Mahi urutau-arataukai

Ko tētahi o te pūnaha io pokapū, autonomic huaina, ngā o te maha ngā wāhanga. Ko tētahi o ratou ko te pūnaha io pukuaroha. āhuatanga Taumahi, me te morphological tukua wehea reira ki te maha ngā wāhanga. Ko tētahi atu Tari NS autonomic - te pūnaha io parasympathetic. I roto i tenei tuhinga, whakaaro tatou e taua te mahi arataukai.

Mō CNS

I roto i te ora o tetahi kaiao ora ko te maha o ngā mahi nui e whakamana e te pūnaha io tino. Na reira, he mea mahu'inga nui rawa. Ko te pūnaha io iho he tino matatini, me te whai wāhi tari rerekē, he maha ngā momo. te mauria atu ia o ratou he maha o ngā āhuatanga motuhake āhuatanga o ia o nga tari. He meka ngā ko e i whakamahia tuatahi te ariā rawa o te pūnaha io pukuaroha i roto i 1732. I roto i te timatanga, i whakamahia te wā ki te tautapa i te pūnaha io autonomic katoa rite te katoa. Heoi, ki te whanaketanga o te rongoā me te haaputuputuraa o te matauranga pūtaiao, ka mārama e te pūnaha io pukuaroha, he mahi wehe ki te mahi kahu whānui. Ko Ko te aha timata te ariā ki te te whakamahi anake i roto i te faatura o tetahi o nga wehenga o te pūnaha io autonomic. ka mahi arataukai o te pūnaha io kia aroaro i raro.

NS pukuaroha

Ki te noho koutou i runga i ngā uara motuhake, riro te reira mārama e āhuatanga te pūnaha io pukuaroha e rawa ngā āhuatanga - he reira te kawenga mō te tukanga kohi rauemi o te tinana, me te mobilizes ona ope ā-i roto i te hui o te ohorere. Ki te whakatika ake i te hiahia, te pūnaha pukuaroha nui faarahi te ururua o ngā rauemi pūngao ki te tinana tonu mahi noa, me te ki te mahi i etahi mahi. I roto i taua take, ka reira he kōrero e pā ana ki te meka e kua huna te tinana tangata āhuatanga, kua matau ai te tukanga. Herenga o te tangata tei runga i te aha ki te pūnaha pukuaroha akakoromaki i to ratou mahi.

Ko te parasympathetic NA

Heoi, meinga enei tikanga ahotea nui ki te tinana, a kore e taea te mahi i te reira mo te wa roa i roto i tenei āhua i te aratau noa. Here faufaa nui ko te pūnaha parasympathetic, e tae mai ki te tākaro, me te taea ki a koe ora me te whakaora i ngā rauemi o te tinana, e i roto i te tahuri kore taea whakawhāiti ona taea. tukua nga pūnaha io pukuaroha, me te parasympathetic te tinana tangata, ki te mau tonu te mahi noa i roto i ngā āhuatanga rerekē. He pā ana tata ratou me he tautoko ki tahi i te tahi. Ko te aha te auraa te reira mahi arataukai o te National Assembly? I runga i tenei i muri mai.

pūrere kikokiko

He he hanganga kaua uaua, me te branched pukuaroha NA. Kei tōna wahi pokapū i roto i te ua, me te hono karere piringa nga ngā kōpuku me raru o te tinana. E hono nga hopearaa io katoa o te pūnaha pukuaroha ki te plexus me hāngai i roto i te kopa innervated.

Ko te wahi piringa o te pūnaha i hanga e te momo o tairongo neurons efferent he tukanga motuhake. He mamao i te ua ēnei tukanga, ā, e kei te nuinga i roto i te kōpuku paravertebral me prespinal.

Ko te mahi o te pūnaha pukuaroha

I kï hoki, e te faaitoitoraa o te pūnaha pukuaroha kei roto i te whakapā atu ki te tinana i roto i ngā āhuatanga taumaha. karanga ētahi puna reira urupare pūnaha io pukuaroha. Tenei ingoa e pā ana te ki te meka e whai wāhi ai te putanga o te tauhohenga motuhake ki te pānga i te waho. Ko tona mahi arataukai.

Ki te tūtaki koe i te āhuatanga taumaha, te repe adrenal te huna hoki Adrenaline timata tonu. Ko ia te taonga matua e taea te takitahi ki te whakautu pai me te tere whakautu ki te ahotea. kia puta te āhuatanga rite i roto i mahi. hanga Adrenaline reira māmā ki te akakoromaki i reira. whakarei ake Adrenaline te mahi o te pūnaha pukuaroha, a reira, i roto i tahuri, whakarato rauemi mō te kohi pūngao nui haere. e kore te mea he puna pūngao ano secretion o Adrenaline, engari whai wāhi ki te whakaongaonga o whekau tangata me rongo.

Ko te mahi matua

Ko te mahi matua o te pukuaroha NA ko te mahi urutau-arataukai.

Kia whai whakaaro ano tatou i te reira i roto i te kōrero atu.

Koiora wa roa nui ki te kia whakaatu i e te pūnaha io somatic anake whakarite te ture o te mahi o te momo uaua kōhiwi. ngaueue tenei whakapono i tae noa ki te tīmatanga o te rau tau 20.

meka mohiotia e puta i muri roa rohirohi whakamahi uaua. Ko te kaha o te contractions āta memenge, a kia mutu ratou i toe. Ko te tōtika o te uaua e whangai ana ki te ora i muri i te okiokinga poto. Hoki te wa roa e mōhiotia nga take mo tenei āhuatanga.

I roto i te 1927, empirically kitea Orbeli L. A. te whai ake: ki te ki te ripa kawea te poraka ki te mutunga oti o te kaupapa, e ko, tae noa rohirohi i te rongo auroa ki te nekeneke karere, a ka, kahore hoki e mutu te whakaongaonga pūkaha, timata whakarara ki mukākā te karere me te pūnaha pukuaroha, ka tino kia hohoro whakahokia mahi. Huri i te reira i roto i, te pānga hononga i runga i te pūnaha pukuaroha taui te taumahinga uaua e ngenge. Puta te whakakore ngenge me te whakahokia tona hauora. Ko te mahi arataukai o ngā pūtau io tenei.

Pānga i runga i muka uaua

Kua kitea Scientists e nga raru o te pūnaha pukuaroha i te mana kaha i runga i te muka uaua, i roto i ngā, i runga i to ratou kaha ki te whakahaere o nāianei hiko rite te pai kia rite ki te taumata o excitability o te karere nekeneke. I raro i te mana o te innervation pukuaroha o te huringa i roto i te hanganga me te nui o pūhui matū i roto i roto i te uaua, me te whai wāhi nui i roto i te whakatinanatanga o ona mahi. Taua pūhui ngā waikawa lactic, glycogen, creatine Phosphate. Rite tonu ki enei raraunga, kua riro te reira taea ki te faaoti e te pūnaha pukuaroha whakaongaonga te takanga o etahi huringa tinana, me te matū i roto i te uaua kōhiwi, he pānga e fakatonutonu i runga i te tūtohutanga o te uaua ki te ponana nekeneke puta e tae mai i te muka o te pūnaha somatic. faa'aano e pūnaha kaungāongo'i te kiko uaua ki te mahi pikaunga e taea puta i roto i te mau huru rerekē. I Ua ite te reira e whakarei te mahi uaua ngenge te i raro i te mana o te karere pukuaroha i roto i te mana nui haere rere toto. Heoi, e kore i enei ngā whakapumautia tenei tirohanga. Ko e founga te arataukai tenei mahi o te neuron.

Na roto i rangahau motuhake i kitea ai e te excitability kaungāongo'i tika i roto i ngā whai tuaiwi kore. Ko te kupu, ko te mana o te momo pūāhua pukuaroha i roto i te uaua kōhiwi i roto i anake te tūringiringi o te takawaenga ranei ētahi atu matū e kua tohaina terminals pūnaha vasomotor kaungāongo'i. Ka taea te whakapumautia i tēnei mutunga ngāwari i te whakamātau ohie. Ki te ki te uaua hoatu i roto i te otinga ranei perfuse reira ki te oko, a ka tīmata ki te pānga i runga i te karere pukuaroha, te otinga perfusate ranei kite te āhua unidentified o te taonga. Ki te whakaurua enei matū ki ētahi atu uaua, ka meinga e ratou te pānga o te āhua pukuaroha.

Kei te tautokona hoki te tikanga taua e te wā moe nui, me tona roa nui i mua i te pānga. Hoki te putanga o te mahi urutau-arataukai kore e rapua e te wa roa i roto i aua whekau, e ua horo'ahia i te kārangirangi kaungāongo'i hāngai, pērā i te ngakau, me te tahi atu whekau.

tautoko meka

Ko te meka whakamatautau ture neurotrophic i te pūnaha pukuaroha, i whiwhi ai i te whakahaere rangahau ngā i runga i te kiko uaua kōhiwi. ngā rangahau kikī mahi, denervation, houtanga, ripeka-hononga o nga raru ko e e hono ana ki te momo rerekē o muka uaua. Ka rite ki te hua o te rangahau whiwhi mutunga e whakahaere mahi arataukai tukanga pūkoro e mau tonu hanganga uaua noa me te whakarato me te reira i roto i te mahia o kawenga motuhake. whai wāhi ēnei tukanga pūkoro tinana ki te faaho'iraa mai o te rauemi tika i muri i mutu uaua mahi. Ko te mahi o taua tukanga e tika ana ki te maha o ngā matū ture koiora. He he taunakitanga e hoki hiahia te putanga o ngā mahi arataukai ki te kawe i te rauemi e tika ana i te tinana pūtau ki te tinana whakahaere.

Ka taea te whai whakaaro mai te reira i rite te tikanga mohio, me te meka e kore te te uara o neurotransmitters iti ki te whai wāhitanga i roto i te tukanga o te whakawhiti whakauka. Ratou pā hoki nga oranga o tinana oaoa whai wāhi i roto i te supply pūngao o te kopa.

Hei tauira, kei te whai wāhi catecholamines i roto i tenei tukanga, kia rite ki te whakatinanatanga o te mahi arataukai. I roto i te piki te taumata toto energosubstratov, e tika ana ki te mana tere, me te kaha i runga i ngā tukanga pākia e.

mutunga

Kei te mohiotia te reira e tairongo muka io whakaatu hoki pānga urutau-arataukai. Kua kitea Scientists e i roto i te hopearaa o muka rongo i roto i katoa o matū neuroactive āhua, pērā i neuropeptides. Ko te tino noa R-neuropeptides, me te peptides e kua e pā ana ki te ira calcitonin. Taua peptides i muri i te wehenga i te hopearaa io taea whai i runga i te mana arataukai a tawhio noa kiko.
