The three-dimensional architecture of the subepithelial connective tissue layer in the mouse retromolar region was studied by scanning electron microscopy after removal of the epithelial layer. The connective tissue papillae (CTP) of the taste bud papillae (the retromolar papillae) appeared as a barnacle-like in form and had the round depression, corresponding to the site of taste bud, on their top. The CTP of the retromolar papillae and the openings of the salivary glands were concentrated collectively in the narrow zone just posterior to the molar teeth. This topographical relationship seems to reflect a physiological function; i.e., the food ground by the molar teeth is dissolved in saliva and stimulates the taste buds in the retromolar papillae. Further, the conical or cylindrical CTP were arranged around the CTP of the retromolar papillae. It is suggested that the conical or cylindrical CTP play an important role in increasing the epithelial-connective tissue interface and in resisting the excessive force during mastication.
去除上皮层后，通过扫描电子显微镜研究了小鼠磨牙后区上皮下结缔组织层的三维结构。味蕾乳头（磨牙后乳头）的结缔组织乳头（CTP）呈藤壶状，顶部有对应味蕾部位的圆形凹陷。磨牙后乳头的CTP和唾液腺开口共同集中在磨牙后方的狭窄区域。这种地形关系似乎反映了一种生理功能，即磨牙磨碎的食物溶解在唾液中，并刺激磨牙后乳头中的味蕾。此外，圆锥形或圆柱形的CTP围绕着磨牙后乳头的CTP排列。提示圆锥形或圆柱形CTP在增加上皮-结缔组织界面以及抵抗咀嚼过程中的过度力量方面发挥重要作用。
