Kuti imagwiritsidwa forebrain ndi zimene amatha kuchita izo amachita

The forebrain ndiyo rostral nthambi ya ubongo. Amakhala wa hemispheres oziziritsa (a kotekisi) ndi ganglia woyambira. Yotsirizira, pokhala kotekisi ndi, inali pakati pa mbali mazunzo a ubongo ndi diencephalon. The zikuchokera nyumba izi nyukiliya zikuphatikizapo caudate phata, nkhono, amene pamodzi zimapanga corpus striatum. Dzinali kuti walandira chifukwa cha kusinthana kwa nkhani imvi lopangidwa ndi maselo mitsempha, ndi woyera. zinthu izi, pamodzi ndi oziziritsa wotumbululuka mpira, wotchedwa pallidum mawonekedwe striopallidarnoy dongosolo. dongosolo mu nyama, kuphatikizapo anthu, ndi chipangizo zikuluzikulu nyukiliya ndi zochitika pa njira ya khalidwe galimoto ndi ntchito zina zofunika.

The zikuchokera kwa ganglia woyambira ndi subcortical mtima ndi yosiyanasiyana zikuchokera ma. The globus pallidus ali yaikuluikulu manyuroni. Striatum foni ali ndi gulu ofanana. Pakuti manyuroni striopallidarnoy machitidwe kupita zikhumbo ku kotekisi oziziritsa, thalamus, mapulaniwo mtima.

Kodi ntchito subcortical mtima wotani?

Zokhala striopallidarnoy kachitidwe nawo mgwirizano galimoto ndi ntchito galimoto. Kukondoweza kwa caudate phata, akutembenukira mitu khalidwe stereotypical ndi kugwedeza kayendedwe ka mikono kapena forelimbs nyama. Mu ndondomeko ya kuphunzira striatum, iwo anapezeka kuti ali ndi udindo mu njira pamtima kayendedwe. Kuyabwa nyumba imeneyi akuphwanya njira yokumbukira ndi kuphunzira. dongosolo Striopallidarnoy ochitachita zotsatira ochepetsera ntchito locomotor ndi zigawo zake maganizo, monga zimene aukali.

Khungwa la hemispheres oziziritsa

The forebrain maphunziro, ndilo lotchedwa kutumphuka. Amaona mapangidwe wamng'ono ubongo. Morphologically, kotekisi wa wapangidwa ndi imvi nkhani okuta ubongo lonse ndipo ali ndi lalikulu chifukwa makola ambiri ndi convolutions. Nkhani imvi imakhala nambala yaikulu maselo mitsempha. Chifukwa ili chiwerengero cha kugwirizana synaptic ioneka lili yosungirako ndiponso pokonza mfundo analandira. Pamaziko a maonekedwe ndi kusanduka, akutali wakale, akale ndi atsopano kutumphuka. Pa zamoyo wa neocortex zolengedwa zoyamwitsa anayamba makamaka mofulumira. makungwa Wakale kapangidwe kake ali ndi mababu olfactory ndi timapepala timabamputi olfactory. Kapangidwe ka gawo lakale la cingulate gyrus, amygdala ndi gyrus hippocampal. M'dera otsala limabweretsa neocortex lapansi.

maselo mitsempha ya kotekisi oziziritsa imakonzedwa mu zigawo ndi mwadongosolo, mu dongosolo pachilengedwe zigawo zisanu ndi chimodzi:

1 - otchedwa maselo, anapanga plexus mitsempha ulusi ndipo ali mlingo wa maselo mitsempha.

2 - wotchedwa wakunja grainy. Amakhala manyuroni ka akalumikidzidwa osiyana, ofanana mbewu.

Chachitatu - wapangidwa ndi manyuroni pyramidal.

4 - mkati granular, ngati wosanjikiza lakunja tichipeza manyuroni yaing'ono.

5 - lili ndi maselo Betz (maselo chimphona pyramidal). Njira ya maselo amenewa (axons) kupanga thirakiti pyramidal imene imafikira magawo caudal napereka ku mizu kutsogolo kwa chingwe msana.

6 - multiforme tichipeza manyuroni triangular ndi fusiform.

Ngakhale bungwe ubongo wa kotekisi ali kwambiri kuchita, ndi kuphunzira zambiri zinasonyeza kusiyana amene amapezeka ulusi, kukula ndi nambala ya maselo detritus zawo nthambi. Mwa kuphunzira ubongo kotekisi mapu unakonzedwa, womwenso zigawo 11 52 za kuthengo.

Ndili ndi udindo forebrain chiyani?

Nthawi zambiri akale ndi akulu makungwa pamodzi. Iwo apanga ubongo olfactory. The forebrain ndi udindo nastorazhivanie kwambiri, mtsikanayu zochita autonomic. Kachitidwe watenga mbali mu mapangidwe amachita mwachibadwa ndi maganizo. Mu zatsopano nyama, pamene mkwiyo makungwa zaka kuoneka zotsatira kugwirizana ndi kachitidwe m'mimba: kutafuna, kumeza peristalsis. Komanso chomveka kwa tonsils amachititsa kusintha ntchito ya ziwalo (impso, chiberekero, chikhodzodzo). Madera ena a kotekisi akugwira nawo m'kati kuloweza.

Pamodzi ndi ubongo imene imalamulira kutentha, m'dera limbic ndi forebrain (makungwa wakale ndi akale) kupanga dongosolo limbic, amene amakhala homeostasis ndipo amaonetsetsa kuteteza mitundu.
