Nzira yemagetsi ndiyo yemukati yekutaurirana system. Yakagadzirwa nemasero mazhinji emuviri emuviri. Masero etsinga anotora ruzivo kuburikidza nepfungwa dzemuviri: kubata, kuravira, kunhuwidza, kuona, uye kurira. Uropi hunodudzira idzi pfungwa dzekunzwa kuti unzwisise zviri kuitika kunze nekunze kwemuviri. Izvi zvinobvumidza munhu kuti ashandise muviri wake kudyidzana nharaunda yavo yakapoterera uye kudzora mashandiro emuviri wavo.

Iyo tsinga system yakaoma kwazvo. Tinovimba nayo mazuva ese kutibatsira kuti tigare takagwinya uye takachengeteka. Sei tichifanira kukoshesa hurongwa hwedu hwemitsipa? Verenga izvi gumi nezviviri zvinonakidza uye iwe uchazoziva nei.

1. Muviri une mabhirioni emaseru etsinga

Muviri wemunhu wese une mabhirioni emaseru etsinga (neurons). Iko kune anosvika mabhirioni zana muuropi uye mamirioni gumi nemakumi mashanu neshanu musipinha. Iyo neurons yemuviri inotora uye inotumira magetsi nemagetsi emakemikari (magetsi emagetsi) kune mamwe mauroni.

2. MaNeuron akagadzirwa nezvikamu zvitatu

MaNeuronin anogamuchira masaini mune pfupi kanyena-kunge chikamu chinonzi dendrite, uye kutumira masigine kune mamwe maNeuron ane yakareba tambo-yakaita chikamu chinonzi axon. Demo rinogona kusvika pamamita kureba.

Mune mamwe manyuroni, maazon akafukidzwa netaundi rakatetepa remafuta anonzi myelin, anoita seanodzivirira. Inobatsira kufambisa tsinga maseru, kana zvimiro, pasi peaxon refu. Chikamu chikuru cheeuroni chinonzi muviri wesero. Iine zvese zvakakosha zvikamu zvechitokisi zvinotendera kuti zvishande nemazvo.

3. MaNeuroni anogona kutaridzika akasiyana kubva kune mumwe

MaNeuron anouya akasiyana maumbirwo uye saizi zvinoenderana nekwavari mumuviri uye nezvavanorongedzerwa kuti vaite. Sensory neurons ine dendrites kumativi ese maviri uye akabatana nerefu axon ine chitunha chemuviri pakati. Ma mota neurons ane sero muviri kune rimwe divi uye dendrites kune rimwe divi, iine refu axon iri pakati.

4. MaNeuroni akarongwa kuti aite zvinhu zvakasiyana

Kune mhando ina dzeeuroni:

• Kunzwa: Sensory neurons inounza masaini emagetsi kubva kunhengo dzekunze dzemuviri - {textend} gland, mhasuru, uye ganda - {textend} muCNS.
• Motokari: Mota neurons inotakura zviratidzo kubva kuCNS kuenda kune ekunze mativi emuviri.
• Vanogamuchira: Receptor neurons inonzwisisa nharaunda (mwenje, ruzha, kubata, uye makemikari) zvakakukomberedza uye nekuzvishandura kuita simba remagetsi remagetsi rinotumirwa nema sensory neurons.
• Interneurons: Interneurons inotumira mameseji kubva kune imwe neuron kuenda kune imwe.

5. Pane zvikamu zviviri zvetsinga

Sisitimu yemunhu yekutyaira yakakamurwa kuita zvikamu zviviri. Ivo vanosiyaniswa nenzvimbo yavo mumuviri uye vanosanganisira yepakati yetsinga system (CNS) uye yekumusoro huta tsinga (PNS).

Iyo CNS iri mune dehenya uye vertebral canal yemuzongoza. Inosanganisira tsinga dziri muuropi uye musana. Tsinga dzese dzakasara mune mamwe mativi emuviri chikamu chePNS.

6. Kune mhando mbiri dzetsinga dzeshungu

Muviri wemunhu wese une CNS uye PNS. Asi zvakare ine yekuzvidira uye isingazvipire masystem masisitimu.Iyo yemuviri yekuzvidira (somatic) huta hwehurongwa hunodzora zvinhu izvo munhu anoziva uye anogona kuzvidzora achiziva, sekufambisa musoro wavo, maoko, makumbo, kana zvimwe zvikamu zvemuviri.

Izvo zvemuviri zvisingabvumirwe (zvinomera kana otomatiki) hunyanzvi hunodzora maitiro mumuviri izvo munhu asingazivi kuzvidzora. Iyo inogara ichishanda uye inodzora kurova kwemoyo wemunhu, kufema, metabolism, pakati peimwe miitiro yakakomba yemuviri.

7. Iyo yekusazvipira system yakaputsika kuita zvikamu zvitatu

Iyo CNS nePNS zvese zvinosanganisira zvekuzvidira uye zvisina basa zvikamu. Izvi zvikamu zvakabatanidzwa muCNS, asi kwete muPNS, uko zvinowanzoitika munzvimbo dzakasiyana dzemuviri. Chikamu chekuzvipira chePNS chinosanganisira tsitsi, parasympathetic, uye enteric nervous system.

8. Muviri une hurongwa hwekutyaira hwekugadzirira muviri kuita

Tsitsi dzinonzwira tsitsi dzinotaurira muviri kuti ugadzirire chiitiko chemuviri nepfungwa. Zvinokonzeresa kuti moyo urove zvakanyanya uye nekukurumidza uye kuvhura mafafitera ekufema kuri nyore. Inomisawo kugaya kwechinguva kuitira kuti muviri utarise pane chiito chinokurumidza.

9. Pane hunyanzvi hwekutonga muviri pakuzorora

Iyo parasympathetic nervous system inodzora mashandiro emuviri kana munhu azorora. Mimwe yemabasa ayo anosanganisira kukurudzira kugaya, kuita metabolism, uye kubatsira muviri kuzorora.

10. Pane tsinga inodzora ura

Muviri une hurongwa hwayo hwekutyaira hunongodzora ura. Iyo enteric nervous system inogadzirisa otomatiki kufamba kwese sechikamu chekugaya.

11. Sisitimu yako inogona kukanganiswa

izvozvi zviri kugadzira nzira dze "kubirira" muma immune system, ichiwana kugona kudzora maseru ehuropi nekupenya kwechiedza. Iwo maseru anogona kugadzirirwa kuita kune mwenje kuburikidza nemajini kuchinja.

Kubiridzira kunogona kubatsira masayendisiti kudzidza nezve mashandiro emapoka akasiyana emauroni. Vanogona kumisikidza maseru ehuropi akati wandei panguva imwe uye voona maitiro avo pamuviri.
