Lamellated nerve endings in the cheek mucosa of fifteen adult Sprague-Dawley rats were studied with light and electron microscopes. Serial sections revealed that the terminal axon of the lamellated nerve endings is in the central portion, and that the inner core is made up of two stacks of lamellae. These are characterized by many corpuscles located within a single papilla, which shows structural specializations at several levels. Electron microscopy showed that the corpuscles are circular in shape and that the lamellar sheets possess a rich rough endoplasmic reticulum, mitochondria and numerous glycogen-like granules. Numerous bundles of collagen fibers and an amorphous substance are located in the interlamellar spaces. The axon terminal is characterized by the presence of neurofilaments, neurotubules and mitochondria. The capsule consists of several laminae formed by cytoplasmic extensions of perineural cells presenting many caveolae, mitochondria, rough endoplasmic reticulum profiles and microfilaments.
运用光学显微镜和电子显微镜对15只成年斯普拉格-道利大鼠颊黏膜中的板层神经末梢进行了研究。连续切片显示，板层神经末梢的终末轴突位于中央部分，内核由两堆叠片组成。其特征是单个乳头内有许多小体，在几个层面上都有结构特化。电子显微镜显示，小体呈圆形，板层片含有丰富的粗面内质网、线粒体和大量糖原样颗粒。层间间隙中有许多束状胶原纤维和一种无定形物质。轴突终末的特征是存在神经丝、神经微管和线粒体。被膜由神经周细胞的细胞质延伸形成的几层薄片组成，呈现出许多小窝、线粒体、粗面内质网轮廓和微丝。
