The taste buds from fungiform papillae and the hard palate of frogs were investigated with the scanning and transmission electron microscopes. An immature pre-taste cell and a mature taste cell can be differentiated. Only the mature taste cell exhibits synaptic contact with the afferent taste fibre. Glandular and satellite supporting cells envelop the thin apical processes of the sensory cells. At the base of the taste disc up to 10 Merkel cells form a complex with nerve endings. There are two types of myelinated fibres, large and small. The small fibre innervates the taste cells, the thicker nerve fibre the Merkel cells. The occurrence of two types of receptors explains physiological results.
用扫描电子显微镜和透射电子显微镜对青蛙菌状乳头和硬腭的味蕾进行了研究。可以区分出未成熟的前味觉细胞和成熟的味觉细胞。只有成熟的味觉细胞与传入味觉纤维表现出突触联系。腺性支持细胞和卫星支持细胞包裹着感觉细胞纤细的顶端突起。在味盘底部，多达10个默克尔细胞与神经末梢形成复合体。有两种有髓纤维，即大的和小的。小纤维支配味觉细胞，较粗的神经纤维支配默克尔细胞。两种受体的存在解释了生理学结果。
