Muscle cells of 25 humans fetuses 7, 9, 10, 14, 17, 20, and 24 weeks old were examined by electron microscopy to determine the structural characteristics of developing muscle. Three structurally different levels of maturation of muscle cells, the primitive myotube, the mature myotube, and the immature muscle fibers, have been observed in the process of human ontogenesis. The sequence of morphological changes and the timing of transformation of one form of fetal muscle into a more mature form are presented.
对25例7、9、10、14、17、20和24周龄人类胎儿的肌肉细胞进行电子显微镜检查,以确定发育中肌肉的结构特征。在人类个体发育过程中,观察到肌肉细胞成熟的三个结构不同水平,即原始肌管、成熟肌管和未成熟肌纤维。本文呈现了形态学变化的顺序以及一种胎儿肌肉形式转变为更成熟形式的时间。
