Cia peb kawm txog Abducens Nerve - qhov uas pab koj txav koj lub qhov muag mus rau sab no thiab sab ntawd?

Koj puas tau xav paub tias koj ob lub qhov muag txav mus los ntawm sab xis mus rau sab laug zoo nkauj li cas? Thaum peb nyeem ib phau ntawv, thaum peb taug kev ntawm txoj kev, thaum peb saib mus rau qhov ntawd thaum ib tug neeg tab tom tham lus, peb lub qhov muag ua haujlwm zoo kawg nkaus. Yog li, muaj ib tug phooj ywg tseem ceeb heev hauv peb lub taub hau uas pab peb nrog qhov no. Nws yog Abducens Nerve . Peb puas yuav tham txog tus phooj ywg no hnub no?

Abducens Nerve yog dab tsi? Yog hais kom meej...

Hais yooj yim xwb, cov hlab ntsha abducens yog ib tug tswv cuab tshwj xeeb heev ntawm cov hlab ntsha hauv peb lub taub hau. Yog hais kom meej, nws yog qhov thib rau ntawm peb kaum ob lub hlab ntsha cranial (Cranial Nerve VI - CN VI) . Nws txoj haujlwm tseem ceeb yog tswj peb lub qhov muag txav, uas yog, tig nws mus rau sab. Xav txog, qhov no yog cov hlab ntsha uas pab koj tig koj lub qhov muag sab xis mus rau sab xis thiab koj lub qhov muag sab laug mus rau sab laug.

Muaj ib cov leeg tshwj xeeb hauv lub qhov muag los pab nws ua txoj haujlwm no, uas peb hu ua Lateral Rectus Muscle . Yog li ntawd, Abducens Nerve no zoo li tus thawj coj ntawm cov leeg no.

Cov hlab ntsha yog cov uas xa cov lus ntawm peb lub hlwb thiab cov leeg, puas yog? Yog li Abducens Nerve no kuj zoo ib yam.

Nws tsis ua qhov no ib leeg xwb. Ob lub hlab ntsha ntxiv pab peb lub qhov muag txav mus los ua ke. Lawv yog lub hlab ntsha cranial thib peb (Oculomotor Nerve - CN III) thiab lub hlab ntsha cranial thib plaub (Trochlear Nerve - CN IV) . Ua ke, peb lub no tswj peb lub qhov muag txav mus los zoo heev.

Cov hlab ntsha muaj ob lub luag haujlwm tseem ceeb. Ib qho yog los hnov ​​​​​​cov kev xav, uas hu ua Sensory Function . Qhov thib ob yog txav cov leeg nqaij, uas hu ua Motor Function . Peb lub Abducens Nerve tsis muaj kev ua haujlwm sensory. Nws tsuas yog ua haujlwm motor xwb . Ntawd yog, nws txoj haujlwm tsuas yog tig lub qhov muag mus rau sab nraud.

Yog li, qhov tseeb yog dab tsi yog qhov ua haujlwm ntawm Abducens Nerve?

Raws li peb tau hais ua ntej lawm, cov hlab ntsha abducens yog qhov uas tig peb lub qhov muag mus rau sab nraud, uas yog, mus rau sab, thiab cov leeg nqaij lateral rectus yog qhov uas txav koj lub qhov muag sab xis mus rau sab xis thiab koj lub qhov muag sab laug mus rau sab laug. Cov hlab ntsha no kuj ua haujlwm nrog lwm cov leeg nqaij kom tig ob lub qhov muag mus rau sab xis lossis sab laug tib lub sijhawm.

Xav txog seb, koj tab tom nyeem kab lus no tam sim no. Koj ob lub qhov muag maj mam txav mus los ntawm sab laug mus rau sab xis. Lub sijhawm ntawd, koj siv Abducens Nerve thiab Lateral Rectus Muscle no.

Cia peb muab piv txwv ntxiv. Xav txog koj nyob hauv ib lub tiaj ua si zoo nkauj. Tam sim ntawd, koj hnov ​​​​​​ib tug noog hu nkauj hauv ib tsob ntoo rau koj sab xis. Thaum koj tig mus saib ntawd, koj lub paj hlwb abducens qhia rau cov leeg nqaij hauv koj lub qhov muag, "Okay, saib mus rau sab xis." Ces koj tuaj yeem pom tus noog zoo nkauj ntawd. Koj puas nkag siab qhov tseem ceeb ntawm qhov ntawd?

Abducens Nerve nyob qhov twg hauv peb lub cev?

Qhov no yog ib txoj hlab ntsha me me heev, nyob hauv peb lub taub hau, tom qab peb ob lub qhov muag. Nws zoo li ib ceg ntoo.

Peb muaj ob lub paj hlwb Abducens zoo li no, ib qho rau sab laug qhov muag thiab ib qho rau sab xis qhov muag. Cov paj hlwb no khiav ntawm peb lub hlwb (qhov ntawm lub hlwb tom qab ntawm lub hlwb uas txuas rau cov hlab ntsha caj qaum) mus txog rau Lateral Rectus Muscle hauv lub qhov muag. Hauv txoj kev no, lawv yuav tsum dhau los ntawm qhov chaw subarachnoid , lub dura mater , thiab qhov qhib me me hauv lub pob txha taub hau kom nkag mus rau hauv lub qhov muag.

Koj puas paub? Ntawm cov hlab ntsha hauv peb lub hlwb, Abducens Nerve muaj txoj kev ntev thib ob tom qab Vagus Nerve.

Yog li, Abducens Nucleus yog dab tsi?

Qhov no yog ib zaj dab neeg tob me ntsis, tab sis kom yooj yim to taub, Abducens Nucleus zoo li "qhov chaw hais kom ua" ntawm cov hlab ntsha no. Nws zoo li CPU ntawm lub khoos phis tawj. Nws yog lub nucleus no uas qhia rau cov hlab ntsha yuav tsum ua li cas. Txawm hais tias cov hlab ntsha no txuas ntxiv los ntawm lub hlwb mus rau lub qhov muag, lub nucleus no nyob hauv ib feem ntawm lub hlwb hu ua Pons . Pons nyob rau sab saum toj, tom qab ntawm peb lub hlwb. Qhov ntawd txhais tau tias nws nyob hauv qab Midbrain thiab saum toj ntawm Medulla Oblongata (qhov no yog qhov ua ntej nws txuas rau lub hlwb qaum).

Puas muaj ib yam mob uas feem ntau cuam tshuam rau Abducens Nerve?

Yog, hmoov tsis zoo, muaj teeb meem uas tuaj yeem cuam tshuam rau cov hlab ntsha no. Qhov feem ntau ntawm cov no yog Abducens Nerve Palsy , lossis Sixth Nerve Palsy . Qhov no yog thaum cov hlab ntsha raug puas tsuaj, ua rau Lateral Rectus Muscle tsis muaj zog thiab qee zaum tuag tes tuag taw .

Muaj ntau yam ua rau qhov no:

• Kab mob ntshav qab zib
• Ntshav siab
• Kev raug mob taub hau
• Mob stroke
• Ntau lwm yam laj thawj

Qhov tseem ceeb tshaj plaws yog mus ntsib kws kho mob tam sim ntawd yog tias koj muaj ib qho ntawm cov tsos mob no kom nrhiav tau qhov ua rau .

Kuj tseem hais tias cov hlab ntsha no yooj yim raug mob vim nws mus deb ntawm ib kawg ntawm lub hlwb mus rau lwm qhov. Vim nws ntev, nws yooj yim raug mob.

Cov tsos mob ntawm qhov teeb meem nrog Abducens Nerve yog dab tsi?

Xav txog tias koj cov hlab ntsha abducens raug puas lawm. Ces cov leeg nqaij uas tig lub qhov muag mus rau sab nraud tsis tau txais cov lus los ntawm lub hlwb kom raug. Yog li ntawd, koj yuav muaj cov tsos mob zoo li:

• Nyuaj lossis tsis muaj peev xwm tig lub qhov muag sab laug thiab/lossis sab xis.
• Pom ob sab (Diplopia) - Qhov no yog thaum koj pom ob yam tib lub sijhawm. Qhov no yuav pom tseeb dua thaum saib ntawm lub qhov muag uas raug mob.
• Qhov muag tsis sib luag - Thaum ib lub qhov muag ntsia ncaj nraim rau pem hauv ntej, lwm lub qhov muag yuav zoo li raug rub mus rau hauv.
• Qhov muag nkees los yog mob.

Yog koj xav li no thiab, tsis txhob tsis quav ntsej nws, puas yog?

Yuav ua li cas los xyuas seb koj lub paj hlwb Abducens puas noj qab haus huv?

Tus kws kho mob lossis kws kho qhov muag yuav kuaj xyuas qhov kev noj qab haus huv ntawm cov hlab ntsha no. Lawv yuav siv cov kev kuaj xws li:

• Kev kuaj qhov muag: Tus kws kho mob yuav kuaj koj qhov muag pom kev thiab hais kom koj txav koj ob lub qhov muag mus rau ntau qhov kev taw qhia kom pom tias koj tuaj yeem ua dab tsi thiab dab tsi nyuaj.
• Kev kuaj ntshav: Qee zaum kev kuaj ntshav yuav ua tau los nrhiav qhov ua rau muaj cov tsos mob, piv txwv li, los kuaj xyuas seb puas muaj mob xws li ntshav qab zib.
• Kev kuaj duab: Ib qho kev kuaj duab uas siv ntau los saib cov hlab ntsha abducens yog Magnetic Resonance Imaging (MRI) . MRI tso cai rau koj tus kws kho mob pom cov hlab ntsha thiab cov nqaij hauv koj lub taub hau kom meej.

Cov kev kho mob rau cov kab mob Abducens Nerve yog dab tsi?

Thaum koj tus kws kho mob kuaj pom thiab pom qhov ua rau koj cov tsos mob, lawv yuav kho cov hlab ntsha abducens uas puas lawm. Kev kho mob yuav suav nrog:

• Kev kho lossis tswj tus mob uas ua rau muaj cov tsos mob. Piv txwv li, yog tias qhov teeb meem yog los ntawm tus kab mob ntshav qab zib, kev tswj tus kab mob ntshav qab zib yog qhov tseem ceeb.
• Hnav daim ntaub thaiv qhov muag lossis cov iav kho qhov muag tuaj yeem pab txo qhov pom kev ob npaug.
• Kev txhaj tshuaj Botulinum Toxin. Qhov no qee zaum siv.
• Phais Mob. Tej zaum yuav tsum tau phais mob yog tias lwm yam kev kho mob tsis ua tiav lossis qee kis tshwj xeeb.

Nco ntsoov, kev kho mob uas koj tau txais yuav txawv ntawm ib tus neeg mus rau ib tus neeg nyob ntawm seb ua rau koj cov tsos mob ua rau koj muaj mob li cas, yog li nws tseem ceeb heev uas yuav tsum ua raws li koj tus kws kho mob cov lus qhia kom meej.

Kuv yuav saib xyuas kuv cov Abducens Nerves li cas?

Qhov tseeb, kev saib xyuas koj cov hlab ntsha yog kev saib xyuas tag nrho koj lub cev. Cov hlab ntsha yog ib feem ntawm kev sib txuas lus loj heev ntawm peb lub hlwb thiab cov leeg.
