The sensory epithelium of the crista ampullaris can be divided both structurally and as regards sensitivity to noxious agents into a central and a peripheral zone. The question is, whether this differentiation is also reflected in the distribution of the two types of sensory cells. The present electron microscopic study, based on morphometric investigations of longitudinal and transverse sections through the crista, shows that in the guinea pig, the relative distribution of the two cell types is uniform throughout the sensory epithelium. There are about 60% type I and about 40% type II cells in both the central and peripheral areas of the crista.
壶腹嵴的感觉上皮在结构上以及对有害因子的敏感性方面均可分为中央区和外周区。问题在于，这种分化是否也反映在两种感觉细胞的分布上。基于对穿过嵴的纵切片和横切片的形态计量学研究的当前电子显微镜研究表明，在豚鼠中，两种细胞类型的相对分布在整个感觉上皮中是均匀的。在嵴的中央区和外周区，I型细胞约占60%，II型细胞约占40%。
