Izinhlaka touch - a receptor ekhethekile, okuyinto zitholakala esikhumbeni, imisipha, nemisipha, amalunga, nolwelwesi lwamafinyila. Ngalezi amadivayisi Bebona umzimba womuntu aphendvule umphumela ohlangene ezishukumisa ezizungezile: ubuhlungu, izinga lokushisa kanye lokukhanda. Esikhumbeni izinhlaka touch kuthiwa Ukuboshelwa zisakazwe, isibonelo, i-zezandla, iminwe, izindebe, umthondo futhi amathe abo lilikhulu, ngakho kulezi zindawo sizwele nezici ezihlukahlukene kwemvelo. Ngenxa yalesi isegazini ikhono abantu kungavimbela umonakalo sina futhi ukulimala emzimbeni.
Njengoba izinhlaka touch umsebenzi?
receptor Eqaphela ukhonza ezinzwa amaza e cortex we ama- cerebral ikhanda, lapho nozwela analyzers isikhumba zitholakala. Njengoba umzimba omkhulu touch - lesikhumba, ngisho nethonya kancane ku zayo lifundwa futhi ukucutshungulwa kolwazi ekhanda lami evumela umuntu ukuba asabela ngokushesha imbangela yokucasuka nekugwema ke ngesikhathi.
ukusabela ubuhlungu
Ubuhlungu, isibonelo, uyakwazi ukubona ebucayi khulula kwalapho ukuthi zingene ukushuba we epidermis. Lezi receptor ukuphendula ngisho uyithinta kancane noma umoya ovunguzayo, ikakhulukazi izimpande izinwele. Ngaphezu kwalokho, epidermis aqukethe Merkel emangqamuzaneni okuthiwa abe nobuhlobo obuseduze izinzwa olubucayi futhi ziyakwazi ukukhiqiza izinto ezikhethekile ukufukula omzimba wonke umzimba.
Umbono izici mechanical
izitho Okuthintekayo, obhekene impendulo ezintweni mechanical, ngokuthi Meissner corpuscles. Basuke ise ungqimba papillary kwesikhumba yeminwe, isibunu zangaphandle, izindebe nezinkophe. Receptor ingcindezi aphume ashone Vater-Pacini corpuscles kokuba simise ipuleti. Njengomthetho, ukuthi akuphi ku izingqimba ezijulile ongama neminwe, zangasese kanye izitho zangaphakathi kanye ezindongeni esinyeni. On ukufuduka kwesikhumba, kanye nokukhama zabo ngokweqile basabela Ruffini corpuscles, ekuqongeleleni okuyinto nasemkhakheni izingqimba ezijulile le epidermis sezinyawo. Krause ekupheleni isibani ukuvumela umuntu ukuba baphendule lo ezishukumisa we conjunctiva, ulimi kanye zangasese zangaphandle. Kuyinto ngenxa lezi ezenza umuntu angase abe nomuzwa nomzimba angaphandle emehlweni, futhi ngendlela esifike ngesikhathi ukuqeda ke, kanjalo uvimbele ukudala ezinye ukucasuka olwengeziwe.
Izinhlaka yokuhogela nokuthinta ephezulu abaluleke kakhulu ngenxa yokuphila evamile yabantu, naphezu kweqiniso lokuthi la mangqamuzana odorant ukuthuthukisa kuphela emva kokuzalwa. Ngokungangabazeki, izilwane zingcono kakhulu ukwazi ukusebenzisa amakhono ngenxa ukuthi ngezinye izikhathi abanazo. Abaningi bakholelwa ukuthi lo msebenzi ayibalulekile ngoba umuntu, kodwa uzizwa iphunga, singazibona ingozi esondelayo emkhathizwe eside ngaphambi kokuba livele. Ngaphezu kwalokho, nice kamnandi izinto kungaba ngokuphawulekayo kuthinta indlela esiqonda ngayo okuthile noma nje ekhanyisa kwemizwa. Kule singaphetha ngokuthi imvelo ngomusa uye wasinikeza amakhono amangalisayo ezisisiza ukuba siphile futhi nihlanganyele.
