Esakha yangaphambili yaye yintoni isebenza lenza

Yangaphambili lelona sebe kakhulu rostral-luvo. Luquka ezi zifaka yobuchopho (i uthinte) kunye ganglia Uhlobo Lokuqala. Nevuthisayo, ukuba kwi uthinte, ibekwe phakathi kwezahlulo ngokungqalileyo ngobuchopho kunye diencephalon. Ukubunjwa ezi zakhiwo enyukliya ziquka ngumongo caudate, iqokobhe, leyo kunye zenza striatum corpus. igama layo ukuba ifumene ngenxa le alternation lomba hina, eyakhiwa iiseli zemithambo-luvo, namhlophe. Ezi zinto, ndawonye ibhola palsy lipholi, leyo kuthiwa inkqubo ifomu striopallidarnoy pallidum. Le nkqubo ezanyisayo, kuquka ebantwini, sisixhobo enkulu yenyukliya kwaye bathatha inxaxheba kwiinkqubo zokuziphatha motor kunye neminye imisebenzi ebalulekileyo.

Ukubunjwa ganglia carcinomas ezi nuclei subcortical ukuba kuqamba zahlukahlukene kakhulu cellular. Le pallidus globus ezi luvo ezinkulu nezincinane. Striatum zeeseli umbutho efanayo. Kwiinkqubo luvo striopallidarnoy ukuya eyenza ukusuka neuron, thalamus, isiqu nuclei.

Zeziphi imisebenzi eziba subcortical?

iinkqubo Kernel striopallidarnoy inxaxheba kuququzelelo motor kunye nomsebenzi motor. Ukukhuthazwa ngumongo caudate, liyajikeleza iintloko ubhalo ukungaphangalali enikina iintshukumo ze iingalo okanye yemilenze izilwanyana. Xa inkqubo ukufunda striatum, kufumaniseke ukuba unendima kwiinkqubo kweentshukumo ngentloko. Ukuluma le sakhiwo iphula iinkqubo kwinkumbulo nokufunda. inkqubo Striopallidarnoy usebenzisa iziphumo inhibitory kwi umsebenzi weentshukumo kwanangamacandelo alo iimvakalelo, ezifana basabela ndlongondlongo.

Amaxolo ye zifaka yobuchopho

Yangaphambili iquka imfundo, ekuthiwa noqweqwe. Kucingwa ukuyilwa cinci ebuchotsheni. Morphologically, lo neuron ubunjwe umcimbi ezingwevu esigquma yonke ingqondo kwaye indawo enkulu ngenxa ezibayeni eziliqela convolutions. Lo mba gray iquka inani elikhulu leseli-luvo. Ngenxa kule inani zobuchopho likhulu kakhulu, inikeza ukugcinwa kunye nokuqhutywa ingcaciso efunyenweyo. Ngokwesiseko inkangeleko ngendaleko, ekwanti uqweqwe yamandulo, endala kunye ezintsha. Ngexesha Ukusombuluka kwentliziyi mammalian ngokukhethekileyo ngokukhawuleza. ixolo yaMandulo kumafa yayo unawo iibhalbhu ukuqgiba kunye amaphecana, ezi tubercles ukuqgiba. Ubume ingxenye endala cingulate gyrus, Amygdala kunye gyrus hippocampal. Le ndawo eseleyo bobabo le kwentliziyi.

Iiseli zemithambo le neuron zicwangciswe ngokwemaleko kunye usilungiselele, lwesakhiwo Uyila layers ezintandathu:

1st - ebizwa eziphilayo, eyakhiwe plexus luvo kwaye ziqulathe ubuncinane inani leseli-luvo.

2 - ebizwa grainy yangaphandle. Liphethe luvo ezincinane iimilo ezahlukeneyo, ezifana iinkozo.

Okwesithathu - ubunjwe luvo pyramidal.

4 - granular lwangaphakathi, ngathi zangaphandle, lenziwa luvo ezincinane.

5th - iqulethe iiseli Betz (iiseli pyramidal giant). Iinkqubo ezi seli (axons) ukwenza iphecana pyramidal, ofikelela ngokwezahlulo caudal kwaye nabaphumelelayo iingcambu phambi kwe umnqonqo.

6 - multiforme iqulathe luvo ezingoonxantathu kunye fusiform.

Nangona umbutho uvaleke le uthinte unezinto ezininzi ukwenza, isifundo eneenkcukacha lalibonisa umahluko ezivelayo imicu, ubukhulu kunye nenani iiseli kunye detritus yazo eyayizalwa. Ngokufunda ingqondo yomntu imephu uthinte yalungiselelwa, equka imimandla 11 52 yasendle.

Mna ndinoxanduva yintoni yangaphambili?

Amaxesha amaninzi amaxolo ubudala nangaphezulu zidityanisiwe. Bayeyona ingqondo ukuqgiba. Yangaphambili likwanoxanduva nastorazhivanie kunye ingqalelo, inxaxheba ngayo yawo. Le nkqubo ithatha inxaxheba kukwenziwa yethuku kunye neemvakalelo. Ekuhloleni isilwanyana, xa Ukurhawuzela ixolo endala kuvela iziphumo ezinxulumene nenkqubo yokwetyisa: ukuhlafuna yokuginya, peristalsis. Ngoko kuyacaca kwakhona ukuba tonsils ibangela utshintsho umsebenzi enyama yangaphakathi (kwizintso, wesibeleko, isinye). Ezinye iindawo uthinte inxaxheba kwinkqubo yokukhumbula.

Kunye ngxenye, indawo limbic kunye yangaphambili (amaxolo wamandulo kunye nabadala) ukwenza inkqubo ingqondo, leyo igcina homeostasis kwaye eqinisekisa ulondolozo lweentlobo.
