Wosanthula munthu wamatsenga. Chikhalidwe ndi ntchito

The vestibular analyzer ndi dongosolo la mitsempha ndi ma mechanoreceptors omwe amalola munthu kuzindikira ndi kulongosola molondola malo ake a mlengalenga. Zokakamiza za mechanoreceptors ndi mitundu yosiyanasiyana ya kuthamanga. Kuthamanga kwazing'ono kumayambitsa chisangalalo cha opullar receptors. Chikhalidwe chokhazikika cha kuthamanga kumathandizira kuoneka kwa zofuna m'magulu a nyumbayo. Zomwe zimagwiritsidwa ntchito pazithunzithunzi ndi zamagetsi zimasandulika kukhala zizindikiro za neural ndikuthandizira dongosolo la mitsempha lopitirira kukhala loyendetsa mu danga.

Mapangidwe a analyzer ya anthu

Maganizo oyenera amadziwika chifukwa cha kugwirizana kwa ziwalo zomwe zimatha kuzindikira zomwe zimawathandiza ndikuzisintha . Zizindikiro zimabwera kuchokera kumagetsi ovala zovala mpaka ku mitsempha yambiri, yomwe imalowa m'madera a medulla oblongata. Kuthamanga kuli martha ndi thumba. Awo Pamwamba pamakhala ndi maselo ofunika, omwe ali ndi mawonekedwe omwe amagawidwa m'mizere ndi mapeyala. Mutu wochuluka wa maselowa uli kuzungulira ndi membrane yotchedwa otolith. Mutu ukamayenda chifukwa cha mphamvu yokoka, otoliths imasunthira komanso imachita tsitsi. Mapeto a mitsempha akugwirizanitsidwa ndi gawo loyambira la maselo a maselo, omwe amadziwa chizindikiro kuchokera kumutu.

Ntchito zazikulu

Kuphunzira kwa vestibular analyzer kunawonekera mitundu isanu ya momwe amachitira:

1. Zochita za Vestibulosomatic chifukwa cha vestibulospinal ligaments. Ndi chithandizo chawo chojambulira chojambulira chimalimbikitsa kugawidwa kwa minofu pamtundu wofulumira mosiyanasiyana.
2. Zotsatira za oculomotor. Zimayambitsidwa ndi kukhalapo kwa magalimoto oyang'ana maso ndipo zimayambitsa kayendedwe ka maso kosasamala kapena nystagmus. Izi zimakhala ndi magawo awiri. Gawo loyambirira, kukondweretsa kwa ampullar receptor kumachitika ndipo kuyenda kofulumira kwa maso kumbali. Pachigawo chachiwiri, chifukwa cha kayendetsedwe kowonjezera msanga, maso a maso amabwerera ku malo awo oyambirira. The analyzer vestibular analyzer amachititsa nystagmus kukonza zidutswa zam'mlengalenga panthawi yoyendayenda. Zimathandizanso munthu kusunga zinthu zomwe zimayenda mofulumira.
3. Vestibulovegetative ntchito ndi adaptive Makhalidwe. Pamene zotsatirazi zimachitika, pangakhale kuwonjezeka kwa mtima wa mtima, kuwonjezeka kwa kuthamanga kwa magazi, kuwonekera kwa mseru pamsana pa msangamsanga.
4. Zochitika za Vestibulomozzhechnye zikuwonetsedwa panthawi yogwira ntchito. Amathandizira kulamulira thupi la mlengalenga, pamene thupi liri ndi mphamvu. Izi ndi chifukwa cha kufotokoza kolondola kwa minofu ya minofu mofulumira mosiyana.
5. Chifukwa cha kukhalapo kwa chidziwitso cha cerebral cortex, chojambula chojambulira chimathandizira kupanga pakati ndi kuwongolera kwa vestibulosensory reaction.
