I-peripheral nervous system

I-peripheral nervous system iqukethe imizwa, cranial ganglia spinal esisogwini inkambo yabo (ganglia). It uxhuma izibilini, isikhumba nemisipha isimiso sezinzwa esiyinhloko (CNS). Ngesisekelo nalokhu, peripheral nervous system kuyinto zezinhlobo ezimbili: autonomic futhi ukuphathwa kwabathintwayo. Lesi sakamuva ifomu labo emizweni ukuxhuma CNS kwemisipha, isikhumba kanye imisipha. Ukuze autonomic nervous system bangabanye labo emizweni ukuxhuma CNS ukuba izindlala, imithambo yegazi kanye izitho zangaphakathi.

Ezizwelayo yezinzwa kanye ukunyakaza siqukethe izinzwa emgogodleni. On the isikhumba, imisipha, nolwelwesi lwamafinyila, izitho zangaphakathi, imisipha wahlela ama-receptor. Lezi zokwakheka sebeqala Imicu yotshani ebucayi. Bathumela amasignali eziqukethe idatha mayelana nesimo umzimba kanye imvelo ezungeze e isimiso sezinzwa esiyinhloko. Ngu motor Imicu yotshani, Ngakolunye uhlangothi, ithumela CNS izitsha, izitho zangaphakathi, imisipha amasignali. Ngakho-ke elawula umzimba osabela ngayo ezintweni ezithile ziqondakala receptor.

Nambili namabhuzu nezinzwa cranial elihlobene ne ingqondo. Siyabonga kubo, ahlale ebucayi ingaphakathi acinene nomlomo, nomphimbo, ukuluma kwamehlo, isikhumba ibala. Zinikeza ukuxhumana yonke sezinzwa uhlelo receptor, ukuzwa, ukunambitha, ukubona kanye nephunga. Lokhu kuthathwa imicu ukuphathwa kwabathintwayo, nokulawula autonomic ukusebenza nezindlala (futhi lacrimal kanye salivary), zihilelekile kulo inqubo emishinini yokuphefumula, inhliziyo futhi isimiso sokugaya ukudla bungene.

I-peripheral nervous system kufanele kube kakhulu aqine CNS ukuletha motor noma sezinzwa amaza. Kusemqoka ukuqinisekisa ukuxhumana okusheshayo phakathi kobuchopho ubuchopho, umgogodla futhi receptor.

I-peripheral nervous system umuntu echayeke inani elikhulu izifo. Izizathu ezihlukahlukene zabo ebanzi: ubuthi, ukuhlukumezeka, nezinzwa babancwebe, izinkinga kwegazi noma ukuvuvukala umzimba. inhlanganisela yezici ngokuvamile atholakala.

Ukwahlukaniswa lezi zifo luncike lokho kuyisabelo ethintekile neuropathy isimiso sezinzwa. Uma kuwukuthi ukuphela kwalesi emgogodleni babe avuvukele, sciatica kwenzeka uma abathintekayo emsipheni plexus - pleurisy. Izimpawu ezivame kakhulu peripheral neuropathy livela eziyinkimbinkimbi. Ngakho, uma unenkinga ngentambo kwesigaba umgogodla, lapho plexites, neuritis, radiculitis. Basuke ephelezelwa ubuhlungu bebheke iziqu kwenzwa kwehle isikhumba ukuzwela kule ndawo, kukhona ubuthaka imisipha, kancane kancane yoma. I ukubonakaliswa okufanayo, ushintsha kuphela indawo lesion.

Kodwa uma umonakalo yanoma yiziphi imizwa cranial siyenzeka Umbono kahle ebukwayo, imisindo nephunga, kodwa akukho ubuhlungu, ukulahlekelwa sezinzwa. I-peripheral kwemizwa uhlelo eziningana iminyango, ukuze ukwelapha izifo incike izizathu oholele kubo, futhi obekukhona lawushaya umhlaba. Ngemva Ukuhlolisisa udokotela ekunika imithi, inqubo fizioterapevtichekie. Kuye kobukhulu isifo isiguli ukunikela ukuhlala esibhedlela noma emtholampilo suku. Ukuhlinzwa kusebenza kuphela uma ukudabuka we izinzwa neuropathy okubangelwa ukuhlukumezeka.

Izifo lokuvikela kuhambisana siphephe uma usebenza nge ubuthi. Gwema hypothermia. Sikashukela ukuxwayisa polyneuritis sikashukela kufanele ayevame ukuvakashela udokotela futhi uthathe indawo ekhethekile izifo. Ikakhulukazi ukungenwa ukunqoba lesi simiso, ababhemayo yotshwala.
