用冰冻断裂法对大鼠耳垂乳突的味蕾进行了光镜观察。紧密连接作为连接复合体位于味孔，并在口腔环境和味蕾之间形成密封。紧密连接不仅在味蕾内，而且在周围舌上皮的颗粒细胞层中。味孔的紧密连接可能与舌上皮的紧密连接。在芽中可以观察到桥粒，但它们的大小比周围的舌上皮小。除了这些连接外，在花蕾内，还显示了包含无粒子区的缝隙连接，这被称为小室类型。
The taste bud of the vallate papillae of the rat was examined with EM by the freeze-fracture technique. Tight junctions as a junctional complex are located at the taste pore, and form a seal between the oral environment and the taste buds. Tight junctions are not only within the taste buds, but are also in the granular cell layers of the surrounding lingual epithelium. The tight junctions of the taste pore may link with those of the lingual epithelium. Desmosomes are observed in the buds, but they are smaller in size than in the surrounding lingual epithelium. Besides these junctions, within the buds, gap junctions containing particle-free zones are demonstrated which are called a subcompartment type.
