Wannan Forms da forebrain da kuma abin da ayyuka shi aikin

A forebrain ne mafi rostral reshe na juyayi tsarin. Ya kunshi da cerebral hemispheres (da bawo) da kuma muhimmi ganglia. A karshen, kasancewa a cikin bawo, located tsakanin frontal sassa na kwakwalwa da kuma diencephalon. A abun da ke ciki na wadannan makaman nukiliya Tsarin hada da caudate tsakiya, da harsashi, wanda tare dokoki da ayyukan marubuta striatum. Its sunan shi ya samu a sakamakon da sãɓãwar m al'amari, hada da jijiya Kwayoyin, da fari. Wadannan abubuwa, tare da cerebral kodadde ball, da ake kira pallidum form striopallidarnoy tsarin. Wannan tsarin a dabbobi masu shayarwa, ciki har da a cikin mutane, ne mai babbar nukiliya na'urar da aka hannu a cikin matakai na mota hali da kuma sauran muhimman ayyuka.

A abun da ke ciki na muhimmi ganglia ne subcortical nuclei da ciwon sosai bambancin salula abun da ke ciki. A globus pallidus ne manyan da kananan neurons. Striatum cell yana da irin wannan shiri. Domin neurons striopallidarnoy tsarin tafi hasken dake fitowa daga cerebral bawo, thalamus, kara nuclei.

Mene ne ayyuka subcortical nuclei?

Kwaya striopallidarnoy tsarin da hannu a motor daidaituwa da kuma mota aiki. Ruri daga cikin caudate tsakiya, yana juya shugabannin stereotypical hali da kuma girgiza ƙungiyoyi daga cikin makamai ko forelimbs dabbobi. A kan aiwatar da nazari da striatum, aka same shi da cewa shi yana rawa a cikin matakai da haddacen ƙungiyoyi. Hangula wannan tsarin warware da matakai na memory da kuma ilmantarwa. Striopallidarnoy tsarin exerts mai hanawa illa da kan locomotor aiki da wani tunanin gyara, kamar da m dauki.

A haushi da cerebral hemispheres

A forebrain hada da ilimi, da ake kira da ɓawon burodi. An dauke ƙarami samuwar kwakwalwa. Morphologically, da bawo aka hada da launin toka al'amarin da ya rufe dukkan kwakwalwa kuma yana da babban yanki saboda da yawa folds da kuma convolutions. The m al'amari kunshi wata babbar lamba na jijiya Kwayoyin. Saboda wannan adadin synaptic sadarwa ne manya-manyan, shi na samar da ajiya da kuma aiki na bayanai samu. Bisa ga bayyanar da juyin halitta, ya zama ruwan dare tsoho, da haihuwa da kuma sabon ɓawon burodi. A lokacin juyin halitta daga cikin dabbobi masu shayarwa neocortex raya musamman da sauri. Ancient haushi a cikin abun da ke ciki yana da olfactory kwararan fitila da kuma yankuna, da olfactory tubercles. A tsarin da tsohon ɓangare na cingulate gyrus, amygdala da hippocampal gyrus. Sauran wuri nasa ne da neocortex.

A jijiya Kwayoyin na cerebral bawo ana shirya a yadudduka da ma'ana iri, a cikin tsarin kafa shida yadudduka:

1st - kira kwayoyin, kafa plexus jijiya zaruruwa da kuma dauke da wani m yawan jijiya Kwayoyin.

2nd - kira m grainy. Ya kunshi kananan neurons na daban-daban siffofi, kama da hatsi.

Uku - da aka hada da pyramidal neurons.

4th - ciki granular, kamar matsanancin Layer, kunshi kananan neurons.

5th - ƙunshi Betz sel (giant pyramidal Kwayoyin). Matakai na wadannan Kwayoyin (axons) samar da pyramidal fili, wanda ya kai caudal rabo kuma wuce a gaban Tushen daga cikin laka.

6th - multiforme kunshi neurons triangular kuma fusiform.

Ko da yake na tsarin jijiya kungiyar na bawo yana da yawa da ya yi, a mafi cikakken nazari da shi nuna bambance-bambance da ya bayyana a cikin zaruruwa, da size da kuma yawan Kwayoyin da su sashe detritus. By karatu mutum kwakwalwa bawo taswirar da aka shirya, wanda ya hada da yankuna 11 da kuma 52 daga cikin filin.

Ni alhakin abin da forebrain?

Sau da yawa sosai da haihuwa da kuma mazan haushi a hade. Su samar da olfactory kwakwalwa. A forebrain ma alhakin nastorazhivanie da hankali, ke taka rawa a cikin autonomic halayen. A tsarin daukan bangare a cikin samuwar Ilhamin hali da kuma motsin zuciyarmu.
