The soft-tissue components of the vomeronasal organ of the pig, the cow and the horse were studied with the aid of dissection, microdissection, and light microscopy and immunohistochemistry of series of transverse sections. In horses, the rostral end of the incisive duct was blind: thus, unlike in pigs and cows, there was no communication between the vomeronasal organ and the oral cavity. In all three species, the central part of the vomeronasal duct bore the 'typical' respiratory/ receptor epithelium lining on its lateral and medical walls. The rostral part of the duct was characterized by stratified columnar epithelium, while more caudal parts bore simple columnar type. The patterns of distribution of glands, blood vessels and nerves were closely associated with the patterns of distribution of duct linings. The distribution of soft-tissue components in pigs was less clearly defined than in cows and horses. Of the three species, nerves were detected in the rostral half of the vomeronasal parenchyma only in the horse.
借助解剖、显微解剖以及对一系列横切片的光学显微镜检查和免疫组织化学方法，对猪、牛和马的犁鼻器软组织成分进行了研究。在马中，切牙管的前端是盲端：因此，与猪和牛不同，犁鼻器与口腔之间没有连通。在所有这三个物种中，犁鼻管的中央部分在其外侧壁和内侧壁上有“典型的”呼吸/感受器上皮衬里。管道的前端部分以复层柱状上皮为特征，而更靠后的部分则是单层柱状类型。腺体、血管和神经的分布模式与管道衬里的分布模式密切相关。猪的软组织成分分布不如牛和马那样明确。在这三个物种中，仅在马的犁鼻实质前半部分检测到神经。
