Human vestibular analyzer. Structure na ọrụ

The vestibular analyzer bụ a usoro nke nural owuwu na mechanoreceptors, nke na-enye ohere a onye na-aghọta na n'ụzọ ziri ezi ifu ọnọdụ nke ya ahu na ohere. Mechanoreceptors stimuli bụ dị iche iche ụdị nke osooso. Angular accelerations ime ka excitation ampullar anabata. The rectilinear uwa akwalite osooso sensọ usu omume na ihe owuwu ụzọ mbata. Vestibular na ampullar pulses na-converted n'ime akwara n'ókè na-enyere na-Central ụjọ usoro, nghazi na ohere.

A na-amụ vestibular analyzer kpughere ise ụdị ndị Jeremaya mere, nke ha na-emepụta:

1. Vestibulosomaticheskie Jeremaya mere vestibulo agbụ. Na enyemaka ha, vestibular analyzer akwalite redistribution nke Akwara ụda dị iche iche accelerations.
2. Oculomotor mmeghachi omume. Ha na-kpatara ọnụnọ nke anya-moto njikọ na-eme ka ịsụ mmegharị nke anya ma ọ bụ nystagmus. Usoro a bụ biphasic. Ke akpa na-adọ ndị iyatesịt ampullar ihe nnabata na ụdi ngwa ngwa ije kwupụta anya. Na nke abụọ na-adọ na-akpata ngwangwa ngagharị compensating eyeballs laghachi n'ọnọdụ mbụ. Vestibular analyzer akpalite nystagmus maka idozi iyuzucha gburugburu ebe obibi iberibe n'oge na rotational ije. Ọ na-enyere onye na-esochi nke ihe na-akpụ akpụ na elu na-agba.
3. Vestibular ọrụ bụ na-eme mgbanwe agwa. Ọ bụrụ na ị nwere ihe ọ bụla nke ndị a Jeremaya mere nwere ike palpitations, mụbara ọbara mgbali, ime ka ọgbụgbọ na a ndabere nke ngwa ngwa eme ihe.
4. Vestibulomozzhechkovye Jeremaya mere eme n'oge ifịk ije. Ha na-eme ka akara nke ahụ itie ke ohere, mgbe ahụ bụ na a na-akpa ike ala. Nke a na-emezu site kwesịrị ekwesị nkesa nke Akwara ụda dị iche iche accelerations.
