Aw di nerv dεm de wok wit כda pat dεm na wi nervous sistεm?

Okay, naw mek wi si, dis ‘nerves’ no de wok onli. Dɛn kin du ɔl dis togɛda wit di ɔda pat dɛn na wi nervɔs sistɛm. Aw dat kin apin?

A dɔn tɔk bifo tɛm se tu men pat dɛn de na wi nervɔs sistɛm:

1. 1. 1. .Pεrifεral Nεv Sεstem (PNS): Dis na di nεtwכk fכ di nεv dεm we de rכn כlsay na di bכdi. I tan lɛk di rod dɛn we de pas na di kɔntri. dis rod dεm (nεv dεm) de kכlekt mεsej (sεns) dεm frכm difrεn pat dεm na di bכdi εn de bכn dεm to di men rod, di spεnal kכd.

2. ‘Sεntri Nεv Sistem’ (Sεntral Nεv Sistem - CNS): Dis na wi kכntrol sεnta. Dat min se, di bren ɛn di spɛshal kɔd . na dis ‘sεntri nεv sεstem’ we de gεt כl di mεsej dεm we de kכmכt frכm di ‘pεrifεral nεv sεstem’, כndastand dεm, εn disayd ‘wetin fכ du nεks?’. afta dat dεn disizhכn dεm de go bak to di rilevεnt ples dεm tru di ‘nεv dεm’.

Tink bɔt am dis we. Yu gɛt chukchuk we stɔp na yu leg. di pen mεsej de sεnd di nεv dεm na yu lεg (pat pan di PNS) to yu spεnal kכd (pat pan di CNS). frכm di spεnal kכd, di mεsej de go to yu bren (di כda pat pan di CNS). Di bren ɔndastand, "O, wan chukchuk stɔp insay mi, i de at." afta dat di bren de sεnd mεsej bak tru di nεv dεm to yu leg mכsul dεm, we de tεl dεm fכ "tek yu leg kכmכt." En yu tek yu leg go. Ɔl dis kin apin insay wan blink!

Sɔmtɛm dɛn ansa ya kin apin as riflɛsɛf akshɔn , dat na, bifo wi ivin tink bɔt am, na wan lɔwa lɛvɛl na di kɔnshɛns. Wan ɛgzampul na di akt we wi bin dɔn tɔk bɔt fɔ pul in an pan sɔntin we wam. Dis kin apin bifo di mɛsej rich na di bren, usay di spɛshal kɔd kin disayd ɛn du am. Dis kin mek wi ebul fɔ rɔnawe pan bad tin kwik kwik wan.

Wetin kin apin insay wan nerve we dɛn sɛn mɛsej?

Dis chenj we dɛn kin chenj mɛsej nɔ kin jɔs apin. Na wan rili kɔmpleks, yet wɔndaful prɔses. Lɛ wi luk wetin kin apin we ilɛktrik impuls de travul along wan nɛv:

1. fכs, dis ilektrikal signal de travul along wan lכng pat pan di nεv we lεk waya we dεn k כl ‘akson’ . Tink bɔt am lɛk kɔrɛnt we de flɔ tru waya.

2. we i rich di εnd pan di nεv, we dεn k כl 'akson hilכk' , dis ilektrikal signal de bi kεmikכl signal .

3. Dɔn, dis kεmikכl signal de mek spεshal kεmikכl mεsenja dεm we dεn kכl nyurotransmitta . dis dεm de kכmכt frכm wan nyuron (nεv sεl) insay wan sכmכl gap bitwin di nεks nyuron כ wan mכsul. Wi kin kɔl dis gap sinaps . I tan lɛk brij.

4. dεn ‘nyurotransmitta’ patikyula dεm we dεn rilis de go to εn atak spεshal ‘rεsεptor’ dεm na di nεks ‘nyuron’ כ mכsul. Jɔs lɛk aw ki kin fit insay lɔk.

5. Wit dis konekshon, dat kemikal signal de bi ilektrikal signal bak.

6. Dɔn dis nyu ilɛktrik signal de travul along da sɛkɔn ‘nyurɔn’ de.

7. dis we ya, dis prכsεs de kכntinyu te di mεsej rich in tכgεt – dat na, wan say lεk di bren, wan mכsul, כ wan gland.

Imajin aw ɔl dis kin apin kwik kwik wan! Bɔku bɔku pan dɛn kayn mɛsej dɛn de kin chenj insay wi bɔdi insay smɔl sɛkɔn.

Usay dɛn nerv ya de na wi bɔdi?

Infakt, di nerv dɛn de ɔlsay na wi bɔdi! Jɔs lɛk aw blɔd vesel dɛn de ɔlsay. כl di nεv dεm de stat na wi spεnal kכd. Sɔm kin bigin dairekt na di bren. Dɔn dɛn kin branch ɔlsay na di bɔdi.

Na sɔm pan di men eria dɛm fɔ ‘nɛv dɛm’:

• Insay di an dɛn: Di nerv dɛn de rɔn frɔm yu sholda to yu finga dɛn. εgzampl dεm na di Ulnar nεv , di Median nεv , εn di Radial nεv . Sɔntɛnde, we dɛn hit yu na yu ɛlb, i kin tan lɛk se ilɛktrik shɔk de go tru yu an bikɔs di Ulnar nɛv dɔn kɔmprɛs.
• Chɛst ɛn bɛlɛ: Dis eria gɛt impɔtant nerv dɛn lɛk di phrenic nerve , we de ɛp fɔ blo, ɛn di vagus nerve, we de involv fɔ mek bɔku pan wi insay pat dɛn wok.
• Fes: Nεv dεm lεk di fes nerve, we de εp yu smayl, tכk, εn klos yu yay, di trigeminal nerve , we de bכn sens na di fes , εn di optik nerve , we de kכri wetin yu si to di bren, de na di fes.
• Insay di leg dɛm: Bɔku nerv dɛm de we de kɔntrol di sɛns ɛn muvmɛnt na di leg dɛm. Fɔ dɛn tin ya, yu go dɔn yɛri bɔt di sciatic nerve . Dis na di nerve we lɔng pas ɔl ɛn big pas ɔl na di bɔdi. We dɛn kɔmprɛs dis nɛv, i kin mek pɔsin gɛt sciatica. כda nεv dεm de bak na di leg dεm lεk di fεmoral nεv εn di tibial nεv .
• di pεlvis: Dis εria gεt nεv dεm we riliyt to di wok εn sεns fכ di כgan dεm, fכ egzampl , di pudendal nεv .

fכ simpul wan, dis nεtwכk fכ ‘nεv dεm’ de kכmכt frכm di tכp dεm fכ yu finga dεm te to di tכp pat pan yu ed.

Aw di strɔkchɔ fɔ wan nerve kin fɔm?

Okay, mek wi luk naw wetin de insay wan ‘nerve’ en aw dem mek am. ‘Nɛv’ tan lɛk big kebul we gɛt bɔku smɔl smɔl waya dɛn insay.

Bɔku men pat dɛn de fɔ wan nerv:

• aksכn dεm: Dis na di bכndεl dεm we lεk waya we de na di midul pan di nεv. Na dɛn na di men we fɔ kɛr mɛsej.
• Dendrites: Dis na di branch pat dεm na nyuron we de gεt ilektrikal mεsej frכm כda nyuron dεm.
• endoneurium: dis na di kכnektiv tisu layεr we de rawnd di aksכn.
• Pɛrinɛriɔm: .di layεr fכ kכnektiv tisu we de rawnd sכm bכndεl dεm (fascicles) we dεn fכm bay di jכyn fכ sεvεra aksכn dεm.
• Epineurium: Dis na di layt we de na do pas ɔl na di kɔnektiv tisu we de kɔba di wan ol nerve, lɛk di plastic sheath we de na do na di kebul.

Wan ɔda tin de we rili impɔtant, we dɛn kɔl di ‘Myelin Sheath’ . wan kayn sεl de we dεn kכl ‘Oligodendrocytes’ we de rawnd di ‘akson dεm’ fכ di ‘nεv dεm’ insay yu bren, εn wan kayn sεl de we dεn kכl ‘Schwann sεl dεm’ rawnd di ‘akson dεm’ fכ di ‘nεv dεm’ we de na do na di bren εn spεnal kכd (CNS).

כl tu di oligodεndrכsayt dεm εn di Schwann sεl dεm gεt wan fεt sכbstans we dεn kכl maylin. dis maylin de fכm wan mכlti layεr sεt rawnd di aksכn, we dεn kכl di maylin sεt. Dis tan lɛk di insuleshɔn we de rawnd ilɛktrik waya. dis maylin sεt na in de alaw ilektrikal mεsej dεm fכ travul kwik kwik wan along wan nεv. Imajin, if dis maylin swɛt dɔn pwɛl, jɔs lɛk aw di insuleshɔn we de na waya de lik, di nɛv dɛn nɔ go ebul fɔ sɛn mɛsej kwik kwik wan. Sɔntɛnde, mɛsej kin stɔp fɔ sɛn am kpatakpata.

Ɛni sik de we kin afɛkt di nerv dɛn?

Yɛs, i sɔri fɔ no se, difrɛn sik ɛn dizayd dɛn kin afɛkt wi rili impɔtant nerv dɛn bak. we di nerv dεm dεn dכn pwεl, כ we di transmishכn fכ mεsej tru dεm de disrupt, difrεn nyurolכjik kכndyushכn dεm kin apin.

Na sɔm kɔmɔn tin dɛm wae kin afɛkt di nerv dɛm:

• Pɛriferal Nyuropati: Dis kin min fɔ pwɛl di nɛv dɛm we de na do na yu bren ɛn yu spɛnal kɔd. Dis kin gɛt bɔku tin dɛn we kin mek i apin. Dis sik kin kam pan pipul dɛm wae gɛt shuga . Di sayn dɛm na fɔ swɛt, fɔ swɛt, fɔ fil pen, ɛn fɔ wik na yu an ɛn fut dɛm.
• Sciatica: A don tok abaut dis likl bit bifo. dis na we prεshכn כ kכmpreshכn de pan di nεv rכt dεm na yu lכw bכk, כ pan di sciatic nεv we de rכn dכn yu leg dεm. Dis kin mek yu fil bad bad wan ɛn yu nɔ kin fil fayn we kin kɔmɔt na yu bak fɔ go dɔŋ yu leg dɛn.

Bɔrku ɔda tin dɛn de lɛk dis wae kin afɛkt di nerv dɛm, so if yu gɛt nɔrmal tin wae yu de fil, yu de fil pen, yu wik, ɔr yu de chenj aw yu de fil, i impɔtant fɔ go to dɔktɔ.

Wetin wi go du fɔ mek wi nerv dɛn kɔntinyu fɔ gɛt wɛlbɔdi?

Wi nerv dɛn tan lɛk sɔntin we gɛt valyu. So na wi wok fɔ mek dɛn gɛt wɛlbɔdi ɛn wɛl. Fɔ du dat, sɔm simpul, bɔt rili impɔtant abit dɛn de we wi kin fala:

• Nɔ smok, ɔ if yu de smok, lɛf fɔ smok: Smok nɔ jɔs de ambɔg di nerv dɛn, bɔt i de ambɔg di wan ol bɔdi.
• It it we gɛt fayn fayn tin dɛn fɔ it: I rili impɔtant fɔ it it we gɛt bɔku bɔku tin dɛn we gɛt ɔl di tin dɛn we dɛn dɔn plant, fayn fayn fat, tin we nɔ gɛt bɛtɛ prɔtin, frut, ɛn vɛjitebul. dis dεm de gi di nyutrishכn we nid fכ di nerv dεm.
• Limit alcohol drink: If yu drink pasmak, dat kin pwɛl yu nerves.
• Kɔntrol di mɛdikal kɔndishɔn dɛm wae kin afɛkt di nerv dɛm: Fɔ ɛgzampul, if yu gɛt sik lɛk Dayabitis Mɛlitus , fɔ kɔntrol am fayn fayn wan rili impɔtant fɔ protɛkt yu nerv dɛm.
• Ridyus strɛs: Stret fɔ lɔng tɛm nɔr fayn fɔ di nerv dɛm. Tray fɔ ridyus strɛs tru tin dɛn lɛk fɔ tink gud wan ɛn fɔ du ɛksɛsayz.

• Drink inof wata: Fɔ kip di bɔdi gɛt wata, i kin ɛp bak fɔ mek di nerv dɛn gɛt wɛlbɔdi.

If yu fala dɛn abit ya, i nɔ go ɛp yu fɔ kip yu nerv dɛm nɔmɔ, bɔt yu ɔl nervɔs sistɛm wɛl.

Wetin ɔda tin yu kin aks yu dɔktɔ bɔt nerv?

If yu gɛt ɛni kwɛstyɔn ɔ tin we de mɔna yu bɔt yu nerv, ɔ if yu gɛt sɔm kayn sayn dɛn we nɔ kɔmɔn, yu fɔ rili go to dɔktɔ. We yu du dat, yu kin aks kwɛstyɔn dɛn lɛk dɛn wan ya:
