Tangata analyzer vestibular. Hanganga me te mahi

Ko te analyzer vestibular ko te pūnaha o ngā hanganga neural me mechanoreceptors, e taea ai te tangata ki te kite me te arata'i ai tika te tūranga o tona tinana i roto i te wāhi. Mechanoreceptors whakaohooho he ahua rerekē o te whakatere. meinga pokatata koki excitation receptors ampullar. whakatairanga te āhua tapa torotika pūoko whakaterenga tupu pini i roto i te whakamahau. E tahuri Vestibular me ngātere ampullar ki tohu io me te āwhina kia mau i te pūnaha io pokapū, te takotoranga i roto i te wāhi.

Ko te hanganga o te analyzer vestibular tangata

E mohio reflexes pateko i roto i te taunekeneke o tinana ahei ki te kite whakaohooho, me te whakaahua ke ratou ki ponana io. Signals e haere mai ana i te taputapu vestibular ki te karere vestibular, i roto i nei tomo ratou i nga rohe o te oblongata medulla. I runga i te mahana o toku aroha, a whakanohoia he putea. ratou mata hipoki pūtau rongo nei e wehea ki puka hanga tīwae me te pea. E karapotia e te membrane otolith makawe tairongo o enei pūtau. A, no te nuku te kaupapa o te matenga i te kaha o te mahara o te otoliths me pā te makawe tairongo. Ki te wahi basal o te pūoko pūtau hopearaa hono-karere e riro tohu i te makawe.

mahi taketake

He ako o te analyzer vestibular whakakitea e rima ngā momo o ngā tauhohe e kua whakaputaina e ratou:

1. meinga Vestibulosomaticheskie tauhohe vestibulo here. Ki te to ratou awhina, whakatairanga analyzer vestibular Tuhinga o āhua uaua i ngā pokatata rerekē.
2. tauhohenga Oculomotor. E meinga ratou e te aroaro o hononga kanohi-nekeneke me meinga nekehanga tumu o te kanohi nystagmus ranei. Ko te biphasic tenei tukanga. I roto i te wāhanga tuatahi te ritenga receptor ampullar me kaupapa puhoi muri ki te kanohi. I roto i te wāhanga tuarua hua i roto i te nekehanga kapeneheihanatia nenewha tere hoki ki te tūranga taketake. analyzer Vestibular whakaoho nystagmus mō te whakatika whatiwhatinga taiao whakapau i roto i te kaupapa takahuri. Reira tauturu hoki he tauhi ara tangata o ngā e kei neke i te tere tiketike.
3. He urutau mahi Vestibular pūāhua. Ki te whai koe i tetahi o enei tauhohe ai palpitations, pēhanga toto nui haere, meinga whakapairuaki i runga i te whakamārama o te tere mahi.
4. Vestibulomozzhechkovye tauhohe puta i roto i te kaupapa hohe. whai wāhi ratou ki te mana o te tūranga tinana i roto i te wāhi, ina ko te tinana i roto i te āhua hihiri. rite tenei e tohatoha tika o te āhua uaua i ngā pokatata rerekē.
5. Ngā mihi ki te hononga ki te analyzer uho vestibular tauturu te whakatinanatanga o te aroturuki me te ako vestibulosensornoy tauhohenga pokapū.
