Uila puhi: liluwelo ano

Uila puhi - iʻa a paha ke ka hookuuiaʻikena anakahi uila o 650 V. kēia anakahi uila hiki ia i ke kill me kanaka i mea kokoke. Nā kiʻie oʻo uila puhi kīnā aneane ekolu mika ma ka lōʻihi, a laila, e like me kona mānoanoa mea e pili ana i umi mau kenimika. Ekolu uila nā loko noho kokoke 80% o ka puhi kino, i ka i koe 20 e ku ma nā kino hoʻokō i kahi e pōʻino papa (nā'ōlelo, ka hanu, digestion, etc.).

Nō kāu, wai i noho ma ka uila puhi, ilihune ma ka o oxygen, nae, ia mea,ʻaʻole pioloke. No ka nui o na umi tausani o nā makahiki o ka evolution, aʻo ihola ia e hanu O2. Young conger hiki maopopo ike, nae, ma na makahiki, i kona eyesight Ua hikiwawe loa deteriorating. It E e hoʻomaopopo i ka mea i hoʻolilo 'ia i loko o ka mea ana i ke ola, i ole kona mau maka maopopo kōkua maikaʻi. Huehue hoʻokuʻu akula nawaliwali pou impulses (40-50 C), haʻahaʻa-anakahi uila hookuuiaʻikepili e kōkua loaʻa iā lākou kā lākou mea pio.

No a pau ka iʻa? Aaoa mea wale hiki ke paha keia dala o ka mana e hiki lolo paha hoi e pepehi i kekahi kanaka. Special Electro hookauwa iʻa no ka kohoʻia, pale aku, iʻiʻo holoholona hihiu, a me ka launa pu. Pou hookuuia e hiki no ka hoopakele ana ma kahi o 250 laha 'o ka iʻa, nae, elua wale ke ano o na iʻa ('īnikiniki a me nā kukuna) paka i ke kauoha no ka mana i ke pepehi i ke kanaka. Uila ia lŘlŘ i loko o ke kino o nā holoholona, me nā kānaka. Pou impulses pū i hiki ma ke aʻalolo olona, ma ka lolo neurons i hala likeʻole no lepa i ana i loko o ke kino. Ma ke kino o'īnikiniki a me na kukuna he nui ikehu i ka mea hiki ke hana ia me ka mea kaua. Back ma ka hopena o ke kenekulia 18th, ua loaʻa ka noiʻi i nā aʻalolo impulses i elektrohimicheskuyu ano. Ma nā hua'ōlelo, a hiki i loko o kēlā mau makahiki i kakahiaka nui, ka mea i hoao i ke aʻalolo lepa - i ka neʻeʻana o Ion ma kaʻili lahilahi neurocyte. Ma koena ole inactivity o konaʻili lahilahi aeee i ka hopena maikaʻiʻia (i loko o ka waihoia Ion K) i, a mawaho loaa nā hopena maikaʻi a me ka maikaʻi Ion (paʻakai a me ka potasiuma Ion). Ma ke kaʻina hana o ka anal o ka paʻakai Ion i loko o ka halepaahao Loaʻaʻia ua hoʻololi i ka maikaʻi. Ma ka maʻamau noho aie ana i ka hana o ka "paʻakai EII ni" ka halepaahaoʻia pakele o ka paʻakai Ion.

puhi iʻa ua pono hakuloli i ke ola i loko o ka noho pio ana, ia mea he pinepine noho o ka hale aquariums. Kekahi mau kânaka ÷ ike i ka hanana hiki o'īnikiniki ka hoʻohana pu u kukui, kaula a i hōʻike 'ia ma ka aquarium. Kaʻimiʻana Loaʻaʻia pio (ia liilii hānai'āpana), uila puhi hoʻomaka hoʻomakaʻia ka pila hookuuia ma ka koʻana koko meakino. E lohe kūpaʻa halulu kūpono electrodischarges ma aquarium huapalapala kani amplifiers. Lawelawe ana ia i Ka Hānai Ā Huhu - ia mea he pilikia loa.

Ka hanana hiki ana o ka puhiʻepekema i këia no ka oi ma mua o ke kenekulia. I World War II'īnikiniki hoʻohana 'ia i loko o ia mea ma ka hopena o nā aʻalolo kinoea, ka paleʻana EYI o impulses, a pela hiki pili nui nā loko ooieoeiiaeuiiai hana (naau, maʻiʻaʻai, digestive nenoaiu). Nā aʻalolo kinoea inhibit cleavage o acetylcholine (uwao) ma hope o ka mea ālai 'o ka "paʻakai EII ni" neuron. E like me ka rula, acetylcholine i loko o ke kino koke ma hope o ka mahae, pehea e hana kona iniiaiie kuleana pili i. Ke hydrolytic kaʻina ua noho mana ana ma ka'ūhū (cholinesterase). Pono nā aʻalolo kinoea aeie i ka ha awina o ka olelo mai'ūhū.

Electro puhi wehewehe aku e nui ka maʻiʻo o ka cholinesterase. Koa hoʻomalu Ua hoʻohana uila'īnikiniki me ke kumu o ka'ūhū, i ua pono no këia i keʻano papa hana o ka hana o nā aʻalolo kinoea ma luna o ke kanaka kino.
