Uhlelo lwezinzwa luhlukaniswe ohlelweni lwangaphakathi nolunye lwesisindo. Uhlelo oluphakathi luhlanganisa intambo yomgogodla kanye nenhloko, lapho izintambo zezinzwa zihlukana kuwo wonke umzimba womuntu. Bamele isimiso sezinzwa zomzimba. Ixhuma ubuchopho emahlathini, emisipha, nakwezingxenye zomqondo.
Imisebenzi yesimiso sezinzwa zomuntu
Umsebenzi oyinhloko wesimiso sezinzwa ukufakwa komthelela emzimbeni ovela ngaphandle, kuhambisane nokuphendula okuguquguqukayo komzimba womuntu. Ubuchopho buqukethe i-trunk kanye ne-forebrain. Umnyango ngamunye wobuchopho unesibopho sokwenza imisebenzi ethile. Cabanga ngemisebenzi yesistimu ye-central central:
- Njengoba i-forebrain ihlukaniswe yaba yiyokugcina futhi ephakathi, ngakho-ke, yilowo nalowo uthatha imisebenzi ethile. Ngakho-ke, i-hypothalamus, i-thalamus ne-limbic system iyingxenye yesikhashana. Owokuqala uyisisekelo sezidingo ezibalulekile (libido, indlala), imizwelo. I-thalamus yenza inqubo eyinhloko yokwaziswa, ukuhlunga kwayo. Uhlelo lwe-limbic lubophezele ekuziphatheni ngokomzwelo komuntu ngamunye.
- Isakhiwo salesi simiso sezinzwa sifaka amaseli okuthiwa i-neuroglia. Benza umsebenzi osekelayo, bahlanganyele ekusetshenzisweni kwamathambo wesistimu yezinzwa.
- Emthonjeni womgogodla kukhona into emhlophe edala indlela. Baxhuma ubuchopho obuningi bokuqala nobuchopho, izingxenye ezihlukene zobuchopho komunye nomunye. Izindlela zenza umsebenzi oqhutshwayo, osebenza kahle.
- Abahlaziyi badlala indima yababonisi ekuqaphelisweni komuntu ezweni langaphandle.
- Umsebenzi we-cortex ye-cerebral ungumsebenzi ophakeme wezinzwa futhi wenza umsebenzi obhekene nesimo se-reflex.
Imisebenzi esemqoka yesistimu yezinzwa zomphakathi yindlela yokusebenzisa ukuphendula okulula nokuyinkimbinkimbi, okubizwa ngokuthi i-reflexes.
I-CNS enezitho nezitho zixhuma uhlelo lwezinzwa zomzimba. Akuvikelwe ngamathambo, okusho ukuthi kungadalulwa kwezidakamizwa kanye nokulimala komshini.Imisebenzi yesistimu yezinzwa ze-périphher
- I-PNS ihlukaniswe ibe yi-vegetative ne-somatic, ngayinye yayo eyenza imisebenzi ethile. Uhlelo lwesimiso se-somatic lubhekene nokuhlanganiswa kwezinyathelo nokuthola isenzo esivela ezweni langaphandle. Ilawula imisebenzi elawula ukuqonda komuntu.
- I-vegetative nayo yenza umsebenzi wokuzivikela lapho kwenzeka ukuthi ingozi noma isimo esicindezelayo sesiseduze. Ubhekene nokucindezelwa kwegazi kanye ne-pulse. Uma umuntu ekhathazekile, yena, ebhala umuzwa wokuthakazelisa, uphakamisa izinga le-adrenaline.
- Uhlelo lwe-parasympathetic, oluyingxenye yesimiso semifino, lwenza imisebenzi yaso uma umuntu ephumula. Unesibopho sokunciphisa abafundi, ukugqugquzelwa kwesistimu ye-genitourinary nokugaya.
Noma kunjalo, yimiphi imisebenzi isimiso sezinzwa esenzayo?
- Ukuthola ulwazi mayelana nezwe elizungeze umuntu kanye nesimo somzimba.
- Dlulisa lolu lwazi ebuchosheni.
- Ukulungiswa kwe-conscious
ukunyakaza. - Ukuxhumanisa nokulawulwa kwesigqi senhliziyo, izinga lokushisa, njll.
Ukuphulwa kwemisebenzi yesimiso sezinzwa
Ukuphulwa kwemisebenzi yayo kungabangela:
- Ukwehla kwesifungo (i-vertebrae ephiniwe).
- Ubuthi ngezinto ezinobuthi.
- Ukuphuza utshwala.
- Multiple sclerosis.
