Iyo vagus nerve ndiyo nheyo refu kwazvo yehutongi hwehutongi hwehutongi uye ndeimwe yemisungo inokosha zvikuru mumuviri. Iyo vagus nerve inobatsira kutonga zvinhu zvakawanda zvinotambudza zvehutano hwevanhu, kusanganisira kushaya kwemwoyo, kushanda kweropa, kuputika, kudya uye kunyange kutaura. Nokuda kwechikonzero ichi, sayenzi yezvokurapa yakave ichida kutsvaga nzira yekugadzirisa basa reve vagus nerve.
Chii Chinonzi Vagus Nerve?
Iyo vagus nerve (inozivikanwawo seyegumi yegunha yemitsipa) ndeyeta yakareba kwazvo iyo inotangira muuropi inowira uye inopfuurira pasi nemutsipa uye muchipfuva uye mumimba. Inopa kusununguka kumwoyo, midzi midzi yeropa, mhepo, mapapu, denda, dumbu, uye matumbo.
Nepo kune imwe mbiri vagus nerve (kuruboshwe uye kurudyi), vanachiremba vanowanzotaurira pamwe chete se "vagus nerve."
Iyo vagus nerve inobatsira kudzora misungo yakawanda yehuro uye yezwi izwi. Inonyanya kuita basa mukuraira kutengesa kwemoyo uye kuchengetedza chirwere chepamuviri mukushanda. Izvo vagus nerve anewo ruzivo rwemashoko kubva kune nhengo dzomukati dzakadzokera kuuropi.
Nei Chirwere cheVagus Chichikosha?
Zvichida zvakakosha zvikuru zvevash nerve ndeyekuti inhengo huru yemuviri inokonzera mishonga, inopa sarasimpatitic fibers kune nhengo dzose dzepamusoro, mutsipa, chifuva, uye mimba.
Iyo vagus nerve inokonzera gag reflex (uye kukanganiswa kwekukanganiswa apo munzeve inonzwa inokurudzirwa), kunonoka kutengesa kwemwoyo, kudzora kutuka, kuronga ropa reropa, kukurudzira kuparara kwegumbo remimba, nekudzora tauriri yemavhesi.
Kukurudzirwa kusinganzwisisiki kwesimba regusimba kunogona kubudisa izvo zvinonzi " vasovagal reflex ," iyo inosanganisira kuerekana ichiderera kuwedzerwa kweropa uye kunonoka kwemwoyo.
Izvi zvinogona kukonzerwa nekurwara kwepamuviri kana kuti kupindura kurwadziwa, kutya kana kushungurudzika kamwe. Vamwe vanhu vanonyanya kutarisana nevasovagal reflex, uye ropa ravo rinoshandiswa uye kuchinja kwemwoyo kunogona kukonzera kurasikirwa kwekuziva - chiitiko chinonzi " vasovagal syncope ."
Kuwedzerwa kushandiswa kweve vagus nerve kunoonekwawo mune dzimwe hutano, kunyanya dysautonomias .
Kukurudzira vagus nerve kunogona kuva nemigumisiro yekurapa (zvakadai sokumisa zvikamu zvepraventricular tachycardia (SVT) kana kuti hiccups), uye inogona kubatsira vanachiremba kuti vaone mamwe marudzi emwoyo achin'un'una. Vagal stimulation inogona kuwanikwa nyore nyore kuburikidza nekushandisa nzira yeValsalva .
Ivo Vagus Nerve uye Moyo
Mushonga wekakodzero wakanaka unopa node ye sinus, uye kukurudzira kwayo kunogona kubudisa sinus bradycardia . Nhengo yevasusiti yakasara inopa iyo node yeAV, uye kukurudzirwa kwayo kunogona kubudisa maitiro e mwoyo block . Iko kuburikidza nokubudisa nguva yakareba mwoyo yekuti block yeValsalva inogona kupedza marudzi mazhinji eSVT.
Nhengo Yevagus In Medical Therapy kana VNS Therapy
Nemhaka yekuti vagus nerve ine mabasa akawanda anokosha, sayenzi yezvokurapa yakave ichifarira mumakumi emakore mubasa rekushandisa vagus nerve stimulation, kana vagus nerve blocking, murapi yehutano.
Kwemazana emakore, vagotomy nzira (kudzvora vagus nerve) yakanga iri iyo nzira yepamusoro yekurapa kwepectic ulcer chirwere , sezvo ichi chaiva nzira yekuderedza chiyero chepptic acid inogadzirwa nedumbu. Zvisinei, vagotomy yakave nemigumisiro yakawanda yakaipa, uye nekuwanika kwehutano huri nani iye zvino yava kunyanya kushandiswa.
Nhasi, kune chido chakakura pakushandisa magetsi ekugadzirisa (zvikuru, kugadziriswa pacemakers ) kuti zvive nyore kukurudzira vagus nerve mukuedza kubata zvirwere zvakasiyana-siyana zveutano. Zvirongwa zvakadaro (zvinotaurwa pamusoro pese se vagus nerve stimulating devices, kana VNS zvigadzirwa) zvakashandiswa kubudirira kuporesa vanhu vane hosha yakaoma iyo inopesana nemishonga inodhaka.
VNS therapy inoshandiswawo dzimwe nguva kuratidzira kusaora mwoyo.
Nokuti kana iwe une nyundo zvinhu zvose zvinoratidzika semisungo, makambani anoita VNS maitiro ari kuongorora kushandiswa kwavo mune dzimwe mimwe mamiriro ezvinhu anosanganisira kuwedzera kwehutano , migraines , tinnitus , fibromyalgia uye kuora kurasikirwa.
Iko kune zvivimbiso mune zvinyorwa zvakadaro zveVNS. Asi zvakadaro, simba rechokwadi reVNS richabuda apo iyo hype inotsiviwa nehutano hwekliniki uchapupu.
