Lo mba izimvi ingqondo kunye umnqonqo into gray

Inkqubo luvo lo umnqonqo kunye nobuchopho. into nobuchopho iyunifomu layo ekwakhiweni, nesithomo sakhe into emhlophe hina. White phezulu luvo, iinkqubo zazo, ukuba, ngokulandelelana, umbala omhlophe. Grey - Sisihloko iiseli zemithambo-luvo kunye neenkqubo ezi seli.

Kuye kwasekwa iqela elikhulu kakhulu iintlobo ezintathu zemithambo-luvo, neyohlulwe ezingundoqo: iiseli radicular umqadi luvo iiseli ngaphakathi. Ibekwe ngaphakathi yaye singqongwe into emhlophe. Siqulunqwa ngakumbi kwi wesibeleko kunye empontshwa yomqolo, nto leyo lu dityanisiwe ukwanda luvo motor.

Xa iziko kukho ijelo engundoqo ehamba yonke ubude umnqonqo, kwaye usekelwe kuyo. Equlethwe esemseleni cerebrospinal fluid. Oku singqongwe mba ongwevu, leyo kuthiwa intermediate. Apha, lo mbandela ezingwevu lungohlulwa lube phambi ngamawele, kwicala nangesemva ngezibini columns. Ngokunjalo, cross-kwicandelo iimpondo ezintathu: ngaphambili, kwicala nangesemva.

umnqonqo udlula ngaphandle naluphi na utshintsho Oblongata Medulla. Umda oluthi luqokelelane phakathi evuthelweyo kunye ngasemva, yindawo apho zifumaneka iingcambu kwisibini sokuqala luvo lwe umnqonqo. Amasebe inxalenye ephezulu liyajiya emazantsi. Engqondweni, i core evuthelweyo zinoxanduva sokulinganisela, ulungelelwaniso, ukutya, igazi kunye nokuphefumla. Gland ziquka iindawo ezimbini: ibhulorho kunye kwiCerebellum.

Bridge - roller emhlophe ibekwe yi isiseko ingqondo. Front ungabona umda kunye imilenze ingqondo, kwaye ngasemva - ukuya Oblongata Medulla. Icandelo cross zibonwa umcimbi emhlophe kunye kwahlelwa gray. Ukuqhubeka Medulla na inxalenye amanakani okuba le bhulorho, apho zicwangciswe iinkqubo isivamvo engundoqo kunye luvo cranial. Apha esilawulwa umcimbi izimvi ebuchotsheni. KwiCerebellum ibekwe phantsi emva ingqondo. Luquka zifaka kunye nenxalenye eliphakathi - worm. Impethu lebhokisi zifaka ezimbini. maleko Cerebellum ihlanganisa mbandela izimvi le ngumonzakalo kwiCerebellum fomu ijikajike. Le into emhlophe lihlaba gyrus. Ngaphezu kele zabo umcimbi izimvi ebuchotsheni. Picture-in candelo efana kakhulu emthini.

Phakathi mbandela izimvi eziba ezibaluleke kakhulu kwaye uninzi okuphawulekayo elakha ebomvu eyenza into eza kuqala. Plumbing ubuchopho - ijelo elimxinwa kunye ubude ngeesentimitha ezimbini. Idibanisa i ventricles, kwesesithathu nakwesesine isizukulwana. Le channel ezingqonge umba izimvi lobuchopho, nto leyo engundoqo nezenziwe zeeseli ezincinane. Le Ingqondo eliphakathi mba iqulathe nuclei akwi kumaziko ebekwe phantsi uqweqwe, kwaye linoxanduva zonke iintlobo uvakalelo. Telencephalon, kuba iqulathe iinxalenye ezimbini, i zifaka ezimbini. Le neuron zobuchopho umcimbi ezingwevu ngohlobo imbasa. Oku akhiwa iiseli zemithambo ngamanani amakhulu. Ezi seli lungahlulwa-hlulwa zibe zikhabane. umaleko nganye, nayo iye iimpawu ezithile azalwa kuyo.

Ngenxa yoko, ndaba ezingwevu - le isikhungu luvo kunye luvo. Ukuxinana kwenzeka kwinkqubo luvo, nto leyo ibe umnqonqo nobuchopho. Le nto yenza neuron kunye nuclei subcortical. Kweziyobisi umnqonqo ukhandwa iiseli zemithambo-luvo, apho kukho malunga nezigidi ezilishumi. Umthamo mba ezingwevu eziqulethwe ingqondo uyakwazi ukuphembelela inqanaba lophuhliso ngokwengqondo. Kulindeleke processing ukuba isixa esongezelelweyo zenkqunto ezingwevu kakhulu ngokukhawuleza yolwazi.
