肌梭的结构和功能

Structure and Function of muscle spindle

肌梭是存在于骨骼肌内的一种本体感受器,其结构和功能十分复杂。本文从肌梭的分布特点和形态结构,梭内肌纤维的分类及神经支配,以及肌梭在发动牵张反射、参与形成本体感觉、调制伤害性传入中的作用等几个方面,对肌梭研究的新进展进行了综述。

Muscle spindle is a proprioceptor in the skeletal muscle.Its structure and function are very complicated.The distributing and structure of muscle spindle;the classification and innervation of intrafusal fibers;and the function of muscle spindle in stretch reflex,proprioception and analgesia are re- viewed.
