Ukuthimula kuyinto esicabanga ukuthi siyayazi sonke, okuyinto ejwayelekile kepha kungaba wuphawu lwezifo ezahlukahlukene. Kungukuxoshwa komoya emaphashini ngekhala nangomlomo, imvamisa kuphendula ukucasuka komcibisholo wamakhala.

Le yi-reflex yokuzivikela: ivumela izinhlayiya, izinto ezicasulayo noma amagciwane angadala ukuthi ukutheleleka kuxoshwe emakhaleni.

Njengoba kuvamile njengoba kunjalo, kuncane okusaziwa ngokuthimula. Kufundwe kancane futhi izindlela ezisebenza ngayo aziqondakali ngokuphelele.

Ukuthimula kaningi kwenzeka ekuphenduleni ukucasuka kwe-mucosa yamakhala, okubangelwa ubukhona bothuli, ngokwesibonelo.

Kungabuye kubangelwe, kwabanye abantu, ngokuchayeka elangeni noma ekukhanyeni okukhanyayo: lena yi-reflex photo-sternutatory. Lokhu kungakhathaza cishe ikota yabantu.

Ezinye izimo zingadala ukuthimula noma isifiso sokuthimula, kuya ngomuntu, njengokuthola isisu esigcwele, ukudla ukudla okuthile, ukuba ne-orgasm, njll.

Ukungezwani komzimba, ngakho-ke ukuchayeka kuma-allergener, kuyaziwa ukuthi kubangela ukuqhuma kokuthimula, ngaphezu kwezinye i-rhinitis noma izimpawu zamehlo ezinamanzi. Ama-Allergener enza i-mucosa mucosa icindezeleke kakhulu, ngakho-ke iyashesha ukucasuka.

Ekugcineni, izifo ezifana nesifo sokuwa noma isilonda se-postero-inferior cerebellar artery kwesinye isikhathi kungaholela ekuthimuleni okungafuneki.

Kwenzekani uma uthimula? Izindlela aziqondakali ngokuphelele, kepha kuyaziwa ukuthi i-mucosa yamakhala, lapho icasukile, idlulisela imininingwane kwi-nerve trigeminal, eyenza i-nucleus ye-trigeminal isebenze ebuchosheni. Yilesi sikhungo "esilawula" ukuthimula kwemisipha yesithwathwa, phakathi kwabanye. Ngakho-ke kuyisimo sokuzizwa uvalo.

Le reflex ifaka isigaba sokuphefumulelwa esilandelwa isigaba sokuphelelwa yisikhathi, lapho umoya uxoshwa khona ngejubane elilinganiselwa ku-150 km / h. Ulwanga nolwe-glottis baqondisa umoya obheke ekhaleni, ukuqinisekisa “ukuhlanzwa” kwawo. Ukuthimula okukodwa kungaxosha amagciwane ayikhulu kanye namagciwane emakhaleni.

Isikhathi esiningi, ayikho imiphumela: ukuthimula kuyindlela evamile nenempilo.

Kodwa-ke, kuye kwaba nemibiko yokulimala okuhlobene nodlame lokuthimula, kufaka phakathi ukuphuka kobambo, ukuqala kwe-infarction ye-myocardial noma ukucindezelwa kwemizwa ye-sciatic.

Ikakhulukazi lapho ukuthimula kulandelana, ngokwesibonelo uma kwenzeka kukhona ukungezwani komzimba, lapho kungacasula khona.

Kungcono ukulinda ukuthimula kudlule. Uma kunesidingo ngesikhathi esingalungile, ungazama ukucindezela ichopho lekhala lakho ngenkathi ushaya ngomlomo wakho, ukuze nje uzame "ukuvimba" i-reflex.

Ekugcineni, uma ukuthimula kwenzeka kaningi kakhulu, kungcono ukubonisana ukuze uthole imbangela. Izindlela zokwelapha ze-antihistamine zinganciphisa izimpawu zokungezwani komzimba, isibonelo. Busisiwe !
