The tongues of three fishes were investigated histochemically to determine the distribution and nature of mucosubstances by employing recent techniques and the results were considered comparatively with the lingual mucosubstances of other vertebrates. A heterogenous distribution of neutral mucosubstances, sulfomucins and sialomucins in various lingual sites was noted. The taste buds and/or free nerve endings were found to be restricted in the areas containing abundance of goblet cells. In non-gustatory areas of tongue, the goblet cells were very few or absent. Importance of lingual histology in establishing phylogenetic relationships and the possible functional significance of the mucosubstances in the physiology of gustation is discussed in detail.
采用最新技术对三种鱼类的舌头进行了组织化学研究,以确定黏液物质的分布和性质,并将结果与其他脊椎动物的舌部黏液物质进行了比较。在舌部不同部位发现了中性黏液物质、硫黏液和涎黏液的异质性分布。味蕾和/或游离神经末梢局限于杯状细胞丰富的区域。在舌的非味觉区域,杯状细胞很少或不存在。详细讨论了舌组织学在建立系统发育关系中的重要性以及黏液物质在味觉生理中的可能功能意义。
