Dongosolo wachifundo mantha ndi ntchito zake

The autonomic mantha dongosolo, lomwe limatchedwanso autonomic, ali mayunitsi angapo kapena mbali. Mmodzi wa iwo - chifundo mantha dongosolo. Kudulidwa m'zigawo potengera makhalidwe zinchito ndi morphological. subspecies wina ndi mantha dongosolo parasympathetic.

Mu moyo wa moyo chamoyo mantha dongosolo amachita osiyanasiyana zinthu zimene zimapangitsa izo ndi kufunika kwambiri. Palokha, dongosolo ili yovuta komanso ali m'madipatimenti angapo ndipo subspecies, omwe amakhala ena mwa ntchito. Chidwi kwambiri ndi nthawi yoyamba chinthu choterocho monga mantha dongosolo wachifundo anaonekera mu 1732. Poyamba, mawu amenewa amagwiritsidwa ntchito kutanthauza lonse autonomic mantha dongosolo. Koma chidziwitso anasonkhanitsa asayansi, anazindikira kuti apa pagona wosanjikiza kwambiri ochulukirapo, choncho lingaliro ili anayamba kulozera kwa subspecies chimodzi chokha.

Ngati tikambirana mfundo zenizeni, izo zimapezeka kuti chifundo mantha dongosolo amagwira ntchito chidwi kwambiri kwa thupi - ndi udindo kumwa chuma, komanso yolimbikitsa ya mphamvu pa zochitika mwadzidzidzi. Ngati kufunika n'lakuti, dongosolo wachifundo kumawonjezera Tikaganizira za mphamvu, kotero thupi choti apitirize kugwira ncthito zambiri ndi kugwira ntchito yake. Pamene tikukamba za mwayi zobisika ndi chuma, tikutanthauza ndendende. Pa momwe dongosolo adzakonza izo, kudzadalira chikhalidwe cha thupi.

Komabe, zonsezi ndi nkhawa amphamvu thupi, kotero yaitali mode izi, izo sizingakhoze kugwira ncthito. Apa pakubwera mu dongosolo parasympathetic, amene ali ndi ntchito ndalama komanso kubwezeretsa kudzikundikira awo, moti kenako munthu anali wokhoza kuchita ntchito yomweyo, koma mbali wake sukhala. Chifundo ndi parasympathetic mantha dongosolo kulola kugwira ntchito zachilendo m'thupi la munthu mu zikhalidwe zosiyanasiyana. Amagwira ntchito inseparably ndi mosalekeza azigwirizana.

Monga tanena kale, kachitidwe wachifundo ndi adamulowetsa mokwanira mavuto. Mu ena amanena umatchedwa zotakasika wachifundo mantha dongosolo, chifukwa apereke Poyankha ena thupi zinthu, anapanga kuchokera kunja.

Pa nthawi imeneyi ku England adrenal amayamba kutulutsa zikuwonjezereka masiku ano, zomwe ndi thunthu waukulu amalola anthu abwino ndipo angachite mavuto mofulumira. Komabe, zochitika zofanana kumachitika pamene thupi, pamene chifukwa amasulidwe zikuwonjezereka masiku ano munthu umayamba kulimbana ndi bwino. zikuwonjezereka masiku ano katulutsidwe timapitiriza kanthu a dongosolo chifundo, limene limayamba ndi "kupereka" chuma kudya kuchuluka mphamvu chifukwa yekha zikuwonjezereka masiku ano kumapangitsa ziwalo zosiyanasiyana ndi mphamvu, koma makamaka eni zipangizo za.

Mmene thupi ndi mkulu mokwanira, chifukwa ndiye munthu akukumana kutopa, kufooka, ndi zina zotero, malingana yaitali bwanji zikuwonjezereka masiku ano tingati ndi utali dongosolo wachifundo amaika zinthu kuthandiza ntchito za thupi pa mlingo chomwecho.
