Abstract

It was seen in ten specimens that their plantaris muscle had different sizes of myons, whicnother were found. The number of motor units of the plantaris was counted in five subjects after transverse section of the muscle and nervous fibers of each of them. Considering the number of motor fibers as 60% in each nerve, the average value of muscle fibers per motor unit was 372, which is quit a small number. The fact led us to think that the plantaris muscle has a very refined function.

摘要

在十个标本中发现，它们的跖肌有不同大小的肌纤维，未发现其他情况。在五名受试者中，在切断他们每个人的肌肉和神经纤维后，对跖肌的运动单位数量进行了计数。考虑到每条神经中运动纤维的数量为60%，每个运动单位的肌纤维平均值为372，这是一个相当小的数字。这一事实使我们认为跖肌具有非常精细的功能。
