摘　　要：目的通过对阔筋膜张肌构筑学和肌内神经分支分布的研究,为阔筋膜张肌的临床应用提供解剖学资料。方法大体解剖法、肌构筑法、改良Sihler′s肌内神经染色法。结果(1)阔筋膜张肌肌重(46.25±4.8)g,肌长(16.42±0.6)cm,肌纤维长(4.54±0.5)cm,羽状角0°,肌生理横切面积(9.65±0.74)cm2;(2)支配阔筋膜张肌的神经来自臀上神经下支,从肌的后上部入肌,入肌后向肌下部走行,分成前后两大支,前支主要支配肌前半部,后支主要支配肌后半部。结论 (1)阔筋膜张肌是扁肌,倾向于速度型构筑特征;(2)阔筋膜张肌肌内神经主要分布在肌中部。Objective In this study,the relationship between muscular architecture and distribution of intramuscular nerves of tensor fasciae latae in human was investigated.Methods Muscle architecture skill and modified Sihler′s staining were used in this study.Results Measurement results of gross anatomy were：（1）Muscle weight was（46.25±4.8）g,muscle fiber length was（4.54±0.5）cm,and physiologic cross sectional area was（9.65±0.74）cm2;（2）Intramuscular nerves of tensor fasciae latae divided into 2 main trunks in human,anterior and posterior trunks.Conclusion Tensor fasciae latae is flat muscle in human,and tends to build a speed-type architectural feature;The nerve innervating is mainly located in the middle portions of the muscle.
