Ake sifunde nge-Abducens Nerve - leyo ekusiza ukuthi uhambise amehlo akho kusukela kolunye uhlangothi kuya kolunye.

Wake wazibuza ukuthi amehlo akho ahamba kanjani kahle kusukela kwesokudla kuya kwesobunxele? Uma sifunda incwadi, uma sihamba emgwaqweni, uma sibheka kuleyo ndlela lapho othile ekhuluma, amehlo ethu asebenza ngendlela emangalisayo kakhulu. Ngakho-ke, kukhona umngane omncane obaluleke kakhulu ngaphakathi kwekhanda lethu osisiza ngalokhu. Ungu -Abducens Nerve . Ingabe singakhuluma ngalomngane namuhla?

Iyini i-Abducens Nerve? Ukucacisa...

Kalula nje, i-abducens nerve iyilungu elikhethekile kakhulu lenethiwekhi yezinzwa ekhanda lethu. Ukuze sibe neqiniso, ingeyesithupha kweziyishumi nambili zemizwa yethu ye-cranial (Cranial Nerve VI - CN VI) . Umsebenzi wayo oyinhloko ukulawula ukunyakaza kwamehlo ethu, okungukuthi, ukuyiphendulela eceleni. Cabanga nje, lena yimizwa ekusiza ukuthi uphendule iso lakho lokunene liye kwesokudla kanye neso lakho lesobunxele liye kwesobunxele.

Kukhona umsipha okhethekile ngaphakathi kweso ukuze umsize ngalo msebenzi, esiwubiza ngokuthi i-Lateral Rectus Muscle . Ngakho-ke lo msipha we-Abducens ufana nomlawuli walo msipha.

Imizwa yiyo edlulisa imiyalezo phakathi kobuchopho bethu nemisipha, akunjalo? Ngakho-ke le Abducens Nerve iyafana.

Akukwenzi lokhu kodwa. Ezinye izinzwa ezimbili zisiza amehlo ethu ukuthi ahambe ngendlela ehlelekile. Ziyi -nerve yesithathu ye-cranial (i-Oculomotor Nerve - CN III) kanye ne-nerve yesine ye-cranial (i-Trochlear Nerve - CN IV) . Ndawonye, ​​lezi zintathu zilawula ukunyakaza kwamehlo ethu kahle kakhulu.

Imizwa inemisebenzi emibili eyinhloko. Omunye ukuzwa imizwa, ebizwa ngokuthi Umsebenzi Wezinzwa . Omunye ukuhambisa imisipha, ebizwa ngokuthi Umsebenzi Wezinzwa . Imizwa yethu ye-Abducens ayinawo umsebenzi wezinzwa. Yenza umsebenzi we-motor kuphela. Okusho ukuthi, umsebenzi wayo kuphela ukubhekisa iso ngaphandle.

Ngakho-ke, uyini ngempela umsebenzi we-Abducens Nerve?

Njengoba sishilo ngaphambili, i-abducens nerve yiyo ephendula amehlo ethu ngaphandle, okungukuthi, ohlangothini, kanti imisipha ye-lateral rectus yiyo ehambisa iso lakho lokunene ngakwesokudla kanye neso lakho lesobunxele ngakwesokunxele. Le nzwa isebenza neminye imisipha ukuphendulela womabili amehlo ngakwesokudla noma kwesobunxele ngesikhathi esisodwa.

Cabanga nje, ufunda lo musho njengamanje. Amehlo akho ahamba kancane ukusuka kwesobunxele kuya kwesokudla. Ngaleso sikhathi, usebenzisa lo mthambo we-Abducens kanye ne-Lateral Rectus Muscle.

Ake sithathe esinye isibonelo. Ake uzicabange usepaki elihle. Kungazelelwe, uzwa inyoni ikhala esihlahleni ngakwesokudla sakho. Lapho nje uphenduka ukuze ubheke ngaleyo ndlela, i-abducens nerve yakho itshela imisipha engaphambili kweso lakho ukuthi, "Kulungile, bheka ngakwesokudla." Bese ungayibona leyo nyoni enhle. Uyakuqonda ukubaluleka kwalokho?

Ikuphi i-Abducens Nerve emizimbeni yethu?

Lona umthambo omncane kakhulu, otholakala ngaphakathi kwekhanda lethu, ngemuva nje kwamehlo ethu. Ume njengegatsha lomuthi.

Sinezinzwa ezimbili ezinjalo ze-Abducens, enye yeso lesobunxele kanye nenye yeso lesokudla. Lezi zinzwa zisuka esiqwini sethu sobuchopho (ingxenye yobuchopho engemuva kobuchopho exhumanisa nomgogodla) kuze kufike ku-Lateral Rectus Muscle ngaphakathi kwesokhethi. Kulolu hambo, kufanele zidlule esikhaleni se-subarachnoid , i-dura mater , kanye nomgodi omncane okhakhayini ukuze zingene esokhethini leso.

Ubuwazi? Emizweni esebuchosheni bethu, i-Abducens Nerve inendlela yesibili ende kakhulu ngemva kwe-Vagus Nerve.

Ngakho-ke, iyini i-Abducens Nucleus?

Lena indaba ejulile kancane, kodwa uma siyibeka kalula, i-Abducens Nucleus ifana "nesikhungo somyalo" sale nerve. Ifana ne-CPU yekhompyutha. Yile nucleus etshela i-nerve ukuthi yenzeni. Nakuba le nerve isuka esiqwini sobuchopho iye esisekelweni seso, le nucleus itholakala engxenyeni yobuchopho ebizwa ngokuthi i-Pons . Ama-Pons atholakala phezulu, ngemuva kobuchopho bethu. Lokho kusho ukuthi ingaphansi kwe-Midbrain kanye nengaphezulu kwe-Medulla Oblongata (lena yingxenye ngaphambi kokuba ixhumeke emgogodleni).

Ingabe kukhona isimo esivamile esithinta i-Abducens Nerve?

Yebo, ngeshwa, kunezinkinga ezingathinta lo mthambo. Ovame ​​kakhulu kulezi yi- Abducens Nerve Palsy , noma i-Sixth Nerve Palsy . Lokhu kwenzeka lapho umthambo wonakala, okwenza i-Lateral Rectus Muscle ibe buthakathaka futhi ngezinye izikhathi ikhubazeke .

Kungaba nezizathu eziningi zalokhu:

• Isifo sikashukela
• Umfutho wegazi ophakeme
• Ukulimala ekhanda
• Isifo sohlangothi
• Ezinye izizathu ezahlukahlukene

Into ebaluleke kakhulu ukubona udokotela ngokushesha uma uhlangabezana nanoma yiziphi zalezi zimpawu ukuze uthole imbangela .

Kuthiwa futhi le nzwa isengozini enkulu yokulimala ngoba ihamba ibanga elide isuka komunye umkhawulo wobuchopho iye komunye. Ngenxa yobude bayo, isengozini enkulu yokulimala.

Yiziphi izimpawu zenkinga nge-Abducens Nerve?

Cabanga ukuthi i-abducens nerve yakho yonakele. Khona-ke imisipha ephendula iso ngaphandle ayitholi imiyalezo evela ebuchosheni ngendlela efanele. Ngenxa yalokho, ungase ube nezimpawu ezifana nalezi:

• Ubunzima noma ukungakwazi ukujika iso/amehlo ngakwesobunxele kanye/noma kwesokudla.
• Ukubona okukabili (i-Diplopia) - Lokhu kwenzeka lapho ubona izinto ezimbili ngesikhathi esisodwa. Lokhu kungase kubonakale kakhulu uma ubheka iso elithintekile.
• Ukungalungi kahle kwamehlo - Uma iso elilodwa libheke phambili, elinye iso lingase libonakale sengathi lidonseleke ngaphakathi.
• Ubuhlungu noma ukukhandleka kwamehlo.

Uma nawe uzizwa into efana nale, ungayizibi, kulungile?

Ungayihlola kanjani impilo ye-Abducens Nerve yakho?

Udokotela noma udokotela wamehlo uzohlola impilo yale nerve. Bangasebenzisa izivivinyo ezifana nalezi:

• Ukuhlolwa kwamehlo: Udokotela uzohlola umbono wakho bese ekucela ukuthi uhambise amehlo akho ngezindlela ezahlukene ukuze abone ukuthi yikuphi ukunyakaza ongakukwenza nokuthi yini enzima.
• Ukuhlolwa kwegazi: Ngezinye izikhathi ukuhlolwa kwegazi kungenziwa ukuze kutholakale imbangela yezimpawu, isibonelo, ukuhlola isimo esifana nesifo sikashukela.
• Ukuhlolwa kwezithombe: Ukuhlolwa kwezithombe okuvamile okusetshenziselwa ukubheka i-abducens nerve yi- Magnetic Resonance Imaging (MRI) . I-MRI ivumela udokotela wakho ukuthi abone ngokucacile imizwa nezicubu ezingaphakathi kwekhanda lakho.

Yiziphi izindlela zokwelapha izifo ze-Abducens Nerve?

Uma udokotela wakho esethole ukuthi unezinkinga futhi wathola imbangela yezimpawu zakho, uzokwelapha i-abducens nerve eyonakele. Ukwelashwa kungafaka:

• Ukwelapha noma ukuphatha isimo esiyisisekelo esibangela izimpawu. Isibonelo, uma inkinga ibangelwa isifo sikashukela, ukulawula isifo sikashukela kuyisihluthulelo.
• Ukugqoka i-eye patch noma amalensi okulungisa kungasiza ekunciphiseni ukubona okubili.
• Imijovo ye-Botulinum Toxin. Lokhu kuyasetshenziswa ngezinye izikhathi.
• Ukuhlinzwa. Ukuhlinzwa kungadingeka uma ezinye izindlela zokwelapha zingaphumeleli noma kwezinye izimo ezikhethekile.

Khumbula, ukwelashwa okutholayo kungahluka kuye ngomuntu kuye ngembangela yezimpawu zakho, ngakho-ke kubalulekile ukulandela imiyalelo kadokotela wakho ngqo.

Ngingayinakekela kanjani i-Abducens Nevers yami?

Eqinisweni, ukunakekela izinzwa zakho kuwukunakekela umzimba wakho wonke. Izinzwa ziyingxenye yenethiwekhi enkulu yokuxhumana phakathi kobuchopho bethu nemisipha. Ngakho-ke, qiniseka ukuthi udla ukudla okunempilo, uvivinya umzimba njalo, futhi uthola ukwelashwa kwanoma yiziphi izimo ezingaphansi.Ngesikhathi unakekela impilo yakho iyonke, unakekela nemizwa yakho.

Ukuzivikela ekulimaleni ekhanda nakho kubalulekile ukuvikela le nzwa. Njengoba sishilo, le nzwa inde kancane, ngakho-ke isengozini yokulimala.

Uma ufuna ukwazi okwengeziwe ngempilo yakho iyonke noma impilo yezinzwa, ungesabi ukubuza udokotela wakho.

Okokugcina, izinto okufanele uzikhumbule

Ngisho njengoba ufunda lo musho, i-abducens nerve yakho iyasebenza ngaphandle kokuthi wena uqaphele. Singase singaqapheli ukuthi ibaluleke kangakanani empilweni yethu yansuku zonke. Kodwa lo mngane omncane osisiza sibheke kwesobunxele nakwesokudla uyi-nerve enkulu esukela kolunye uhlangothi lobuchopho iye kolunye. Yingakho isengozini enkulu yokulimala.

Ungavikela imizwa yakho ngokunakekela umzimba wakho nangokuqaphela ukugwema izingozi. Uma uneminye imibuzo mayelana nale mizwa, khuluma nodokotela. Ukunakekela umzimba wakho kuyinto engcono kakhulu okufanele uyenze kuqala!
