Yu dɔn ɛva wɔnda aw wi yay kin izi fɔ rol dɔŋ we wi de waka dɔŋ wan stej, luk di it dɛn we de na di tebul, ɔ rid sɔntin na wi fon? Wi kin du dɛn tin ya ɔltɛm, bɔt wi nɔ kin tink bɔt di wɔndaful tin we de biɛn am, nɔto so? Infakt, wan smɔl, bɔt rili impɔtant ‘waya’ we de kɔmɔt na wi bren, we na wan nerv, de ɛp wi fɔ du dis wok. Tide wi go tok boht dis likl hiro, di trochlear nerve.
Wetin na dis Trochlear Nerve?
Fɔ tɔk am simpul wan, di trochlear nerve na wan nerve we de kɛr signal frɔm yu bren to wan patikyula mɔsul na yu yay. Fɔ tɔk strikt wan, na motoka nerve. dis min se i nכ de kכri infכmeshכn fכ di sεns to di bren, bכt i de kכri di mεsej frכm di bren to di rayt ples fכ muv. Jɔs lɛk aw di kɔrɛnt we de kɔmɔt na di switch to layt na wi os kin pas na waya.
12 pe pan dεn men nεv dεm de insay wi ed. Wi kin kɔl dɛn kraynia nɛv ya. di fכs pan dεn nεv dεm ya na di trochlear nerve. Na dat mek dɛn kin kɔl am bak di fɔs kraynia nɛv , ɛn dɔktɔ dɛn kin kɔl am (CN IV) fɔ shɔt tɛm. Wi gɛt tu pan dɛn nerv ya, wan fɔ di rayt yay ɛn di ɔda wan fɔ di lɛft yay. Dɛn ɔl tu gɛt di sem wok.
Wetin rili de apin to dis nerve?
Di trochlear nerve gɛt wan men wok nɔmɔ. Dat na fɔ sɛn signal to di supɛriɔr oblique mɔsul we de ɔp wi yay fɔ muv. Dis nerv ɛn dis mɔsul de wok togɛda fɔ mek wi ebul fɔ:
- Luk dɔŋ: Imajin se yu de luk dɔŋ we yu de waka na strit, yu de go dɔŋ wan stej, ɔ yu de luk dɔŋ na yu plet we yu de it. Dɛn tu tin ya togɛda na dɛn de mek yu yay luk dɔŋ ɔltɛm.
- Tɔn yu yay insay: Dis kin ɛp bak fɔ tɔn yu yay insay.
- Tכn di yay dεm na do: Dis kin kכntribyut bak fכ tכn di yay dεm kכmכt frכm di nos εn kכmכt na do.
Di nem ‘trochlear’ kɔmɔt frɔm di Latin wɔd ‘trochleae’, we min ‘pulley’. dis na biכs di supεriכr oblique mכsul we de kכntro dis nεv, bifo i kכnekt to di yay, de pas tru wan lכp fכ tisu we de wok lεk pul. Jɔs lɛk aw rop kin pas oba pul we dɛn de pul wata na wɛl. Dis na di rizin we mek dɛn kin kɔntrol di yay muvmɛnt fayn fayn wan.
Ɔda nerv dɛn de we de ɛp fɔ muv di yay. I fayn fɔ mɛmba dɛn wan ya bak:
- Okulomotכr nεv (CN III) .
- Abducens nεv (CN VI) .
- di fes nεv (CN VII) - dis de mεntal εp fכ klos di aylid dεm.
Usay dis nerve de insay wi ed?
Pan ɔl we dis nerve de kɔntrol wan mɔsul nɔmɔ, di joyn frɔm we dɛn fɛn da mɔsul de to dis nerv kin lɔng smɔl. I tan lɛk pɔsin we de travul we de travul fɔ lɔng tɛm. Dis joyn de stat na wi bren stem. Frɔm de, i kin pas na 4 men say dɛn we i kin stɔp te i rich na di yay.
1. Trochlear nucleus: Dis na di say we di nerve de stat. Dat min se, di pɔynt we de nia di bren pas ɔl. I de na di tap pat pan di bren stem.
2. Ambient cistern: dis nεv de pas nia di protεktiv mεmbran dεm (meninges) we de rawnd di bren. Dɛn kɔl dis pat dis.
3. Cavernous sinus: Dis na wan ples we lεk kכva na di midul pan wi sכkul. Di nerve de pas bak tru dis.
4. כbit: fכ finish, di yay de go insay di כbital kεviti, di bכni kכva na di sכkul usay di yay de. Dis na di say we di nεv de kכnekt to di say we i de go, we na di supεriכr oblique mכsul.
Wetin kin apin if di trochlear nerve dɔn pwɛl?
If dis nerve dɔn pwɛl, i kin afɛkt di we aw yu yay de muv ɛn di we aw yu de si. Dɔktɔ dɛn kin kɔl dis sik fɔs nerve palsy ɔ trochlear nerve palsy. Bɔrku kɔmɔn sayn dɛm de fɔ dis sik.

Wetin na di tin dɛn we kin mek dis nerve pwɛl?
di trochlear nerve gεt wan lכng rod tru di sכkul, we de mek i izi fכ injuri pas כda kraynia nerv dεm, spεshal wan fr כm ed trauma .
- Aksidɛnt dɛn we kin apin na motoka (espɛshali motoka aksidɛnt dɛn) .
