The general structure of the enteric nervous system in the omasum of sheep was investigated by immunohistochemical techniques using antineurofilament protein antibody. The myenteric plexus consisted of polygonal ganglia and interganglionic nerve bundles. The meshwork of the plexus in the oral region was denser than the middle and aboral regions. Intraganglionic laminar endings were present in the myenteric ganglia. The submucosal plexus was divided into sublaminar and intralaminar plexuses. The latter was denser near the free border of the omasal laminae than in the region near the omasal wall. There were no ganglion cells showing neurofilament protein-like immunoreactivity in the submucosal and mucosal layers. Probable mucosal receptors were found in the horny omasal papillae near the reticulo-omasal orifice. The findings demonstrate a complicated structure for the enteric nervous system in the omasum, presumably reflecting its regulatory activities.
采用抗神经丝蛋白抗体的免疫组织化学技术，研究了绵羊瓣胃中肠神经系统的总体结构。肌间神经丛由多边形神经节和神经节间神经束组成。神经丛在口侧区域的网络比中间和肛侧区域更密集。肌间神经节内存在神经节内板层终末。黏膜下神经丛分为板层下神经丛和板层内神经丛。后者在瓣胃叶片游离缘附近比在靠近瓣胃壁的区域更密集。在黏膜下层和黏膜层中未发现显示神经丝蛋白样免疫反应性的神经节细胞。在瘤网口附近的角质化瓣胃乳头中发现了可能的黏膜受体。这些发现表明瓣胃中肠神经系统结构复杂，推测这反映了其调节活动。
