Iqhawe elincinci elikunceda ujonge phantsi: Masifunde ngeTrochlear Nerve!

Ngaba wakha wazibuza ukuba amehlo ethu ajika lula njani xa sihamba ngezinyuko, sijonga ukutya etafileni, okanye sifunda into ethile kwifowuni yethu? Sihlala senza ezi zinto, kodwa asicingi ngenkqubo emangalisayo esemva kwayo, akunjalo? Enyanisweni, 'intambo' encinci, kodwa ebaluleke kakhulu evela kwingqondo yethu, i-nerve, iyasinceda kulo msebenzi. Namhlanje siza kuthetha ngale qhawe lincinci, i-nerve ye-trochlear.

Yintoni le Trochlear Nerve?

Ngamafutshane, i-trochlear nerve yi-nerve ethwala imiqondiso esuka kwingqondo yakho ukuya kwisihlunu esithile esisesweni lakho. Ngokwenyani, yi-motor nerve. Oku kuthetha ukuba ayithwali ulwazi lweemvakalelo ukuya engqondweni, kodwa ithwala umyalezo ovela kwingqondo ukuya kwindawo efanelekileyo yokuhamba. Njengokuba umbane ohamba ukusuka kwiswitshi ukuya kwisibane esisendlwini yethu udlula kwintambo.

Kukho iiperi ezili-12 zezi nerve ziphambili ngaphakathi entlokweni yethu. Ezi nerve sizibiza ngokuba yi-cranial nerve. Eyesine kwezi nerve yi-trochlear nerve. Yiyo loo nto ikwabizwa ngokuba yi-cranial nerve yesine , kwaye oogqirha bayibiza ngokuba yi-CN IV . Sinezi nerve ezimbini, enye yeliso lasekunene kwaye enye yeliso lasekhohlo. Zombini zinomsebenzi ofanayo.

Yintoni kanye kanye eyenzekayo kule mithambo-luvo?

I-trochlear nerve inomsebenzi omnye oyintloko. Oko kukuthumela imiqondiso kwimisipha ethe tyaba engaphezulu kwamehlo ethu ukuze ishukume. Le mithambo kunye nale misipha zisebenza kunye ukuze zisivumele ukuba:

• Jonga ezantsi: Khawuthelekelele ujonge ezantsi ngelixa uhamba esitratweni, uhla ngezinyuko, okanye ujonge ezantsi kwisitya sakho ngelixa usitya. Ezi zinto zimbini xa zidibene zezona zenza amehlo akho ajonge ezantsi ngalo lonke ixesha.
• Jikela amehlo akho ngaphakathi: Oku kunceda ekujikeni amehlo akho ngaphakathi.
• Jika amehlo abheke ngaphandle: Oku kukwanceda ekujikeni amehlo abheke ngaphandle nangaphandle.

Kukho nezinye imithambo-luvo ezinceda ekushukumiseni amehlo. Kulungile ukuzikhumbula nazo:

• I-Oculomotor nerve (CN III)
• I-Abducens nerve (CN VI)
• I-Facial nerve (CN VII) - Oku kunceda kakhulu ekuvaleni iinkophe.

Iphi le mithambo-luvo ingaphakathi kwentloko yethu?

Nangona le mithambo-luvo ilawula isihlunu esinye kuphela, uhambo oluvela ekufumaneni eso sihlunu ukuya kwesi sixhobo lude kancinci. Lufana nomhambi ohamba uhambo olude. Olu hambo luqala kwisiseko sethu sengqondo. Ukusuka apho, ludlula kwiindawo ezine eziphambili de lufikelele elisweni.

1. I-Trochlear nucleus: Le yindawo yokuqala ye-nerve. Oko kukuthi, indawo ekufutshane nobuchopho. Ikwindawo ephezulu ye-brainstem.

2. I-Ambient tankner: Le nerve idlula kufutshane nee-membranes ezikhuselayo (i-meninges) ezijikeleze ubuchopho. Le nxalenye ibizwa ngokuba yile.

3. I-Cavernous sinus: Le yindawo efana nomngxuma ophakathi kwentloko yethu. I-nerve nayo idlula apha.

4. I-Orbit: Ekugqibeleni, iliso lingena kwi-orbital cavity, i-boney cavity ye-skull apho iliso likhoyo. Kulapho i-nerve iqhagamshela khona kwindawo eya kuyo, i-superior oblique muscle.

Kwenzeka ntoni ukuba umthambo we-trochlear wonakele?

Ukuba le mithambo-luvo yonakele, ichaphazela ngqo intshukumo yamehlo akho kunye nokubona kwakho. Oogqirha bayibiza le meko ngokuthi yi-fourth nerve palsy okanye yi-trochlear nerve palsy. Kukho iimpawu ezininzi eziqhelekileyo zale meko.

Zithini izizathu zomonakalo kule mithambo-luvo?

I-trochlear nerve inomzila omde odlula ekhayeni, nto leyo eyenza ukuba ibe sesichengeni sokwenzakala kunezinye ii-cranial nerve, ingakumbi ngenxa yokwenzakala entloko .

• Iingozi zezithuthi (ingakumbi iingozi zeebhayisekile)
• Imidlalo efana nebhokisi
• Ukuwa

Ngamanye amaxesha, ngendlela engenakucingelwa, nokuba kukubetheka kancinci entloko kunokonakalisa le mithambo-luvo.

Kukho ezinye izizathu ezingaqhelekanga:

• Izifo ze -Microvascular , ingakumbi iimeko ezibangelwa zizifo ezifana nesifo seswekile.
• Ukucinezelwa kwemithambo-luvo ngenxa yomhlaza wobuchopho okhula kufutshane nemithambo-luvo.
• Uxinzelelo oluphezulu lwe-intracranial.

Abanye abantwana bazalwa benengxaki yale nerve. Ibizwa ngokuba yi-congenital fourth nerve palsy.

Sizigcina njani imithambo-luvo yethu isempilweni?

Asinakuyithintela ngokwenene into efana nezizathu zokuzalwa. Nangona kunjalo, singenza lukhulu ngokuphepha ukwenzakala entloko nokunyamekela impilo yenkqubo yemithambo-luvo ngokubanzi.

Masithintele ukwenzakala entloko!

• Yenza imeko-bume yekhaya lakho ikhuseleke: Ukuba unomntwana omncinci ekhayeni lakho, qaphela iindawo apho anokuwa khona aze abethe intloko yakhe. Ukuba unomntu omdala, cinga ngakumbi ngeendawo apho anokutyibilika aze awe khona (umz., igumbi lokuhlambela).
• Iibhanti zezihlalo kunye nezigcina-ntloko: Nxiba iibhanti zezihlalo rhoqo xa ukhwela imoto. Thutha abantwana kwisihlalo semoto esifanelekileyo. Kuyimfuneko ukunxiba isigcina-ntloko esisemgangathweni omiselweyo xa ukhwela ibhayisekile okanye imotombayisekile.
• Ukhuseleko xa udlala imidlalo: Nxiba izixhobo zokuzikhusela ezifanelekileyo xa udlala imidlalo efana neragbi kunye nebhokisi.

Gcina inkqubo yemithambo-luvo iphilile ngokubanzi

• Ukutya okunesondlo: iVithamini D kunye neVithamini B12 ukuze kubekho inkqubo yemithambo-luvo esempilweniKubaluleke kakhulu. Ngoko ke, yongeza ukutya okuqulethe ezi zinto (intlanzi, amaqanda, ubisi, imifuno) ekutyeni kwakho.
• Ulawulo lwezifo ezingapheliyo: Isifo seswekile kunye noxinzelelo lwegazi oluphezulu zizifo ezimbini eziphambili ezinokonakalisa imithambo-luvo. Ukuba unazo ezi zifo, landela imiyalelo kagqirha wakho kwaye uzilawule kakuhle.
• Yeka ukutshaya: Ukutshaya kunciphisa ukuhamba kwegazi ukuya kwimithambo-luvo. Ngoko ke funa uncedo lokuyeka ukutshaya.
• Gcina ubunzima obusempilweni: Ukugcina ubunzima obusempilweni obufanele umzimba wakho kubaluleke kakhulu kwimpilo iyonke.
• Nciphisa uxinzelelo: Izinto ezifana nokucamngca, ukuhamba, kunye neyoga zinokunceda ekunciphiseni uxinzelelo.

Ndifanele ndimbone nini ugqirha?

Ugqirha wakho uza kukuhlola aze, ukuba kuyimfuneko, akuthumele kwingcali yamehlo okanye kwingcali yemithambo-luvo. Baza kukwenza uvavanyo olufunekayo baze bakuchazele ukuba yintoni ebangela oku kunye nento omawuyenze.

Hlala ukhumbula, nokuba yinxalenye encinci yomzimba wethu inendima ebaluleke kakhulu. I-trochlear nerve nayo ayifani. Kungoko ke, kubaluleke kakhulu ukunyamekela imizimba yethu nokunika ingqalelo kwiimpawu ezisinika zona.
