The tsitsi tsinga uye ayo mabasa

The autonomic tsinga, rinonziwo autonomic, ane zviumbu anoverengeka kana zvikamu. Mumwe wavo - aimunzwira tsitsi tsinga. Weboka muzvikamu inobva chadzo uye morphological maitiro. Chimwe subspecies ndiyo parasympathetic tsinga.

Muupenyu munhu mupenyu muviri tsinga anoita zvakasiyana-siyana zvinoratidza kuti zvinoita refu kwazvo kukosha. Roga, mugadziriro yakaoma uye ine madhipatimendi wandei uye subspecies, chimwe nechimwe zvinotora nezvezvimwe mabasa. Most kunakidza ndechokuti kekutanga zvakadai chinhu chimwe sezvo tsitsi tsinga akaonekwa 1732. Pakutanga, shoko rakashandiswa kutsanangura yose autonomic tsinga. Asi sezvo vaunganidza zivo masayendisiti, vakaziva kuti pano nhema munhu yakakura kupfuura layer saka pfungwa iyi vakatanga kureva subspecies mumwe chete.

Kana isu funga chaizvo tsika, inowanikwa kuti tsitsi tsinga anoita zvikuru dzinonakidza mabasa nokuti muviri - hazvina basa kuti kudyiwa zvinhu, uyewo kuunganidza mauto ari zvashata ezvinhu. Kana zvava kudikanwa, aimunzwira tsitsi hurongwa kunowedzera simba rakawanda, saka muviri aigona kuramba ichishanda kuitiswa uye mabasa ayo. Patinotaura pamusoro mikana zvakavanzika uye pfuma, isu kureva chaizvo kuti. On sei negadziriro achagadzirisa nayo, achavaponesa ezvinhu muviri.

Zvisinei, izvi zvose ane simba mupfungwa muviri, refu kudaro nzira iyi, harigoni kushanda. Pano unosvika parasympathetic ino, iyo ine basa zviwanikwa uye nokudzorerwa kuwanda kwavo, saka kuti gare gare murume aikwanisa kuita zvakafanana mabasa, asi zvinhu aro haungoratidzwi. The tsitsi uye parasympathetic tsinga kubvumira dzose kushanda kunoita muviri ezvinhu akasiyana. Vanoshanda inokosha uye akaramba mukwanisi mumwe.

Zvaiitwa tsitsi hurongwa

Sezvambotaurwa, kune tsitsi gadziriro iri kusashanda zvizere zvinokangaidza. Mune mamwe mashoko inonzi reactive tsitsi tsinga, nokuti vanofanira kupa zvimwe muviri achipindura ezvinhu, aumba kubva kunze.

Panguva ino mune adrenal shwanu anotanga kubudisa adrenaline, inova huru nenhumbi kuti anobvumira vanhu kuti nani uye sei zvinokangaidza nokukurumidza. Zvisinei, zvakadarowo kunogona kuitika panguva yechiitwa, kana nokuda pakabudiswa adrenaline munhu anotanga kurarama nayo nani. adrenaline secretion runogonesa Zvakaitwa tsitsi ino, iyo anotanga "anopa" pfuma nokuda kwakawedzera simba rakawanda nokuti chete adrenaline kunomutsa siyana nadzo uye pfungwa, asi yorega varidzi upfumi.

Mugumisiro muviri mukuru zvakakwana, nokuti ipapo munhu kushushikana kuneta, simba, uye zvichingodaro, zvichienderana refu sei akaita adrenaline kushanda uye kuti tsitsi gadziriro refu kupedzera zvinhu kuti vatsigire basa muviri panguva iyoyo chechetere.
