Masifunde nge-Abducens Nerve - leyo ikunceda ukuhambisa amehlo akho ukusuka kwelinye icala ukuya kwelinye.

Ngaba wakha wazibuza ukuba amehlo akho ahamba njani kakuhle ukusuka ekunene ukuya ekhohlo? Xa sifunda incwadi, xa sihamba esitalatweni, xa sijonga kwicala elo xa umntu ethetha, amehlo ethu asebenza ngendlela emangalisayo. Ngoko ke, kukho umhlobo omncinci obalulekileyo ngaphakathi entlokweni yethu osincedayo koku. Nguye u-Abducens Nerve . Singathetha ngalo mhlobo namhlanje?

Yintoni i-Abducens Nerve? Ngokuchanekileyo...

Ngamafutshane, i-abducens nerve lilungu elikhethekileyo lenethiwekhi yemithambo-luvo entlokweni yethu. Ngokuchanekileyo, yeyesithandathu kwimithambo-luvo yethu elishumi elinesibini ye-cranial (Cranial Nerve VI - CN VI) . Umsebenzi wayo ophambili kukulawula intshukumo yeliso lethu, oko kukuthi, ukulijika ecaleni. Khawucinge nje, le yimithambo-luvo ekunceda ujike iliso lakho lasekunene liye ngasekunene neliso lakho lasekhohlo liye ngasekhohlo.

Kukho umsipha okhethekileyo ngaphakathi kweliso omncedayo kulo msebenzi, esiwubiza ngokuba yiLateral Rectus Muscle . Ngoko ke lo mthambo weAbducens ufana nomphathi walo msipha.

Imithambo-luvo yiyo edlulisela imiyalezo phakathi kwengqondo yethu kunye nemisipha, akunjalo? Ngoko ke le Abducens Nerve iyafana.

Ayikwenzi oku yodwa. Ezinye ii-nerve ezimbini zinceda amehlo ethu ukuba ahambe ngendlela edibeneyo. Zezi ze-neva yesithathu ye-cranial (Oculomotor Nerve - CN III) kunye ne-neva yesine ye-cranial (Trochlear Nerve - CN IV) . Zidibene, ezi zintathu zilawula iintshukumo zamehlo ethu kakuhle kakhulu.

Imithambo-luvo inemisebenzi emibini ephambili. Eyokuqala kukuva iimvakalelo, ebizwa ngokuba yiSensory Function . Eyesibini kukuhambisa izihlunu, ebizwa ngokuba yiMotor Function . I-Abducens Nerve yethu ayinayo imisebenzi yeemvakalelo. Yenza umsebenzi we-motor kuphela. Oko kukuthi, umsebenzi wayo kuphela kukujonga iliso ngaphandle.

Ngoko ke, yintoni kanye kanye umsebenzi we-Abducens Nerve?

Njengoko besitshilo ngaphambili, i-abducens nerve yiyo ejika amehlo ethu aye ngaphandle, oko kukuthi, ecaleni, kwaye i-lateral rectus muscle yiyo ehambisa iliso lakho lasekunene liye ngasekunene neliso lakho lasekhohlo liye ngasekhohlo. Le nerve ikwasebenza nezinye izihlunu ukujika omabini amehlo aye ngasekunene okanye ngasekhohlo ngaxeshanye.

Khawuthelekelele, ufunda esi sivakalisi ngoku. Amehlo akho ahamba kancinci ukusuka ekhohlo ukuya ekunene. Ngelo xesha, usebenzisa le Abducens Nerve kunye neLateral Rectus Muscle.

Masithathe omnye umzekelo. Khawucinge ukuba ukwipaki entle. Ngequbuliso, uva intaka ikhala emthini ngasekunene kwakho. Wakuba ujika ujonge ngaloo ndlela, i-abducens nerve yakho ixelela izihlunu ezingaphambili kweliso lakho, "Kulungile, jonga ngasekunene." Emva koko ungayibona loo ntaka intle. Ngaba uyayiqonda intsingiselo yoko?

Iphi i-Abducens Nerve emzimbeni wethu?

Lo ngumthambo omncinci kakhulu, ongaphakathi entlokweni yethu, ngasemva nje kwamehlo ethu. Umile okwesebe lomthi.

Sinee-Abducens Nerves ezimbini ezinjalo, enye yeliso lasekhohlo nenye yeliso lasekunene. Ezi nerves zihamba ukusuka kwi-brainstem yethu (inxalenye yengqondo engasemva kwengqondo edibanisa nomqolo) ukuya kwi-Lateral Rectus Muscle ngaphakathi kwesokhethi yeliso. Kolu hambo, kufuneka zidlule kwindawo engaphantsi kwe-subarachnoid , kwi-dura mater , kunye nomngxuma omncinci kwi-skull ukuze zingene kwisokhethi yeliso.

Ubusazi? Kwimithambo-luvo engaphakathi kwengqondo yethu, i-Abducens Nerve inendlela yesibini ende emva kwe-Vagus Nerve.

Ngoko ke, yintoni iAbducens Nucleus?

Eli libali elinzulu kancinci, kodwa ukuze lichazwe ngokulula, i-Abducens Nucleus ifana "neziko lomyalelo" wale nerve. Ifana ne-CPU yekhompyutha. Yile nucleus exelela i-nerve into emayenziwe. Nangona le nerve isuka kwi-brainstem ukuya kwi-eye socket, le nucleus ikwinxalenye yengqondo ebizwa ngokuba yi-Pons . Ii-Pons zikwindawo ephezulu, ngasemva kwengqondo yethu. Oko kuthetha ukuba ingaphantsi kwe-Midbrain nangaphezulu kwe-Medulla Oblongata (le yindawo ngaphambi kokuba idibane nomqolo).

Ngaba kukho imeko eqhelekileyo echaphazela i-Abducens Nerve?

Ewe, ngelishwa, kukho iingxaki ezinokuchaphazela le mithambo-luvo. Eyona ixhaphakileyo kwezi yi- Abducens Nerve Palsy , okanye i-Sixth Nerve Palsy . Kulapho imithambo-luvo yonakele khona, nto leyo ebangela ukuba iLateral Rectus Muscle ibe buthathaka kwaye ngamanye amaxesha ingasebenzi kakuhle .

Kukho izizathu ezininzi zoku:

• Isifo seswekile
• Igazi elonyukayo
• Ukulimala entloko
• Istroke
• Ezinye izizathu ezahlukeneyo

Eyona nto ibalulekileyo kukubona ugqirha ngokukhawuleza ukuba ufumana naziphi na ezi mpawu ukuze ufumane unobangela .

Kuthiwa le mithambo-luvo isengozini enkulu yokonakala kuba ihamba umgama omde ukusuka kwelinye icala lobuchopho ukuya kwelinye. Ngenxa yobude bayo, isengozini enkulu yokwenzakala.

Zithini iimpawu zengxaki nge-Abducens Nerve?

Khawucinge ukuba imithambo-luvo yakho ye-abducens yonakele. Emva koko umsipha ojika iliso liye ngaphandle awufumani imiyalezo evela ebuchotsheni ngokufanelekileyo. Ngenxa yoko, unokufumana iimpawu ezifana nezi:

• Ubunzima okanye ukungakwazi ukujika iliso (amehlo) ngasekhohlo nasekunene.
• Ukubona kabini (iDiplopia) - Oku kulapho ubona izinto ezimbini ngaxeshanye. Oku kunokubonakala ngakumbi xa ujonge ngaphandle kweliso elichaphazelekayo.
• Ukungalingani kwamehlo - Xa elinye iliso lijonge ngqo phambili, elinye iliso lisenokubonakala ngathi litsalelwe ngaphakathi.
• Uxinzelelo lwamehlo okanye intlungu.

Ukuba nawe uvakalelwa yinto efana nale, musa ukuyityeshela, kulungile?

Ungayijonga njani impilo ye-Abducens Nerve yakho?

Ugqirha okanye ingcali yamehlo iza kujonga impilo yale nerve. Bangasebenzisa iimvavanyo ezifana nezi:

• Ukuhlolwa kwamehlo: Ugqirha uza kujonga umbono wakho aze akucele ukuba uhambise amehlo akho kumacala ahlukeneyo ukuze abone ukuba zeziphi iintshukumo onokuzenza kunye nokuba zeziphi ezinzima.
• Uvavanyo lwegazi: Ngamanye amaxesha uvavanyo lwegazi lunokwenziwa ukuze kufunyanwe unobangela weempawu, umzekelo, ukujonga imeko efana nesifo seswekile.
• Uvavanyo lwemifanekiso: Uvavanyo oluqhelekileyo lwemifanekiso olusetyenziswa ukujonga i-abducens nerve yiMagnetic Resonance Imaging (MRI) . I-MRI ivumela ugqirha wakho ukuba abone ngokucacileyo imithambo-luvo kunye nezicubu ezingaphakathi kwentloko yakho.

Ziziphi iindlela zonyango lweengxaki zemithambo-luvo ze-Abducens?

Nje ukuba ugqirha wakho afumanise ukuba kukho into ebangela iimpawu zakho, uza kunyanga i-abducens nerve eyonakeleyo. Unyango lunokuquka:

• Ukunyanga okanye ukulawula imeko ebangela iimpawu. Umzekelo, ukuba ingxaki ibangelwa sisifo seswekile, ukulawula isifo seswekile yeyona nto ibalulekileyo.
• Ukunxiba i-eye patch okanye iilensi zokulungisa kunokunceda ekunciphiseni ukubona kabini.
• Iinaliti zeBotulinum Toxin. Ngamanye amaxesha ziyasetyenziswa.
• Utyando. Utyando lunokufuneka ukuba ezinye iindlela zonyango aziphumeleli okanye kwiimeko ezithile ezikhethekileyo.

Khumbula, unyango olufumanayo lunokwahluka kumntu nomntu kuxhomekeke kwisizathu seempawu zakho, ngoko ke kubalulekile ukulandela imiyalelo kagqirha wakho ngokuchanekileyo.

Ndingayinyamekela njani i-Abducens Neves yam?

Enyanisweni, ukunyamekela imithambo-luvo yakho kukunyamekela umzimba wakho wonke. Imithambo-luvo yinxalenye yothungelwano olukhulu lonxibelelwano phakathi kwengqondo kunye nemisipha yethu. Ngoko ke, qiniseka ukuba utya ukutya okunempilo, uzilolonge rhoqo, kwaye ufumane unyango lwazo naziphi na iimeko ezingaphantsi.Ngelixa unyamekela impilo yakho iyonke, ukhathalela nemithambo-luvo yakho.

Ukuzikhusela ekulimaleni entloko kubalulekile ukukhusela le mithambo-luvo. Njengoko besitshilo, le mithambo-luvo inde kancinci, ngoko ke inokuba sengozini yokwenzakala.

Ukuba ufuna ukwazi okungakumbi ngempilo yakho iyonke okanye impilo yemithambo-luvo, ungoyiki ukubuza ugqirha wakho.

Okokugqibela, izinto ekufuneka uzikhumbule

Nangona ufunda esi sivakalisi, i-abducens nerve yakho iyasebenza ngaphandle kokuba wena uqonde. Sisenokungaqondi ukuba ibaluleke kangakanani kubomi bethu bemihla ngemihla. Kodwa lo mhlobo mncinci osinceda sijonge ekhohlo nasekunene yi-nerve enkulu esuka kwelinye icala lobuchopho iye kwelinye. Yiyo loo nto isengozini enkulu yokonakala.

Ungayikhusela imithambo-luvo yakho ngokunyamekela umzimba wakho nangokulumka ukuze uphephe iingozi. Ukuba unemibuzo engaphezulu malunga nale mithambo-luvo, thetha nogqirha. Ukunyamekela umzimba wakho yeyona nto ilungileyo onokuyenza kuqala!
