ʻO ia ka mea e hiki ai iā ʻoe ke lohe a mālama i kou kaulike: ʻO ke aʻalolo Vestibulocochlear ma nā huaʻōlelo maʻalahi!

I kēia lā, e kamaʻilio ana mākou e pili ana i kahi ʻāpana kupaianaha a koʻikoʻi loa o ko mākou kino. Ua noʻonoʻo paha ʻoe pehea ʻoe e lohe ai i ke kani, a pehea ʻoe e mālama ai i kou kaulike a kū pololei me ka ʻole o ka hāʻule ʻana? Aia kekahi mea e kōkua ana i kēia mau mea a pau, ʻo ia ka mea nāna e lawe i nā leka mai loko mai o ko mākou pepeiao a i ka lolo. Ua kapa ʻia kēia ʻo ke aʻalolo vestibulocochlear . ʻOiai paha he lōʻihi iki ka inoa, he nui loa ka hana āna e hana ai. E aʻo hou kākou e pili ana i ia mea ma ke ʻano maʻalahi.

He aha kēia aʻalolo vestibulocochlear?

I ka ʻōlelo maʻalahi, ʻo kou aʻalolo vestibulocochlear kahi ʻano i hana ʻia me ʻelua ʻāpana. ʻO kāna hana nui ka lawe ʻana i ka ʻike sensory mai kou pepeiao i loko a i kou lolo. Ua like nā aʻalolo me nā kaula liʻiliʻi i loko o ko mākou mau home. Lawe kēia mau kaula i ka ʻike, e like me nā leka uila, mai kēlā me kēia o nā manaʻo o ko mākou kino a i ka lolo. A laila hiki i ka lolo ke hoʻohana i kēlā ʻike e hoʻonohonoho pono i nā hana o ko mākou kino.

ʻO ke aʻalolo vestibulocochlear ka mea nui e lawe i ka ʻike mai nā ʻāpana ʻelua i loko o kou pepeiao i loko. ʻO kekahi ka ʻāpana e kōkua iā ʻoe e lohe i nā leo , a ʻo kekahi ka ʻāpana e kōkua iā ʻoe e mālama i ka "manaʻo kaulike" o kou kino.

ʻO ke aʻalolo vestibulocochlear kekahi o nā aʻalolo cranial he ʻumikūmālua i loko o ko kākou poʻo. Kōkua kēia mau aʻalolo cranial iā kākou e honi, ʻono, hoʻopā, a hana i nā ʻano helehelena. ʻO ke aʻalolo vestibulocochlear ka walu o kēia mau aʻalolo cranial he ʻumikūmālua (cranial nerve VIII a i ʻole CN VIII) . Pili nui ia i ka lohe a me ke kaulike. I kekahi manawa ua kapa ʻia ʻo ia ʻo ke aʻalolo vestibular auditory.

No laila he aha ka hana nui o kēia aʻalolo?

ʻO ka inoa "vestibulocochlear" ponoʻī e hāʻawi i kahi hōʻailona i nā ʻāpana ʻelua o kēia aʻalolo a me kā lākou mau hana. He mea maʻalahi loa ia, e nānā wale:

• ʻO ke aʻalolo Vestibular: ʻO kēia ka ʻāpana "vestibulo" o ka inoa. Lawe ia i ka ʻike mai nā ʻōpū o kāu ʻōnaehana vestibular i kou lolo. ʻO kēia mau ʻōpū vestibular ka mea e ʻike i ka ʻike e pili ana i ke kūlana o kou poʻo a me nā neʻe ʻana o kou poʻo. Hoʻohana kou lolo i kēia ʻike e kōkua iā ʻoe e mālama i kou kaulike. E noʻonoʻo, kōkua kēia ʻōnaehana iā ʻoe mai ka hāʻule ʻana i kou hele ʻana, holo ʻana, a lulu paha i kou poʻo.

• ʻO ke aʻalolo cochlear: ʻO kēia ka ʻāpana "cochlear" o ka inoa. Lawe ia i ka ʻike kani mai kou cochlea , kahi ʻāpana ʻano nahe o kou pepeiao i loko, i kou lolo. Hoʻohana kou lolo i kēia ʻike e kōkua iā ʻoe e ʻike a lohe i nā leo.

Hoʻohui pū kēia mau aʻalolo ʻelua e hana i ke aʻalolo hoʻokahi i kapa ʻia ʻo `CN VIII`. Eia nō naʻe, ma hope o ka hui ʻana, hana kēlā me kēia i kāna hana ponoʻī - ʻo ia hoʻi, ka lawe ʻana i nā leka e pili ana i ke kaulike a me ka lawe ʻana i nā leka e pili ana i ka lohe.

Hiki iā ʻoe ke wehewehe iki e pili ana i ka hana ʻana o ke aʻalolo vestibular?

Lawe kou aʻalolo vestibular i ka ʻike mai nā ʻōkana o ka ʻōnaehana vestibular i kou lolo . ʻO kou mau ʻōkana vestibular he ʻelua mau ʻōkana otolith (i kapa ʻia hoʻi he utricles a me saccules) a me ʻekolu mau kahawai semicircular. Ua piha kēia mau ʻōkana ʻelima i ka wai a loaʻa iā lākou nā pūnaewele sensory. Ke neʻe ʻoe i kou poʻo, neʻe kēia wai a me nā ʻōkana.

Eia ke ʻano o ka hana ʻana o ke aʻalolo vestibular:

1. Hoʻomaka ka hōʻailona: Ke hoʻoneʻe ʻoe i kou poʻo, neʻe ke kahe i loko o nā ʻōkana vestibular. A laila neʻe nā hunaola sensory i loko o lākou. Hoʻokumu kēia neʻe ʻana i kahi hōʻailona e pili ana i ke kūlana a me ka neʻe ʻana o kou kino.

2. Hāpai nā ʻiwi aʻalolo (neurons) i ka hōʻailona: Hāpai kēia mau ʻiwi aʻalolo i ka hōʻailona ma ke aʻalolo vestibular. Hele kēia leka i kahi i kapa ʻia ʻo ka vestibular nuclei complex ma ke kumu o ka lolo. He ʻehā mau nuclei o kēia complex. Hoʻouna kēlā me kēia o kēia mau nuclei i loko o ka lolo i nā hōʻailona i nā ʻāpana like ʻole o ke kino, i hiki iā ʻoe ke mālama i ke kaulike.

3. Hana ka lolo i ka ʻike kaulike: Hoʻouna kekahi mau nuclei i nā hōʻailona sensory e pili ana i ke kūlana o ke kino i nā ʻāpana o ka lolo e like me ka cerebral cortex a me ka cerebellum. Hoʻouna kekahi mau nuclei i nā hōʻailona sensory i kou ʻāʻī a me nā wāwae, e kōkua ana iā ʻoe e hoʻoponopono i kou kūlana. Hoʻouna kekahi mau nuclei i nā hōʻailona sensory i nā ʻiʻo i loko o kou mau maka, e kōkua ana i kou mau maka e noho kālele ma kahi hoʻokahi ʻoiai ke neʻe nei kou kino. Ua kapa ʻia kēia ʻo ka vestibulo-ocular reflex (VOR) . E noʻonoʻo, i kou holo ʻana i kahi kaʻa, ma muli o kēia VOR hiki iā ʻoe ke nānā i kahi hōʻailona ma waho.

I kēia manawa, e nānā kākou pehea e hana ai ke aʻalolo cochlear (ke aʻalolo lohe).

ʻO kou aʻalolo cochlear (i kapa ʻia hoʻi ʻo ke aʻalolo auditory) e lawe i ka ʻike mai kou cochlea a i kou lolo. E like me nā ʻōkana o ka ʻōnaehana vestibular, ua piha kou cochlea i ka wai a loaʻa iā ia nā hunaola lauoho sensory. Ke hiki mai nā nalu kani, e haʻalulu kēia mau wai a me nā hunaola.

Eia ke ʻano o ka hana ʻana o ke aʻalolo cochlear:

1. Hoʻomaka ka hōʻailona: Ke hiki aku nā nalu kani i kou cochlea, ʻo ka membrane basilar i lokoHoʻoluliluli kahi membrane i kapa ʻia ʻo ka eardrum. Hoʻoulu kēia haʻalulu i nā hunaola lauoho koʻikoʻi ma ka membrane e neʻe. Ke neʻe nā hunaola, hoʻopuka ʻia kahi hōʻailona e pili ana i ke ʻano o ke kani. Hoʻokomo pū kēia i nā mea e like me ke alapine (pinepine) o nā nalu kani (ʻo ia hoʻi, pehea ke kiʻekiʻe a i ʻole ka haʻahaʻa o ke kani - 'pitch') a me ka nui o ke kani.

2. Lawe ʻia ka hōʻailona e nā ʻaʻalolo: Lawe nā 'Neurons' (nā ʻaʻalolo) i kēia hōʻailona ma ke aʻalolo lohe, a hiki i kahi i kapa ʻia ʻo 'cochlear nuclei' i loko o ke kumu o ka lolo. ʻEkolu mau ʻāpana o kēia mau cochlear nuclei. Loaʻa i kēlā me kēia ʻāpana nā ʻano ʻike like ʻole e pili ana i ke kani. No ka laʻana, loaʻa i kekahi mau ʻāpana ka ʻike e pili ana i nā leo me nā alapine haʻahaʻa, e like me nā leo bass. Loaʻa i nā ʻāpana ʻē aʻe ka ʻike e pili ana i nā leo me nā alapine kiʻekiʻe, e like me nā leo kiʻekiʻe.

3. Hoʻoponopono ka lolo i ka ʻike kani: Hoʻouna nā nuclei cochlear i nā hōʻailona sensory e pili ana i ke kani i ka auditory cortex o kou lolo. Aia kēia ma ka temporal lobe o ka lolo. ʻO kēia kahi e hana ʻia ai a hoʻomaopopo ʻia ai ka ʻike kani āu e lohe ai.

ʻAʻole anei he mea kupaianaha? Nui nā mea e hiki ke hana me kēia aʻalolo liʻiliʻi! Ua like ia me kahi ʻenehana super i loko o ko mākou kino.

No laila ma hea kahi o kēia aʻalolo vestibulocochlear?

Aia ke aʻalolo vestibulocochlear ma kahi alahele iwi i kapa ʻia ʻo Internal Auditory Canal (IAC) , kahi e pili ai kou pepeiao i loko i ka ʻaoʻao lalo o kou iwi poʻo.

• Hoʻomaka ke aʻalolo vestibular i loko o kahi puʻupuʻu o nā aʻalolo i kapa ʻia ʻo ka ganglion vestibular (`Vestibular (Scarpa's) ganglion`) kokoke i nā ʻōpū vestibular. Hoʻohui ia i ke aʻalolo cochlear i loko o ka `IAC` e hana i ka `CN VIII`. Eia naʻe, hoʻokaʻawale hou ia mai ke aʻalolo cochlear ke hiki aku i ka vestibular nuclei complex ma ka brainstem.
• Hoʻomaka ke aʻalolo cochlear i loko o kahi puʻupuʻu o nā aʻalolo i kapa ʻia ʻo ka spiral ganglion kokoke i ka cochlea. Hoʻohui kēia i ke aʻalolo vestibular i loko o ka IAC e hana i ka CN VIII. A laila hoʻokaʻawale ia mai ke aʻalolo vestibular ke hiki aku i kona mau nuclei like i loko o ka lolo.

I ka ʻōlelo maʻalahi, me he mea lā e hoʻomaka ana kēia mau aʻalolo ʻelua ma ka pepeiao o loko, e hele pū ana no kahi mamao pōkole, a laila e hoʻokaʻawale hou e hana i kā lākou hana ponoʻī ke komo lākou i loko o ka lolo.

He aha ka mea i hana ʻia ai ke aʻalolo vestibulocochlear?

ʻO ke aʻalolo vestibulocochlear ua hana ʻia me nā neurons sensory (afferent neurons) . ʻO ke ʻano kēia, ʻo kāna kumu wale nō ka lawe ʻana i nā hōʻailona e kōkua i ka lolo e hana i ka ʻike e pili ana i kou mau manaʻo (e like me ka lohe a me ke kūlana o ke kino). ʻAʻole ia e lawe i nā leka motor, ʻo ia hoʻi, nā leka mai ka lolo a i nā ʻiʻo.

He aha nā kūlana maʻamau e hiki ke hoʻopilikia i ke aʻalolo vestibulocochlear?

ʻO ka mea pōʻino, aia kekahi mau kūlana e hiki ke hōʻino i kēia aʻalolo koʻikoʻi. ʻO kekahi o lākou:

• Nā ʻeha: Nā ʻeha i nā ʻāpana o kou iwi poʻo, ʻoiai ma kahi o kou pepeiao i loko. E noʻonoʻo e like me ke kuʻi ʻana i kou poʻo.
• Nā kūlana hānau (nā pilikia i loaʻa i ka wā hānau): I kekahi manawa, hiki ke loaʻa nā pilikia mai ka hānau ʻana mai no ka mea ʻaʻole i ulu pono ka CN VIII.
• Nā puʻupuʻu: Hiki ke loaʻa nā puʻupuʻu ʻaʻole maʻi kanesa (benign), e like me nā neuromas acoustic . ʻOiai ʻaʻole kēia he maʻi kanesa, hiki iā lākou ke hana i nā pilikia ma ke kaomi ʻana i ke aʻalolo.
• Nā maʻi: ʻO nā maʻi e like me ka vestibular neuritis a i ʻole labyrinthitis hiki ke hōʻino i kēia aʻalolo.

Pehea e ʻike ai inā he pilikia koʻu me koʻu aʻalolo vestibulocochlear? (Nā hōʻailona)

Inā ua hōʻino ʻia kou aʻalolo vestibulocochlear, hiki iā ʻoe ke ʻike i nā hōʻailona e hoʻopilikia i kou lohe a me kou hiki ke mālama i ke kaulike. E nānā e ʻike inā loaʻa iā ʻoe kekahi o kēia mau mea:

• Pohō lohe sensorineural: ʻO kēia ka pohō lohe i hoʻokumu ʻia e kahi pilikia i loko o ka pepeiao o loko.
• Tinnitus: He kani ʻana, he buzzing, a he buzzing paha i loko o nā pepeiao. No kekahi poʻe, kani paha kēia me he leo hū a hū paha.
• Pōniuniu: He manaʻo o ka wili ʻana, ka māmā o ke poʻo, a i ʻole ka nalowale o ke kaulike.
• Vertigo: He manaʻo e wili ana nā mea a puni ʻoe, a i ʻole e wili ana ʻoe, ʻoiai ke kū mālie nei ʻoe. Hiki i kēia ke manaʻo e like me ʻoe e piʻi ana a iho ana ma luna o kahi ʻūlū.
• Nystagmus: Ka neʻe wikiwiki a kaohi ʻole o nā maka.

Inā loaʻa iā ʻoe kekahi a ʻoi aku paha o kēia mau hōʻailona, ​​​​ʻoi aku ka maikaʻi o ka ʻike koke ʻana i ke kauka . He mea nui e ʻimi i ke kumu a hoʻomaka koke i ka lāʻau lapaʻau.

Pehea e nānā ai nā kauka i ke olakino o kēia `CN VIII`?

Aia kekahi mau hoʻokolohua a nā kauka e hoʻohana ai e nānā i ke olakino o kou aʻalolo vestibulocochlear:

• Nā hoʻāʻo lohe: Hana ʻia kēia mau hoʻāʻo e ʻike inā he nalowale ka lohe i loko o kou pepeiao o loko. ʻO nā hiʻohiʻona e komo pū me ka hoʻāʻo Rinne a me ka hoʻāʻo Weber . Ma kēia mau hoʻāʻo, kau ke kauka i kahi ʻō hoʻolohe haʻalulu (kahi ʻano ʻō hoʻolohe) ma kou poʻo a kokoke i kou pepeiao a nānā e ʻike inā hiki iā ʻoe ke lohe i nā leo.
