【摘要】 为探求较理想的肌桥,对犬的肌条内肌纤维走向及相对长度进行了观察。结果发现,缝匠肌的肌条内肌纤维与肌长轴平行且多与肌条等长;指浅屈肌肌条内的肌纤维走向与肌条长轴夹角较大且不与肌条等长;桡侧伸腕肌肌条内的肌纤维走向与肌条长轴夹角较小但只有少量肌纤维与肌条等长。为此,笔者认为仅将外观为长条形的肌肉沿其长轴纵向切取肌桥是不够的。必须考虑到肌桥内肌纤维的走向和相对长度及其可能产生的影响,并由此提出缝匠肌可能是一较理想的肌桥。更多还原

【Abstract】 In order to find a sort of ideal muscular bridge.we observed the direction and relative length of muscular fiber in the muscular bridge from the sartorius .flexor digitorum superficialis and extensor carpi radialis of dogs by dissection under the stereoscope and image-analysis methods. The results are as follows; The most of muscle fiber in sartorius parallel the longitudinal axis of muscular bridge>and equal the muscular bridge in length. The others in our experiment are different from sartorius,although the muscular bridge is cut longitudinally along the muscle margin. So the author considers it not enough to cut off the muscular bridge longitudinally,and the more attention should be paid to the direction and relative length of muscular fibers in the muscular bridge.更多还原
