Whole-mount preparations of the porcine small intestine, consisting of the tela submucosa and the adjacent lamina muscularis mucosae, were used for scanning electron-microscopic investigation of the plexus submucosus externus (Schabadasch) after enzymatic digestion, fixation and HCI hydrolysis. The present results confirm previous light-microscopic data and provide irrefutable proof that within the submucosal plexus, considered by most authors as one ganglionated nerve plexus situated in the entirety of the tela submucosa, two distinct nerve meshworks can be distinguished, one lying close to the lamina muscularis mucosae, i.e., the plexus submucosus internus (Meissner), and the other, i.e., the plexus submucosus externus (Schabadasch), situated in the outer region of the tela submucosa against the circular smooth muscle layer. In addition to the distinct location of both plexuses, they are quite different with regard to the pattern and diameter of their nerve strands and the number and appearance of their ganglia.
猪小肠的整装标本，由黏膜下层和相邻的黏膜肌层组成，用于在酶消化、固定和盐酸水解后对外部黏膜下丛（沙巴达施）进行扫描电子显微镜研究。目前的结果证实了先前的光学显微镜数据，并提供了无可辩驳的证据，即在黏膜下丛中，大多数作者认为它是一个位于整个黏膜下层的有神经节的神经丛，可区分出两个不同的神经网络，一个靠近黏膜肌层，即内部黏膜下丛（迈斯纳），另一个，即外部黏膜下丛（沙巴达施），位于黏膜下层的外部区域，紧靠环形平滑肌层。除了这两个丛的不同位置外，它们在神经束的模式和直径以及神经节的数量和外观方面也有很大差异。
