Reticular mapangidwe. Ubale ndi zochita za galimoto

Brainstem reticular mapangidwe ndi mapangidwe plexiform, kuchuluka kwa nyumba ubongo ili mbali chapakati (thalami, midbrain ndi medulla). Manyuroni kuti kupanga izo, zimasiyana mu kukula, neurite m'litali, dongosolo. Chikondwerero yokhotakhota awo wandiweyani.

Nchito ya mapangidwe reticular

Mapangidwe ndi wachibale cerebellum ndi, msana, kotekisi mu hemispheres oziziritsa, ndi limbic (kupereka zosiyanasiyana zofunika kwambiri m'thupi) dongosolo. Mu mapangidwe thumba kucheza akukwera (afferent) ndi kutsikira (efferent) nyemba. The nyemba akhoza zimafala ndi kutsekedwa madera ubongo. Pankhaniyi, mukubwadamuka zonse amaperekedwa mu reticular manyuroni lomenyera ena mlingo. Chifukwa ndi kudzipereka ena kuti ntchito za m'madipatimenti osiyanasiyana a chapakati mantha dongosolo. Kusintha mlingo wa malemeredwe la mapangidwe mauna ikuchitika makungwa hemispheres.

Reticular mapangidwe limapangidwa zigawo ankatha kupereka kapena zomwe zotsatira ochepetsera pa zochita msana galimoto.

Kwa nthawi yoyamba ubale pakati pa bongo msana ndi kukondoweza mwa madera osiyanasiyana mapangidwe mauna anapeza I. M. Sechenovym. Zotsatira za American neurophysiologist Megounom ndi thandizo la ogwira ntchito bwino Chitsanzo cha ananena Sechenov.

Choncho, pamene magetsi kukondoweza kwa munda medial ku anyani zamizidwa ndi kusakhala ndi amphaka pali kutha wathunthu kuyenda, monga reflex, ndipo amachititsa kukondoweza kwa mabacteria mota wa kotekisi ubongo. Motero chodabwitsa nagawa kuti amakwiya mapangidwe reticular, kakusintha kuyabwa, ndi amgwirizano m'chilengedwe.

Atadziŵa kwa lateral reticular zone lomenyera periphery, ndipo tiyesetsa kuti ochepetsera zotsatira dera wapezeka mutsogolo zotsatira ntchito msana galimoto.

Mapangidwe reticular pantchito pa maphunziro osiyana msana.

Tikumbukenso kuti dera la mapangidwe mauna, okhala mutsogolo zotsatira ntchito galimoto chimafikira anteriorly. Choncho chimakwirira osati m'dera la medulla oblongata, koma ndi midbrain ndi pons.

maphunziro Net zingakhudze minofu kamvekedwe. Izi lotseguka malo R. lubwe. Swedish neurophysiologist anasonyeza kuti mapangidwe reticular zimakhudza ntchito manyuroni Popanga madzi a gamma galimoto. axons awo kudutsa otchedwa "intrafuzarnym" ulusi minofu ndi kusankha yofunika kwambiri mu lamulo la gawo kayendedwe ka thupi ndi njira zosiyanasiyana.

malo osiyanasiyana mapangidwe reticular zimakhudza zolimbikitsa chikhalidwe zowombetsa mkota wa kotekisi oziziritsa, kuchita ndi malo ake.

Kukhalabe mauna mapangidwe ntchito ndi kudziwa zinthu zosiyanasiyana mankhwala kufalitsidwa magazi ikuchitika ndi zinthu humoral (carbon dioxide, makatekolamaini, etc ..). Zimenezi, kumathandiza kuti kusakanikirana kwa reticular lomenyera lamulo la ntchito zina autonomic.

Tikumbukenso kuti kuphunzira za unansi wa mapangidwe mauna ndi nyumba zina subcortical, izo anatilola kuti sule katundu wa asilikali neurophysiological wa chikhalidwe cha limati munthu (ululu, m'maŵa, tulo, maso, maganizo ndi angalimbikitsire limati ndi ena). Ntchito maphunziro Medicine limasonyeza njira payekha CNS pathologies umakhala njira zatsopano mavuto ena zachipatala.
