In the human intraorganic nerves of the thoracic muscles amyelin fibers make 62% and myelin ones--38%. In transversal sections ultrastructure of the myelin and amyelin fibers varying in their diameters has been studied. In the myelin and amyelin fibers the amount of various organells is not equal: in the amyelin fibers the arrangement density of microtubules is greater than that of neurofilaments, there is a reverse dependence between the amount of the microtubules and the neurofilaments on the one hand, and the fibrilar diameter, on the other hand. In the myelin fibers with the increasing diameter, the amount of the neurofilaments increases, while that of the microtubules decreases.
在胸肌的人体器官内神经中，无髓纤维占62%，有髓纤维占38%。已对横切面上不同直径的有髓和无髓纤维的超微结构进行了研究。在有髓和无髓纤维中，各种细胞器的数量并不相等：在无髓纤维中，微管的排列密度大于神经丝，微管和神经丝的数量一方面与纤维直径另一方面呈反向依赖关系。在有髓纤维中，随着直径增加，神经丝数量增加，而微管数量减少。
