Abstract

Serial sections of 182 fungiform papillae, obtained at autopsy from 22 individuals aged 2 days to 90 years, were examined by light microscopy with regard to location and number of taste buds. The taste buds were always found on the convex, dorsal surface of the papillae but otherwise failed to display any preferential location pattern. A total of 262 taste buds, an average of 1.4 per papilla, were found. However, there was considerable variation in the occurrence of taste buds, both from papilla to papilla and from case to case. While the number of taste buds in a single papilla varied from 0 to 27, 63% of the papillae had no taste buds at all, 26% had 1-3 buds and the remainder 4 or more buds. The mean number of taste buds per papilla varied from 0 to 9 between individuals; no dependence upon sex or age could be demonstrated for this variation. The significance of these anatomical findings with regard to physiological studies on taste involving the fungiform papillae is discussed.

摘要

对22名年龄在2天至90岁之间的个体尸检时获取的182个菌状乳头连续切片进行了光镜检查,以观察味蕾的位置和数量。味蕾总是位于乳头的凸面、背侧表面,但在其他方面未显示出任何优先定位模式。总共发现了262个味蕾,每个乳头平均有1.4个。然而,味蕾的出现情况在乳头之间以及病例之间存在相当大的差异。单个乳头中的味蕾数量从0到27不等,63%的乳头根本没有味蕾,26%的乳头有1 - 3个味蕾,其余的有4个或更多味蕾。个体之间每个乳头的平均味蕾数量从0到9不等;无法证明这种差异与性别或年龄有关。讨论了这些解剖学发现对于涉及菌状乳头的味觉生理学研究的意义。
