Kanaka vestibular mea kālailai. 'Ole a me ka ho'āʻo

Ke vestibular mea kālailai o ka'ōnaehana o neural hale a me mechanoreceptors, e leie aku kekahi kanaka i ka ike a me ka pono orient i ke kulana o kona kino i loko o ka lewa. Mechanoreceptors stimuliʻokoʻa ano o ka hoʻonui. Angular accelerations i excitation ampullar receptors. Ke rectilinearʻano paipai 'ia ka hoʻonui nā mea e loaʻa ka mea nalo lāʻau ikiʻai wale hanana ma ka lanai. Vestibular a ampullar lāʻau ikiʻai wale i hoohuliia mai i loko o nā aʻalolo lepa, a kōkua malama i ka Central ko mākou hopohopo'ōnaehana, i ke kohoʻia i loko o ka lewa.

A like o ka vestibular mea kālailai hoike elimaʻano o nā reactions a lakou i hua mai la:

1. Vestibulosomaticheskie reactions kena ae la vestibulo paa. Me kā lākou kōkua, vestibular mea kālailai paipai 'ia ka redistribution o Muscle leo ma kekahi mau accelerations.
2. Oculomotor naoh. Ka mea, i ke kumu ma ke alo o ka maka-Hawaii i pili ai, a i involuntary ka neʻe 'ana o na maka a me nystagmus. Kēia kaʻina He biphasic. Ma ka mea mua pae ka ae hookaawale ampullar mea loaʻa, a mahope lohi ana i ka maka. Ma ka lua o ka pae kūpono ma kokololio ka noi compensating'ōnohi a hoi hou i ka palapala wahi. Vestibular mea kālailai hoʻonāukiukiʻana mai o nystagmus no ka hoʻopunipuni a no ka maluhiluhi papa hakina i ka rotational neʻeʻana. Ua i kōkua i kekahi kanaka e malama i Track o ka mea e e neʻe ana kiʻekiʻe māmā.
3. Vestibular hana i adaptable külana. Inā 'oe i kekahi o kēia mau reactions i palpitations, mahuahua ke koko, i nausea ma luna o ke kāʻei kua o accelerating hana.
4. Vestibulomozzhechkovye reactions hana ana iʻeleu neʻeʻana. Ka mea, he hoʻonui i ka hooponopono ana o ke kino i nā hana i loko o ka lewa, i ka wa a ke kino i loko o ka hōʻeuʻeu moku'āina. Kēia Ua hooko ia e pono hoi o ka makana o ke Muscle leo ma kekahi mau accelerations.
5. Mahalo i ka pili 'o Randy me ka vestibular cortex mea kālailai kōkua i ka hoʻokō' ana o ke kikowaena ka mālamaʻana a me ka hooponopono hou vestibulosensornoy naoh.
