ʻO ka ʻōnaehana ʻōnaehana ke ʻōnaehana kamaʻilio o loko o ke kino. Hana ʻia i loko o nā kino o ke kino. Lawe nā hunaola nerve i ka ʻike ma o ka ʻike o ke kino: pā, ʻono, ʻaʻala, ʻike maka, a me ke kani. Unuhi ka lolo i kēia mau hōʻailona ʻike e hoʻomaopopo i ka mea e hana nei ma waho a ma loko o ke kino. ʻAe kēia i kahi kanaka e hoʻohana i ko lākou kino e launa pū me ko lākou kaiaulu a puni a kaohi i kā lākou hana kino.

Paʻa paʻakikī ka ʻōnaehana ʻōnaehana. Hilinaʻi mākou iā ia i kēlā me kēia lā e kōkua iā mākou e noho olakino a palekana. No ke aha mākou e mahalo ai i kā mākou ʻōnaehana hopohopo? E heluhelu i kēia 11 mau ʻike leʻaleʻa a ʻike ʻoe i ke kumu:

1. He piliona ko ke aʻa aʻa o ke kino

Loaʻa i nā kino o kēlā me kēia kanaka nā piliona o nā ʻāʻī nerve (neurons). Aia ma kahi o 100 biliona i ka lolo a me 13.5 miliona i ka iwi kuamoʻo. Lawe nā neurons o ke kino a hoʻouna i nā hōʻailona uila a me nā kemika (ikehu electrochemical) i nā neurons ʻē aʻe.

2. Hana ʻia nā neurona ʻekolu mau ʻāpana

Loaʻa nā neurona i nā hōʻailona ma kahi ʻāpana antennae pōkole i kapa ʻia ka dendrite, a hoʻouna i nā hōʻailona i nā neurons ʻē aʻe me kahi ʻāpana kaula lōʻihi i kapa ʻia ʻo axon. Hiki i kahi axon a i ka mika ka lōʻihi.

I kekahi mau neona, uhi ʻia nā axons me kahi ʻāpana lahilahi o ka momona i kapa ʻia ʻo myelin, a he insulator ia. Kōkua ia i ka lawe ʻana i nā hōʻailona nerve, a i ʻole nā ​​impulses, i lalo o kahi axon lōʻihi. ʻO ka ʻāpana nui o kahi neurona i kapa ʻia ke kino pūnaewele. Loaʻa iā ia nā ʻāpana nui āpau o ka pūnaewele e ʻae iā ia e holo pono.

3. ʻOkoʻa paha ka nānā ʻana o nā Neurona

Hele mai nā Neurona i nā ʻano like ʻole a me nā nui e pili ana i kahi o lākou i loko o ke kino a me nā mea a lākou e papahana ai e hana. Loaʻa nā neurons sensory i nā dendrite ma nā wēlau ʻelua a pili ʻia e kahi axona lōʻihi i loaʻa kahi kino pūnaewele i waenakonu. He kino pūnaewele ko nā neurons moto ma kekahi wēlau a me nā dendrite ma kekahi wēlau, me kahi axon lōʻihi i waenakonu.

4. Hoʻonohonoho ʻia nā Neurons e hana i nā mea like ʻole

ʻEhā ʻano o nā neurons:

• Sensory: Hāʻawi nā neurons sensory i nā hōʻailona uila mai nā ʻaoʻao i waho o ke kino - {textend} nā gland, nā mākala, a me ka ʻili - {textend} i ka CNS.
• Mīkini: Hāpai nā neurons motor i nā hōʻailona mai ka CNS a i nā ʻaoʻao i waho o ke kino.
• Nā mea loaʻa: ʻIke nā neurons receptor i ke kaiapuni (kukui, kani, hoʻopā a me nā kemika) a puni ʻoe a hoʻolilo iā ia i ikehu electrochemical i hoʻouna ʻia e nā neurons sensory.
• Nā Interneurons: Hoʻouna nā Interneurons i nā leka mai kekahi neuron i kekahi.

5. Aia ʻelua ʻāpana o ka ʻōnaehana hopohopo

Māhele ʻia ka ʻōnaehana haʻihaʻi kanaka i ʻelua ʻāpana. Hoʻomaopopo ʻia lākou e ko lākou wahi i loko o ke kino a hoʻopili pū i ka ʻōnaehana waena (CNS) a me ka ʻōnaehana ʻōnaehana ākea (PNS).

Aia ka CNS ma ka iwi poʻo iwi kuamoʻo a me ka vertebral. Hoʻopili pū ʻia nā aʻalolo i ka lolo a me ka iwi kuamoo. ʻO nā aʻalolo āpau i koe i nā ʻāpana ʻē aʻe o ke kino he ʻāpana ia o ka PNS.

6. Aia nā ʻano ʻelua o nā ʻōnaehana hopohopo

He CNS ko ke kino o kēlā me kēia. Akā he ʻōnaehana manawaleʻa a manawaleʻa hoʻi ia.Mālama ka ʻōnaehana ʻōnaehana manawaleʻa (somatic) i nā mea i ʻike ʻia e ke kanaka a hiki ke kaohi i ka ʻike, e like me ka neʻe ʻana i ko lākou poʻo, nā lima, nā wāwae, a i ʻole nā ​​ʻāpana kino ʻē aʻe.

ʻO ka ʻōnaehana ʻōnaehana ʻole (vegetative a i ʻole akomi) ʻōnaehana ʻōnaehana e kāohi i nā kaʻina hana i loko o ke kino e kaohi ʻole a ke kanaka. Hana mau ia a hoʻoponopono i ka helu o ka puʻuwai o ke kanaka, ka hanu ʻana, ka metabolism, ma waena o nā hana kino koʻikoʻi.

7. Ua wāwahi ʻia ka ʻōnaehana hoʻoikaika ʻole i ʻekolu mau ʻāpana

Hoʻokomo pū ka CNS a me PNS i nā ʻāpana manawaleʻa a me nā ʻāpana manawaleʻa ʻole. Pili kēia mau ʻāpana i ka CNS, ʻaʻole naʻe ma ka PNS, kahi e hana maʻamau ai i nā ʻāpana like ʻole o ke kino. ʻO ka ʻāpana pili ʻole o ka PNS me nā ʻōnaehana aloha, parasympathetic, a me nā ʻōnaehana nūhou enteric.

8. He ʻōnaehana hopohopo ko ke kino no ka hoʻomākaukau ʻana i ke kino no ka hana

ʻ tellslelo ka ʻōnaehana ʻōnaehana aloha i ke kino e hoʻomākaukau no ka hana kino a me ka noʻonoʻo. Hāpai ia i ka puʻuwai e paʻi ikaika a wikiwiki hoʻi a wehe i nā alaloa no ka hanu maʻalahi. Hoʻomaha iki ia i ka digestion i hiki i ke kino ke nānā i ka hana wikiwiki.

9. Aia kekahi ʻōnaehana hopohopo no ka kaohi ʻana i ke kino i ka maha

Mālama ka ʻōnaehana pīhoihoi parasympathetic i nā hana o ke kino ke hoʻomaha ke kanaka. ʻO kekahi o kāna mau hana e pili ana i ka stimulate digestion, activating metabolism, a me ke kōkua ʻana i ke kino e hoʻomaha.

10. Aia kekahi ʻōnaehana hopohopo no ka kaohi ʻana i ka ʻōpū

Loaʻa i ke kino kona ʻōnaehana ʻōnaehana e kaohi wale i ka ʻōpū. Hoʻonohonoho ka ʻōnaehana ʻōnaehana enteric i ka neʻe ʻana o ka ʻōpū ma ke ʻano he ʻāpana o ka digestion.

11. Hiki ke hacked kou hopohopo kahua

ke hoʻomohala nei i kēia manawa i nā ala e "hack" ai i ka ʻōnaehana paleʻea, e loaʻa ana ka hiki ke kaohi i nā hunaola o ka lolo me ka uila o ke kukui. Hiki ke hoʻolālā ʻia nā hunaola i ka hopena i ka malamalama ma o ka loli ʻana o ka ʻaoʻao.

Hiki i ka hacking ke kōkua i nā ʻepekema e aʻo e pili ana i nā hana o nā hui like ʻole o nā neurons. Hiki iā lākou ke hoʻohana i nā pūnaewele lolo i ka manawa like a nānā i ko lākou hopena ma ke kino.
