摘　　要：目的对人下肢腓肠肌进行亚部化再研究,为深入探讨腓肠肌各部分的功能提供形态学依据。方法①大体解剖法解剖成人尸体20具,观察和记录腓肠肌肌纤维起止、排列形式。②Sihler’s肌内神经染色法用尸体5具,取腓肠肌做肌内神经染色,观察肌内神经分支分布特征。结果①大体解剖研究:腓肠肌外侧头可分为肌质亚部、外侧浅亚部和外侧深亚部三个肌亚部,腓肠肌内侧头无区分肌亚部的形态特征。②Sihler’s肌内神经染色法:腓肠肌外侧头神经入肌后分出5支,分别支配三个亚部,呈多支型分布;腓肠肌内侧头肌内神经呈单支主干型分布。结论根据肌形态和肌内神经分支分布特征腓肠肌外侧头可分出三个肌亚部,腓肠肌内侧头不具有划分亚部的特征。Objective To provide a detailed morphologie data for further studying deuto-parts of human gastrocnemius. Methods ①Samples of gastrocnemiuses （n=40） were obtained from 20 human cadavers（25-45a）. To observe and record the arrangement style of muscle fibers ② Sihler＇ s staining technique was used to observe the nerve branch patterns of 5 sides adult samples （20a,45a）. Results ①Anatomical evidence suggested that the human LG was clearly organized into three compartments by architecture. It was impossible to distinguish human MG compartments based upon architecture.②There were 5 main nerve branches demonstrating three deuto-parts of human gastrocnemius. Each distinct architectural compartments that were not innervated by private branch from the main muscle nerves. The MG has one main nerve trunks that branched into 4 secondary branches. Conclusions The LG has three architectural compartments. The MG have not muscular compartment based on both architecture and innervation pattern.
