Phylogenic outline of the vertebrate olfactory system is summarized in the present review. In the fish and the birds, the olfactory system consists only of the olfactory epithelium (OE) and the olfactory bulb (B). In the amphibians, reptiles and mammals, the olfactory system is subdivided into the main olfactory and the vomeronasal olfactory systems, and the former consists of the OE and the main olfactory bulb (MOB), while the latter the vomeronasal organ (VNO) and the accessory olfactory bulb (AOB). The subdivision of the olfactory system into the main and the vomeronasal olfactory systems may partly be induced by the difference between paraphyletic groups and monophyletic groups in the phylogeny of vertebrates.
本综述总结了脊椎动物嗅觉系统的系统发生概况。在鱼类和鸟类中，嗅觉系统仅由嗅上皮（OE）和嗅球（B）组成。在两栖动物、爬行动物和哺乳动物中，嗅觉系统可细分为主嗅觉系统和犁鼻嗅觉系统，前者由嗅上皮和主嗅球（MOB）组成，而后者由犁鼻器（VNO）和副嗅球（AOB）组成。嗅觉系统分为主嗅觉系统和犁鼻嗅觉系统，这可能部分是由脊椎动物系统发生中并系群和单系群之间的差异所导致的。
