The structures of the rostral palate in regard to the vomeronasal complex of different species of mammals were studied. In all cases, we find a very interesting system of furrows which preserves a connection between the nasopalatine ducts and the preoral surroundings. For rodents, lagomorphs, Solenodon, Setifer, and Echinops, we find a special situation in this part of the palate. Here the incisors are not separated by a diastema nor the oral openings of the nasopalatine ducts are overgrown by a bipartite caudal branch of the rhinarium. The results of the anatomic studies of the vomeronasal complex and the rostral palate of the mammals investigated are discussed: First of all, some elements of the vomeronasal complex needed to be analysed in regard to structure and nomenclature, specifically the cartilago paraseptalis with its outer bar, the cartilago ductus nasopalatini and the cartilago palatina. Because of 2 criterions, the vomeronasal complex could be classified as either primitive or progressive. We find a primitive one in Didelphis, Tupaia, Solenodon, Oryctolagus, and all rodents. In contrast, the other insectivores studied and all primates show progressive structures at their vomeronasal complex. Finally, conclusions in regard to the function of the organs of Jacobson are derived from these studies. The significance of the "flehmen" mechanism for the functioning of the organs is questioned.
研究了不同种类哺乳动物吻部腭部相对于犁鼻器复合体的结构。在所有情况下，我们都发现了一个非常有趣的沟系，该沟系保持了鼻腭管与口前周围环境之间的联系。对于啮齿动物、兔形目动物、沟齿鼩、针鼹和刺猬，我们在腭部的这一部分发现了一种特殊情况。在这里，门齿没有被齿隙隔开，鼻腭管的口腔开口也没有被鼻镜的二分尾支覆盖。讨论了所研究哺乳动物犁鼻器复合体和吻部腭部的解剖学研究结果：首先，需要对犁鼻器复合体的一些结构和命名元素进行分析，特别是带有外侧杆的鼻中隔软骨、鼻腭管软骨和腭软骨。基于两个标准，犁鼻器复合体可分为原始型或进化型。我们在负鼠、树鼩、沟齿鼩、穴兔和所有啮齿动物中发现了原始型。相比之下，所研究的其他食虫动物和所有灵长类动物的犁鼻器复合体显示出进化结构。最后，从这些研究中得出了关于雅各布森器官功能的结论。对“裂唇嗅”机制对这些器官功能的意义提出了质疑。
