Abstract

Ultrastructural studies of taste organs in tadpoles of Bombina variegata indicate that these are taste buds (TBs). They occur in the apical parts of papillae of the mouth cavity lining. Each taste bud consists of taste cells and supporting cells; no basal cells were found. In the sensory area of taste bud there are two types of sensory cells: cells with a tuft of short (approximately 1.5 m) microvilli and cells with a single, longer (up to 3.7 microns) process, definitely longer than in TBs of other studied species of Anura. Fairly often, twin TBs were observed.

摘要

对东方铃蟾蝌蚪味觉器官的超微结构研究表明,这些是味蕾(TBs)。它们出现在口腔内衬乳头的顶端部分。每个味蕾由味觉细胞和支持细胞组成;未发现基底细胞。在味蕾的感觉区域有两种感觉细胞:一种是带有一束短(约1.5微米)微绒毛的细胞,另一种是带有单个较长(长达3.7微米)突起的细胞,肯定比其他已研究的无尾目物种的味蕾中的突起更长。相当常见的是,观察到成对的味蕾。
