根据电子显微镜的定义，在青蛙快速骨骼肌的肌神经连接处有三个细胞层。这些细胞包括一个覆盖在终末“非突触”表面并将其与外部结缔组织分开的有核雪旺细胞，轴突终末及其聚集的线粒体和500个A-囊泡，以及具有规则的突触折叠横向排列的肌肉纤维。详细描述了这些结构和附加的相邻结构。
Three cell layers as defined by electron microscopy are described at the myoneural junction in fast skeletal muscles of the frog. These consist of a nucleated Schwann cell which covers the "non-synaptic" surface of the terminal and separates it from extraneous connective tissue, the axon terminal with its accumulation of mitochondria and 500 A-vesicles and the muscle fiber with its regular transverse array of synaptic folds. These and additional adjacent structures are described in detail.
