除脑强直及除皮层均为颅内压增高失代偿阶段或急性脑病所出现的危险征象。前者尤重,常合并意识、循环及呼吸障碍,并常常迅速招致死亡。正常情况下一定区域的大脑皮层、小脑、锥体外系及脑干网状结构对肌张力的维持及运动的协调均有重要作用,脑干网状结构中有下行抑制系统及下行加强系统,下行抑制系统主要位于延髓网状结构的腹内侧区,当其兴奋时,四肢肌张力降低,这种抑制作用可为大脑皮层及小脑所加强,因此当抑
In addition to brain rigidity and cortical are intracranial hypertension increased decompensation phase or acute encephalopathy appear dangerous signs. The former is particularly prevalent, often incorporating awareness, circulatory and respiratory disorders and often rapidly leading to death. Under normal circumstances a certain region of the cerebral cortex, cerebellum, extrapyramidal and brainstem reticular structure on the maintenance of muscle tone and coordination of exercise play an important role in the brainstem network structure with downlink suppression system and downlink strengthening system, downlink Inhibition system is mainly located in the ventral medulla oblongata network structure, when the excitement, limb muscle tension decreased, this inhibition can be enhanced by the cerebral cortex and cerebellum, so when the inhibition
