腱感受器(Tendon Receptor)的汉英词典释义与详解
中文释义:
腱感受器是分布于肌腱与肌肉连接处的本体感受器,主要功能是感知肌肉收缩或被动拉伸时产生的张力变化。其核心结构为高尔基腱器官(Golgi Tendon Organ, GTO),呈梭形包裹于胶原纤维束内。当肌肉张力升高时,胶原纤维挤压腱器官内的神经末梢,触发抑制性信号传入脊髓,防止肌肉过度收缩导致的损伤,这一机制称为“反牵张反射”。
英文释义:
Atendon receptor is a type ofproprioceptor located at the musculotendinous junction, primarily responsible for detectingchanges in tension during muscle contraction or passive stretching. Its key structure, theGolgi Tendon Organ (GTO), consists of encapsulated nerve endings intertwined with collagen fibers. Increased muscle tension deforms the collagen, activating the receptor to sendinhibitory signals to the spinal cord, thereby modulating muscle force and preventing injury via the"inverse myotatic reflex".

腱感受器通常指腱器官(Golgi tendon organ),是存在于肌腱中的一种本体感受器,主要感知肌肉张力的变化。以下是详细解释:
腱感受器(腱器官)是调控肌肉张力的关键结构,通过动态反馈维持运动稳定性和保护组织。需注意其与肌梭的功能差异及协同机制,以理解运动控制的全貌。
