Individual nerve fibers were traced on consecutive serial 1-micron-thick cross-sections to determine their position of origin within the horizontal ampullary nerve trunk (HANT) and the site at which they penetrated the basilar lamina of the horizontal crista in the guitarfish, Rhinobatos productus. Of the 132 fibers successfully traced, 87.1% followed an anatomical projection pattern consistent with the dynamic response characteristics of the nerve fibers. That projection pattern was: from the peripheral HANT region to the ipsilateral slope; from the central HANT region to the crest; and from the intermediate HANT region both to the ipsilateral slope and the crest of the horizontal crista. The 12.9% of "error" fibers not following this projection pattern were also consistent with the functional neurophysiological data. The terms crista bulbus and crista angustarum were introduced to designate specific anatomical regions of the dumb-bell shaped crista ampullaris.
在连续的1微米厚的横切面上追踪单个神经纤维，以确定它们在吉他鲨（Rhinobatos productus）水平壶腹神经干（HANT）内的起源位置，以及它们穿透水平嵴基底膜的部位。在成功追踪的132根纤维中，87.1%遵循与神经纤维动态反应特征一致的解剖投射模式。该投射模式为：从HANT外周区域到同侧斜坡；从HANT中央区域到嵴；从HANT中间区域到水平嵴的同侧斜坡和嵴。12.9%不遵循该投射模式的“错误”纤维也与功能性神经生理学数据一致。引入了球嵴和窄嵴这两个术语来指定哑铃形壶腹嵴的特定解剖区域。
