Fig. 1
Diagrammatic representation of the testis showing a seminiferous tubule and the rete testis, the ductuli efferentes, the epididymis and vas deferens. The shaded regions indicate areas of the different segments of the epididymis, i.e., the initial segment, caput, corpus, and proximal and distal cauda, where data on the relative quantitative distribution of the major different epithelial cell types were obtained.

Light microscope photograph showing the sharp demarcation between the cuboidal epithelial cells of the rete testis (RT) and the columna epithelial cells of the efferent ducts (ED)
Fig. 3
Portion of the epithelium from the initial zone of an efferent duct at the light microscopic level showing numerous nonciliated cells (NC) and few ciliated cells (C)
Fig. 4
Portion of the epithelium from the terminal zone of an efferent duct showing nonciliated (NC) and ciliated (C) cells
Fig. 5
Light microscope photograph showing several tubules of the initial segment of the epididymis
Fig. 6
Portion of the epithelium lining the initial segment of the epididymis illustrating many tall columnar principal cells (P) with pale, round nuclei (n) located at different levels of the cell and showing a prominent nucleolus, a few elongated basal cells (B) at the base of the epithelium, and a deeply stained narrow cell (N). Longitudinal dense bands extend along the length of principal cells (arrowheads)
