Objective To investigate changes induced by hindlimb unloading in morphology of nerve endings in soleus muscle spindles.

目的观察后肢去负荷对大鼠比目鱼肌肌梭神经末梢形态的影响。

Results Nerve endings of muscle spindle in equatorial and polar regions were dyed black;intrafusal fibers were dyed buffy.

结果肌梭赤道部与两极部神经末梢呈棕黑色，清晰可见，梭内肌纤维染为棕黄色。

Muscle spindle is an important proprioceptor in the skeletal muscle, which contributes to the maintenance of muscular tension and the fine modulation of voluntary movements.

肌梭是骨骼肌内一种重要的本体感受器,参与肌紧张的维持和对随意运动的精细调节。
