He aha nā neurons? Ke 'ole a me ka hana ana o neurons

Ke kanaka kino o ka luna ''ōnaehana i loko i ka hana a ua āpau i komo i na mea he nui kaawale eiiiiiaiou a me nā huahelu. Externally, o ka mea kino he mea haʻahaʻa, a me ke ahiahi primitive. Eia naʻe, ina oe e nanaʻoi a me ka ho'āʻo e kuhikuhi i nā manaʻo no ka i ka mea, he AaOIeIOUIeXAOAaIN ma waena o ka mea okoa kino, alaila, e hele mai i ka mua ko mākou hopohopo nenoaiu. Neuron, i mea no ka papa kuhikuhiE iaea ooieoeiiaeuiiai pa alima o ka 'ole, hana like me ka lēkio leo o Nine Inch a me ka pou impulses. I loko nō o ka mawaho similarity i kekahi keena, e hanaʻia oi eiiieaena a me ka noho pilikia hana nona ka kākoʻo mea nui no psychophysical kanaka haʻawina. No ka mea naʻauao o kēia mea loaʻa, e hana mai i kona manao, e hana ana i nā loina a me nā Pahuhopu.

He aha nā neurons?

A neuron mea he hana kūikawā aeea i ka hiki o ka loaa ana a me ka aaioee 'ike i loko o ke kaʻina hana o ka AaOIeIOUIeXAOAaIN me nā mall a me ka ooieoeiiaeuiuo huahelu o ka'emi ko kahua. Ka helu o kēia mau receptors ma o ka lolo, he 10 ¹¹ (hoʻokahi haneri ieeeea?). Penei kekahi neuron e komo hou ma mua o 10 tysyach synapses - sensory a hāʻule pahū wale, a me na mea o ka i intercellular hui 'ana ana. Ua haawiia i ka mea i hiki e manaʻo i kēia mau kumu i palaka i hiki hoahu 'ike, he mea hiki ke manao nei makou, i ka manawa kūpono o kanaka lolo ai ke komo nui dala o ka' ike. I kapaʻia he neuron mall pa alima o ka'emi'ōnaehana, hoomaopopo ana i ka hana o ka makaukau. I ua, manao keia halepaahao e e like me ka multifunctional hehee ai no ke kākoʻo pāʻoihana o nā pilikia.

No neural keena

Inā mākou e hoohalike i ka 'ole o ka neurons me nā keena, ua hiki ke loaʻa i na mea like. Eia naʻe, ma ka hua'ōlelo o ka functionality,? Acaeoey a me nā loina o kēia kūlana oihana mua o ke kanaka kino. Ke kumu nui hiʻona o ka neurons mea i koke ma hope o ka hanau ana o ko lakou mau keena oki i ka paʻi. Kēia wehewehe i ka mea i like ko lakou ulu ana mua i ke hoemi i ka helu ana o receptors i loko o kekahi mau wahi o ka lolo. Eia naʻe, i kekahi mauʻano o neurons ma hope o ka hānau hiki me ka nui loa hoonui hou pili 'o Randy, i hoonui ae i ko lakou mau ooieoeiiaeuiiai haʻawina. Aia nā hiʻona i loko o ka 'ole. Ka nui, e hoike ana i ka hana o ka neural aeea ua initially hoʻomōhala ma luna o ka palapala a Pahuhopu. No keia kumu, kona 'ole hoʻolako i ka helu o ka kūikawā keʻano o ka hanaʻana i nā kuleana no ka pū i hiki a me ka loaa ana no lepa.

Ka 'ole o nā neurons

Ke kumu o ke kelepona hele kino, ma loko a mea he organelle a me ke kapa komo iā ia kāna mau 'ōlelo me ka kūikawā halepaahao. Kanaka noonoo keʻano o ka hanaʻana keena hōʻike axons a me dendrites. Kēlā me kēia neuron mea i ka luna 'a hoʻomohala i ka cytoskeleton, i komo i loko o ka keʻano o ka hanaʻana. Kēia hehee ai kōkua e malama i ke kelepona hele kinona, a a me keia hoolilo hana hanaʻia organelles neurotransmitters. Pela kēlā aeea i ka 'ole, akā, e ĸokoĸa ana nä pane ma ka nui. No ka laʻana, i ke kino ke lilo i neuron i loko o ke anawaena mai ka 3 a hiki i 130 microns. I nā aʻalolo receptors e oko i loko o ka helu o keʻano o ka hanaʻana. Kekahi specimens, no kekahi laʻana, i mau dendrites, oiai kekahi poe i ike okoa lālā e hoʻonui i ka loaa hou nui o ka 'ike. ʻO ia pili i ka axons, a ĸokoĸa ana nä pane ma ka lōʻihi.

Ke kaʻina hana o ka ho okumu i neurons

Kēlā me kēia neuron i ka halepaahao-, hoʻokomo, a ua pani ana ma mua ka mea, lilo iho la ka mua OAAIeOO keʻano o ka hanaʻana. Naʻe, i nā hiʻona o kēia kaʻina e poorly maopopo. E like me ia he nui noiʻi, ka axon akaka mua, i ukali ia e ho okumu ana o dendrites ia ia. I ka pau ana o ka ho okumu i kaʻina he mea ai hanaʻia naʻe, a no hoi ka hoʻomohalaʻana i ka "mawah" i loko o ka puni'aʻaʻa. He nui ke hoomanao i na neurons ma ka'emi ko kahua? Kēia liʻiliʻi mall a me ka iaea ooieoeiiaeuiiai pa alima, nona ka waiwai me ka nānā 'ia e keʻano o ka hanaʻana. Externally, e like me ka lala e hoohalike ai na laau o ka lahilahi spines mānoanoa o ma kahi o 0.2 microns. Pela i microspikes lōʻihi hiki a hiki i 50 microns. Nāʻanuʻu ma waena o ia keʻano o ka hanaʻana piha pleatedʻili lahilahi.

neurons hana

Aia nō kekahi mau mana e hana neurons. Ma 'ana, ka sensory keena oko ma ka pā lonoaʻili i mau stimuli. Mau receptors mau makana i loko o kaʻili, alelo, Muscle, a me ka 'ole. D. ke keena o kēiaʻano ae i ke kanaka, e haha aku ka eha, wela ihola, puʻe, e like me ka pono i ala a me nā ho'āʻo iho au i. Eia naʻe, no ka maopopo loa ana mea na neurons a me ke kumu ka mea i pono, e manaoia ole wale kekahi naoh i stimuli. Eia sensory keena, ma laila nō Hawaii neurons, noho haumāna kahi i ke kino o nāʻiʻo. Aia o kekahi nui pūʻulu o receptors e hana me ka loulou ma waena o Hawaii a me ka sensory keena. Ua interneurons, a hana i ka Central ko mākou hopohopo nenoaiu.

'ano o nā neurons

I ka papa kuhikuhiE Mea Maluna pili i ke kaawale ana o neurons ma ka mall manawa. Ma kekahi, ua hōʻike 'haumana bezaksonnye, psevdounipolyarnye, unipolar, bipolar a me multipolar neurons. Au pono aku nei au i kekahi o kēia mau? Ueo i nō uuku hoomaopopo. Ua pili e bezaksonnym aeee i i Hoʻohui 'pu i loko o ka spinal kaula. hoopaapaa e pili ana unipolar neurons i underway. Aia nā manaʻo i na keena a me ka mea i noho i loko o ke kanaka kino. Inā mākou e kamailio e pili ana i mea na neurons i loko o ke kino, ua Kīwala'ō e kiekie ae like keʻano, a laila e hele mai i ka mua multipolar receptors. Kēia aeea i ka pukapuka o dendrites, a he hoʻokahi axon. Oe ke olelo aku nei au ia 'o he Classic neuron, ka loa, he pono ole i loko o ka'emi ko kahua.

ka hopena

Neural aeee i ka integral ke keʻena o ke kanaka kino. Ua mea ma kēia mau receptors ua hoomakaukau kela la i keia functioning, a me nā haneri o na tausani o Nine Inch transmitters i loko o ke kanaka kino. Ma ka keia kahua o ka? Acaeoey o ka 'epekema, oia ka pane ana i ka ninau e pili ana i mea na neurons, akā, me ka lau a me ka lewa no ka wā e hiki mai discoveries. No ka laʻana, i kēia lā ua nui na manao ma luna o kekahi o na nuances o ka hana, a me ka ulu kūpono 'ana o kēia' ano o ke keena. Akā, ma kekahi hihia, i ka study o neurons o kekahi o na kumu hana o Neurophysiology. Lawa ia e olelo aku i na discoveries hou i loko o kēia kahua e hiki, e hookahe aku i ka malamalama i maikaʻi aoao, e hana na mea he nui ka noʻonoʻo 'kāna hana. Eia hou kekahi, he hohonu naʻauao o neurons hana me nā loina e kōkua e kūkulu i kekahi mea e hoʻoulu noʻonoʻo haʻawina a me ka hoʻoikaika 'ana i iaiyoe i loko o ka hou hanauna.
