Unuka Njani? Ukuqonda i-Olfactory Nerve!

Ngaba wakha wazibuza ukuba uliva njani ivumba leentyatyambo ezintle, ivumba elimnandi lesidlo sakho osithandayo esiphekiweyo ekhaya, okanye ivumba lomhlaba lemvula emhlabeni? Emva kwala mava kukho inxalenye encinci kodwa ebalulekileyo yomzimba wakho: i- Olfactory Nerve . Namhlanje, makhe sihlolisise le mithambo-luvo imangalisayo—iqhawe elingadunyiswanga lemvakalelo yakho yokuvumba.

Yintoni i-Olfactory Nerve?

Ngamafutshane, i-olfactory nerve yakho yi -cranial nerve yakho yokuqala (i-Cranial Nerve I okanye i-CN I) . Yeyona mithambo-luvo iphambili ilishumi elinesibini ephuma ngqo ebuchotsheni bakho. Ikwathathwa njengenxalenye yenkqubo yakho ye-autonomic nerve , elawula imisebenzi emininzi emzimbeni wakho.

Indima yayo ephambili kukukunika ingqiqo yokuvumba. Okumangalisayo kukuba, yeyona mithambo-luvo imfutshane emzimbeni wakho. Iqala ezantsi kwengqondo yakho ize idlulele kwinxalenye ephezulu yempumlo yakho. Kuyamangalisa ngokwenene ukuba isakhiwo esincinci kangaka senza umsebenzi obaluleke kangaka!

Yintoni umsebenzi oyintloko we-Olfactory Nerve (CN I)?

Umsebenzi wayo ophambili kukukunceda uchonge amavumba ahlukeneyo, ukusuka kwiziqholo kunye namavumba okupheka ukuya kwivumba leentyatyambo ezintsha. Kodwa oku kusebenza njani kanye kanye?

Xa udibana nento enevumba elimnandi, ikhupha iimolekyuli ezincinci nezingabonakaliyo emoyeni. Njengoko uphefumla, ezi molekyuli zihamba ngeempumlo zakho. Phezulu kwimpumlo yakho, iiseli ezikhethekileyo ezibizwa ngokuba zii-olfactory receptors zibamba ezi molekyuli. Ezi receptors emva koko zithumela umyalezo nge-olfactory nerve engqondweni yakho, zisithi, “Kukho ivumba elithile.” Le yindlela oqonda ngayo ngoko nangoko ivumba lerozi okanye ivumba elimnandi lesidlo sangokuhlwa esimnandi.

Isebenza njani inkqubo yokuvumba?

Inkqubo yakho yokuvumba ikuvumela ukuba ubone amavumba ngeendlela ezimbini eziphambili:

1. Ngempumlo (i-Orthonasal olfaction): Njengoko bekutshiwo, iimolekyuli ezivela kwizinto ezinevumba zingena emakhaleni akho kwaye zivuselele ii-olfactory receptors. Ezi receptors zisebenza kwiindidi ezahlukeneyo, njengokuba imibala ephambili ixutywa njani ukwenza uluhlu olubanzi lwemibala.

2. Ukusuka ngasemva komphimbo (i-Retronasal olfaction): Xa uhlafuna okanye uginya ukutya, iimolekyuli ezinuka kamnandi ziyakhutshwa. Ezi zihamba ngasemva komphimbo wakho ziye kwii-receptors ze-olfactory empumlweni yakho. Yiyo loo nto uhlala ufumana incasa epheleleyo kunye nevumba lokutya ngelixa usitya.

I-Olfactory Mucosa kunye nendima yayo

I-mucosa yakho yokunuka , ekwindawo ephezulu yempumlo yakho, idlala indima ebalulekileyo. Iqulethe iintlobo ezahlukeneyo zeeseli:

• Iiseli ze-Olfactory receptor: Ezi seli zibamba iimolekyuli zevumba. Zinenkqubo ye-dendritic efikelela kwi-lining yempumlo ukuze zibone ivumba kunye nenkqubo ephakathi ethumela umyalezo engqondweni.
• Iiseli ezigcina umzimba usempilweni: Ezi zibonelela ngenkxaso yesakhiwo kunye ne-metabolism kwizicubu ezijikelezileyo.
• Iiseli zeBasal: Ezi ziiseli ze-stem ezinoxanduva lokuvuselela iiseli ze-olfactory receptor kunye neeseli ze-sustent.

Yintoni i-anatomy ye-Olfactory Nerve?

Ngokungafaniyo nezinye ii-nerve ze-cranial ezivela kwi-brainstem, i-nerve yakho yokuhomba ivela ngqo kwi- cerebrum (inxalenye ephezulu yobuchopho). Omnye umthambo onokwenza oku yi-optic nerve (Cranial Nerve II).

Iifayibha ze-olfactory nerve zihamba umgama omfutshane ukuya kwi- olfactory bulb . Ngaphambi kokuba zifike kwi-bulb, ezi fayibha ze-nerve zidlula kwithambo elincinci, elifana nesiponji elibizwa ngokuba yi- cribriform plate , elahlula umngxuma wempumlo yakho nobuchopho bakho.

Zithini iimpawu ze-Olfactory Nerve engasebenzi kakuhle?

Iingxaki kwinkqubo yokuhogela zinokubangela iimeko ezahlukeneyo:

• I-Anosmia: Ukulahlekelwa ngokupheleleyo kwemvakalelo yokuvumba .
• I-Dysosmia (ekwaziwa ngokuba yiPhantosmia): Ukuba nevumba elibi, elingathandekiyo, okanye elingaqhelekanga ngaphandle kwesizathu esicacileyo, njengevumba lokutsha okanye ukubola.
• I-Hyposmia: Ukungakwazi ukuvumba kakuhle , apho amavumba aqhelekileyo abonakala ebuthathaka okanye engathandekiyo.
• I-Parosmia: Ukuphazamiseka kwevumba , apho amavumba aqhelekileyo abonwa ngendlela engafanelekanga—umzekelo, ukutya okuthandayo kunokunuka ngequbuliso njengeekhemikhali okanye ukungunda.

Zeziphi iimeko ezinokuchaphazela i-Olfactory Nerve?

Iimeko ezininzi zonyango kunye nezinto zangaphandle zinokuchaphazela ukusebenza kwe-olfactory nerve yakho:

• Usulelo lweempumlo kunye nee-polyps zeempumlo .
• Ukusetyenziswa kwecuba (kuquka icuba okanye i-vaping).
• Ucoceko lwamazinyo olungekho semgangathweni .
• Ukuchanabeka kwiityhefu zokusingqongileyo kunye neekhemikhali ezifana nezibulali-zinambuzane .
• Ukulimala kakhulu entloko, kuquka ukuxhuzula .
• Amayeza athile, afana nee-antibiotics ezithile .
• Intsholongwane ethi `SARS-CoV-2` ebangela i-COVID-19 ( uvavanyo lwe-antibody lunokubaluleka kwabanye).
• Umhlaza wentloko nentamo .
• Iswekile yemellitus .
• Isifo sika-Alzheimer .
• Iithumba zobuchopho .
• Isifo sikaParkinson .
• Isifo sokuwa .

Kubalulekile: Njengoko ubona, ukulahleka okanye ukuncipha kwemvakalelo yakho yokuvumba ngamanye amaxesha kunokuba luphawu lwemeko embi kakhulu engaphantsi. Ukuba ufumana olu tshintsho, kubalulekile ukulujonga ngokusondeleyo.

I-COVID-19 iyichaphazela njani indlela esiva ngayo ivumba?

Kubhaliwe kakuhle ukuba abantu abaninzi abosulelwe yi-COVID-19 baphelelwa livumba. Abaphandi bakholelwa ukuba intsholongwane ethi 'SARS-CoV-2' inokonakalisa iiseli ezixhasayo ezijikeleze ii-neurons ze-olfactory receptor. Iindaba ezimnandi zezokuba kubantu abaninzi, imvakalelo yokuvumba iyabuya, nangona kungathatha iinyanga ezininzi. Umonde ubalulekile ngexesha lokuchacha.

Yintoni onokuyenza ukukhusela impilo yakho yokunuka?

Nangona ezinye iimeko ezifana nezifo zemithambo-luvo okanye iithumba zingaphaya kwamandla akho, ungathatha amanyathelo okuzikhusela ukuze ugcine impilo yakho isempilweni:

• Ziphephe izinto ezinobungozi obukhulu ezinokubangela ukwenzakala engqondweni.
• Hlala usesikhathini ngokugonyelwa i-COVID-19 .
• Nxiba imaski yokukhusela xa usebenza ngeekhemikhali okanye kwiindawo ezinemisi evuthayo.
• Yeka ukusebenzisa icuba ukuba utshaya okanye uvape ngoku.
• Gcina ucoceko lomlomo oluhle kakhulu , kuquka ukuxubha ibhrashi kunye nokutshiza i-floss imihla ngemihla.
• Lawula iimeko zempilo ezifihlakeleyo ezifana nesifo seswekile ngolwalathiso olufanelekileyo lwezonyango.
• Sebenzisa izixhobo zokhuseleko ezifana nezigcina-ntloko ngexesha lemidlalo ukuthintela ukuxhuzula.

Ufanele uye nini kugqirha?

Ukuba ubona nayiphi na kwezi zilandelayo, cwangcisa idinga nomboneleli wakho wezempilo:

• Utshintsho oluqhubekayo kwindlela obona ngayo amavumba .
• Ukulahlekelwa ngequbuliso yimvakalelo yakho yokunuka .
• Ukuba nevumba elibi okanye elingaqhelekanga elingaqhelekanga .

Kutheni ingcebiso yezonyango yobungcali ibalulekile?

Ukubonisana nogqirha kubalulekile kuba ivumba lakho libalulekile kukhuseleko lwakho kunye nempilo-ntle yakho. Umzekelo:

• Ukulahlekelwa yivumba kunokubangela utshintsho ekutyeni , nto leyo enokubangela ukuba utye kakhulu okanye kancinci kakhulu.
• Usenokungakwazi ukubona iimeko eziyingozi , njengokuvuza kwegesi, umsi ovela emlilweni, okanye ukutya okonakeleyo.

Iingcinga Zokugqibela

I-olfactory nerve (CN I) ibalulekile kumgangatho wobomi bakho. Nangona iimeko ezahlukeneyo ezifana ne-COVID-19, isifo seswekile, okanye iingxaki zemithambo-luvo zinokuchaphazela le mithambo-luvo, ukuhlala uzimisele ngempilo yakho yeyona ndlela ilungileyo yokuzikhusela.

Ukuba ubona naluphi na uvakalelo okanye utshintsho kwindlela oziva ngayo ivumba, nceda udibane nogqirha wakho. Banokukunceda ufumanise unobangela kwaye baxoxe ngokuba ingaba ivumba lakho liya kuphila na. Umboneleli wakho wezempilo angakunika nesikhokelo sendlela yokuhlala ukhuselekile kwaye ugcine indlela yokuphila esempilweni nokuba ivumba lakho liyachaphazeleka.

Yonke inxalenye yomzimba wakho ixabisekile; ukuyinyamekela luxanduva olufanele lubekwe phambili.
