研究了25块腕屈肌和腕伸肌的构筑特征。肌肉包括尺侧腕屈肌、桡侧腕屈肌、尺侧腕伸肌、桡侧卡普里短伸肌和桡侧腕长伸肌。肌肉长度，质量，纤维羽角，纤维长度和肌节长度（通过使用激光衍射技术）进行了测定。此外，还计算了生理横截面积和纤维长度/肌肉长度比。这些肌肉被发现是高度专业化的，相同肌肉的结构特征非常相似。肌纤维长度/肌长度比、肌长度和羽状角代表了肌肉之间的主要差异。因此，在判别分析中使用这些参数允许正确识别25块肌肉中的每一块。就大小和内在设计而言，这些肌肉的功能是高度专业化的。
The architectural features of 25 wrist flexor and extensor muscles were studied. Muscles included the flexor carpi ulnaris, the flexor carpi radialis, the extensor carpi ulnaris, the extensor capri radialis brevis, and the extensor carpi radialis longus. Muscle length, mass, fiber pennation angle, fiber length, and sarcomere length (by use of laser diffraction techniques) were determined. In addition, physiological cross-sectional area and fiber length/muscle length ratio were calculated. The muscles were found to be highly specialized, with architectural features of same muscles very similar. The fiber length/muscle length ratio, muscle length, and pennation angle represented the major differences between muscles. Thus using these parameters in discriminant analysis permitted correct identification of each of the 25 muscles. In terms of size and intrinsic design, these individual muscles were highly specialized for their function.
