Mean sarcomere length has been determined by laser diffraction in fibres of mouse soleus muscle at various times after division of the proximal tendon. Sarcomere length was initially reduced by 27% but was normal from 7 days after tenotomy. Initial shortening was less but recovery slower if the muscle was also denervated. Sarcomere length did not recover by 14 days if the tendon was cut soon after the muscle fibres became reinnervated after nerve section. It is suggested that afferent nervous pathways are involved in the short-term adjustment of sarcomere length to fibre length.
在切断小鼠比目鱼肌近端肌腱后的不同时间，通过激光衍射法测定了肌节的平均长度。肌节长度最初缩短了27%，但在肌腱切断术后7天恢复正常。如果肌肉同时去神经支配，最初的缩短幅度较小，但恢复较慢。如果在肌肉纤维在神经切断后重新获得神经支配后不久切断肌腱，肌节长度在14天内无法恢复。这表明传入神经通路参与了肌节长度对纤维长度的短期调节。
