摘要
目的 探讨颈神经丛深支在斜方肌运动功能中的作用。方法 采用电生理方法 ,测定切断副神经后的不同时期 ,刺激颈神经丛深支在大鼠斜方肌得到的肌电大小 ,并作统计学分析。结果 保留颈神经丛深支 ,术后不同时期 ,在大鼠斜方肌上均能测到肌电且肌电值差异有显著性。结论 颈神经丛深支是支配斜方肌的另一运动神经来源 。
Objective\ The aim of this study was to examine the effects of deep branches of cervical plexus on trapezius muscle.Methods\ The evoked electromyography of 32 trapezius of 16 SD rats was examined in different time and results obtained were processed by statistical methods.Results\ After cutting the accessory nerves, stimulating the deep branches of cervical plexus evoked the myoelectricity, the myoelectricity results varied according to different time.Conclusion\ The deep branches of cervical plexus are another important motorial supply to trapezius muscles. After cutting the accessory nerves, if the branches were undamaged, the shoulder′s function would be greatly preserved.\;
