Xuduntii asalka Cerebral.

Under jilif ee maskaxda ku yaal group midka gaar ah ee dhismayaasha aadeen - ganglia ee asalka (ganglia). Wada jir ah ula dhexdhexaad kale nuclei iyo diencephalon ay saamayn ku yeelato hawl motor, taas oo uu leeyahay shaqo kale oo aan ahayn cerebellum ah. Farqiga u dhexeeya waa in nuclei asalka ah ee barka maskaxda ku jira ma aqbasho toos ah kiliyaha cerebral. Ganglia saamayn kiliyaha motor of maskaxda ku lug leh hawlaha fahanka iyo dareenka ah.

ganglia Basal weyn u saameeya kiliyaha cerebral. Ay cillad keenaysaa in carqalad ah dhaqdhaqaaqa. disorder waa ay sabab u tahay door muhiim ah in nidaamka lateral of dhaqdhaqaaqiisa. Haddii ganglia ee asalka ah ee barka ah ee maskaxda loo bandhigi cudurka, calaamadaha soo socda: daciif ah muruq iyo qaab isutaag. xuduntii Basal jilciso dhaqdhaqaaqa dhaca inta lagu guda jiro "bilowdo-up" ah kiliyaha cerebral, iyo sidoo kale la xakameeyo dhaqdhaqaaqa la rabin. qiyaas la hago helay isku midka ah. Laga bilaabo meelaha aad kaliga, goobaha dareenka iyo motor degaaankaaga, iyo sidoo kale deegaanka taajkii, macbudyo, qoorta.

xuduntii asalka Cerebral ka kooban striatum ah, oo ay ku jiraan amygdala, deedka, lenticular iyo xuduntii caudate.

- jirka Mindaleobraznoe ku taalaa gobolka temporal. In zone this, qolof ah xoogaa awgii;

- xayndaabka dibadda waa ka asaasiga ah (lens-qaabeeya). Waxay leedahay qaab dhumucdiisuna saxan of laba milimitir ah. Qaybta hore waa awgii. On ku laayeen lateral of ferjiga ku caan arrinta cawlan. xayndaabka xadka feedhaha siman,

- xuduntii lenticular waxa uu ku yaalaa dibadda ha ka caudate ah. Kooxaaha yar oo ah arrin cad waxaa loo qaybiyaa saddex qaybood oo muhiimka ah.

- xuduntii caudate waxaa ku lug leh dhismaha geeska sare ee derbiga ventricle lateral.

The ganglia asalka aadan haysan waddo toos ah laf dhabarta. From striatum ee gobolka nigra substantia ah mesh iyo kubad cirro dillaac fudud diyaarin inhibitory fiiloyin (GABAergic). Ay orientation functional ku salaysan saamaynta sii kordhaysa ee excitation ee nuclei thalamic qaybo ka mid ah kiliyaha motor ayaa mas'uul ka ah dhaqdhaqaaqa lagama maarmaan.

Ururka hab aan toos ahayn waa arrin adag. Geedi socodka ka kooban yahay in xakamaynayaan excitation ee thalamus si kiliyaha motor zone kale. Qaybta koowaad waxaa ku jejebiyey track ka kooban GABAergic qiyaas striatal in pallidus ku globus lateral. jejebiyey Last in xuduntii of thalamus soo diro macdantaa. core xiiso saarka fiiloyin ka buuxsamay. Qaar ka mid ah u soo diray inuu kubada cirro lateral. The fiiloyin haray gudbaan aagga reticular of nigra substantia ah, oo ka howgala dillaac fudud cirro. Laga soo bilaabo tan u socota in haddii saamaynta kaakicin jidka tooska ah ee striatum u kordhiyaa dhaqdhaqaaqa ee excitatory of kiliyaha motor ah, waxqabad ee dariiqa aan toos ahayn u jilciyaa.

Cillad ah nuclei subcortical keenaysaa in cudurka of motor kartidooda. Waxay noqon mid xad-dhaaf ah ama maqan dhammaantiis. Tusaale ahaan, waxay keeni waa in cudurka Parkinson. Dadka la kulantay cudurka sida, heli fool-maaskaro. Socodka waxaa loo sameeyaa in tallaabooyin yaryar. Man waa adag tahay si ay u bilaabaan oo ay joojiyaan mooshinka. Waxaa gariiraya (gariirka) addimada, kor u cabirida xaalada muruqa. Waxaa jira cudurka Parkinson sabab u tabinta ee falalkooda dareemaha si xadgudub ah ee striatum walax. guuldaradii of striatum ku keenaysaa in dhaqdhaqaaqyo aan loo baahnayn: gariir qoorta iyo wejiga muruqyada, jir, gacmaha, lugaha. Waxaa sidoo kale laga yaabaa in hawl korodhka qaab dhaqdhaqaaqa oo isug ee jirka.

Gebogebadii, waa in la ogaadaa xidhiidh toos ah ee nolosha ee kartida hawlaha caadiga ah ee maskaxda aadanaha. weecasho ugu yar ee maskaxda ku keenaysaa in cudurro kala duwan, naafada, iyo mararka qaar in ay total curyaannimo. Sidaa darteed, dhaawaca waa in laga fogaadaa, ma aha in aad soo bandhigaan si khatarta aan loo baahnayn in halis loo baahnayn.
