快肌与慢肌失神经支配后的形态学变化
Morphological changes of denervated fast-twitch and slow-twitch muscles
摘要
Abstract
Objective:To investigate the morphological differences between fast-twitch muscles(tibialis anterior)and slow-twitch muscles(soleus)during denervation.Methods:The rat sciatic nerve disconnection model was established,and the morphological changes of the tibialis anterior and soleus muscles during denervation were analyzed by histopathological techniques.Results:After sciatic nerve injury,soleus atrophy was more severe compared to tibialis anterior muscle,as evidenced by smaller wet weight,lower cross-sectional area ratio of muscle fiber,less complete ultrastructure and more serious damage of motor endplate.Conclusion:The atrophy of slow-twitch muscle is more severe than fast-twitch muscle after denervation.关键词
