大脑皮层、锥体外系、小脑及脑干网状结构中下行抑制系统和下行加强系统调节人体的姿势及肌肉张力。下行抑制系统兴奋时,四肢肌张力降低,大脑、小脑及锥体外系可加强下行抑制系统的作用。当网状结构下行抑制系统损害及失去与大脑、小脑、锥体外系的联系时,抑制肌张力的作用明显减弱,因而出现肢体肌张力增强。去脑强直:病变部位在中脑红核尾端水平。其
The cerebral cortex, extrapyramidal system, cerebellar and brainstem reticular structure of the downlink suppression system and the downlink strengthening system to regulate the posture and muscle tone of the human body. Downstream suppression system excitement, limb muscle tension decreased, the brain, cerebellum and extrapyramidal system can strengthen the role of downstream inhibition system. When the network down inhibit the system damage and loss of the brain, cerebellum, extrapyramidal system, the role of inhibition of muscle tone significantly weakened, resulting in muscle tone enhancement.
