Lolo cerebellum. 'Ole a me ka hana ana o ka cerebellum

Cerebellum ( "uuku lolo") He 'ole i mea ma ka hope hapa o ka lolo ma ke kumu o ka occipital cortex, a me nā kino lobe. ʻOiai ka cerebellum a me ka hola 10% o ka lolo ka leo, ka mea, na oi aku mamua o 50% o ka huina helu o nā neurons loko ia.

Ua Ua lōʻihi ua manaoio cerebellum kanaka Hawaii 'ole, no ka mea,ʻo ka hoʻopilikia maoli impairments ōhumu, koena o ke kino.

Ka huahelu ma luna hōʻike i ka lolo. Ke cerebellum Ua hōʻikeʻia e ka pua.

Eia mea he uuku lolo ma kea pauku.

Ke cerebellum o ka lolo hanaʻia ka mea kēia i hana '.

Ka malama kaulike, a kulou

Ke cerebellum ka mea nui, e malamaʻi i ke koena ma na kanaka kino. Ua loaaʻikepili mai ka vestibular a me ka proprioceptive receptors, a laila, modulates na kauoha e Hawaii neurons me ina e ao ia ana o ka hoʻololi ma ke kino wahi a excessive haawe ana ma luna o nā nāʻiʻo. People me ka pōʻino, ua make cerebellum hoomanawanui mai koena kāna hana.

ōhumu o ka neʻe 'ana o

Hapanui kino neʻe pili i kekahi mau kekahi mau pūʻulu o nāʻiʻo i launa pū 'pu. cerebellum He kuleana no coordinating na neʻe i loko o mākou kino.

Hawaii na palapala he

Ke cerebellum Ua nui no mākou aʻo. Ua Radio nui i kūlana ma ka ka hoʻololiʻana a me ka hoʻoponopono o Hawaii papahana e e kūlike loa ka neʻe 'ana ma ke kaʻina hana o ka hookolokolo ana a me ka hewa o keia hoopunipuni (no ka laʻana, aʻo nâ' âlapa pôhili me nā pāʻani e noi aku ana o ke kino).

Cognitive keʻano o ka hanaʻana (cognitive)

ʻOiai ka cerebellum ua ka loa noʻonoʻo i ka hua'ōlelo o kona nā haʻawina a hiki i ka noi ana ka manaʻo, ka mea, ua kekahi limahana i loko o kekahi cognitive oihana, e like me 'ōlelo. Mau oihana o ka cerebellum o ka lolo i ole i ua aʻo pono lawa ia ia ke hai mai ia makou aku.

Pela, ke cerebellum ua Hawaiʻi nei manaoia like hapa o ka Hawaii'ōnaehana, akā, kona kuleana pili i 'Aʻole i pau i laila.

Ka 'ole o ka cerebellum

Ua ninoieo o ka papa kuhikuhiE māheleʻelua i pili ma ka ilo (waena ciia). ua piha kēia mau māhele mau me ke keʻokeʻo waiwai, kapa komo iā ia me ka lahilahi ahu iho la ka cortical oho mea (cerebellar cortex). ¶ A i loko o ka keʻokeʻo mea o ke alo o nā huhui waina a lākou uuku o oho mea - i ka Kernel. Ma ka lihi o ka ilo mea he apana - ka cerebellar tonsils. Ua 'oe e komo i loko o ka ōhumu o ka neʻe' ana, ka mea e kokua i ka malama i ke koena. Mākou e kaumaha aku i ka pilina nana ma ka 'ole o ka cerebellum.

Ke cerebellum ua maheleia i na wahi he uuku, kela mea keia mea o ka i i kona inoa iho, akā, i loko o ka pauku, e kūkākūkā wale i ka nui loa.

Ka huahelu depicts ka cerebellum. Mau helu i kapa i ka cerebellar hemisphere, a ma o aku o:

1 - anterior lobe; 2 - ka midbrain; 3 - pons; 4 - Klochkova-nodular kaʻana like 'ana; 5 - posterolateral mau māwae,; 6 - ka posterior lobe.

Oeeo? Hoʻopili like e:

1 - cerebellar vermis; 2 - ka anterior lobe; 3 - Main mau māwae,; 4 - hemisphere; 5 - posterolateral mau māwae,; 6 - Klochkova-nodular kaʻana like 'ana; 7 - ka posterior lobe.

hapa o ka cerebellum

Elua nui mawae e holo mediolaterally, cerebellar cortex ua maheleia i ekolu mahele. Posterolateral māwae hoʻokaʻawale Klotchkov-nodular hapa iki o ka lolo o ke kino, a me ka papa kuhikuhiE mau māwae, i hookaawale cerebral kino i loko o anterior a me ka posterior lobe.

Beriana Cerebellum sagittally i puunaueia i ekolu mau mea - na hemispheres mau hoʻokaʻawaleʻia, a me ka awelika (ilo). Ke ilo He palapala wahi ma waena o nā hemispheres elua (maopopo morphological palena ma waena o ka palapala aina, aʻaʻohe kīloi paʻewa hemispheres, cerebellum amygdala mea ma waena o ka ilo, a me nā hemispheres).

cerebellar nuclei

All ÷ ailona lolo cerebellum? Aaeaao me ke kōkua o ka hohonu cerebellar nuclei. Penei, pōʻino i ka cerebellar nuclei i ka ia ia e like me ka huina o na poino i loko o nā mea a pau o ka cerebellum. He nui na ano o ka Kora naʻEsau.

1. Nā nuclei o ka halelewa - ka loa medially aia nucleus o ka cerebellum. Ka mea, loaa lepa mai afferents (nā aʻalolo impulses) o ka cerebellum, vestibular lawe, somatosensory, auditory, a me ka pilikia makapō ike. IIeEeAIEUIeXAIIUEʻano nui i loko o ka keʻokeʻo mea o ka ilo.
2. Next nānaina cerebellar nuclei nā pono mauʻano o ka Korata: - spherical a me ka probkovidnye. Ka mea, i loaa mau lepa a mai ka palapala? Aie? (Ilo) a me ka cerebellum afferents e lawe hoʻi, somatosensory, auditory, a me ka pilikia makapō ike.
3. Dentate nucleus i ka mea nui i loko o ka cerebellum, a e hooponopono ma kaʻaoʻao o keʻano mua. Ka mea, loaa lepa, mai kaʻaoʻao hemispheres a me ka cerebellum afferents i lawe 'ike mai ka cerebral cortex (ka lolo nuclei Via alahaka).
4. Vestibular nuclei ma kēlāʻaoʻao o ka cerebellum, i loko o ka medulla oblongata. ka mea, i ole ia mea, pololei nuclei o ka cerebellum, akā, ua manaoia e e functionally like i kēia mau nuclei, no ka mea, o ko lakou mau hale, ua'ālike. Vestibular nuclei loaa lepa mai nodular Klotchkov-hapa, a mai ka vestibular Kimi.

Ma waho aʻeo ia mau lepa, na Kora naʻEsau, a pau na wahi a pau o ka cerebellum loaa i na mea o ka na momentum o ka emi oliva o ka medulla oblongata.

E koho i ua anatomic wahi cerebellar nuclei hoʻopili like i ka wahi o ka cortex, mai a hookipa mai lakou ia mau lepa a. Penei, ka waena kāna mau 'ōlelo hoolilo Shart lāʻau ikiʻai wale i loaa mai i ka ilo aia ma ka waena; probkovidnyeʻaoʻao a me ka spherical nuclei loaa ia 'ike, mai kaʻaoʻao o ka palapala ciia (i ka ia ilo); a me ka hapanui kāna mau 'ōlelo o kaʻaoʻao kapa loaa mau lepa a mai kekahi a me ka' ē aʻe hemisphere o ka cerebellum.

Nā wāwae o ka cerebellum

Information i na nuclei a me nuclei o ka cerebellum ua pū i hiki ma nā wāwae. Aia he mau ke ano o ka aoao - afferent a me ka efferent (e hele ana i ka cerebellum a me ka mai, niioaaonoaaiii).

1. Lower cerebellar wāwae (i kapaʻia kaula kino) maupaʻaʻano nui ka afferent olona, mai ka medulla oblongata, a me efferents vestibular nuclei.
2. Ka cerebellar wāwae (ole poʻohiwi alahaka)ʻano nui maupaʻa afferents mai na nuclei o na pons.
3. Mawaho cerebellar wawae (a me ka huina poʻohiwi) kuhikuhi maupaʻa efferent olona, mai ka cerebellar nuclei a me kekahi afferent olona, mai spinocerebellar'āpana.

Ke'ī mai, i ka 'ike i loko o ka cerebellum ho'īliʻano nui ma ka lalo a me ka waena cerebellar peduncle, a me ka cerebellum o ho'īli kuhikuhi ma ka mauka wāwae cerebellar.

Aia i hōʻike 'ia i loko o nui au mamuli hapa o ka cerebellum. Ke Kii ka hopuʻiaʻo ia i ka 'ole o ka lolo, nui kaʻoi loa, me ka' ole o ka midbrain. Numbers:

1 - halelewa nucleus; 2 - a probkovidnye spherical kāna mau 'ōlelo; 3 - dentate nucleus; 4 - grubokie cerebellar nuclei; 5 - kaʻoi aʻe colliculus o midbrain; 6 - haʻahaʻa bigeminum; 7 - ka luna holo lolo; 8 - ka luna wāwae cerebellar; 9 - waena cerebellar peduncle; 10 - emi iki mahope o cerebellar wāwae; 11 - tubercle lahilahi kāna mau 'ōlelo; 12 - ke'ākeʻakeʻa mai; 13 - lalo o ka ha o ventricle.

Cerebellar ooieoeiiaeuiuo naehana

Anatomical naehana i ho'ākāka 'ia ma luna, hoʻopili like me ka nui ooieoeiiaeuiiai huahelu ekolu o ka cerebellum.

Arhitserebellum (vestibulotserebellum). Keia hapa nā Klochkova-nodular kaʻana like 'ana a me kona pili ana me ke kīloi paʻewa vestibular nuclei. Ke phylogeny vestibulotserebellum o ke kahiko loa o ka cerebellum.

Paleotserebellum (spinotserebellum). Ua nā ka waena oo? O ka cerebellar cortex a me nucleus o ka halelewa, a me probkovidnye spherical Kora naʻEsau. He aha ua hiki maopopo mai i ka inoa, ka mea hookipa mai i ke kumu o lepa mai spinocerebellar'āpana. He 'oe e komo i loko o ka hoʻohui' ia o sensory 'ike i ka Hawaii kauoha, e ka ka hoʻololiʻana o ka Hawaii ōhumu.

Neotserebellum (pontotserebellum). Neotserebellum o ka nui loa ooieoeiiaeuiiai Pauku ec kīloi paʻewa cerebellar hemisphere a me dentate nucleus. Kona inoa hele mai, mai ka nui pili 'o Randy me ka cerebral cortex Via na nuclei o ke alahaka (afferents) a me ka ventrolateral thalamus (efferents). He ua komo nō i loko o ka hoʻolālā o ka Hotele manawa. Eia hou, keia pauku ua komo i loko o ka cognitive hana o ka lolo cerebellum.

Histology o ka cerebellar cortex

Ka wauke o ka cerebellum ua puunaueia i ekolu papa. I ka pahale loko, ahu iho, granular, i ka 5 m 1010 liʻiliʻi, paa i pili aeee i loko o ka palapala o granules. Ka waena, ahu iho, Purkinje ke kelepona hele, ahu iho la i komo ai o kekahi o ka helu o ka nui keena. I ka pahale mawaho, ahu iho, i ka hakakino i o axons a me dendrites o ka granule keena o Purkinje keena a me kekahi mau 'ē aʻe aeeaʻAno. Purkinje aeea, ahu iho 'ano apau loa i ka palena ma waena o ka granular a me hakakino papa.

Granule keena. Loa uuku, densely hoʻopūʻukiʻuki neurons. Cerebellar granule aeee hoike no ka oi ma mua o ka hapalua o neurons ma ka lolo. Mau aeee loaa ike mai mossy olona, a me ka pāhana ia i ka Purkinje keena.

Purkinje keena. Ka mea, i kekahi o na ano koʻikoʻi loa, o aeee i loko o ka mammalian lolo. Ka mea, nāna i hana i ka nui peahi dendrites finely manamana ai keʻano o ka hanaʻana. He noteworthy ia ia mea aneane elua-dimensional dendritic laau. Eia hou, e aʻo i kaʻoihana a pau Purkinje keena ma ka laua. He mea ka mea he nui ooieoeiiaeuiuo ka noʻonoʻoʻole.

Other ano o aeee. Ma waho aʻeo i ka papa kuhikuhi ano (granular a me Purkinje aeee) cerebellar cortex no hoi kekahi mau acee? Iuo oeiia interneurons me Golgi aeea korzinchatuyu a me ka stellate keena.

ka hōʻikeʻana

Ma ka cerebellar cortex mea he kŘpa mea, stereotyped kumu hoʻohālike hoailona EYI uea, i mea ka ia ma ka cerebellum holoʻokoʻa. ʻikepiliʻeʻe i ka cerebellum hiki ke lawe mai i loko o nāʻaoʻao:

1. Mossy puluniu hua mai la i loko o ka nuclei o ka uwapo, ka spinal kaula, brainstem a me vestibular nuclei, ka mea, ke hoʻouna i mau lepa a cerebellar nuclei a granular keena ma ka cerebellar cortex. Ka mea, i kapaʻia mossy olona, aie ana i ke ano o ka "tufted" i loko o kā lākou hui 'ana me ka granular keena. Kēlā me mossy puluniu innervates haneri o ka granulosa keena. Granular keena hoouna axons keu aku, a i ka wauke ili honua. Kēlā me kēia axon lala ma ka hakakino, ahu iho ma ka hoʻouna mau lepa a ma kekahiʻaoʻao. Mau lepa mea ma luna o ka olona, i ka poe i kaheaia ia laua, no ka mea, holo laua i ka pleats o ka cerebellar cortex, ma ke ala ana i synapses me Purkinje keena. Kēlā me laua puluniu ke hele mai ma ka hui 'ana me nā haneri o Purkinje keena.
2. LAZ olona, hua mai la wale nō i loko o ka emi oliva a me ka pū i hiki lāʻau ikiʻai wale cerebellar nuclei a me Purkinje keena ma cerebellar cortex. Ka mea, i kapaʻia e pii no ka mea, o ke ala hou ana o ka axon, a uhi a puni na dendrites o Purkinje keena - e like me ka piʻi akula nō hoʻi kumu waina. Kēlā me kēia Purkinje aeea launa wale ka impulse like ka ikaika, e piʻi mai i ka hoʻokahi puluniu. Haʻalele mossy olona, a me ka laua olona, kēlā puluniu hōʻike ana me ka manway 10 Purkinje keena ma ka waena, e synapses me ka hola 300 o kēlā me kēia halepaahao.

Purkinje aeea o ka wale kumu o ka hoolilo 'ike mai ka cerebellar cortex (nana i ka likeʻole ma waena o ka Purkinje keena, i hoʻolele lepa, mai ka cortex o ka cerebellum a me ka cerebellar nuclei, a hāʻawi aku i ka' ike mai ka cerebellum).

Ano oe i ka manaʻo o ka mea i ka lolo cerebellum. Kona hana i loko o ke kino o maoli loa nui. Paha na kanaka a pau ma luna iho i loko o ka moku'āina o intoxication? No laila, waiʻona Ua ikaika lawa ia ma luna o ka Purkinje keena, i mea no ke aha la, ma ka mea, he kanaka haalele i kona kaulike, aʻaʻole hiki ke neʻe maʻamau i waiʻona intoxication.

A hiki mai keia, ua hiki ke manao nei makou, he nui cerebellum (i ninoaaeyao ma kahi o 10% o ka huina lolo nuipa a) ka nui kūlana i loko o ke kanaka kino hoʻokōʻana.
