Na wetin de alaw yu fɔ yɛri ɛn kip yu balans: Di Vestibulocochlear Nerve in simpul wɔd!

Tide wi go tɔk bɔt wan pat na wi bɔdi we rili wɔndaful ɛn we rili impɔtant. Yu dɔn ɛva wɔnda aw yu de yɛri sawnd, ɔ aw yu de balans ɛn kɔntinyu fɔ tinap tranga wan ɛn nɔ fɔdɔm? Sɔmbɔdi de we de ɛp wit ɔl dis, di wan we de kɛr mɛsej frɔm insay wi yes to di bren. Dɛn kɔl dis di vestibulocochlear nerve . Pan ɔl we i go tan lɛk se di nem lɔng smɔl, di wok we i de du rili big. Lɛ wi lan mɔ bɔt am insay wan simpul we.

Wetin na dis vestibulocochlear nerve?

Fɔ tɔk am simpul wan, yu vestibulocochlear nerve na wan strɔkchɔ we gɛt tu pat. Di men wok we i de du na fɔ kɛr di tin dɛn we yu de fil frɔm yu insay yes to yu bren. Nɛv dɛn tan lɛk di smɔl smɔl kebul dɛn we de na wi os. Dɛn kebul ya kin kɛr infɔmeshɔn, lɛk ilɛktrik mɛsej, frɔm ɛni wan pan wi bɔdi in sɛns to di bren. Dɔn di bren kin yuz da infɔmeshɔn de fɔ mek wi bɔdi wok fayn fayn wan.

yu vestibulocochlear nerve de mεntal kכri infכmeshכn frכm tu כgan dεm na yu insay yes. wan na di כgan we de εp yu fכ yεri sawnd , εn di כda wan na di כgan we de εp yu fכ mεnten yu bכ di in ``sεns fכ bεlε.''

di vestibulocochlear nerve na wan pan di twɛlv kraynia nεv dεm na wi ed. Dɛn kraynia nɛv ya de ɛp wi fɔ smɛl, test, tɔch, ɛn mek wi fes. di vestibulocochlear nerve na di et pan dεn tεlv kraynia nεv dεm (cranial nerve VIII כ CN VIII) . I kin min mɔ fɔ yɛri ɛn balans. sכmtεm dεn kin kכl am di כditory vestibular nerve.

So wetin na di men wok we dis nerve de du?

di nem "vestibulocochlear" insεf de gi klyu fכ di tu pat dεm na dis nεv εn dεn wok dεm. I rili simpul, jɔs luk:

• vestibular nerve: Dis na di "vestibulo" pat pan di nem. i de kכri infכmeshכn frכm di כgan dεm na yu vεstibul sistεm to yu bren. dis vestibular כgan dεm na dεn de dεtekt infכmeshכn bכt di posishכn fכ yu ed εn di muvmεnt dεm we yu ed de muv. Yu bren de yuz dis infɔmeshɔn fɔ ɛp yu fɔ kɔntinyu fɔ balans. Tink bɔt am, dis sistɛm de ɛp yu fɔ mek yu nɔ fɔdɔm we yu de waka, rɔn, ɔ shek yu ed.

• di koklia nεv: Dis na di "koklia" pat pan di nem. I kin kɛr sawnd infɔmeshɔn frɔm yu kɔklia , we na wan pat we tan lɛk snɛl na yu insay yes, to yu bren. Yu bren de yuz dis infɔmeshɔn fɔ ɛp yu fɔ no ɛn yɛri sawnd.

dis tu nεv dεm de kam togεda fכ mek di singl nεv we dεn kכl `CN VIII`. Bɔt ivin afta dɛn dɔn jɔyn, ɛni wan de du in yon difrɛn wok – dat na fɔ kɛr mɛsej dɛn we gɛt fɔ du wit balans ɛn kɛr mɛsej dɛn we gɛt fɔ du wit fɔ yɛri.

yu kin ehksplehn likl boht aw di vestibular nerve de wok?

yu vεstibul nεv de kכri infכmeshכn frכm di כgan dεm na di vεstibul sistεm to yu bren stεm . yu vεstibular כgan dεm na tu otolith כgan dεm (dεn kכl dεm bak utricles εn saccules) εn tri sεmisεkyul kanal dεm. כl dεn fayv כgan dεm ya fulכp wit wata εn dεn gεt sεl dεm we de fil. We yu muv yu ed, dis wata ɛn di sɛl dɛn de muv.

dis na aw di vεstibular nεv de wok:

1. di signal bigin: we yu muv yu ed, di wata we de insay di vestibular כgan dεm de muv. Dɔn di sɛns sɛl dɛn we de insay dɛn kin muf. Dis muvmεnt de mek signal bכt yu bכdi in posishכn εn muvmεnt.

2. di nεv sεl dεm (nyuron dεm) de kכri di signal: dεn nεv sεl dεm ya de kכri di signal along di vεstibul nεv. dis mεsej de travul go na wan ples we dεn kכl di vεstibular nyuklios kכmpleks na di bren stεm. Dis kɔmpleks gɛt 4 nyukliɔs dɛn. εvri wan pan dεn nyuklios dεm ya na di bren de sεnd signal to difrεn pat dεm na di bכdi, so dat yu go bεlε.

. כda nyuklios dεm de sεnd sens signal to yu nεk εn leg dεm, we de εp yu fכ kכrekt aw yu de tinap. Sɔm nyukliɔs dɛn kin sɛn sɛns to di mɔsul dɛn na yu yay, we kin ɛp yu yay fɔ kɔntinyu fɔ pe atɛnshɔn pan wan say ivin we yu bɔdi de muv. dεn kכl dis di vεstibulo-okul rεflεks (VOR) . Imajin, we yu de rayd bɔs, na bikɔs ɔf dis VOR yu kin luk sayn na do.

Naw lɛ wi si aw di kɔklia nerve (hearing nerve) de wok.

yu koklia nerve (dεn kכl am bak di כditory nerve) de kכri infכmeshכn frכm yu koklia to yu bren stεm. lεk di כgan dεm na di vεstibular sistεm, yu kכklia fulכp wit wata εn i gεt sεns hεr sεl dεm. We sawnd wev dɛn kam, dɛn wata ɛn sɛl dɛn ya kin shek.

Na dis na aw di kɔklia nerve de wok:

1. di signal bigin: we di sawnd wev dεm rich yu koklia, di basilar mεmbran we de insay amWan mɛmbran we dɛn kɔl di ia drɔm de shek shek. dis vaybrεshכn de mek di sεnsitiv εya sεl dεm na di mεmbran de muv. As di sel dεm de muv, wan signal de jεnarεt bכt di kayn sawnd. Dis inklud tin dεm lεk di frikכnshכn fכ di sawnd wev dεm (i.e., aw di sawnd ay כ lכw - `pitch`) εn di lawd we di sawnd de mek.

2. di signal na di nεv sεl dεm de kכri am: `nyuron` (nεv sεl dεm) de kכri dis signal along di כditory nεv, te i rich wan ples we dεn kכl `koklia nyuklios` insay di bren stεm. tri pat dεm de pan dεn kכklia nyuklios dεm. Ɛni pat kin gɛt difrɛn kayn tin dɛn bɔt sawnd. Fɔ ɛgzampul, sɔm pat dɛn kin gɛt infɔmeshɔn bɔt sawnd dɛn we gɛt smɔl frikshɔn, lɛk bas sawnd dɛn. Ɔda pat dɛn kin gɛt infɔmeshɔn bɔt sawnd dɛn we gɛt ay frikshɔn, lɛk sawnd dɛn we gɛt ay pitch.

3. di bren de proכses sawnd infכmeshכn: di kכklia nyuklios de sεnd sεns signal dεm bכt sawnd to di כditory kכtεks na yu bren. dis de na di tεmporal lכb na di bren. Dis na di say we dɛn de prosɛs ɛn ɔndastand di sawnd infɔmeshɔn we yu de yɛri.

Yu nɔ tink se i wɔndaful? Aw bɔku tin kin apin wit dis smɔl nerv! I tan lɛk wan supa teknɔlɔji insay wi bɔdi.

So usai dis vestibulocochlear nerve de?

di vestibulocochlear nerve de na wan bon pasej we dεn kכl di Internal Auditory Canal (IAC) , we na di say we yu insay yes de kכnekt to di כndasayd fכ yu skel.

• di vεstibul nεv de bigin insay wan bכndεl nεv dεm we dεn kכl di vεstibular ganglion (`Vestibular (Scarpa's) ganglion`) nia di vεstibular כgan dεm. i de jכyn di kכklia nεv insay di `IAC` fכ fכm `CN VIII`. כltu, i de separet frכm di kכklia nεv bak we i rich di vεstibular nyuklios kכmpleks na di bren stεm.
• di koklia nεv de bigin insay wan bכndεl nεv dεm we dεn kכl di spiral ganglion nia di kכklia. dis de jכyn di vεstibular nεv insay di IAC fכ fכm CN VIII. afta dat i de separet frכm di vεstibul nεv we i rich in kכrεspכndεnt nyuklios dεm na di bren stεm.

Fɔ tɔk am simpul wan, i tan lɛk se dɛn tu nɛv ya kin bigin na di insay yes, travul togɛda fɔ shɔt tɛm, dɔn dɛn kin separet bak fɔ du dɛn yon wok we dɛn go insay di bren.

Wetin dɛn mek di vestibulocochlear nerve wit?

di vεstibulokoklia nεv de mek כl di sεns nyuron dεm (afferent nyuron dεm) . dis min se di wangren tin we i de du na fכ kכri signal dεm we de εp di bren fכ prכsεs infכmeshכn bays pan yu sεns dεm (lεk fכ yεri εn di bכdi posishכn). i nכ de kכri mכtal mεsej, dat na mεsej frכm di bren to di mכsul dεm.

Wetin na di kɔmɔn tin dɛm we kin afɛkt di vestibulocochlear nerve?

Bɔt i sɔri fɔ no se sɔm tin dɛn de we kin ambɔg dis impɔtant nerve. Sɔm pan dɛn na:

• Injury: Injury to di pat dɛm na yu skel, mɔ usay yu insay yes de. Tink bɔt am lɛk se yu de nak yu ed.
