The course of the nerve fibres and their nerve endings in the papillae on top of the intermolar rugae of rat's hard palate were studied by light- and electron-microscopy. Small myelinated and unmyelinated fibre bundles pass through the connective tissue of the basal region of the papilla, and split up in the intermediate region into solitary nerve fibres. In the top region only unmyelinated fibres were found. These fibres took the form of either lanceolate or free nerve endings. Some nerve endings made contact with the basement membrane of the epithelium. Occasionally free nerve endings were found between epithelial cells. The relationship of the unmyelinated fibres in the top of the papilla to the nerve fibres in the basal and intermediate regions was studied.
采用光镜和电镜研究了大鼠硬腭磨牙间嵴顶部乳头中神经纤维及其神经末梢的走行。有髓和无髓小纤维束穿过乳头基部区域的结缔组织，并在中间区域分成单根神经纤维。在顶部区域仅发现无髓纤维。这些纤维呈柳叶状或游离神经末梢的形式。一些神经末梢与上皮的基底膜接触。偶尔在上皮细胞之间发现游离神经末梢。研究了乳头顶部无髓纤维与基部和中间区域神经纤维的关系。
