• Anatomy yeiyo vagus nerve
• Mabasa makuru
• Kuchinja kweiyo vagus nerve

Iyo vagus nerve, inozivikanwawo seye pneumogastric nerve, itsinga inomhanya kubva kuuropi ichienda padumbu, uye munzira yayo, inopa matavi akati wandei ayo anokanganisa akasiyana emumuromo wechibereko, thoracic uye nhengo dzemudumbu, ane manzwiro uye mota mashandiro, kuve kwakakosha kune chengetedzo yemabasa akakosha, senge kurova kwemoyo uye arterial mutemo, semuenzaniso

Iyo peya ye vagus nerves, iri padivi rega remuviri, ndiyo yegumi yegumi yeiyo yakazara e12 cranial majoini ayo anobatanidza uropi kumuviri. Sezvo tsinga dzenyonganyonga dzichinzi manhamba echiRoma, iyo vagus nerve inonziwo X peya, uye inoonekwa seyakarebesa mutsipa wetsinga.

Zvimwe zvinokonzeresa kune vagus nerve, inokonzerwa nekuzvidya mwoyo, kutya, kurwadziwa, shanduko yetembiricha kana kungomira kwenguva refu, zvinogona kukonzera iyo inonzi vasovagal syncope, umo munhu anogona kusangana nedzungu rakanyanya kana kupera simba, seiyi tsinga zvinogona kukonzera kudonha mukurova kwemoyo uye kuwedzerwa kweropa. Nzwisisa chinonzi vasovagal syncope uye maitiro ekuirapa.

Kwakatangira iyo vagus nerve

Iyo vagus nerve ndiyo yakakurisa tsinga uye inotangira kuseri kwegirobhu remuzongoza, chimiro chehuropi chinobatanidza huropi netambo yemusana, uye chinosiya dehenya kuburikidza nekuvhura kunonzi jugular foramen, kuchidzika kuburikidza nemutsipa uye chipfuva kusvika icho inoperera mudumbu.

Munguva yekufamba kweiyo vagus nerve, inoisa mukati iyo pharynx, larynx, moyo uye dzimwe nhengo, uye iri kuburikidza nazvo iyo iyo uropi inoona kuti idzi nhengo dzakadii uye inodzora akati wandei emabasa avo.

Mabasa makuru

Mamwe emabasa makuru eiyo vagus nerve anosanganisira:

• Reflexes yekukosora, kumedza uye kurutsa;
• Kupesana kwetambo dzezwi kugadzirwa kwenzwi;
• Kudzora kwekudzora moyo;
• Yakadzikira kurova kwemoyo;
• Kufema kwekufamba uye bronchial constriction;
• Kufambisa esophageal uye ura kufamba, uye kuwedzera gastric secretion;
• Kugadzira ziya.

Uye zvakare, iyo vagus nerve inogoverana mamwe emabasa ayo neiyo glossopharyngeal nerve (IX pair), kunyanya mudunhu remutsipa, kuve nekukonzeresa kwekunzwa kwekunzwa, uko vagus nerve inowirirana zvakanyanya nekuvava uye glossopharyngeal nekuvavira kunorwadza.

Kuchinja kweiyo vagus nerve

Iyo vagus nerve palsy inogona kukonzeresa mukumedza, hoarseness, kunetseka mukutaura, kupunzika mune mhasuru dzeiyo pharynx uye larynx, uye shanduko mukumanikidza kweropa uye kurova kwemoyo. Uku kupora mitezo kunogona kuitika nekuda kwekukuvara, kukuvara mukuvhiya, kumanikidzwa nemamota kana mamwe maronda syndromes.

Uye zvakare, pane mamiriro ezvinhu anokonzeresa kukurudzira kweiyo vagus nerve, ichigadzira mamiriro anonzi vagal syncope kana kupera simba. Izvo zvinowanzoitika kune vechidiki vanhu uye zvinokonzerwa nekudzikiswa kwemoyo uye kuwedzerwa kweropa, nekuda kwekushayikwa kwe oxygen muuropi, zvichikonzera kufenda. Ona zvekuita kana iwe uchipfuura.

Vagal syncope inogona kukonzerwa ne:

• Kuratidzira kupisa;
• Manzwiro akasimba, senge kutsamwa;
• Kuramba wakamira kwenguva refu;
• Temperature kuchinja;
• Kumedza zvikafu zvakakura kwazvo;
• Kuva pakakwirira pakakwirira;
• Inzwa nzara, kurwadziwa, kana zvimwe zvisingafadzi zviitiko.

Iko kukurudzira kweiyo vagus nerve kunogona zvakare kuitwa kuburikidza nemasaji parutivi rwemutsipa. Dzimwe nguva vagal maneuver inoitwa navanachiremba mune yechimbichimbi kudzora yemoyo arrhythmia.
