人体小腿中有两块并列的骨,这就是胫骨和腓骨。它们长短似乎一样,不易区别。有人说,从其粗细来分别,即一块粗的是胫骨,另一块细的是腓骨。看看教材里的插图,对照教学挂图和模型,认为上述说法是有道理的,几年前,我也是这样教给学生的,但课后调查。真正能区别两骨的只有一半。通过近几年的教学实践,我发现一种区别胫骨和腓骨的新方法:位于小脚趾一侧的是胫骨,位于另一侧的是腓骨。 There are two juxtaposed bones in the human shank. This is the tibia and tibia. Their length seems to be the same and it is not easy to distinguish. Some people say that from their thickness, one thick bone is the cheekbone and the other one is the cheekbones. Looking at the illustrations in the teaching materials and comparing the teaching charts and models, I believe that the above statement makes sense. A few years ago, I also taught students like this, but after class investigation. Only half of the two bones can really be distinguished. Through the teaching practice in recent years, I have discovered a new method of distinguishing the sacrum from the sacrum: the sacrum on one side of the little toe and the sacrum on the other.
