Kuti anoumba hunoita nhengo nhatu uye chii chinoshanda nayo anoita

Hunoita nhengo nhatu ndicho rostral bazi tsinga. Inoitwa pakati Hemisférios Cerebrais (the cortex) uye basal ganglia. Ekupedzisira, ari cortex, riri pakati frontal zvikamu uropi uye diencephalon. The Zvinoumba zvenyukireya zvivako izvi zvinosanganisira caudate musimboti, kuti goko, iyo pamwe chete zvinoumba corpus striatum. zita kwayo akagashira somugumisiro pamusoro alternation vachena nyaya, rinoumbwa masero etsinga, uye chichena. zvinhu izvi, pamwe chete chepfungwa rakachenuruka bhora, unonzi pallidum fomu striopallidarnoy hurongwa. Ino zviri mhuka, kusanganisira vanhu, ndiyo mudziyo guru yenyukireya uye rinobatanidzwa dzinotsanagura gwenya maitiro uye nezvimwe zvakakosha mabasa.

The Kuronga basal ganglia vari subcortical nuclei kuva siyana chaizvo cellular sezvamunoita. The globus pallidus makuru uye zviduku Tutsinga tunofambisa mashoko utwu. Striatum Sero ane zvakafanana sangano. For Tutsinga tunofambisa mashoko utwu striopallidarnoy hurongwa kuenda nomunhu kubva cerebral cortex, thalamus, chokumisa nuclei.

Ndezvipi mabasa subcortical nuclei?

Kernel striopallidarnoy hurongwa dzinobatanidzwa gwenya Kufambisa uye motokari basa. Kukuchidzira of caudate musimboti, unotsauka misoro stereotypical hunhu uye kuzunungusa fambisa maoko kana forelimbs mhuka. Mukuita kwokudzidza striatum, vakaona kuti ine basa dzinotsanagura mumusoro kufamba. Kutsamwa mamiriro ichi anotyora dzinotsanagura ndangariro uye kudzidza. Striopallidarnoy hurongwa rine inhibitory zvinosuruvarisa locomotor basa rayo mupfungwa zvinoriumba, dzakadai hasha zvakaitwa.

The omuti of Hemisférios Cerebrais

Hunoita nhengo nhatu zvinosanganisira dzidzo, anonzi goko. Zvinonzi vaiona gotwe paumbwe uropi. Morphologically, kuti cortex rinoumbwa vachena nyaya anofukidza uropi rose uye ane nzvimbo huru nokuda pazvirugu vakawanda uye convolutions. The pfumbu nyaya ine akawandisa masero etsinga. Nokuda kwaizvozvi nhamba synaptic kwokubatana riri guru kwazvo, rine okuchengetera uye kubudiswa mashoko akapiwa. Pahwaro chitarisiko uye shanduka, yoga yekare, akwegura uye itsva goko. Munguva shanduka ari mammalian neocortex yakatanga kunyanya nokukurumidza. kuhukura Ancient wayo sezvamunoita ane olfactory Mabumba uye maturakiti, asi olfactory tubercles. Sechivako yekare chikamu cingulate gyrus, amygdala uye hippocampal gyrus. The nharaunda asara ndowenyika neocortex.

Masero etsinga pakati cerebral cortex vari akarongwa akaturikidzana uye nomutowo wakafanira, ari mamiriro Anoumba matanhatu akaturikidzana:

1st - inonzi samolecular, kuumbwa plexus tsinga fibers uye iine risingamboshandisi nhamba masero etsinga.

2nd - inonzi chokunze grainy. Inoitwa Tutsinga tunofambisa mashoko utwu duku maumbirwo siyana, rakafanana mbeu.

Third - rinoumbwa pyramidal Tutsinga tunofambisa mashoko utwu.

4th - womukati granular, kufanana rokunze layer ine Tutsinga tunofambisa mashoko utwu duku.

5th - rine Betz masero (hofori pyramidal masero). Dzinotsanagura izvi pamakamuri (axons) kuumba pyramidal turakiti, iyo inosvika uye chinopinda pamberi midzi migove caudal pamusoro musana.

6th - multiforme ine Tutsinga tunofambisa mashoko utwu mativi uye fusiform.

Kunyange zvazvo Neural sangano iri cortex anezvakawanda kuita, kuongorora uwane zvakaratidza kusiyana kuti anowanika mune fibers, kukura uye nhamba masero vavo branching detritus. Nokudzidza uropi cortex mepu rakagadzirwa, izvo zvinosanganisira kumatunhu 11 uye 52 yesango.

Ndini ndakonzera chii hunoita nhengo nhatu?

Kakawanda vakwegura uye vakura kuhukura vasanganiswa. Vanoumba olfactory uropi. Hunoita nhengo nhatu zvakare anokonzera nastorazhivanie uye kutarisirwa, paChikoro autonomic siyana. The Hurongwa anotora chikamu pakugadzirwa nezveuchenjeri maitiro uye manzwiro. In kuedza mhuka, kana kugumbuka yekare nemakwati ngapaonekwe migumisiro chokuita zvomudumbu maitiro: dög, pakuparadza, peristalsis. Uyewo kunovhiringidza kuti tonsils kunokonzera kuchinja mashandiro zvomukati (itsvo, dumbu, dundira). Zvimwe nzvimbo cortex zvinobatanidzwa nedanho nomusoro.

Pamwe hypothalamus, chikamu ichocho ndicho chinoita nzvimbo uye hunoita nhengo nhatu (vekare uye vakwegura nemakwati) kuumba chikamu ichocho ndicho chinoita hurongwa, iyo anoramba homeostasis uye kunovimbisa pakuchengetedza kwemarudzi.
