Ixabiso lenkqubo yesifo emzimbeni womntu lukhulu. Emva koko, uxanduva lobudlelwane phakathi kwelungu ngalinye, iinkqubo zesebe kunye nokusebenza komzimba womntu. Umsebenzi wesistim se-nervous ubangelwa zilandelayo:
- Ukuseka nokuseka ubudlelwane phakathi kwehlabathi langaphandle (intlalo yoluntu kunye nemvelo) kunye nomzimba.
- I-Anatomic yokungena kuwo onke amalungu kunye nezicubu.
- Ulungelelaniso lwenkqubo nganye yemetrikhi eyenzeka ngaphakathi komzimba.
- Ukulawula imisebenzi yeefayili kunye neenkqubo zesebe, ukudibanisa kwelinye.
Ukubaluleka kwenkqubo yesantya yomntu
Ukuze uqikelele isistim sokungaphakathi nangaphandle, inkqubo ye-nervous inezakhiwo zengqondo kubahlalutyi. Ezi zakhiwo ziquka izixhobo ezithile ezikwazi ukuqonda ulwazi:
- Proprioceptors. Baqokelela yonke ingcaciso malunga nemeko yamathambo, amathambo, i-fascia, amajoyina, ubukho befiber.
- Zangaphandle. Zitholakala kwesikhumba somntu, izitho zengqondo, iimbumba ezinqabileyo. Unako ukuqonda izinto ezivuthayo ezifunyenweyo kwiindawo ezijikelezayo.
- Interreceptors. Zifumaneka kwizicubu kunye nezitho zangaphakathi. Uxanduva lokujonga iinguqulelo zezinto eziphilayo ezivela kwindawo yangaphandle.
Ukubaluleka okubalulekileyo kunye nemisebenzi yenkqubo yesantya
Kubalulekile ukuba uqaphele ukuba ngoncedo lwenkqubo yesifo, ukuqonda, ukuhlalutya ulwazi malunga neengxaki ezivela kwilizwe langaphandle kunye nezitho zangaphakathi zenziwa. Kwakhona unembopheleleko yokuphendula kwezi zizathu.
Umzimba womntu, ukulungelelaniswa kokutshintshelwa kweenguqu kwihlabathi elijikelezile, kuzaliseka, ngokuyinhloko ngenxa yokusebenzisana kweendlela zokuziphatha kunye neentlanzi.
Imisebenzi ephambili ibandakanya:
- Inkcazo yempilo yengqondo kunye nemisebenzi yabantu, eyona isiseko sobomi bayo.
- Ummiselo wemisebenzi ebalulekileyo yemizimba yezitho, iinkqubo zawo, iifom.
- Ukuhlanganiswa kwendalo, ukuhlanganiswa kwayo ibe yinye.
- Ukugcina ubudlelwane bomhlaba wonke kunye nendalo. Kwimeko yokutshintsha iimeko zemeko, inkqubo ye-nervous yenza izilungiso kule miqathango.
Ukuze uqonde ngokuchanekileyo ukubaluleka kwenkqubo yesantya, kuyimfuneko ukuqonda intsingiselo kunye nemisebenzi ephambili yenkqubo ye-nervous central kunye ne-peripheral.
Ukubaluleka kwenkqubo yesantya ephakathi
Yona nxalenye ebalulekileyo yenkqubo yeentlungu zabantu kunye nezilwanyana. Umsebenzi walo oyintloko kukufezekiswa kwendlela eyahlukileyo yokuphendula ngendlela ebizwa ngokuba yi-reflexes.
Ngombulelo kumsebenzi we-CNS, ubuchopho buyakwazi ukubonakalisa ngokucacileyo utshintsho kwihlabathi elingaziwayo langaphandle. Ukubaluleka kwayo kubangelwa kukuba lilawula zonke iintlobo zeengcamango, ziyakwazi ukubona izinto ezifunyenwe zivela kwizitho zangaphakathi nakwihlabathi langaphandle.
Ukubaluleka kwenkqubo ye-nervous system
I-PNS idibanisa i-CNS ngamalungu kunye nezitho. I-neurons yayo ilapha ngaphaya kwenkqubo ye-nervous central - intambo yomgogodla kunye nengqondo.
Akukhuselekanga ngamathambo, oku kungakhokelela ekulimaleni komonakalo okanye kwingozi yeexin.
Ngenxa yokusebenza kakuhle kwe-PNC, ukulungelelaniswa kwamanyathelo omzimba kuyahambisana. Le nkqubo inoxanduva lokulawula ukuqonda kwezenzo zendalo yonke. Uxanduva lokuphendula kwiimeko ezixinzelelekileyo kunye nobungozi. Ukwandisa izinga lentliziyo. Xa kunomdla, ukwandisa izinga le-adrenaline.
Kubalulekile ukuba ukhumbule ukuba umntu kufuneka ahlale enyamekela impilo yakhe. Emva koko, xa umntu ekhokelela kwimpilo enempilo, unamathele kulawulo oluchanekileyo lolo suku, akayikuwuthwala umzimba wakhe nangayiphi indlela, kwaye ke uhlala ephilile.
