摘　　要：目的　明确背阔肌的解剖分区及各区在肩关节运动中的肌电表现。方法　对 10具成人尸体背阔肌进行血管、神经解剖并按主要血管、神经的分支、分布将背阔肌分区。利用体表电极记录 13例 (2 5侧 )健康成人背阔肌不同区在肩关节运动中的肌电表现 ,并将记录结果进行统计学处理、分析。结果　背阔肌的主要血管、神经来自胸背血管、神经及其内、外侧分支 ,部分来自肋间血管、神经 ,胸背血管、神经分支及肋间血管、神经分支间有广泛的吻合 ,胸背血管、神经内、外侧支及其延长线将背阔肌分成三个区域。三区在肩关节 6种运动中的肌电表现不同。结论　背阔肌内不同区域肌纤维在肩关节运动中的作用不同。Objective\ To evaluate the anatomical division within latissimus dorsi and its elecromyographic change as shoulder articulation movement . Methods\ Using anatomical observation, projection of trophic vessel and nerve of latissimus dorsi was marked in the surface of skin. Electromyographic assessment of different area of latissimus dorsi was measured. Results\ The latissimus dorsi was mainly supplied by thoracodorsal and its interior and external branches. The latissimus dorsi can be divided three area based on these anatomical result. Electromyographic amplitude in the three areas of muscle are different. Conclusion\ Lastissimus dorsi can be divided into three areas by thoracodorsal vessel and nerve . The third area fibres were utilized preferentially when subjects performed six kinds of movements of the shoulder joint.\;
