摘　　要：用光镜观察了秦岭蝮Gloydius qinlingensis嗅觉系统和犁鼻系统的组织结构。结果显示秦岭蝮嗅觉系统主要包括嗅器和嗅球,犁鼻系统主要包括犁鼻器和副嗅球,并且嗅器和犁鼻器已经完全分离形成两个独立的囊,犁鼻器位于嗅器的内侧。嗅器粘膜上皮进一步分化为嗅上皮和呼吸上皮,背侧嗅上皮下的固有层内有丰富的Bowman's腺,腹侧呼吸上皮内有大量的杯状细胞,其固有层未见有Bowman's腺。鼻腔的中段出现了发达的犁鼻器,犁鼻上皮明显比嗅上皮厚,其固有层内未见有犁鼻腺,在犁鼻腔内还有蘑菇体。The microstructures of the olfactory and vomeronasal organs in Gloydius qiulingensis were examined by a light microscope. The results showed that the olfactory system mainly consists of an olfactory organ and olfactory bulb ; the vomeronasal system mainly consists of the vomeronasal organ and accessory olfactory bulb and they have separated absolutely to become two independent cysts. Vomeronasal organs are located in the interior side of the olfactory organ. In addition, olfactory organs are lined with sensory epithelium and respiratory epithelium. The Bowman＇ s glands can be found in lamina propria under the olfactory epithelium of Gloydius qinlingensis ; a large number of goblet cells exist in ventral respiratory epithelium. No Bowman＇s gland is found in its laminate propria. At the mid-nasal region, vomeronasal organ emerged and well-developed. Vomeronasal epithelium is obviously thicker than that of the olfactory epithelium. No vomeronasal gland exists in lamina propfia. The mushroom bodys emerge in the vomeronasal cavity.
