摘　　要：目的：研究人股直肌肌构筑特征，肌梭的分布部位、范围及密度，进一步探讨股直肌的亚部划分，为临床外科提供肌形态学资料。方法：用大体解剖法观察20具尸体股直肌的肌构筑学特征；用组织学H—E染色法研究5具尸体股直肌肌梭分布。结果：股直肌是由短肌纤维和肌内腱板构成的羽肌，肌质量（158．7±10．5）g，肌长（30．2±2．0）cm，肌纤维长（6．7±1．8）cm，羽状角17．1°±2．3°，肌节长（2．03±0．07）cm，生理横切面积（22．38±3．10）cm^2；股直肌肌梭平均密度为19．38个／克。结论：股直肌的上部比其中、下部肌梭密度高；根据股直肌的肌构筑特征结合肌内神经分支分布，进一步证实股直肌可分为外上和内下两个亚部，可考虑进行亚部化取材用于肌移植。Objective： To provide a morphologic basis for clinical application by determining the muscle architecture and muscle spindle, and the pattern of intramuscular nerve branch within rectus femoris （RF）. Methods： Architectural feature of RF was studied by using the gross-anatomy from 20 human adult cadavers; H-E staining technique and stereology method were used to study the muscle spindle distribution of 5 adult cadavers. Results： RF was a kind of penniform muscle which was composed of short fascicle and an intramuscular tendon board. The average muscle mass, muscle length, fiber length, pinnate angle, sarcomere and cross sectional area of RF were （158.7±10. 5）g, （30. 2±2.0）cm, （6.7±1.8）cm, （17. 1±2. 3）°, （2. 03±0.07）cm and （22.38±3. 1）cm^2 , respectively. The muscle spindle average density of RF was 19.38 number/g. Conclusion ： The muscle spindle density of superior portion in RF is higher than that of middle and inferior portion; RF could be divided further into the lateral superior and medial inferior compartments. The lateral superior and medial inferior compartments of RF could be used for muscle transplantation solely.
