Inani lenqubo yesifo emzimbeni womuntu likhulu kakhulu. Phela, kubhekene nobuhlobo phakathi komzimba ngamunye, izinhlelo zomzimba kanye nokusebenza komzimba womuntu. Umsebenzi wesistimu yezinzwa kubangelwa okulandelayo:
- Ukusungula nokusungula ubuhlobo phakathi kwezwe langaphandle (imvelo yomphakathi kanye nemvelo) nomzimba.
- Ukungena kwe-anatomic kuzo zonke izakhi nezicubu.
- Ukudidiyelwa kwenqubo ngayinye ye-metabolic eyenzeka ngaphakathi komzimba.
- Ukuphatha imisebenzi yezinsiza kanye nezinhlelo zezinhlaka, ukuzihlanganisa zibe munye.
Ukubaluleka kwesimiso sezinzwa zomuntu
Ukuze ubone isisindo sangaphakathi nangaphandle, isimiso sezinzwa sinezakhiwo zengqondo kulabahlaziyi. Lezi zakhiwo zihlanganisa amadivaysi athile akwazi ukuthola ulwazi:
- Ama-Proprioceptors. Baqoqa lonke ulwazi oluphathelene nesimo samasipha, amathambo, ama-fascia, amalunga, ukutholakala kwe-fiber.
- Ama-Exteroreceptors. Zitholakala esikhunjeni somuntu, izitho zengqondo, izibungu zamangcwaba. Uyakwazi ukubona izinto ezicasulayo ezitholakala emvelweni ozungezile.
- Ama-interreceptors. Zitholakala ezicukweni nasezimbilini zangaphakathi. Uxhomeke ekuboneni ushintsho lwezinto eziphilayo olutholakala emvelweni wangaphandle.
Ukubaluleka okuyinhloko nemisebenzi yesistimu yezinzwa
Kubalulekile ukuphawula ukuthi ngosizo lwesimiso sezinzwa, ukuqonda, ukuhlaziywa kolwazi mayelana nokucasuka okuvela ezweni langaphandle nezitho zangaphakathi kwenziwa. Futhi unesibopho sokuphendula kulezi zinkinga.
Umzimba wesintu, ubuhle obuvumelana nokushintsha kwezwe elizungezile, kubonakala, ngokuyinhloko ngenxa yokusebenzisana kwezinqubo zokuziphatha ezihlambalaza kanye nabesaba.
Imisebenzi esemqoka ihlanganisa:
- Incazelo yempilo yengqondo nemisebenzi yabantu, okuyisisekelo sokuphila kwakhe komphakathi.
- Umthethonqubo wemisebenzi ebalulekile yezitho zomzimba, izinhlelo zabo, izicubu.
- Ukuhlanganiswa kwemvelo, ukuhlanganiswa kwayo ibe yinye.
- Ukugcina ubuhlobo bomzimba wonke nemvelo. Endabeni yokushintsha izimo zemvelo, isimiso sezinzwa senza izinguquko kulezi zimo.
Ukuze uqonde ngokunembile ukubaluleka kwesimiso sezinzwa, kubalulekile ukuqonda imisho kanye nemisebenzi esemqoka yesistimu yezinzwa eziphakathi nendawo.
Ukubaluleka kwesistimu yezinzwa eziphakathi
Yingxenye eyinhloko yesimiso sezinzwa zomuntu nezilwane. Umsebenzi walo oyinhloko ukugcwaliseka kwezinga elihlukile lokuziphendulela kwezenzo ezibizwa ngokuthi i-reflexes.
Ngenxa yomsebenzi we-CNS, ubuchopho buyakwazi ukukhombisa ngokucacile izinguquko ezweni elizwe langaphandle. Ukubaluleka kwalo kubangelwa ukuthi lilawula zonke izinhlobo zokuziphendulela, liyakwazi ukubona izinto ezitholwa zombili ezitholakala ngaphakathi nasezizweni zangaphandle.
Ukubaluleka kwesistimu yezinzwa ze-peripheral
I-PNS ixhuma i-CNS ngamalungu nezitho. I-neurons yayo itholakala ngaphesheya kwesistimu yezinzwa zomphakathi - intambo yomgogodla nobuchopho.
Akuvikelwe ngamathambo, okungaholela ekulimaleni komonakalo noma ezinobuthi obuyingozi.
Ngenxa yokusebenza kahle kwe-PNC, ukuhlanganiswa kokunyakaza komzimba kuyahambisana. Lolu hlelo lubhekene nokulawula okuqaphele kwezenzo zenyama yonke. Unesibopho sokuphendula ezimweni ezicindezelayo nasengozini. Ukwandisa isilinganiso senhliziyo. Uma kwenzeka injabulo, yandisa izinga le-adrenaline.
Kubalulekile ukukhumbula ukuthi umuntu kufanele njalo anakekele impilo yakhe. Emva kwakho konke, lapho umuntu ehola impilo enempilo, enamathela embusweni oqondile wosuku, akayikugijima umzimba wakhe nganoma iyiphi indlela, ngakho-ke uhlala ephilile.
