Ke kanaka lolo: 'ole

Ke kanaka lolo eaaaony ōhumu a me ka hooponopono ana o nā mea a pau kino oihana i mea nui no ka maʻamau functioning, a me hoʻi iā hana. Makemake, manaʻo, manaʻo - a pau ua pili i ka lolo. Inā keia kino ua ole functioning, he kanaka i ka "laau."

Ke kanaka lolo: characterization

Brain - symmetric 'ole, nae, e like nui no hoi na nā loko. lolo kaumaha i hanau mea ma kahi o ekolu haneri nā huna, ma ka adulthood mea kaupaona kekahi, a me ka hapalua kilograms. E noonoo pono i ka 'ole o ke kanaka lolo, ua hiki koke huai ae mau hemispheres i i pee ai ma lalo hohonu ho okumu. Hemispheric uhi pono'ī nona convolutions, ho'ākea i ka pā medulla. Ma hope - o ka cerebellum, ka lalo - ke kumu, i hele ai i ka spinal kaula. A mai ke kumu, a mai ka spinalʻaha nā aʻalolo lala mai, ka mea o ka ike, mai ka receptors a hiki i ka lolo ua moni loa no ia, ka mea mea no ia i ke kanaka lolo i mau lepa a me na nāʻiʻo a me glands.

I loko o ka lolo i ka keʻokeʻo waiwai aha nā aʻalolo olona, i hoʻohui kekahi mau pauku o ke kino a me ka ho okumu i waena o lakou iho i nā aʻalolo e holo ana i nā nā loko, a me ke oho waiwai ho okumu i ka cerebral cortex, a he kuhikuhi o nā aʻalolo aeea kino. Ke kanaka lolo ua hoomaluia e ka puniu wale no - iwi hihia. Waiwai i loaʻa i loko o ka hui, a me ka iwi pā kaawale ma ekolu leho: i ka puaʻa hiwa paʻa (waho), pahee (Kalaiaina) a me ke olonā i arachnoid. Ke kūpono makahiki ma waena o ka leho ua piha i ka haku mele i 'ano like me ke koko wai koko, CSF (cerebrospinal) wai. Ua hua nui loli i loko o nā ventricles o ka lolo - na cavities loko o ia, kona kūlana - e hoolako i na kanaka lolo me ka nui o ka mahuaola.

Ke carotid arteries hoolako i ka cerebral holo, ka mea, ua mahele ia i ka lalo i ka nui lālā e ana i kekahi mau wahi o ka lolo. Surprisingly, ka lolo noke loaa 20 pakeneka o ke koko ai hoʻolahaʻia i loko o ke kino, eia nae o ka hui, ke kaumaha o ka huina o ke kaupaonaʻana o ke kanaka mea wale 2,5 pakeneka. Together me ke koko a hiki i ka lolo lako me ka o oxygen, ka hoʻolako 'ia loa nui, e like me ke kino o ka iho ikehu me ke koe i loa haʻahaʻa.

Brain keena

Of keena, kapa neurons, ka mea, o ka Central ko mākou hopohopo nenoaiu. Ka mea, e kuleana no ka manaʻoe hana 'ikepili. Ke kanaka lolo kekahi mau mai ka 5 a hiki i 20 ieeeea? Neurons. Ma waho o lakou, ka hui, haawi glial keena, i mea e pili ana i 10 mau manawa i oi aku mamua neurons. Glial aeee i hana i ka iwi o nā aʻalolo'aʻaʻa, a hoʻopiha i ka makahiki ma waena o neurons. Like kekahi'ē aʻe keena, neurons i hoopuniia e ka wai kokoʻili lahilahi. Of keena hohola aku keʻano o ka hanaʻana - axons (ka hapanui pinepine i loko o hoʻokahi hookahi aeea axon lōʻihi mai ka mau o kenimika i kekahi mau mika) a me dendrites (kēlā me kēia neuron nui dendrites, manamana ai ka mea a me ka pōkole).

Ke kanaka lolo: oihana

Conventionally, ka lolo ua maheleia i ekolu na pauku: ka mua lolo, kumu, cerebellum. Ke forebrain Ua maheleia i mau hemispheres, thalamus (sensory nucleus launa mai i ka 'ike mai nā loko, a pū i hiki ia i ka sensory cortex) a me ka hypothalamus (māhele ke kaōhiʻana homeostatic hana), pituitary - nui gland. Hemisphere - i ka nui loa o ka lolo interconnected kino callosum - ulana lole axons. Kēlā me kēia hemisphere i ka occipital, parietal, kino a me ka frontal lobes. Ke kino nā ka medulla oblongata (ka malalo o ke kumu, i ae i loko o ka spinal kaula), na pons (pili i ka cerebellum nā aʻalolo olona,) a me ka midbrain (ma i ka spinal kaula i Hawaii alanui). Ke cerebellum ua aia ma lalo o ka occipital lobes o na hemispheres o ka lolo, ka mea hoʻi iā ke kulana o ke kumu, mau lala, poo, Radio he nui kūlana ma ka hoʻomakaʻia Hawaii mākau.
