntshukumo zenzeka naxa sifunda umgca kwincwadi.
• Ukusukelana okutyibilikayo: Ukukwazi ukulandela into ehambayo ngamehlo omabini ngaxeshanye, ngaphandle kokuxhuzula. Umzekelo, oku kusetyenziswa xa ubukele ibhola kumdlalo wekhilikithi.
• I-Vestibulo-ocular reflex: Le yinto entle kakhulu. Nokuba ushukumisa intloko yakho ngokukhawuleza, usenokujonga kwindawo enye ngaphandle kokutshintsha amehlo akho. Kulapho inkqubo elawula ibhalansi yethu kunye neentshukumo zemisipha yentloko namehlo zisebenza kunye.
• I-Pupillary light reflex: Xa ngequbuliso singena kwindawo ekhanyayo okanye emnyama, i-pupil yeliso iya isiba nkulu ngakumbi nangakumbi. Yiyo loo nto ibizwa njalo. Ii-optic nerves zethu (CN II) zixelela ingqondo ukuba ikhanya okanye imnyama apha. Emva koko ingqondo ixelela i-Oculomotor Nerve ukuba itshintshe ubungakanani be-pupil ngokufanelekileyo.

Ziziphi iimeko ezinokuchaphazela i-Oculomotor Nerve?

Njengayo nayiphi na enye imithambo-luvo, i-"Oculomotor Nerve" inokuchaphazeleka zizifo ezahlukeneyo kunye neengxaki. Kwakhona, ekubeni le mithambo-luvo idlula ebuchotsheni, inokonakala ziimpembelelo ezithile ebuchotsheni.

Xa le nerve ingasebenzi kakuhle, siyibiza ngokuba yi -oculomotor nerve palsy . Ngamanye amaxesha ibizwa ngokuba yi-third nerve palsy. Zininzi izizathu ezibangela oku. Makhe sijonge ukuba zeziphi:

• Iingxaki zenkqubo yokujikeleza kwegazi: Iimeko ezifana nesifo seswekile (uhlobo lwesibini lweswekile) kunye noxinzelelo lwegazi oluphezulu zinokubangela ukuba imithambo yegazi ehambisa igazi kwimithambo-luvo ivaleke. Oku kunokukhokelela kwimeko ebizwa ngokuba yi- "ischemia" apho imithambo-luvo ingafumani ioksijini kunye nezondlo ezifunekayo, kwaye imithambo-luvo iqala ukufa. Oku kunokukhokelela ekulahlekelweni kolawulo oluhlala luhleli lwemisipha elawulwa yimithambo-luvo. Kwakhona, ukopha ngaphakathi kwengqondo (ukuvuza kwegazi) kunokubangela ezi meko.
• Ukulimala: Ukulimala okukhulu entloko, ebusweni, okanye engqondweni kunokonakalisa le "Oculomotor Nerve." Emva koko imiqondiso ayidluli kakuhle.
• Iintsholongwane: Iintsholongwane ezifana neebhaktheriya kunye neentsholongwane zinokubangela umonakalo kwimithambo-luvo. Umzekelo , usulelo lwe-HIV kunye neebhaktheriya ezibangela isifo seLyme .
• Izifo zengqondo kunye nenkqubo yemithambo-luvo: Le mithambo-luvo ingachaphazeleka zizifo ezichaphazela ukusebenza kwengqondo. Umzekelo, iimeko ezifana ne -migraines kunye nokuxhuzula . Ingonakaliswa zizifo ezinzulu ezifana ne-stroke kunye nokuhlaselwa kwe-ischemic okuhamba kancinci (ii-TIA) .
• Ukudumba: Ukudumba okubangelwa kukudumba kwezicubu kunokucaphukisa i-Oculomotor Nerve kwaye kuphazamise amandla ayo okudlulisa imiqondiso. Ezi meko zokudumba zinokwenzeka ngezizathu ezahlukeneyo. Zinokubangelwa ziimeko zokuzikhusela komzimba apho inkqubo yethu yokuzikhusela ihlasela izicubu zemithambo-luvo. Umzekelo sisifo esibizwa ngokuba yiMultiple Sclerosis (MS) .
• Iithumba (ezinomhlaza kwaye ezingenabungozi): Iithumba ezifana nezi zinokucinezela kwaye zonakalise i-Oculomotor Nerve, ziphazamise amandla ayo okudlulisa imiqondiso.
• Iimeko zokuzalwa: Ezi ziimeko esizalwa nazo. Ngokwesiqhelo, i-Oculomotor Nerve okanye izakhiwo ezijikeleze yona azikhuli kakuhle. Oku kuphazamisana nokukwazi kwemithambo-luvo ukudlulisa imiqondiso. Ezinye zezi zinokunyangwa.
• Izizathu ze-Idiopathic: Ngamanye amaxesha unobangela wengxaki kwi-Oculomotor Nerve awufumaneki . Xa unobangela ungaziwa, ubizwa ngokuba yi-Idiopathic.

Zithini iimpawu xa le mithambo-luvo ichaphazeleka?

Kulungile, ngoku makhe sibone ukuba zeziphi iimpawu esizifumanayo ukuba kukho ingxaki nge-`(Oculomotor Nerve)`. Ukuba unenye okanye ngaphezulu kwezi, kungcono ukubona ugqirha.

• Ubunzima bokushukumisa iliso elinye okanye omabini.
• Ijwabu eligobileyo (i-Ptosis): Ukuba ijwabu elinye libonakala liphantsi kunelinye.
• I-Strabismus: Xa elinye iliso lijonge ngqo phambili, elinye iliso libonakala ngathi lijike kwelinye icala.
• Umbono ophindwe kabini (iDiplopia): Xa into enye ibonakala ngathi zimbini.
• Umbono ofipheleyo.
• Uxinzelelo lwamehlo kunye nentloko ebuhlungu.
• Ukwanda okungaqhelekanga komfundi (i-mydriasis) kunye nokuncipha okanye ukungabikho kwempendulo ekukhanyeni.

Ukuba unayo nayiphi na kwezi mpawu, musa ukuzityeshela. Kubalulekile ukubona ugqirha wamehlo okanye ugqirha oqhelekileyo ngokukhawuleza ukuze ufumane ingcebiso.

Siyikhusela njani le mithambo-luvo ixabisekileyo?

Ukugcina impilo ye-`(Oculomotor Nerve)` yethu kufana nokugcina impilo yomzimba wonke. Makhe sibone ukuba zeziphi izinto ezilula esinokuzenza:

• Fumana uhlolo lwezonyango lonyaka kunye nokuhlolwa kwamehlo rhoqo:Ezi zinokubonwa ngaphambi kokuba ezinye iimpawu zibonakale emehlweni nasemzimbeni.
• Ukuba usebenzisa iimveliso zecuba (iicuba, i-vaping, icuba lokuhlafuna), yeka ukuzisebenzisa. Okanye, ungaqali. Cela ugqirha wakho akuncede uyeke.
• Sebenzisa izixhobo zokhuseleko ezifana nezigcina-ntloko kunye neebhanti zezihlalo ezimotweni. Ezi zinto zinokunceda ekuthinteleni ukwenzakala entloko.
• Ukuba unezifo ezingapheliyo ezifana nesifo seswekile (uhlobo lwesibini lweswekile) okanye uxinzelelo lwegazi oluphezulu, zilawule kakuhle. Landela imiyalelo kagqirha wakho ngokuchanekileyo.

Okokugqibela, nazi ezona zinto zibalulekileyo ekufuneka uzikhumbule! (Umyalezo Wokuya Ekhaya)

Ngoko ke, mhlawumbi uyaqonda ngoku ukuba le `(Oculomotor Nerve)` yimithambo-luvo ebaluleke kakhulu enceda amehlo ethu asebenze kakuhle kwaye abone ihlabathi ngokucacileyo. Nangona singacingi kakhulu ngayo xa isebenza kakuhle, ukuba kukho ingxaki, inokuba nefuthe elikhulu kubomi bethu.
