| 摘 要： | 目的 通过对人臀大肌肌内神经分支分布、肌梭密度的研究,提供臀大肌比较详尽的解剖学资料.方法 取成人尸体12具,大体解剖后,6具用于改良Sihler肌内神经染色,另6具行HE染色. 结果 臀大肌受臀下神经支配,有上、中、下3个分支.肌内次级分支多达11 ～ 14支,沿肌束排列方向走行.臀大肌的肌梭密度平均为(14.91±3.05)个/cm3,肌梭指数为(14.12±4.34)个/g,臀大肌下部肌梭密度最高(25.38±6.25)个/cm3、(24.03±5.92)个/g. 结论 支配臀大肌的神经肌内次级分支多,沿肌束排列方向走行；人臀大肌下部的肌梭密度明显高于肌上部和肌中部.

| Abstract: | Objective To study the distribution of intramuscular nerve branches and muscle spindles of the gluteus maximus. Methods Dissection, modified Sihler’s neural staining technique ( EM>n/EM> =6) and hematoxylin-eosin staining ( EM>n/EM> =6) were used to study the gluteus maximus from 12 cadavers. Restults The number of secondary branches of the inferior gluteal nerve were 11-14. They ran along the direction of muscle bundles. Spindle density and spindle index of human gluteus maximus were （14.91±3.05）number/cm3 and （14.12±4.34）number/g, respectively. The highest spindle density and spindle index area of gluteus maximus were in the lower part of the muscle. BR>Conclusions There are many secondary branches of the inferior gluteal nerve. They travel along the direction of muscle bundles. The highest spindle density and spindle |
