腱感受器(Tendon Receptor)的漢英詞典釋義與詳解
中文釋義:
腱感受器是分布于肌腱與肌肉連接處的本體感受器,主要功能是感知肌肉收縮或被動拉伸時産生的張力變化。其核心結構為高爾基腱器官(Golgi Tendon Organ, GTO),呈梭形包裹于膠原纖維束内。當肌肉張力升高時,膠原纖維擠壓腱器官内的神經末梢,觸發抑制性信號傳入脊髓,防止肌肉過度收縮導緻的損傷,這一機制稱為“反牽張反射”。
英文釋義:
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".

權威參考文獻:
腱感受器通常指腱器官(Golgi tendon organ),是存在于肌腱中的一種本體感受器,主要感知肌肉張力的變化。以下是詳細解釋:
腱感受器(腱器官)是調控肌肉張力的關鍵結構,通過動态反饋維持運動穩定性和保護組織。需注意其與肌梭的功能差異及協同機制,以理解運動控制的全貌。
