Hanganga Reticular. Ko te hononga ki te tauhohe nekeneke

Brainstem reticular hanganga ko te hanganga o te plexiform, plurality o ngā hanganga neural, kei roto i ngā wāhanga pokapū (thalami, midbrain me medulla). Neurons e hanga ai ki runga, rerekē i roto i te rahi, roa neurite, hanganga. Whakanui ratou te mumu mātotoru.

Functions o te hanganga reticular

e pā ana Hanganga te ki te roro tuarongo, ua, uho i roto i nga tuakoi kaka, te limbic (whakarato i te tauhohe tino nui i roto i te tinana) te pūnaha. I roto i te hanganga o te mata taunekeneke e haere ake (afferent) me te heke (efferent) ngātere. Ka taea e te ngātere porotītiti ka katia iahiko neural. I roto i tenei take, ngā rōpū, tamau i roto i te neurons hanganga reticular i etahi taumata. Ko te hua ko te tetahi fafauraa ki nga mahi o ngā tari o te pūnaha io pokapū. Te huri i te tohu o te excitation o kawea te tuakoi kiri te hanganga mata.

hanganga Reticular ngā rohe e taea o te whakarato ngä te pānga inhibitory i runga i tauhohe nekeneke tuaiwi ranei.

Hoki te wā tuatahi kitea te hononga i waenganui i te reflexes filosilivá me whakaihiihitanga o ngā wāhanga o te hanganga mata i I. M. Sechenovym. I muri, te Megounom neurophysiologist American ki te āwhina o te tokotoko i mārama whakaahua e te mātakitaki o Sechenov.

Ko te kupu, ka whakaongaonga hiko o te parae medial i roto i makimaki pohe to me te ngeru i reira ko te mutunga oti o te kaupapa, ka rite ki te pūpū, a ka ai whakaongaonga o ngā rohe nekeneke o te uho kaka. Ko te kupu tītohunga wahia katoa e whakaoho te hanganga reticular, kua oti ritenga, he më i roto i te natura.

A, no te kitea ki te lateral rohe hanganga reticular i te taha, te faaohiparaa i te rohe pānga inhibitory kitea ngä pānga i runga i ngā mahi nekeneke tuaiwi.

taea ki te mahi i runga i ngā tūmomo mātauranga filosilivá te hanganga reticular he.

Me kï reira e te rohe o te hanganga mata, nona nei ngä pānga i runga i ngā mahi nekeneke toro anteriorly. Ko te kupu, e hipokina ana e ia te rohe e kore e anake o te oblongata medulla, ko te midbrain me Pons.

Ka taea e te mātauranga Net pā oro uaua. tuwhera ana tēnei ofa'i tūnga R.. whakakitea neurophysiologist Swedish e pā te hanganga reticular te mahi o neurons kama nekeneke. Ratou axons haere na roto i te pera-ka karanga "intrafuzarnym" kaka uaua, me te faaohipa i te wāhi nui i roto i te ture o te wāhanga o te nekehanga tinana me āraitia te.

Ka taea e whai i te mana whakaongaonga i runga i te āhua te whakatakiruatanga o o te uho kaka wāhi rerekē o te hanganga reticular, te mahi tahi katoa o tona rohe.

kawea te pupuri i mahi hanganga mata me te tūtohutanga ki ngā āhuatanga matū komuhumuhu i roto i te toto i roto i te āhuatanga humoral (te hauhā, catecholamines, etc ..). Tenei, i roto i te tahuri, whai wāhi ki te tuitui o te hanganga reticular i te ture o etahi mahi autonomic.

Me kï reira e te ako o te hononga o te hanganga mata ki ētahi atu hanganga subcortical, tukua ana e ia ki a tatou te whakamahine i te āhuatanga o tikanga neurophysiological o te āhua o āhua takitahi (mamae, kia mataara, moe, ara maiteraa, āhua aronganui me te whakahihiko, me ētahi atu). Whakamahi i roto i ngā akoranga Medicine heheu tīkina takitahi o pathologies CNS, te tautuhi i te huarahi hou ki etahi raruraru hauora.
