锥体外通路是指在随意运动通路(锥体系)以外的所有自动运动通路,包括从大脑皮质到各级运动神经元的一系列结构,并是由一系列短轴突的神经元所构成,参与肌张力、姿势及自动与随意运动的调整。锥体外系与锥体系虽为人体运动通路的两个不同组成部分,但却互为补充、影响,也正是在锥体外系的密切配合的基础上,才能保证人体得以完成各种有目的的、准确的随意运动。
Extrapyramidal pathways are defined as a series of autonomic pathways beyond the voluntary path of motion (cone system), including a series of structures ranging from cerebral cortex to motoneurons at all levels and composed of a series of neurons of the short axons, Muscle tension, posture and automatic and free movement adjustment. Although the extrapyramidal and pyramidal systems are two different components of the human body’s movement pathways, they supplement and influence each other, and it is precisely on the basis of close coordination of the extrapyramidal system that the human body can accomplish various purposeful , Accurate free exercise.
