Morphological study has been done in touch domes of hamster cheek pouch as a preparation for further electrophysiological study. The touch domes were examined by light and electron microscopy. There were one or two primary ridges (epithelial ridges) in the center of the touch dome, and each dome was supplied by one to three nerve fibres. Tactile cells (Merkel cells) were localized within primary ridges of touch domes and Merkel cell-neurite complexes were observed in every one. Since Merkel cell-neurite complexes are slow adapting mechanoreceptors, these results suggest that they might be involved in touch sensation.
作为进一步电生理研究的准备工作，已对仓鼠颊囊的触穹进行了形态学研究。通过光学显微镜和电子显微镜对触穹进行了检查。在触穹的中心有一到两条初级嵴（上皮嵴），每个触穹由一到三条神经纤维供应。触觉细胞（默克尔细胞）位于触穹的初级嵴内，并且在每个触穹中都观察到了默克尔细胞 - 神经突复合体。由于默克尔细胞 - 神经突复合体是慢适应机械感受器，这些结果表明它们可能参与触觉感受。
