In the nasopharynx, the larynx, the anal canal and the auditory tube, the "intermediate epithelium" occupied the transitional zone between the ciliated (or nonciliated) columnar epithelium and the stratified squamous one. The intermediate epithelium showed gradations ranging from stratified low-columnar through stratified cuboidal to stratified squamous type. It was suggested that the intermediate epithelium showed the various stages of the epithelium transforming from the columnar to the squamous epithelium, and that the basal cells of the columnar epithelium served as the germinal layer of the transformation.
在鼻咽部、喉部、肛管和咽鼓管中，“中间上皮”占据了纤毛（或无纤毛）柱状上皮与复层鳞状上皮之间的过渡区域。中间上皮呈现出从复层低柱状到复层立方状再到复层鳞状的渐变。有人提出，中间上皮显示了上皮从柱状向鳞状转化的各个阶段，并且柱状上皮的基底细胞作为转化的生发层。
