Analyzer vestibular Human. Qaab-dhismeedka iyo shaqada

analyzer The vestibular waa nidaam ka mid ah dhismayaasha neural iyo mechanoreceptors, kaas oo u ogolaanaya qofka loo garto iyo sida saxda ah cabbiri meel jidhkiisa ah in meel bannaan oo. Mechanoreceptors ku meersan yihiin nooc kala duwan ee xawaaraha. accelerations angular keeni excitation receptors ampullar. Dabeecadda rectilinear kor u dareemayaal dardargelinta dhacdo garaaca wadnaha ee balbalada. Vestibular iyo digir ampullar waxaa beddelay calaamadaha dareemayaasha iyo caawiyaan nidaamka dhexe ee habdhiska, hanuuninta ee bannaan.

Dhismaha analyzer ku vestibular aadanaha

hummaag guurto ah waxaa lagu ogaaday iyada oo xidhiidhka ka mid ah jirkooda oo awood u leh inay Arkaa ku meersan iyo iyaga u beddesho galay falalkooda dareemayaasha. Signalada ka imanaya hay'adaha vestibular in dareemaha vestibular, kaas oo ay soo galaan gobollada ee oblongata medulla ah. Habeeynimadii of my curiso iyo kaalinta bac. ay dusha daboolay unugyada dareenka oo kala qaybsan yihiin foomka columnar iyo pear. timaha xasaasi ah unugyadan ku hareereysan xuub otolith. Marka dhaqdhaqaaqa madaxa ciidamada of cuf ee otoliths ka baddalo iyo saamayn timaha dareenka. Si aad qayb ka mid ah asalka ah ee gacanta shidma dhammaato xiran-dareemaha in ay helaan signalada ka timaha.

hawlaha aasaasiga ah

Daraasad ee analyzer ku vestibular shaaca ka qaaday shan nooc oo dareen diidmo oo ay soo saartay:

1. reactions Vestibulosomaticheskie sababay vestibulo bonds. Iyadoo ay gargaar, analyzer vestibular kor u qaybin cabirida xaalada muruqa at accelerations kala duwan.
2. reaction Oculomotor. Waxaa sababa jiritaanka xiriir il-motor oo keeni dhaqdhaqaaq aan ikhtiyaarka lahayn indhaha ama nystagmus. Tani waxa biphasic. In wajiga koowaad cuncun receptor ka ampullar iyo dhaqdhaqaaqa gaabis ah ku xiga dhinaca isha. In wajiga labaad taasoo keentay in mooshin celino jallo deg deg ah ku soo laabto booska asalka ah. analyzer Vestibular dhirfinaya nystagmus for qamaar jajabkii deegaanka dhammayn inta lagu guda jiro dhaqdhaqaaqa wareeg ah. Waxay kaloo ka caawisaa qofka track sii of a walxaha u guurayso ee xawaaraha sare.
3. hawlaha Vestibular waa la qabsan kara qof. Haddii aad qabto wax celintan oo laga yaabaa in wadno, kordhay cadaadiska dhiigga, waxay keeni lallabo ku saabsan asalka ah ee dardar-tallaabo.
4. reactions Vestibulomozzhechkovye dhacaan inta lagu jiro dhaqdhaqaaq firfircoon. Waxay ka qayb qaataan gacanta ugu booska jidhkaaga in meel, marka jidhku waa xaalad firfircoon. Tani waa mid ku fula qaybinta habboon ee cabirida xaalada muruqa at accelerations kala duwan.
5. Thanks to xiriir la analyzer ah kiliyaha vestibular caawisaa fulinta kormeerka iyo la saxo falcelinta vestibulosensornoy dhexe.
