Analyzer Human vestibular. Sakhiwo umsebenzi

Le analyzer vestibular yinkqubo kwezakhiwo zemithambo kunye mechanoreceptors, nto leyo evumela umntu wokubona hlengisa ngokufanelekileyo kwisikhundla yomzimba wakhe esithubeni. Mechanoreceptors ezintweni ezi uhlobo olwahlukileyo lunikezelo. accelerations emboxo ukuba excitation nezamkeli ampullar. Uhlobo rectilinear ikhuthaza abenzi lunikezelo ukubetha ukwenzeka kwi kwevaranda. Vestibular kunye pulses ampullar zitshintshele ibe amaza-luvo aze ancede ukugcina inkqubo luvo, lokuQhelaniswa esithubeni.

Ubume analyzer vestibular abantu

ikhaliphe ezimile ifezekiswe nge impefumlelwano imizimba nabakwaziyo wokubona ezintweni uze uguqule zibe azilawule luvo. Amaza evela izixhobo vestibular ukuya luvo vestibular, ukuba ngalo bangene kwimimandla ye Oblongata Medulla. Phambi kokubhiyozela obathanda yam watsho ebhegini. zabo umphezulu igqunyiweyo iiseli bakhubazeke azizahlulo uhlobo columnar kunye emibhaka. kwaneenwele ezibuthathaka ezi seli singqongwe le ndizayo otolith. Xa intshukumo intloko amandla nondiliseko otoliths shift kwaye kuchaphazela iinwele nemizwa. Ukuba inxalenye carcinomas yeseli woluvo kwalapho enxulumene-luvo afumana imiyalezo evela kweenwele.

nemisebenzi esisiseko

Ukufunda analyzer vestibular kutyhilwa iintlobo ezintlanu zinto ezakhiwe:

1. Vestibulosomaticheskie reactions yabangela vestibulo neentambo. Ngoncedo lwabo, analyzer vestibular ikhuthaza nokunikezelwa kwezihlunu kwi accelerations ezahlukeneyo.
2. Oculomotor reaction. Bona zibangelwa phambi kokufakelwa eye-motor kwaye zibangela iintshukumo ngokuzenzekelayo yamehlo okanye nystagmus. Le nkqubo biphasic. Kwisigaba sokuqala le eku- receptor ampullar kunye nentshukumo kade emva malunga iliso. Kwisigaba sesibini okukhokelela motion ukubuyekeza amehlo ngokukhawuleza abuyele kwindawo yokuqala. analyzer Vestibular kudale nystagmus ngenxa ukulungisa imeko zeemoto iziqwenga ngexesha le nentshukumo ejikelezayo. Oku kunceda umntu gcinani ingxelo ngayo izinto ezihamba ngesantya esiphezulu.
3. Imisebenzi Vestibular ukuba bhetyebhetye ubuntu. Ukuba ngaba unayo nayiphi na kwezi khemikhali ukuze iyangongoza, ukwanda koxinzelelo lwegazi, zingakwenza ukuba ube nesicefucefu kwi imvelaphi nokukhawulezisa inyathelo.
4. Vestibulomozzhechkovye reactions zenzeke ngexesha intshukumo esebenzayo. Baya kuba negalelo ulawulo omzimba kwisithuba, xa umzimba sikwimo olutshintshayo. Oku kufezwa ukusasazwa eyiyo kwezihlunu kwi accelerations ezahlukeneyo.
5. Ngenxa unxulumano kunye uthinte analyzer vestibular kunceda ukuphunyezwa central esweni kunye nokulungiswa vestibulosensornoy asabela.
