After injection of [3H]leucine into the nodose ganglion of a rabbit autoradiographic examination of the distribution of vagal afferent fibers in the epiglottal wall revealed many nerve bundles of labeled afferent fibers present in the submucosal plexus between the cartilage tissue and the mucosa. The labeled afferent fibers, most of which were myelinated (while a few were unmyelinated), descended towards the mucosa, and then appeared to demyelinate at the subepithelial layer of the mucosa. The labeled afferent fibers entered the mucosal epithelium, terminated as free endings in the intercellular space among the epithelial cells, and extended near the mucosal surface. Grains were also observed near the taste buds in the epithelium, which suggests that some vagal afferent fibers innervated the epiglottal taste buds.
将[3H]亮氨酸注入兔的结状神经节后，对会厌壁迷走传入纤维分布进行放射自显影检查发现，软骨组织与黏膜之间的黏膜下丛中有许多标记传入纤维的神经束。标记的传入纤维大多有髓鞘（少数无髓鞘），向下朝向黏膜，然后似乎在黏膜的上皮下层发生脱髓鞘。标记的传入纤维进入黏膜上皮，在上皮细胞间的细胞间隙中以游离末梢终止，并在黏膜表面附近延伸。在上皮中的味蕾附近也观察到银粒，这表明一些迷走传入纤维支配会厌味蕾。
